Safety precautions for installing and relocating the unit
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.

2. Fasten the power supply cord and the connection cord to the retaining plate using
the lock nut.(open the knock out holes if necessary)
3. Connect the power supply cord and the connection cord to terminal.
Fasten the power supply cord and connection cord with cord clamp.

5. Install the handle.
The screws are packed with the terminal board.
Note:If the connection wire between indoor and outdoor is multi-core cable, the
installation distance between the indoor and outdoor units is more than 20 meters,
it’s required to connect the wiring
according to the following diagram,
and ensure that the conductors
connected to the “2” and “3”position of
the wiring board are diagonally positioned
in the cable.Otherwise,the machine may
call communication error to lead the
machine can’t work.

Installation of outdoor unit
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-wall
shouldn't be higher than the outlet
pipe hole of indoor unit.
● The water outlet can't be placed
in water in order to drain smoothly.

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 hose
of manifold to the refri-
gerant charging vent of gas
valve and then connect the
other charging hose to the
vacuum pump.
3. Open the manifold completely and operate
for 15min to check if the pressure of manifold
remains in -0.1MPa.

4. Close the vacuum pump and maintain this
status for 2min to check if the pressure of the
close
open
manifold remainsin -0.1MPa. If the pressure
decreases, there may be leakage.
5. Remove the manifold, 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.
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
start cooling.

4. The additional refrigerant oil and refrigerant charging required 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):
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
requirement as shown in the table. The additional refrigerant charging amount
per meter is different according to the diameter of liquid pipe. See the
following sheet.
