The Refrigerant
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.

Warning
When installing or relocating the unit, be sure to keep the refrigerant circuit free from air or substances other than the specified refrigerant.
Any presence of air or other foreign substance in the refrigerant circuit will cause system pressure rise or compressor rupture, resulting in injury.
When installing or moving this unit, do not charge the refrigerant which is not comply with that on the nameplate or unqualified refrigerant.
Otherwise, it may cause abnormal operation, wrong action, mechanical malfunction or even series safety accident.
When refrigerant needs to be recovered during relocating or repairing the unit, be sure that the unit is running in cooling mode.Then, fully close the valve at high pressure side (liquid valve).About 30-40 seconds later, fully close the valve at low pressure side (gas valve), immediately stop the unit and disconnect power. Please note that the time for refrigerant recovery should not exceed 1 minute.
If refrigerant recovery takes too much time, air may be sucked in and cause pressure rise or compressor rupture, resulting in injury.
During refrigerant recovery, make sure that liquid valve and gas valve are fully closed and power is disconnected before detaching the connection pipe.
If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.
When installing the unit, make sure that connection pipe is securely connected before the compressor starts running.
If compressor starts running when stop valve is open and connection pipe is not yet connected, air will be sucked in and cause pressure rise or compressor rupture, resulting in injury.
Prohibit installing the unit at the place where there may be leaked corrosive gas or flammable gas.
If there leaked gas around the unit, it may cause explosion and other accidents.
Do not use extension cords for electrical connections. If the electric wire is not long enough, please contact a local service center authorized and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.
Use the specified types of wires for electrical connections between the indoor and outdoor units. Firmly clamp the wires so that their terminals receive no external stresses.

Installation of outdoor unit
2. Fix the power connection wire and signal control wire with wire clip (only for
cooling and heating unit).
Note:
● Never cut the power connection wire to prolong or shorten the distance.
Step six: neaten the pipes
1. The pipes should be placed along the wall,
bent reasonably and hidden possibly. Min. semidiameter of bending the pipe is 10cm.
2. If the outdoor unit is higher than the wall
hole, you must set a U-shaped curve in the pipe before pipe goes into the room, in order to prevent rain from getting into the room.
Note:
The through-wal height of drain hose shouldn't be higher than the outlet pipe hole of indoor unit.
the drain hose can't raise
upwards.
● Slant the drain hose slightly dow-
nwards. The drain hose can't be

Vacuum pumping
Use vacuum pump
1. Remove the valve caps on the liquid valve and gas valve and the nut of refri-
gerant charging vent.
2. Connect the charging ho-
se of piezometer to the refrigerant charging vent of gas valve and then co­ nnect the other charging hose to the vacuum pump.
3. Open the piezometer com-
pletely and operate for 10-15min to check if the pressure of piezometer re­ mains in -0.1MPa.
4. Close the vacuum pump and maintain this status for 1-2min to check if the pres-
sure of piezometer remains in -0.1MPa. If the pressure decreases, there may be leakage.
5. Remove the piezometer, open the valve core of liquid valve and gas valve completely with inner hexagon spanner.
6. Tighten the screw caps of valves and refrigerant charging vent.

Leakage detection
1. With leakage detector: Check if there is leakage with leakage detector.
2. With soap water: If leakage detector is not available, please use soap water for leakage detection.
Apply soap water at the suspected position and keep the soap water for more
than 3min. If there are air bubbles coming out of this position, there's a leakage.

Test operation
1. Preparation of test operation
The client approves the air conditioner.
● Specify the important notes for air conditioner to the client.
2. Method of test operation
● Put through the power, press ON/OFF button on the remote controller to start
operation.
● Press MODE button to select AUTO, COOL, DRY, FAN and HEAT to check
whether the operation is normal or not.
● If the ambient temperature is lower than 16℃, the air conditioner can’t
start cooling.

Configuration of connection pipe
1. Standard length of connection pipe
● 5m7.5m8m
2. Min length of connection pipe For the unit with standard connection pipe of 5m, there is no limitation for the min length of connection pipe. For the unit with standard connection pipe of
7.5m and 8m, the min length of connection pipe is 3m.
3. Max length of connection pipe

4. The calculation method of additional refrigerant oil and refrigerant charging amount
after prolonging connection pipe
After the length of connection pipe is prolonged for 10m at the basis of standard length, you should add 5ml of refrigerant oil for each additional 5m of connection
pipe. The calculation method of additional refrigerant charging amount (on the basis
of liquid pipe):
(1) Additional refrigerant charging amount= prolonged length of liquid pipe × additional
refrigerant charging amount per meter
Basing on the length of standard pipe, add refrigerant according to the
(2)
requirement as shown in the table. The additional refrigerant charging amount
per meter is different according to the diameter of liquid pipe. See Sheet 2.
