Information on Servicing
Prior to recharging the system, it shall be pressure-tested with the appropriate
purging gas. 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.
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 reclaimed refrigerant. It is essential that
electrical power is available before the task is commenced.
Equipment shall be labelled stating that it has been de-commissioned and emptied of
refrigerant. The label shall be dated and signed. For appliances containing
( a ) Become familiar with the equipment and its operation.
( b ) Isolate system electrically.
( c ) Before attempting the procedure, ensure that:
( d ) Pump down refrigerant system, if possible.
( e ) If a vacuum is not possible, make a manifold so that refrigerant can be
removed from various parts of the system.
( f ) Make sure that cylinder is situated on the scales before recovery takes place.
( g ) Start the recovery machine and operate in accordance with manufacturer’s
instructions.
( h ) Do not overfill cylinders. (No more than 80 % volume liquid charge).
( i ) Do not exceed the maximum working pressure of the cylinder, even temporarily.
( j ) When the cylinders have been filled correctly and the process completed,
make sure that the cylinders and the equipment are removed from site promptly
and all isolation valves on the equipment are closed off.
( k ) Recovered refrigerant shall not be charged into another refrigeration system
unless it has been cleaned and checked.
 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.
