Piping length and elevation
If the pipe is too long, both the capacity and reliability of
the unit will drop. As the number of bends increases,
resistance to the flow of refrigerant system increases, thus
lowering cooling capacity. As a result the compressor may
become defective. Always choose the shortest path and
follow the recommendations as tabulated below:
Remark: The refrigerant pre-charged in the outdoor unit
is for piping length up to 7.62m/25ft.
REFRIGERANT PIPING
Outdoor unit

Cutting copper tube
Piping works
Do not use contaminated or damaged copper tubing. Do not
remove plastic, rubber plugs and brass nuts from the valves,
fittings, tubings and coils until you are ready to connect
suction or liquid line into valves or fittings.
If any brazing work is required, ensure that the nitrogen gas
is passed through coil and joints while the brazing work is
being done. This will eliminate soot formation on the inside
walls of the copper tubings.
Cut the connection pipe with a pipe cutter.
Remove burrs from cut edges of the pipes with remover. Hold
the end of the pipe downwards to prevent metal chips from
entering the pipe.
Insert the flare nuts, mounted on the connection parts of both
the indoor unit and outdoor unit onto the copper pipes.
Flare the pipe with extra length above the flaring tool as shown
in the table.
The flared edge must be even and not cracked or scratched.
! Caution
An orifice is used as expansion device in WM301 cooling only unit. It is fixed in the liquid pipe in the indoor unit.
Piping connection to the units
Align the center of the piping and tighten the flare nut
sufficiently with fingers.
Finally, tighten the flare nut with the torque wrench
until the wrench clicks.

VACUUMING AND CHARGING
Purging the piping and the indoor unit
Except for the outdoor unit which is pre-charged with
refrigerant, the indoor unit and the refrigerant
connection pipes must be air-purged because the air
containing moisture that remains in the refrigerant cycle may
cause malfunction of the compressor.
Remove the caps from the valve and the service port.
Connect the centre of the charging gauge to the vacuum
pump.
Connect the charging gauge to the service port of the
3-way valve.
Start the vacuum pump. Evacuate for approximately 30
minutes. The evacuation time varies with different
vacuum pump capacity. Confirm that the charging gauge
needle has moved towards -76mmHg (0~76mmHg).
Caution
If the gauge needle does not move to 0~76mmHg, be
sure to check for gas leaks (using the refrigerant
detector) at flare type connection of the indoor and out-
door unit and repair the leak before proceeding to the
next step.
Close the valve of the changing gauge and stop the
vacuum pump.
On the outdoor unit, open the suction valve (3 way) and
liquid valve (2 way) (in anti-clockwise direction) with
4mm key for hexagon sacked screw.

R410A is a near azeotrope refrigerant blend of hydro fluorocarbon (HFC) which is environmental friendly. It has Zero
Ozone Depletion Potential (ODP=0) and this conforms to Montreal Protocol regulations. It has no flame propagation and
a low toxic refrigerant (rated as A1 by ARI). R410A is a mixture of R32 (50%) and R125 (50%).
POE oil is used as lubricant for R410A compressor, which is different from the mineral oil used for R22 compressor.
During installation or servicing, extra precaution must be taken not to expose the R410A system too long to moist air.
Residual POE oil in the piping and components can absorb moisture from the air.
Refrigerant R410A is more easily affected by dust of moisture compared with R22, make sure to temporarily cover the
ends of the tubing prior to installation.
No additional charge of compressor oil only is permitted.
No refrigerant other than R410A is permitted.
Tools designed specifically for R410A only.
i) Manifold gauge and charging hose
ii) Gas leak detector
iii) Refrigerant cylinder/charging cylinder
iv) Vacuum pump c/w adaptor
v) Flare tools
vi) Refrigerant recovery machine
!!
!!
! CAUTION
R410A must be charged as liquid. Usually R410A cylinder is equipped with a dip-pipe for liquid withdrawal.
If there is no dip-pipe, the cylinder should be inverted so as to withdraw liquid R410A from the valve.
Do not top-up when servicing leak, as this will reduce the unit performance. Vacuum the unit thoroughly and then
charge the unit with fresh R410A according to the amount recommended in the specification.
Do not touch the compressor or refrigerant piping when the chiller is running. If necessary wear protective gloves.
Additional charge
The refrigerant is pre-charged in the outdoor unit. If the
piping length is less than 7.62m (25 ft), then additional
charge after vacuuming is not necessary. If the piping length
is more than 7.62m (25 ft), then use the additional charge
valve as indicated in the table below.

AIR CONDITIONER UNIT OPERATION
Dry mode
When the air humidity is high, the unit can operate in dry
mode. Press <MODE> button and choose <DRY>.
If the room temperature is 2°C/35.6°F higher than the set
temperature, the air conditioner will operate under cooling
mode until it reaches within the 2°C/35.6°F range of
difference compared to the set temperature before it
converts to dry mode.
If the room temperature is within the 2°C/35.6°F range of
difference compared to the set temperature, it will
directly operate under dry mode.
The unit will operate at LOW speed under dry mode.
Heat mode (for heat pump unit only)
• When the unit is switched on from cold start or
defrosting cycle, the indoor fan will start to operate only
after the coil reaches the desired temperature.
When the set temperature is achieved, the indoor fan will
operate until the coil cannot provide anymore
additional heat.
Horizontal air flow control
For more effective air circulation, you can manually adjust
the air discharge grille to the left or right.
During cool mode operation and dry mode operation, do
not direct the air discharge louver downwards for too long.
If operating continues in this way, condensation may occur
on the louver, thus resulting in drippings.
Hot Keep (for heat pump only)
During compressor cut off, the indoor fan can be switched
to
(i) ON (default) or
(ii) OFF or
(iii) Interval on and off
by setting the slide switch shown in the diagram.
The switch is located at the front frame cover (next to
the ON/OFF switch).
NOTE : When the option is selected, the power supply of
the unit need to be reset in order to activate the
function.
Overheating protection (for heat pump unit only)
In case the internal and/or the external temperature is to
high, or the filter is dirty and clogged up, the refrigerant
may be overheated. The compressor will cut out when the
condensing temperature reaches 62°C/143.6°F.
Frost prevention
When the air filter is dirty, the evaporating temperature
will decrease and eventually cause frosting.
The LED light will blink to indicate that the filter is dirty.
If the evaporating temperature reaches -2°C/28.4°F, the
unit will trip and defrost.
Fan speed and rated cooling capacity
The rated cooling capacity is provided at the maximum
fan speed.
The cooling capacity is lower when the unit is operating at
MEDIUM and LOW fan speed.
