REFRIGERANT
CHARGING
It is important that the system is charged with the correct amount of refrigerant.
Remember, a seriously over or undercharged system may lead to major
component failure.
The final refrigerant charge level should be set by the design evaporating and condensing
pressures, together with a full or nearly full sight glass.
The suction and discharge pressures should be constantly monitored whilst charging is
in progress.
To calculate the system refrigeration charge, please refer to the indoor unit data.
