Safety precautions for installing and relocating the unit

To ensure safety, please be mindful of the following precautions.

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 the system pressure to rise or the compressor to rupture, resulting in injury.
When installing or moving this unit, do not charge the refrigerant which does not comply with that on the nameplate or unqualified refrigerant. Otherwise, it may cause abnormal operation, wrong action, mechanical malfunction, or even a series of safety accidents.
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 the high-pressure side (liquid valve). About 30-40 seconds later, fully close the valve at the 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 the liquid valve and gas valve is fully closed and power is disconnected before detaching the connection pipe. If the compressor starts running when the stop valve is open and the 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 the connection pipe is securely connected before the compressor starts running.
If the compressor starts running when the stop valve is open and the 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 a place where there may be leaked corrosive gas or flammable gas.
If there is leaked gas around the unit, it may cause explosions 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.
