2. Instructions for repairing appliances containing
R290
Ensure that the outlet for the vacuum pump is
not close to any ignition sources and there is
ventilation available.

2.8 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 minimize 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.

2.9 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 reclaimed
refrigerant. It is essential that electrical power is
available before the task is commenced.
Local air-conditioner / User Manual
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.
