indoor temperature is
reached to set temp-
erature?

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.

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-

in injury.
When in

Safety precautions for installing and
relocating the unit
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.
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.
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.
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-
thorized and ask for a proper electric wire.
Poor connections may lead to electric shock or fire.
