Evaluation of the performance

Operate all indoor units for 15~20 minutes, then			Intake temperature
check the system refrigerant charge:
1.Measure the pressure of one of the gas side			Discharge air
service valves.
2. Measure the temperature of the intake and
discharge of air.
3. Ensure the difference between the intake
temperature and the discharge is more than
8°C(14.4°F).			Discharge
4. For reference, the gas side pressure of			temperature
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 undercharged, and charge should be added.

NOTICE : For maximum product life and efficiency this unit has been designed, in the heating mode, to lock-out at outdoor temperatures below 26-29°F.

At outdoor temperatures below 26-29°F. another means of heating the conditioned space must be provided.

Important:
