liquid side valve stem by turning it to count-
er-clockwise direction with service valve
wrench.

ing to counter-clockwise with service valve
wrench.
- Remove slowly the charge hose connected
to the gas side service port (to release the
pressure).
- Replace back the flare nut and its bonnet on
the gas side service port. Fasten the flare nut
with adjustable wrench to prevent any leak-

Test running
PRECAUTIONS IN TEST RUN
- The initial power supply must provide at least
90% of the rated voltage.
Otherwise, the air conditioner should not be
operated.
CHECK THE FOLLOWING ITEMS WHEN
INSTALLATION IS COMPLETED
- After completing work, be sure to measure
and record trial run properties, and store
measured data, etc.
- Measuring items are room temperature, out-
side temperature, suction temperature, blow
out temperature, wind velocity, wind vol-
ume, voltage, current, presence of abnormal
vibration and noise, operating pressure, pip-
ing temperature, compressive pressure.
- As to the structure and appearance, check
following items.
* Is the circulation of air adequate?
* Is the draining smooth?
* Is the heat insulation complete
(refrigerant and drain piping)?
* Is there any leakage of refrigerant?
* Is the remote controller switch operated?
* Is there any faulty wiring?
* Are not terminal screws loosened?

CAUTION
• For test run, carry out the cooling opera-
tion firstly even during heating season.
If heating operation is carried out firstly,
it leads to the trouble of compressor.
Then attention must be paid.
• Carry out the test run more than 5 min-
utes without fail.
