Safety precautions for installing and
relocating the unit
To ensure safety, please be mindful of the
following precautions.
WARNING
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
series safety accident.
■
When refrigerant needs to be recovered
during relocating or repairing the unit,be
Space to the obstruction
At least 50cm
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.
■
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.
■
When installing the unit, make sure that co-
nnection pipe is securely connected before
the compressor starts running.
Drainage pipe
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 leaked gas around the unit, it may ca-
use 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.
