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.
Safety precautions for installing and relocating the unit

Leakage detection
1. With leakage detector
Check if there is leakage with leakage detector.
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.

Vacuum pumping
1. Remove the valve caps on the liquid
valve and gas valve and the nut of
refrigerant charging vent.
2. Connect the charging hose of piezometer to the refrigerant charging vent
of gas valve and then connect the
other charging hose to the
vacuum pump.
3. Open the piezometer completely
and operate for 10-15min to
check if the pressure of piezometer
remains in -0.1MPa.
4. Close the vacuum pump and maintain this
status for 1-2min to check if the pressure of
piezometer remains in -0.1MPa. If the
pressure decreases, there may be leakage.
5. Remove the piezometer, open the valve
6. Tighten the screw caps of valves and refrigerant charging vent.

● 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):
● Basing on the length of standard pipe, add refrigerant according to the
requirement as shown in the table. The additional refrigerant charging amount
