tem is not going to be used for a long time.

Evaluation of the performance

Operate unit for 15~20 minutes, then check the system refrigerant charge:
- Measure the pressure of the gas side service valve.
- Measure the temperature of the intake and discharge of air.
- Ensure the difference between the intake temperature and the discharge is more than 8°C.
- For reference, the gas side pressure of optimum condition is as below.(Cooling)

NOTICE
If the actual pressure are 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. The air conditioner is now ready for use.
