The Refrigerant
WARNING
To realize the function of the air conditioner unit, a special refrigerant circulates in
the system. The used refrigerant is the fluoride R32, which is specially cleaned.
The refrigerant is flammable and inodorous. Furthermore, it can leads to explosion
under certain conditions. But the flammability of the refrigerant is very low. It can
be ignited only by fire.
Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm
to the ozonosphere. The influence upon the greenhouse effect is also lower. R32
has got very good thermodynamic features which lead to a really high energy
efficiency. The units therefore need a less filling.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacture. Should repair be necessary, contact your
nea
rest authorized Service Centre. Any repairs carried out by unqualified
personnel may be dangerous. The appliance shall be stored in a room without
continuously
operating ignition sources. (for example: open flames, an operating
gas appliance
or an operating electric heater.) Do not pierce or burn.
Appliance shall be installed, operated and stored in a room with a floor area larger
than Xm .(Please refer to table "a" in section of " Safety Operation of Inflammable
Refrigerant" for Space X.)
Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s
instructions only. Be aware that refrigrants not contain odour. Read specialist’s
manual.

6. OPERATIONS AND PERFORMANCES
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
●The compressor can't restart for 3 minutes after it stops.
Anti-cold air (Cooling and heating models only)
●The unit is designed not to blow cold air on HEAT mode, when the indoor heat exchanger is in one of the following three
situations and the set temperature has not been reached.
A) When heating has just starting.
B) Defrosting.
C) Low temperature heating.
●The indoor or outdoor fan stop running when defrosting (Cooling and heating models only). Defrosting (Cooling and
heating models only)
●Frost may be generated on the outdoor unit during heat cycle when outdoor temperature is low and humidity is high
resulting in lower heating efficiency of the air conditioner.
●During this condition air conditioner will stop heating operation and start defrosting automatically.
●The time to defrost may vary from 4 to 10 minutes according to the outdoor temperature and the amount of frost build-up
on the outdoor unit.
2. A white mist coming out from the indoor unit
●A white mist may generate due to a large temperature difference between air inlet and air outlet on COOL mode in an
indoor environment that has a high relative humidity.
●A white mist may generate due to moisture generated from defrosting process when the air conditioner restarts in HEAT
mode operation after defrosting.
3. Low noise of the air conditioner
●You may hear a low hissing sound when the compressor is running or has just stopped running. This sound is the sound
of the refrigerant flowing or coming to a stop.
●You can also hear a low "squeak" sound when the compressor is running or has just stopped running. This is caused by
heat expansion and cold contraction of the plastic parts in the unit when the temperature is changing.
●A noise may be heard due to louver restoring to its original position when power is first turned on.
4. Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not been used for a long time or during first use of the unit.
5. A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated from building material, from furniture, or smoke.
6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and heating models only) mode.
When indoor temperature reaches the temperature setting on air conditioner, the compressor will stop automatically, and
the air conditioner turns to FAN only mode. The compressor will start again when the indoor temperature rises on COOL
mode or falls on HEAT mode (For cooling and heating models only) to the set point.
7. Dripping water may generate on the surface of the indoor unit when cooling in a high relatively humidity (relative
humidity higher than 80%).
Adjust the horizontal louver to the maximum air outlet position and select HIGH fan speed.
8. Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit during heating operation. When the
outdoor temperature falls, heat drawn in by the air conditioner decreases accordingly. At the same time, heat loading of the
air conditioner increases due to larger difference between indoor and outdoor temperature. If a comfortable temperature
can't be achieved by the air conditioner, we suggest you use a supplementary heating device.

9. Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power restores, the OPERATION indicator on the indoor unit starts
flashing. To restart the operation, push the button on the remote controller. For the unit with Auto-restart feature, when
the power restores, the unit restarts automatically with all the previous settings preserved by the memory function.

Fit the seal into the drain elbow, then insert the drain joint into the base pan hole of outdoor unit, rotate 90 to securely
assemble them. Connecting the drain joint with an extension drain hose (Locally purchased), in case of the water draining
off the outdoor unit during the heating mode.
Piping and wrapping
Bundle the tubing, connecting cable, and drain hose with tape securely.
●Because the condensed water from rear of the indoor unit is gathered in pending box and is piped out of room. Do not put
anything else in the box.
CAUTION
●Connect the indoor unit first, then the outdoor unit.
●Do not allow the piping to let out from the back of the indoor unit.
●Be careful not to let the drain hose slack.
●Heat insulated both of the auxiliary piping.
●Be sure that the drain hose is located at the lowest side of the bundle.
Locating at the upper side can cause drain pan to over flow inside the unit.
●Never intercross nor intertwist the power wire with any other wiring.
●Run the drain hose sloped downward to drain out the condensed water
smoothly.

Refrigerant piping connection
1. Flaring work
Main cause for refrigerant leakage is due to defect in the flaring work. Carry out
correct flaring work using the following procedure:
A: Cut the pipes and the cable.
1. Use the piping kit accessory or pipes purchased locally.
2. Measure the distance between the indoor and the outdoor unit.
3. Cut the pipes a little longer than the measured distance.
4. Cut the cable 1.5m longer than the pipe length.
B: Burr removal
1. Completely remove all burrs from the cut cross section of pipe/tube.
2. Put the end of the copper tube/pipe in a downward direction as you remove burrs
in order to avoid dropping burrs into the tubing.
C: Putting nut on
Remove flare nuts attached to indoor and outdoor unit, and then put them on pipe/tube having completed burr removal. (Not
possible to put them on after flaring work).
D: Flaring work
Firmly hold copper pipe in a die in the dimension shown in the table below.

Air purging
Air and moisture in the refrigerant system have undesirable effects as indicated
below:
●Pressure in the system rises.
●Operating current rises.
●Cooling or heating efficiency drops.
●Moisture in the refrigerant circuit may freeze and block capillary tubing.
●Water may lead to corrosion of parts in the refrigeration system.
Therefore, the indoor unit and tubing between the indoor and outdoor unit must be
leak tested and evacuated to remove any non-condensable and moisture from the
system.
Air purging with vacuum pump
●Preparation
Check that each tube (both liquid and gas side tubes) between the indoor and
outdoor units have been properly connected and all wiring for the test run has been
completed. Remove the service valve caps from both the gas and the liquid side on
the outdoor unit.
Note that both the liquid and the gas side service valves on the outdoor unit are
kept closed at this stage.
●Pipe length and refrigerant amount:
●When relocate the unit to another place, perform evacuation using vacuum
pump.
Make sure the refrigerant added into the air conditioner is liquid form in any case.
Caution in handling the packed valve
●Open the valve stem until it hits against the stopper. Do not try to open it further.
●Securely tighten the valve stem cap with a spanner or the like.
●Valve stem cap tightening torque (See Tightening torque table in previous page).
When Using the Vacuum Pump
(For method of using a manifold valve, refer to its operation manual.)
1. Completely tighten the flare nuts, A, B, C, D, connect the manifold valve charge
hose to a charge port of the low-pressure valve on the gas pipe side.
2. Connect the charge hose connection to the vacuum pump.
3. Fully open the handle Lo of the manifold valve.
4. Operate the vacuum pump to evacuate. After starting evacuation, slightly loose
the flare nut of the Lo valve on the gas pipe side and check that the air is entering
(Operation noise of the vacuum pump changes and a compound meter indicates
0 instead of minus)

5. After the evacuation is complete, fully close the handle Lo of the manifold valve
and stop the operation of the vacuum pump. Make evacuation for 15 minutes or more
and check that the compound meter indicates -76cmHg (1x105Pa).
6. Turn the stem of the packed valve B about 45° counter clockwise for 6-7 seconds
after the gas coming out, and then tighten the flare nut again. Make sure the
pressure display in the pressure indicator is a little higher than the atmosphere
pressure.
7. Remove the charge hose from the Low pressure charge hose.
8. Fully open the packed valve stems B and A.
9. Securely tighten the cap of the packed valve.
