Check according to the following requirement
after finishing installation.
Preparation of test operation
The client approves the air conditioner.
Specify the important notes for air conditioner to
the client.
Items to be checked
Possible malfunction
The unit may drop, shake or
emit noise.
Has the unit been
installed firmly?
Is water drained well?
It may cause condensation
and water dripping.
Have you done the refri-
gerant leakage test?
It may cause insufficient
cooling(heating) capacity.
It may cause malfunction or
damage the parts.
Is electric wiring and pip-
eline installed correctly?
It may cause malfunction or
damage the parts.
Is the unit grounded
securely?
Does the power cord fol-
low the specification?
It may cause malfunction or
damage the parts.
Is there any obstruction in
the air inlet and outlet?
Is heat insulation of pipe-
line sufficient?
It may cause malfunction or
damage the parts.
The gas valve and liquid
valve of connection pipe
are open completely?
The dust and sundries
caused during installation
are removed?
It may cause condensation
and water dripping.
It may cause electric leakage.
Is the inlet and outlet of
piping hole been covered?
2.
●
Is the voltage of power
supply according to the
voltage marked on the
nameplate?
It may cause insufficient
cooling(heating) capacity.

4. Close the vacuum pump and maintain this sta-
tus for 1-2min to check if the pressure of piezo-
meter remains in -0.1MPa. If the pressure de-
creases, there may be leakage.

air conditioner can’t start cooling.
With leakage detector:
Check if there is leakage with leakage detector.
With soap water:
If leakage detector is not available, please use
soap water for leakage detection. Apply soap
water at the suspected position and keep the
soap water for more than 3min. If there are air
bubbles coming out of this position, there's a
leakage.
