Safety instructions
Ensure that the outlet for the vacuum pump is not close to any
ignition sources and there is ventilation available.
8. Charging procedures
In addition to conventional charging procedures, the following
requirements shall be followed.
- Ensure that contamination of different refrigerants does not
occur when using charging equipment. Hoses or lines shall be as
short as possible to minimise the amount of refrigerant contained
in them.
- Cylinders shall be kept upright.
- Ensure that the refrigeration system is earthed prior to charging
the system with refrigerant.
- Label the system when charging is complete (if not already).
- Extreme care shall be taken not to overfill the refrigeration
system.
Prior to recharging the system it shall be pressure tested with OFN.
The system shall be leak tested on completion of charging but prior
to commissioning. A follow up leak test shall be carried out prior to
leaving the site.
9. Decommissioning
Before carrying out this procedure, it is essential that the technician
is completely familiar with the equipment and all its detail. It is
recommended good practice that all refrigerants are recovered
safely. Prior to the task being carried out, an oil and refrigerant
sample shall be taken in case analysis is required prior to re-use of
