If it is not possible to pump to vacuum,

manufacture a branch, so that the refri-
gerant can be retrieved from different
parts of the system.
Check that the refrigerant container is

on the scales before starting to collect.
Start the collection device and collect

according to the manufacturer's instruc-
tions.
Do not overfill the containers (max. 80

Do not exceed the containers' maximum

permitted working pressure – not even
temporarily.
When the containers have been filled

correctly and the process is complete,
close all shut-off valves in the equip-
ment and remove and containers and
equipment from the installation immedi-
ately.
The collected refrigerant must not be
11.
filled in any other system before being
cleaned and checked.
Marking
The equipment must be marked stating that
it has been taken out of operation and
drained of refrigerant. The marking must
be dated and signed. Check that the
equipment is marked indicating that it
contains combustible refrigerant.
Collection
Best practice prescribes that all refrigerant
is collected safely when the refrigerant is
drained from a system, either for servicing
or for decommissioning.
The refrigerant must only be collected in
suitable refrigerant containers. Ensure that
the required number of containers, which
can hold the entire volume of the system,
are available. All containers that are to be
used must be intended for the collection of
the refrigerant and marked for this refriger-
26
ant (specifically designed for the collection
of refrigerant). The containers have to be
equipped with correctly functioning pres-
sure relief valves and shut-off valves.
Empty collection containers must be
drained and, if possible, chilled before col-
lection.
The collection equipment must function
correctly and instructions for the equip-
ment must be to hand. The equipment must
be suitable for the collection of combustible
refrigerant.
Fully functioning and calibrated scales must
also be to hand.
Hoses must be in good condition and be
equipped with leak-proof quick couplings.
Before using the collecting machine, check
that it is working correctly and has been
properly maintained. Associated electrical
components must be sealed, to prevent ig-
nition if any refrigerant should leak out.
Contact the manufacturer if you are in any
doubt.
Return the collected refrigerant to the refri-
gerant supplier in the correct collection
container and with the relevant Waste
Transfer Note. Do not mix refrigerants in
collection devices or containers.
If compressors/compressor oil are/is to be
removed ensure that the affected device
is drained to an acceptable level to ensure
that no combustible refrigerant remains in
the lubricant. Compressors must be drained
before being returned to the supplier. Only
electrical heating of the compressor hous-
ing may be used to quicken draining. Drain
oil from the system in a safe manner.
MISCELLANEOUS
Maximum amount of refrigerant: See
Technical Specifications in the Installer
Manual.
Everyone who works with or opens a refri-
•
gerant circuit must have a current, valid
certificate from an accredited industry
issuing body, which states that, according
