SYSTEM READINGS
NOTE :- The sight glass should only be used as an assistance to charging as the charge level showing in the glass will
vary according to different operating conditions. This is especially noticeable with the heat pump units where the system
may appear to be undercharged in the heating mode.
Evaporating temperature (suction gauge) should read approximately 2°C to 3°C with a room (return air temperature) of
approximately 22 °C
Condensing temperature (as read on the discharge gauge) should be in the region of 45 to 46 °C with an external
ambient temperature of 30°C (Condensing is normally 15 °C above ambient).
Running Checks
Once the system has been charged, the following running checks should be carried out:
Check the operation of the fan speed controller by observing an increase in fan speed if the outdoor coil is partially
blocked.
If the system is a heat pump option, check that the reversing valve switches over from cooling to heating and vice-versa.
NOTE: Head pressure control also operates in heating mode by slowing down the outdoor unit fan as the system
pressure rises. This can be checked by partially blocking the inlet grilles of the indoor unit and observing the outdoor unit
fan slowing down.
FINALLY AND MOST IMPORTANTLY
- Fill in the commissioning sheet and return a copy to the factory to ensure that
the warranty on the unit will be valid.
