Commissioning
Refrigerant Charging The following information is based on a complete Airedale matched system and indicates
the approximate amount of refrigerant charge required. It is also assumed that the system
has been designed within operating parameters and to good refrigeration practice.
NOTE: 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.
NOTE:- The sight glass level must be checked in the COOLING MODE ONLY.
Adding Oil
The initial oil charge in the compressor is suitable for pipe runs up to 20m
(equivalent length).
For longer pipe runs add 26 g of oil for every ADDITIONAL 0.45 kg of refrigerant added
up to the maximum permissible equivalent pipe runs stated. Please consult Airedale for
further details.
