after commissioning and
before the service technicians
hand over the installation.
Decommissioning
The technician that
decommissions the system must
be familiar with the system and
its parts. All the refrigerant must
be contained in a safe way.
Accumulated refrigerant and oil
may
need to be analysed before it is
reused.
For this reason take an oil
and refrigerant sample before
decommissioning.
There must be a power
supply in place before the
decommissioning is started.
1. Familiarise yourself with the
controls on the product and
how to use them.
2. Disconnect the power supply
to the system.
3. Before continuing with the
decommissioning, check
that:
– Mechanical equipment to
handle refrigerant
cylinders is available and
that all the necessary
personal protective
equipment is in place,
plus a person authorised
to monitor the
equipment and
refrigerant in line with
the applicable standards.
4. Pump as much refrigerant as
possible out of the system.
5. If it is not possible to pump
down to a vacuum, make
a branch pipe so that the
refrigerant can be removed
from the different parts of
the system.
6. Make sure to place the
refrigerant cylinders on
scale before pumping and
containing.
7. Start and use the equipment
in accordance with the
manufacturer’s instructions.
8. Do not overfill – the
refrigerant cylinders can
be filled up to 80% of their
volume.
9. Never exceed the maximum
permitted working pressure
for the refrigerant cylinders,
