= The water softener requires a minimum water flow of 3 gallons per minute at the inlet. Maximum allowable inlet

water pressure is 125 psi. If your house water pressure is over the maximum, install a pressure reducing valve in

the water supply pipe to the system (Adding a pressure reducing valve may reduce the flow). If your home is

equipped with a back flow preventer, an expansion tank must be installed in accordance with local codes and laws.

= The water softener works on 24V DC electrical power, supplied by a direct plug-in power supply (included). Be

sure to use the included power supply and plug it into a nominal 120V, 60 Hz household outlet that is in a dry

location only, grounded and properly protected by an overcurrent device such as a circuit breaker or fuse.

= Do not use this system to treat water that is microbiologically unsafe or of unknown quality without adequate dis-

infection upstream or downstream of the system.

European Directive 2002/96/EC requires all electrical and electronic equipment to be disposed of accord-

ing to Waste Electrical and Electronic Equipment (WEEE) requirements. This directive or similar laws are

in place nationally and can vary from region to region. Please refer to your state and local laws for prop-

er disposal of this equipment.

Before You Start

*Intermittent flow rate does not represent the maxi-

mum service flow rate used for detemining the con-

ditioner’s rated capacity and efficiency. Continuous

operation at flow rates greater than the service flow

rate may affect capacity and efficiency performance.

**Typical residential chlorine concentration is 0.5 to 1.0

ppm.

Variable Salt Dose: The salt dose is selected by

the electronic controls at regeneration time based

on the amount needed.

LOCATION REQUIREMENTS

Consider all of the following when selecting an installa-

tion location for the water softener.

= Do not locate the water softener where freezing

temperatures occur. Do not attempt to treat water

over 120ºF. Freezing temperatures or hot water

damage voids the warranty.

= To condition all water in the home, install the water

softener close to the water supply inlet, and

upstream of all other plumbing connections, except

outside water pipes. Outside faucets should remain

on hard water to avoid wasting conditioned water

and salt.

= A nearby drain is needed to carry away regenera-

tion discharge (drain) water. Use a floor drain,

laundry tub, sump, standpipe, or other options

(check your local codes). See "Air Gap

Requirements" and "Valve Drain Requirements"

sections.

= The water softener works on 24V DC electrical

power, supplied by a direct plug-in power supply

(included). Provide nearby a 120V, 60 Hz electrical

outlet, in accordance with national and local codes.

= Always install the water softener between the water

inlet and water heater. Any other installed water

conditioning equipment should be installed between

the water inlet and water softener (See Figure 3

below).

= Avoid installing in direct sunlight. Excessive sun

heat may cause distortion or other damage to non-

metallic parts.

In the state of Massachusetts: The Commonwealth

of Massachusetts plumbing code 248-CMR shall

be adhered to. A licensed plumber shall be used

for this installation.

AIR GAP REQUIREMENTS

A drain is needed for regeneration water (See Figure

2). A floor drain, close to the water softener, is pre-

ferred. A laundry tub, standpipe, etc. are other drain

options. Secure valve drain hose in place. Leave an

air gap of 1-1/2” between the end of the hose and the

drain. This gap is needed to prevent backflow of

sewer water into the water softener. Do not put the

end of the drain hose into the drain.

VALVE DRAIN REQUIREMENTS

Using the flexible drain hose (included), measure and

cut to the length needed. Flexible drain hose is not

allowed in all localities (check your plumbing codes). If

local codes do not allow use of a flexible drain hose, a

rigid valve drain run must be used. Purchase a com-

pression fitting (1/4 NPT x 1/2” minimum tube) and

1/2” tubing from your local hardware store. Plumb a

rigid drain as needed (See Figure 5).

NOTE: Avoid drain hose runs longer than 30 feet.

Avoid elevating the hose more than 8 feet

above the floor. Make the valve drain line as

short and direct as possible.

INLET / OUTLET PLUMBING OPTIONS

Always install either a single bypass valve (provided),

as shown in Figure 6, or, if desired, parts for a 3 valve

bypass system (not included) can be purchased and

assembled, as shown in Figure 7. Bypass valves

allow you to turn off water to the softener for mainte-

nance if needed, but still have water in house pipes.

Pipe fittings must be 3/4” minimum.

Use:

= Copper pipe

= Threaded pipe

= PEX (Crosslinked Polyethylene) pipe

= CPVC plastic pipe

= Other pipe approved for use with potable water

IMPORTANT: Do not solder with plumbing attached to

installation adaptors and single bypass

valve. Soldering heat will damage the

adaptors and valve.

Installation Instructions

TURN OFF WATER SUPPLY

1. Close the main water supply valve, located near the

well pump or water meter.

2. Shut off the electric or fuel supply to the water

heater.

3. Open all faucets to drain all water from house pipes.

NOTE: Be sure not to drain water from the water

heater, as damage to the water heater ele-

ments could result.

ASSEMBLY

1. North Star models are factory assembled. During

installation, remove the salt lid and set it aside to

prevent damage. Check the brinewell to be sure it

is secured and vertical (See Figure 11). Unsnap the

faceplate cover to expose the softener valve assem-

bly.

2. Lift the brine valve out of the brinewell. Make sure

the float stem is parallel to the stand tube so the

seals will seat properly during operation. Place the

brine valve back into the bottom of the brinewell and

reinstall the brinewell cover.

3. Install the brine tank overflow grommet and elbow

into the 13/16” diameter hole in the back of the salt

storage tank wall.

MOVE THE UNIT INTO PLACE

1. Move the water softener into the desired location.

Set it on a solid, level surface.

IMPORTANT: Do not place shims directly under the

salt storage tank to level the softener.

The weight of the tank, when full of

water and salt, may cause the tank to

fracture at the shim.

2. Visually check and remove any debris from the

ater softener valve inlet and outlet ports.

. Make sure the turbine assembly spins freely in the

"out" port of the valve (See Figure 9).

4. If not already done, put a light coating of silicone

grease on the single bypass valve o-rings.

5. Push the single bypass valve into the softener valve

as far as it will go. Snap the two large holding clips

into place, from the top down as shown in Figures

12 & 13.

IMPORTANT: Be sure the clips snap firmly into place

so the single bypass valve will not pull

out.

COMPLETE INLET AND OUTLET PLUMBING

Measure, cut, and loosely assemble pipe and fittings

from the main water pipe to the inlet and outlet ports of

the water softener valve. Be sure to keep fittings fully

together, and pipes squared and straight.

Be sure hard water supply pipe goes to the water sof-

tener valve inlet side.

NOTE: Inlet and outlet are marked on the water sof-

tener valve. Trace the water flow direction to

be sure hard water is to inlet.

IMPORTANT: Be sure to fit, align and support all

plumbing to prevent putting stress on

the water softener valve inlet and outlet.

Undue stress from misaligned or unsup-

ported plumbing may cause damage to

the valve.

Complete the inlet and outlet plumbing for the type of

pipes you will be using.

ALTERNATE BYPASS VALVE INSTALLATION

If connecting to floor

level plumbing, install

the bypass valve turned

downward, as shown.

OUT

FIG. 10

Installation Instructions

INSTALL SALT STORAGE TANK OVER-

FLOW HOSE

1. Measure, cut to needed length and connect the 3/8”

drain line (provided) to the salt storage tank over-

flow elbow and secure in place with a hose clamp.

2 Route the hose to the floor drain, or other suitable

drain point no higher than the drain fitting on the salt

storage tank (This is a gravity drain). If the tank

overfills with water, the excess water flows to the

drain point. Cut the drain line to the desired length

and route it neatly out of the way.

IMPORTANT: For proper operation of the water soften-

er, do not connect the water softener

valve drain tubing to the salt storage

tank overflow hose.

TEST FOR LEAKS

To prevent air pressure in the water softener and

plumbing system, complete the following steps in

order:

1. Fully open two or more softened cold water faucets

close to the water softener, located downstream

from the water softener.

2. Place the bypass valve (single or 3 valve) into the

"bypass" position. See Figures 6 & 7 on Page 5.

3. Slowly open the main water supply valve. Run

water until there is a steady flow from the opened

faucets, with no air bubbles.

4. Place bypass valve(s) in "service" or soft water posi-

tion as follows:

= Single bypass valve: Slowly move the valve stem

toward "service," pausing several times to allow

the water softener to fill with water.

= 3 valve bypass: Fully close the bypass valve and

open the outlet valve. Slowly open the inlet

valve, pausing several times to allow the water

softener to fill with water.

5. After about three minutes, open a hot water faucet

until there is a steady flow and there are no air bub-

bles, then close this faucet.

6. Close all cold water faucets and check for leaks at

the plumbing connections that you made.

7. Check for leaks around clips at softener’s inlet and

outlet. If a leak occurs at a clip, depressurize the

plumbing (turn off the water supply and open

faucets) before removing clip. When removing clips

at the softener’s inlet or outlet, push the single

bypass valve body toward the softener (See Figure

15). Improper removal may damage clips. Do not

reinstall damaged clips.

INSTALL VALVE DRAIN HOSE

NOTE: See valve drain options on page 4.

1. Measure, cut to needed length and connect the 3/8”

drain line (provided) to the water softener valve

drain fitting. Use a hose clamp to hold the hose in

place.

IMPORTANT: If codes require a rigid drain line see

“Valve Drain requirements" section.

2. Run the drain hose (or a rigid line) to the floor drain.

Secure drain hose. This will prevent “whipping'' dur-

ing regenerations. Be sure to provide a 1-1/2” min -

imum air gap to prevent possible sewer water

backup. See “Air Gap Requirements" section.

NOTE: In addition to a floor drain, you can use a laun-

dry tub or standpipe as a good drain point for

this hose.. Avoid long drain hose runs, or ele-

vating the hose more than 8 feet above the

floor.

FIG. 14

Ground Wire

GROUNDING INFORMATION

(for Installations on Metal Pipe)

The house main incoming water pipe is often used to

ground electrical outlets in the home. Grounding pro-

tects you from electrical shock. Installing the water

softener with a plastic bypass valve will break this

ground. Before beginning installation, purchase and

securely install two grounding clamps and a #4 copper

wire across the location where the softener will be,

tightly clamping it at both ends, as shown in Figure 14.

NOTE: Check local plumbing and electrical codes

for proper installation of the ground wire.

The installation must conform to them. In

Massachusetts, plumbing codes of

Massachusetts shall be conformed to.

Consult with your licensed plumber.

Installation Instructions

ADD WATER AND SALT TO THE SALT

STOR AGE TANK

1. Using a container, add about three gallons of clean

water into the salt storage tank.

2. Add salt to the storage tank. Use nugget, pellet or

coarse solar salts with less than 1% impurities.

PLUG IN THE POWER SUPPLY

During installation, the water softener wiring may be

moved or jostled from place. Be sure all leadwire con-

nectors are secure on the back of the electronic board

and be sure all wiring is away from the valve gear and

motor area, which rotates during regenerations.

1. Plug the power supply into an electrical outlet that is

not controlled by a switch.

PROGRAM THE CONTROLLER

1. Install the softener’s top cover and salt lid.

2. Complete the programming steps on Page 10.

SANITIZE THE WATER SOFTENER /

SANITIZE AFTER SERVICE

Care is taken at the factory to keep your unit clean and

sanitary. Materials used to make the unit will not infect

or contaminate your water supply, and will not cause

bacteria to form or grow. However, during shipping,

storage, installation and operation, bacteria could get

into the unit. For this reason, sanitizing as follows is

suggested* when installing.

1. Slide open the salt lid, remove the brinewell cover

and pour about 3 oz. (6 tablespoons) of household

bleach into the softener brinewell. Replace the

brinewell cover.

2 Make sure the bypass valve(s) is in the “service”

(open) position.

3 Start a recharge: Press the RECHARGE button and

hold for 3 seconds, until “Recharge Now” begins to

flash in the display. This recharge draws the sanitiz-

ing bleach into and through the water softener. Any

air remaining in the unit is purged to the drain.

4. After the recharge has completed, fully open a cold

water faucet, downstream from the softener, and

allow 50 gallons of water to pass through the sys-

tem. This should take at least 20 minutes. Close

the faucet.

*Recommended by the Water Quality Association. On some

water supplies, the unit may need periodic disinfecting.

RESTART THE WATER HEATER

1. Turn on the electricity or fuel supply to the water

heater and relight the pilot, if applicable.

NOTE: The water heater is filled with hard water and,

as hot water is used, it refills with conditioned

water. In a few days, the hot water will be fully

conditioned. To have fully conditioned hot

water immediately, wait until the initial recharge

(previous step) is over. Then, drain the water

heater (following instructions for water heater)

until water runs cold.

2. Press the UP (È) or DOWN (–) buttons to enter

the hardness of your water supply in grains per gallon

(gpg)

NOTE: If your water supply contains iron, compen-

sate for it by adding to the water hardness

number. For example, assume your water is

20 gpg hard and contains 2 ppm iron. Add 5

to the hardness number for each 1 ppm of

iron. In this example, you would use 30 for

your hardness number.

START A RECHARGE

1. Press the RECHARGE button and hold for three

seconds, until “RECHARGE” begins to flash in the

display, starting a recharge. This recharge draws

the sanitizing bleach into and through the water

softener. Any air remaining in the water softener is

purged to the drain. During this time, periodically

check for leaks.

NOTE: As with all other water system applications,

leaks may occur. Leaks may not be immedi-

ately apparent. Recheck for leaks 24 hours

after first recharge cycle is complete.

POWER OUTAGE MEMORY

If electrical power to the water softener is lost, “mem-

ory'' built into the timer circuitry will keep all settings

for several hours. While the power is out, the display

is blank and the water softener will not regenerate.

When electrical power is restored, the following will

occur:

Reset the present time only if the display is flashing.

The HARDNESS and RECHARGE TIME never

require resetting unless a change is desired. Even if

the clock is incorrect after a long power outage, the

softener operates as it should to keep your water soft.

However, regenerations may occur at the wrong time

of day until you reset the clock to the correct time of

day.

NOTE: If the water softener was regenerating when

power was lost, it will now finish the cycle.

RECHARGE NOW initiated

RECHARGE NOW

The RECHARGE button is used to initiate an immedi-

ate recharge.

1. Press and hold the RECHARGE button until the

words “RECHARGE NOW" flash in the display.

The softener enters the fill cycle of regeneration right

away. “RECHARGE NOW” will flash during the

regeneration. When completed, full water condition-

ing capacity is restored..

NOTE: Avoid using hot water while the softener is

regenerating, because the water heater will

refill with bypass hard water.

RECHARGE TONIGHT

If you do not want to start an immediate recharge, but

would like to schedule an extra recharge at the next

preset recharge time, do the following:

1. Press and release (do not hold) the RECHARGE

button.

The words “RECHARGE TONIGHT" flash in the dis-

play, and the softener will recharge at the next

recharge time. The words “RECHARGE NOW" will

flash during the regeneration. When completed, full

water conditioning capacity is restored.

2. If you want to change the recharge start time,

press the UP (È) or DOWN (–) buttons until the

desired time shows. Be sure AM or PM is correct.

3. Press the SET button five times to return to the

normal run display (See Fig. 19).

VACATION NOTE

North Star demand water softeners, as set at the fac-

tory, recharge only while water is being used and soft-

ening capacity must be restored. For this reason, the

softener will not recharge when you are away from

home for extended periods. However, if you set the

“Maximum Days Between Recharges” feature, the

softener will regenerate even when no water is used.

MAXIMUM DAYS BETWEEN REGENERA-

TIONS

The water softener automatically controls regenera-

tion frequency. This provides the greatest operating

efficiency and, under most conditions, this feature

should be left in this automatic mode. However, you

may modify this feature if you want to force a regen-

eration every set number of days. For example, if

your water supply contains clear water iron, you may

want the softener to regenerate every few days to

keep the resin bed clean. The maximum days

between recharges may be set from 1 to 15 days, as

follows:

NOTE: The softener will recharge on its own if need-

ed, even if it is before the set number of days.

1. Press the SET button and hold for three seconds,

until the “Recharge Time” screen (Figure 26) is dis-

played.

2. Once in this display, press the SET button again

and the display in Figure 27 is shown.

Water Softener Maintenance

REFILLING WITH SALT

Brine (salt dissolved in water) is needed for every

regeneration. The water for making brine is metered

into the salt storage area by the softener valve and

timer. If the water softener uses all the salt before

more is added, hard water will result. Lift the brine

tank lid and check the salt level every week. Be sure

that the brinewell cover is on when adding salt.

NOTE: In humid areas it is best to keep the salt level

less than half full and refill more often.

RECOMMENDED SALT: Cube, pellet, coarse solar,

etc., water softener salt is recommended. This type

of salt is high purity evaporated crystals, sometimes

formed and pressed into briquets. It has less than

1% insoluble (not dissolvable in water) impurities.

Clean, high grade rock salts are acceptable, but may

require frequent brine tank cleaning to remove the

“sludge” residue (insolubles) collecting at the bottom

of the tank.

SALT NOT RECOMMENDED: Rock salt high in

impurities, block, granulated, table, ice melting, or ice

cream making salts, etc., are not recommended.

SALT WITH IRON REMOVING ADDITIVE: Some

salts have an additive to help a water softener handle

iron in the water supply. Although this may help keep

the resin bed clean, it may also release corrosive

fumes that will weaken and shorten the life of some

water softener electronic parts.

BREAKING A SALT BRIDGE

Sometimes a hard crust or salt “bridge” forms in the

brine tank. This is usually caused by high humidity or

the wrong kind of salt. When the salt bridges, an

empty space forms between the water and the salt.

Then salt will not dissolve in the water to make brine.

Without brine, the resin bed is not recharged and

hard water will result.

If the storage tank is full of salt, it is difficult to tell

whether there is a salt bridge. A bridge may be

underneath loose salt. The following is the best way

to check for a salt bridge:

Salt should be loose all the way to the bottom of the

tank. Hold a broom handle, or like tool, up to the sof-

tener, as shown in Figure 35. Make a pencil mark on

the handle 1-2” below the top of the rim. Then, care-

fully push it straight down into the salt. If a hard

object is felt before the pencil mark is even with the

top, it is most likely a salt bridge. Carefully push into

the bridge in several places to break it. Do not try to

break the salt bridge by pounding on the outside

of the salt tank. You may damage the tank.

Water Softener Maintenance

CLEANING THE NOZZLE & VENTURI

clean nozzle & venturi (See Figure 36) is necessary

or the water softener to work properly. This small

nit creates the suction to move brine from the brine

ank into the resin tank. If it should become plugged

ith dirt, silt, sand, etc., the water softener will not

work and hard water will result.

To get access to the nozzle & venturi, remove the

softener’s top cover. Put the bypass valve(s) into the

bypass position. Be sure the softener is in the serv-

ice cycle (no water pressure at the nozzle & venturi).

Then, holding the nozzle & venturi housing with one

hand, turn the cap to remove it. Do not lose the o-

ring seal. Lift out the screen support and screen.

Then, remove the nozzle & venturi. Wash the parts in

warm, soapy water and rinse in fresh water. If need-

ed, use a small brush to remove iron or dirt. Be care-

ful not to scratch, misshape, etc., surfaces of the noz-

zle & venturi. Also, check and clean the gasket and

flow plug(s) if dirty.

Carefully replace all parts in the correct order.

Lubricate the o-ring seal with silicone grease and put

in place. Install and tighten the cap, by hand only.

Do not overtighten, which could break the cap or

housing. Put the bypass valve(s) into service (soft

water) position.

RESIN BED CLEANING

If the water supply contains clear water iron, regular

resin bed cleaning is needed to keep the bed from

coating with iron. Use resin bed cleaner, following

directions on the container. Clean the resin every six

months, or more often if iron appears in the condi-

tioned water supply.

TROUBLESHOOTING GUIDE

TROUBLESHOOTING - INITIAL CHECKS

Always make these initial checks first:

1. Is display blank? Check power source.

2. Is Error code displayed? If so, go to “Automatic

Electronic Diagnostics” on the next page.

3. Is correct time displayed? If not, recharges occur at

the wrong time. Set the present time (See Page 10.)

4. Is there salt in the brine tank? If not, refill.

5. Is salt “bridged” (See Page 15)?

6. Are plumbing bypass valve(s) in service position?

7. Are inlet and outlet pipes connected to the water sof-

tener inlet and outlet respectively?

8. Is valve drain hose free of kinks and sharp bends,

and not elevated over 8 feet above the floor.

9. Is the brine tube connected?

10. Check the hardness setting (See “Setting Hardness

on Page 10). Be sure it is correct for the house-

hold's water supply. Perform a hardness test on a

raw water sample to compare with the setting.

11. Perform a hardness test on a softened water sam-

ple to determine whether a problem exists.

If no problem is found after making the initial checks,

proceed to “Manually Initiated Electronic Diagnostics”

on the next page.

Troubleshooting

While an error code appears in the display, all buttons

are inoperable except the SET button. SET remains

operational so the service person can perform the

Manually Initiated Electronic Diagnostics, see below,

to further isolate the problem.

Procedure for removing error code from dis-

play:

1. Unplug power supply from electrical outlet.

2. Correct problem.

3. Plug power supply back in.

4. Wait 8 minutes. The error code will return if

the problem was not corrected.

MANUALLY INITIATED ELECTRONIC

DIAGNOSTICS

Use the following procedures to advance the water

softener through the regeneration cycles to check

operation.

Lift off the salt lid, remove the top cover by unlocking

the tabs in the back and rocking forward, to observe

cam and switch operation during valve rotation.

1. Press and hold

the DATA button for 3 seconds until

one of the two displays in Figure 39 is shown, then

release. The number in the top part of the display,

after “dY”, is days since the last recharge.

NOTE: If the softener is in the middle of a regenera-

tion, the top part of the display shows the

cycle of regeneration, and minutes of the

cycle remaining. If two cycle names are flash-

ing, the valve is in transition between the

cycles.

2. The 3 digits under WATER MANAGEMENT SYS-

TEM indicate water meter operation as follows:

000 (steady) = Soft water not in use, and no flow

through the meter.

Open a nearby soft water faucet.

000 to 199 (continual) = Repeats for each gallon

of water passing through

the meter.

3. Symbols in the display indicate POSITION switch

operation (See Figure 39).

4. Use the RECHARGE button to manually advance

the valve into each cycle and check correct switch

operation.

NOTE: Be sure water is in contact with the salt, and

not separated by a salt bridge (See "Breaking

A Salt Bridge" section).

5. Press the DATA button again. The following infor-

mation is available and may be beneficial for vari-

ous reasons. This information is retained by the

computer from the first time electrical power is

applied to the face plate.

Troubleshooting

This check verifies proper operation of the valve

rates, and other controller functions. Always make

the initial checks, and the manual initiated diagnos-

tics.

NOTE: The electronic control display must show a

steady time (not flashing). If an error code

MANUAL ADVANCE REGENERATION CHECK

hows, first press the SET button to enter the

diagnostic display.

1. Press the RECHARGE button and hold

in for 3

econds. RECHARGE begins to flash as the soft-

ener’s valve advances from the service to fill posi-

ion. Remove the brinewell cover and, using a

flashlight, observe fill water entering the tank.

If water does not enter the tank, look for an

obstructed nozzle, venturi, fill flow plug, brine tub-

ing, or brine valve riser pipe.

2. After observing fill, press the RECHARGE button to

move the softener’s valve into the brine position. A

slow flow of water to the drain will begin. Verify

brine draw from the brine tank by shining a flash-

light into the brinewell and observing a noticeable

drop in the liquid level. This may take 15 to 20

minutes.

NOTE: Be sure water is in contact with the salt, and

not separated by a salt bridge (See "Breaking

A Salt Bridge" section).

If the water softener does not draw brine, check for

(most likely to least likely):

= Dirty or plugged nozzle and venturi, see

"Cleaning the Nozzle and Venturi" section.

= Nozzle and venturi not seated on the gasket, or

gasket deformed.

= Valve seals leaking (See Troubleshooting).

= Restriction in valve drain, causing a back-pres-

sure (bends, kinks, elevated too high, etc.). See

"Install Valve Drain Hose" section.

= Obstruction in brine valve or brine tubing.

NOTE: If water system pressure is low, a too-long or

elevated drain hose may cause back pres-

sure, stopping brine draw. Avoid drain hose

runs longer than 30 feet. Avoid elevating the

hose more than 8 feet above the floor.

3. Press the RECHARGE button to move the soften-

er’s valve into the backwash position. Look for a

fast flow of water from the drain hose. Check that

the drain can adequately handle the flow and vol-

ume.

An obstructed flow indicates a plugged top distribu-

tor, backwash flow plug, or drain hose.

4. Press the RECHARGE button to move the soften-

er’s valve into the fast rinse position. Again look

for a fast drain flow. Allow the softener to rinse for

a few minutes to flush out any brine that may

remain in the resin tank from the brining cycle test.

5. To return the softener’s valve to the service posi-

tion, press the RECHARGE button.

RESETTING TO FACTORY DEFAULTS

To reset the electronic controller to its factory default

for all settings (time, hardness, etc.):

1. Press the SET button and hold it until the display

changes twice to show the flashing model code.

2. Press the UP (È) button (a few times, if necessary)

to display a flashing “SoS”.

3. Press the SET button three times, and the elec-

tronic controller will restart.

4. Set the present time and hardness, as described

on page 10.
