Before Installation
• When installing or relocating the unit, be sure to keep the refrigerant circuit free
from air or substances other than the specied 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 unqualied 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 ammable 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 re.
