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,

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
WARNING
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 a place where
there may be leaked corrosive gas or flamm-
able gas.
If there is leaked gas around the unit, it may
cause an explosi
o
n an d
o
ther 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.
