manual.
Never supply power to the unit unless all wiring and tubing
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.
Have all wiring connected tightly. Loose connection may
lead to overheating and a possible fire hazard.

Apply specified refrigerant only. Never have it mixed with
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
installation is completed.
Should there be refrigerant leakage, the density of
refrigerant in the air shall in no way exceed its limited
value
, or it may lead to explosion
.

Make a proper provision against noise when the unit is
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.
Handle unit transportation with care. The unit should not be
carried by only one person if it is more than 20kg.
