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 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 mal-
function 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 refriger-
ant 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 connec-
tion 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.
