- Replace the valve caps at both gas and liquid
side service valves and fasten them tight.
This completes air purging with a vacuum pump.
- Replace the pipe cover to the outdoor unit by
one screw
Now the air conditioner is ready for test run.
Settlement of outdoor unit
- Fix the outdoor unit with a bolt and
nut(ø10mm).
- When installing on the wall, roof or rooftop,
anchor the mounting base securely with a
nail or wire assuming the influence of wind
and earthquake.
- If the vibration of the unit is transmitted to the
pipe, secure the unit with an anti-vibration
rubber.

Evaluation of the performance

Operate the unit for 15~20 minutes, then
check the system refrigerant charge:
- Measure the pressure of the gas side service
valve.
- Measure the air temperature from inlet and
outlet of air conditiioner.
- Ensure the difference between the inlet and
outlet temperature is more than 8°C.
- For reference; the gas side pressure at opti-
mum condition is shown on table (cooling)
The air conditioner is now ready to use.

NOTE
If the actual pressure is higher than
shown, the system is most likely over-
charged, and charge should be removed.
If the actual pressure are lower than
shown, the system is most likely under-
charged, and charge should be added.
