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.

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.
a) Become familiar with the equipment and its operation.
b) isolate system electrically.
c) Before attempting the procedure ensure that:
• Mechanical handling equipment is available, if required, for handling
refrigerant cylinders;
• All personal protective equipment is available and being used
correctly;
• The recovery process is supervised at all times by a competent person;
• Recovery equipment and cylinders conform to the appropriate standards.
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.
