Safety Precautions for the installer
• 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.
