Safety Precautions for Installing and Relocating the Unit:
To ensure safety, please be mindful of the following precautions.
1. 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.
2. 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.
3. 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.
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 star ts 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 star ts 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 ammable 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 re.
8. Use the specified t ypes 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 insufcient capacity, wrong wire connections
and insecure wire terminals may cause electric shock or re.
