To ensure safety, please be mindful of the following precautions.
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.
Electric wires with insufficient capacity, wrong wire connections and insecure
wire terminals may cause electric shock or fire.

Outdoor Condensate Drainage (only for Heat pump unit)
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.
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.
During heating operation, the condensate and
defrosting water should be drained out reliably
through the drain hose. Install the outdoor dr-
ain connector in a Φ25 hole or Φ42 hole on the
base plate and attach the drain hose to the co-
nnector so that the waste water formed in the
outdoor unit can be drained out. The hole dia-
meter 25 or 42 must be plugged.
Whether to plug other holes will be determined
by the dealers to actual conditions.

Vacuum pumping
Leakage detection
1. Remove the valve caps on
the liquid valve and gas
valve and the nut of refri-
gerant charging vent.
2. Connect the charging hose
of piezometer to the refri-
gerant charging vent of gas
valve and then connect 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.
7. Reinstall the handle.

● 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
