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-ss
ure rise or comp
ressor
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 malfunction or even
serious 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.

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 conne-
cted, 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 an 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.
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.
Electric wires with insufficient capacity, wrong
wire connections and insecure wire terminals
may cause electric shock or fire.
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.
