expenses.
Trouble
Analysis
Does not run
• Please wait for 3 minutes and start again, protection device may be preventing
unit to work.
• Are the remote control batteries low?
• Is the plug not properly plugged?
No cooling or
heating air
•
•
•
•
Ineffective control
• Has there been a strong interference (from excessive static electricity discharge,
power supply voltage abnormality)? Note that operation will be abnormal, in this
case unplug from the power supply and re-plug after 2-3 seconds.
Does not operate
immediately
• 3 minute delay will occur when changing mode during operation.
Peculiar smell
• This smell may come from another source such as furniture, cigarette etc, which
is sucked in the unit and blown out with the air.
A sound of running
water
• Normal behaviour caused by the flow of refrigerant in the air conditioner.
• Defrosting sound in heating mode.
Cracking sound
• The sound may be generated by the expansion or contraction of the front panel
due to temperature changes.
Mist sprays from
the outlet
• Mist is present in the room with low temperature? Normal behaviour due to
cool air discharged from indoor unit during COOLING or DRY operation
mode.
Running indicator
flashes but indoor
fan stops.
• The unit is shifting from heating mode to defrost. The indicator will light off and
return to heating mode.
Water leakage
• Drainage pipe is connected inproperly, so water leakage occurs.
Is the air filter dirty?
Are the intakes and outlets of the air conditioner blocked?

2. Drill a Hole for Piping
• Decide the position of the hole for piping
according to the location of mounting plate.
• Drill a hole on the wall. The hole should slightly
be inclined downward toward outside.
• Install a sleeve through the wall hole to keep the
wall tidy and clean.

3. Indoor Unit Piping Installation
• Fit the piping (liquid and gas pipe) and cables
through the wall hole from outside or fit them
from inside after completing indoor piping and
cables connections so as to connect to outdoor unit.
• Decide whether saw off the plastic part in accordance with the piping direction (as shown below).

NOTE:
When fixing the pipe along directions 1, 2 or 4, saw the corresponding plastic part off the indoor unit base.
• After connecting the piping as required, install the drain hose. Then connect the power connecting
cable. After connecting, wrap the piping, cable and drain hose together with thermal insulating
materials.
NOTE: Do not connect to power supply during installation.

IMPORTANT:
Piping Joints Thermal Insulation:
Wrap the piping joints with thermal insulating materials and then wrap with a vinyl tape.

Thermal insulation
Thermal Insulation piping:
a. Place the drain hose under the piping.
b. Insulation material: polythene foam over 6mm in thickness.
NOTE:
• Drain hose is prepared by user.
• Cable should not be wrapped together with piping
and drain hose.
• Piping and drain hose must be wrapped thoroughly
in order to avoid dew formation.
• Drain hose should point downward for easy drain
flow. Do not twist the drain pipe, leave it sticking
out or waving around, do not immerse the end in
water. If an extension drain hose is connected to the
drain pipe, make sure to be thermally insulated
when passing it through the indoor unit.
• When the piping is directed to the right, piping
and drain hose should be thermally insulated and
fixed at the rear of the unit.

Piping Connection:
a. Connect indoor unit pipes with two wrenches. Pay
special attention to the torque allowed as shown
below to prevent the pipes, connectors and flare
nuts from being deformed and damaged.
b. At first fingers-tighten them, then use the wrenches.

4. Connecting the Cable
• Indoor Unit
1) Open the front panel, remove the covering plate by
loosening the screw.
2) Connect the power connecting cord to the indoor
unit by connecting the wires to the terminals on the
control board individually as follows.
3) Secure the power connecting cord on the control
board with cable clamp.
4) Refit the covering plate and tighten the screw.

• Outdoor Unit
1) Remove the access door from the unit by loosening
the screw. Connect the wires to the terminals on
the control board individually in accordance with
the indoor unit connection.
2) Secure the power connecting cord on the control
board with cable clamp.
3) Refit the access door in the original position and
tighten the screw.
4) Use a recognized circuit breaker for 24K model
between the power source and the unit. A
disconnecting device to adequately disconnect all
supply lines must be fitted.

CAUTION:
1. Make sure that the colour of wires and the terminal number of the outdoor unit are the same as those
of the indoor unit.
2. Use an individual power circuit specifically for the air conditioner. As for the wiring method, refer to the
circuit diagram on the appliance.
3. Check that the cable specification conforms to the table as follows.
4. Check the wires and make sure that they are all tightly fastened after cable connection. The cable
should be tighly fastened by cable clamp.
5. Be sure to install an earth leakage circuit breaker in a wet or moist area.

OUTDOOR UNIT INSTALLATION
1. Install Drain Port and Drain Hose
The condensate drains from the outdoor unit when
the unit operates in heating mode. In order not to
disturb your neighbours and protect the
environment, install a drain port and a drain hose to
direct the condensate water. Just install the drain
port on the chassis of the outdoor unit, then
connect a drain hose to the port as shown in the
figure on the right. (Drain hose is not included, it
Chassis
should be purchased by customer sparately)

2. Install and Fix Outdoor Unit
Fix with bolts and nuts tightly on a flat and strong
Drain hose
floor. If installed on the wall or roof, make sure to
(prepare by user)
fix the supporter well to prevent it from shaking due
to serious vibration or strong wind.
3. Outdoor Unit Piping Connection
• Remove the valve caps from the 2-way and 3-way valve.
• Connect the pipes to the 2-way and 3-way valves separately according to the required torque.
4. Outdoor Unit Cable Connection (see previous page)

AIR PURGING
Air containing moisture remaining in the refrigeration cycle may cause a malfunction on the compressor.
After connecting the indoor and outdoor units, evacuate air and moisture from refrigerant cycle using a
vacuum pump, as shown below.
Note: Because the system pressure is high and also to protect the environment, be sure not to discharge
the refrigerant to the air directly.

2. Unscrew and remove cap from service valve.
3. Connect vacuum pump flexible hose to the service valve.
4. Start vacuum pump for 10-15 minutes until it reaches an absolute vacuum of 10 mm Hg.
5. With vacuum pump still running close the low pressure knob on vacuum pump manifold. Then stop
vacuum pump.
6. Open 2-way valve 1/4 turn, then close it after 10 seconds. Check tightness of all joints using liquid soap
or an electronic leak detector.
7. Turn 2 and 3-way valves stem. Disconnect vacuum pump flexible hose.
8. Replace and tighten all valve caps.
