After completing installation, test the unit to check for installation errors. Give the user adequate instructions conceming the use and cleaning

of the unit according to the Operation Manual.

Installation should be left to the dealer or another professional.

Improper installation may cause water leakage, electrical shock, or fire.

Install the air conditioner according to the instructions given in this manual.

Incomplete installation may cause water leakage, electrical shock, or fire.

Be sure to use the suplied or specified installation parts.

Use of other parts may cause the unit to cometo lose, water leakage, electrical shock, or fire.

Install the air conditioner on a solid base that can support the unit's weight.

An inadequate base or incomplete installation may cause injury in the event the unit falls off the base.

Electrical work should be carried out in accordance with the installation manual and the national electrical wiring rules or code of practice.

Insufficient capacity or incomplete electrical work may cause electrical shock or fire.

Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance.

For wiring, use a cable long enough to cover the entire distance with no connection.

Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit.

(Failure to do so may cause abnormal heat, electric shock or fire.)

Use the specified types of wires for electrical connections between the indoor and outdoor units.

Firmly clamp the interconnectiong wires so their terminals terminals receive no external stresses. Incomplete connections or clamping may cause terminal overheating or fire.

After connectiong interconnecting and supply wiring be sure to shape the cables so that they do not put undue force on the electrical

covers or panels.

Install covers over the wires. Incomplete cover installation may cause terminal overheating, electrical shock, or fire.

If any refrigerant has leaked out during the installation work, ventilate the room.

(The refrigerant produces a toxic gas if exposed to flames.)

After all installation is complete, check to make sure that no refrigerant is leaking out.

(The refrigerant produces a toxic gas if exposed to flames.)

When installing or relocating the system, be sure to keep the refrigerant circuit free from substancs other than the specified

refrigerant(R410A), such as air.

(Any presence of air or other foreign substance in the refrigerant circuit causes an abnormal pressure rise or rupture, resulting in injury.)

During pump-down, stop the compressor before removing the refrigerant piping.

If the compressor is still running and the stop valve is open during pump-down, air will be sucked in when the rcompressor is run, causing abnormal pressure in the freezer

cycle which will lead to breakage and even injury.

Be sure to establish an earth. Do not earth the unit to a utility pipe, arrester, or telephone earth.

In complete earth may cause electrical shock, or fire. A high surge current from lightning or other sources may cause damage to the air conditioner.

Be sure to install an earth leakage breaker.

Failure to install an earth leakage breaker may result in electric shocks, or fire.

Do not install the aire conditioner in a place where there is danger of exposure to inflammable gas leakage.

If the gas leaks and builds up around the unit, it may catch fire.

Establish drain piping according to the instructions of this manual.

Inadequate piping may cause flooding.

Tighten the flare nut according to the specified method such as with a torque wrench.

If the flare nut is tightened too hard, the falre nut may crack after a long time and cause refrigerant leakage.

Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter by small animals.

Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct the customer to keep the area around the unit clean.

ground to prevent burying in snow.

Accessories supplied with the outdoor unit:

1) Choose a place solid enough to bear the weight and vibration of the unit, where the operation noise will not be amplified.

2) Choose a location where the hot aire discharged from the unit or the operation noise, will not cause a nuisance to the neighbors of the

user.

3) Avoid places near a bedroom and the like, so that the operation noise will cause no trouble.

4) There must be sufficient space for carrying the unit into and out of the site.

5) There must be sufficient space for air passage and no obstructions around the air inlet and the air outlet.

6) The site must be free from the possibility of flammable gas leakage in a nearby place.

Locate the unit so that the noise and the discharged hot air will not annoy the neighbors.

7) Install units, power cords and inter-unit cables at least 3 meter away from television and radio sets. This is to prevent interference to

images and sounds. (Noises may be heard even if they are more than 3 meter away depending on radio wave conditions.)

8) In coastal areas or other places with salty atmosphere of sulfate gas, corrosion may shorten the life of the air conditioner.

9)Since drain flows out of the outdoor unit, do not place under the unit anything which must be kept away from moisture.

Cannot be installed hanging from ceiling or stacked.

When operationg the air conditioner in a low outdoor ambient

temperature, be sure to follow the instructions described below.

1) To prevent exposure to wind, install the outdoor unit with its suction

side facing the wall.

2) Never install the outdoor unit at a site where the suction side may be

exposed directly to wind.

4. Purging air and checking gas leakage

WARNING

3. Refrigerant piping work

When piping work is completed, it is necessary to purge the air and check for gas leakage.

1) Do not mix any substance other than the specified refrigerant (R410A) into the refrigeration cycle.

2) When refrigerant gas leaks occur, ventilate the room as soon and as much as possible.

3) R410A, as well as other refrigerants, should always be recovered and never be released directly into the environment.

4) Use a vacuum pump for R410A exclusively. Using the same vacuum pump for different refrigerents may damage the vacuun pump

or the unit.

If using additional refrigerant, perform air purging from the refrigerant pipes and indoor unit using a vacuum pump, then charge additional

refrigerant.

Use a hexagonal wrench (4mm) to operate the stop valve rod.

All refrigerant pipe joints should be tightened with a torque wrench at the specified tightening torque.

Connect projection side of charging hose(Which comes from gauge manifold) to gas stop valve's service port.

Fully open gauge manifold's low-pressure valve(Lo) and completely close its high-pressure valve(Hi).

(High-pressure valve subsequently requires no operation.)

Apply vacuum pumping. Check that the compound pressure gauge reads-0.1MPa(-76cmHg).

Evacuation for at lease 1 hour is recommended.

Close gauge manifold's low-pressure valve(Lo) and stop vacuum pump.

(Leave as is for 4-5 minutes and make sure the coupling meter needie does not go back.

If it does go back, this may indicate the presence of moisture or leaking from connecting parts. After inspecting all the connection and

loosening then retightening thenuts, reqeat steps 2-4. )

Remove covers from liquid stop valve and gas stop valve.

Turn the liquid stop valve's rod 90 degrees counterclockwise with a hexagonal wrench to open valve.

Close it after 5 seconds, and check for gas leakage.

Using soapy water, check for gas leakage from indoor unit's flare and outdoor unit's flare and valve rods.

After the check is complete, wipe all soapy water off.

Disconnect charging hose from gas stop valve's service port, then fully open liquid and gas stop valves.

(Do not attempt to turn valve rodj beyond its stop.)

Tighten valve caps and service port caps for the liquid and gas stop valves with a torque wrench at the specified torques. See "3

Refrigerant piping " on page 6 for details.

7.Precautions for Laying Refrigerant Piping

Cautions on pipe handling

1) Protect the open end of the pipe against dust and moisture.

2) All pipe bends should be as gentle as possible. Use a pipe bender for bending.(Bending radius should be 30 to 40mm or larger.)

Selection of copper and heat insulation materials

When using commercial copper pipes and fittings, observe the following :

1) Insulation material: Polyethylene foam

Heat transfer rate: 0.041 to 0.052W/mK(0.035to 0.045kcal/mh

o

C)

Refrigerant gas pipe's surface temperature reaches 110

o

C max.

Choose heat insulation materials that will withstand this temperature.

2) Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.

Check the type of refrigerant to be used on the machine namiplate.

Precautions when adding R410A

Fill from the liquid pipe in liquid form.

It is a mixed refrigerant, so adding it in gas form may cause the refrigerant composition to change, preventing normal operation.

1) Before filling, check whether the cylinder has a siphon attached or not.(It should have something like "liquid filling siphon attached"

displayed on it.)

2) Be sure to use the R410A tools to ensure pressure and to prevent foreign objects entering.

1) This system must use refrigersant R410A.

2) Add refrigerant 20g per meter when the total piping length

exceeds the standard value, but make sure that the total liquid

piping length should be less than the max. value.

1) When using this product, you need not to set the address. But the L/N wires between indoor & outdoor units must be corresponded,

or there will be communication failure.

2) Quiet Operation Setting. Set the DIP "8" to ON position of SW5, the system will run with lower noise, but the max. capacity will also

reduce slightly.

3) Do not change the settings of other switchs, wrong settings can make the system damage or other malfunctions.

Refrigerant piping work

Filling a cylinder with an attached siphon

Stand the cylinder upright when filling.

There is a siphon pipe inside, so the

cylinder need not be upside-down

to fill with liquid.

Filling other cylinders

Turn the cylinder upside-down

when filing.
