Never supply power to the unit unless all wiring and tub-
ing are completed, reconnected and checked.
This system adopts highly dangerous electrical voltage.
Incorrect connection or inadequate grounding can cause
personal injury or death. Stick to the wiring diagram and
all the instructions when wiring.
Have the unit adequately grounded in accordance with
local electrical codes.

any other refrigerant. Never have air remain in the
refrigerant line as it may lead to rupture and other hazards.
Make sure no refrigerant gas is leaking out when install-
ation is completed.
Should there be refrigerant leakage, the density of refri-
gerant in the air shall in no way exceed its limited value,
or it may lead to explosion.
Keep your fingers and clothing away from any moving
parts.

jects are left in the unit.
Always ensure effective grounding for the unit.

installed at a telecommunication center or hospital.
Provide an electric leak breaker when it is installed in a
watery place.
Never wash the unit with water.
Should any emergency occur, stop the unit and discon-
nect the power immediately.
Handle unit transportation with care. The unit should not
be carried by only one person if it is more than 20kg.
Never touch the heat exchanger fins with bare hands.
Never touch the compressor or refrigerant piping without
wearing glove.
Do not have the unit operate without air filter.
