Installation prepare
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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
