Charge Recovery (System Depressurization)

Charge Recovery (System Depressurization)

PAG And Mineral Oil, Fig. 1:

- When depressurizing a system do not vent refrigerant directly to atmosphere, always use Jaguar approved recovery equipment.
- Always decant compressor oil from a sealed container and do not leave oil exposed to the atmosphere for any reason other than to fill or empty a system. PAG oil is very hygroscopic and will rapidly become contaminated by atmospheric moisture.
- Plug pipes and units immediately after disconnection and only unplug immediately prior to connection. Do not leave the system open to atmosphere.
- It is not necessary to renew the receiver drier whenever the system has been 'opened' as previously advised - see note below. However, if a unit or part of the system is left open for more than five minutes, it may be advisable to renew the receiver drier. This guidance is based on U.K average humidity levels; therefore, locations with lower humidity will be less critical to moisture contamination of the unit. It must be stressed that there is not a 'safe' period for work to be carried out in: ALWAYS plug pipes and units immediately after disconnection and only remove plugs immediately prior to connection.


NOTE: The receiver/drier MUST be renewed if the compressor has failed or if it is suspected that debris may be in the system.


- If replacement parts are supplied without transit plugs and seals DO NOT use the parts. Return them to your supplier.
- Diagnostic equipment for pressure, mass and volume should be calibrated regularly and certified by a third party organization.
- Use extreme care when handling and securing aluminium fittings, always use a backing spanner and take special care when handling the evaporator.
- Use only the correct or recommended tools for the job and apply the manufacturer's torque specifications.
