When installing the unit, make sure that co-
nnection pipe is securely connected before
the compressor starts running.
If compressor starts running when stop valve
is open and connection pipe is not yet conne-
cted, air will be sucked in and cause pressure
rise or compressor rupture, resulting in injury.
1 minute.
When installing or relocating the unit, be s-
ure 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 pre-
ssure rise or compressor rupture, resulting
in injury.
When in
stalling 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
serious safety accident.

Safety precautions for installing and
relocating the unit
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
Use the specified types of wires for electrical
connections between the indoor and outdoor
units. Firmly clamp the wires so that their te-
rminals receive no external stresses.
Prohibit installing the unit at the place where
there may
be leaked corrosive gas or flamm-
able gas.
If there is leaked gas around the unit, it may
cause explosion and other accidents.
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 detachi-
ng the connection pipe.
If compressor starts running when stop valve
is open and
connection pipe is not yet conn-
ected, air will be sucked in and cause pressure
rise or compressor rupture, resulting in injury.
Do not use extension cords for electrical co-
nnections. If the electric wire is not long eno-
ugh, please contact a local service center au-
WARNING
thorized and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.
