Topping up the refrigerant
Filling with refrigerant
In addition to the usual filling procedure, the following
requirements must be satisfied:
- make sure that the filling valve is not used for different
refrigerants. The pipes should be as short as possible to
minimise the amount of refrigerant contained.
- the refrigerant bottles must remain in a vertical position.
14
- make sure the refrigerant circuit is earthed before filling it.
- the appliance may be marked (if not already marked) when
the filling process is complete.
- take special care not to overfill the appliance.
Before the appliance is filled, a pressure test with nitrogen
must be carried out. The leak test can be performed on the
filled appliance, but it must be done before commissioning. A
final leak test must be performed before leaving the facility.
Deactivation
To deactivate it, it is especially important that the technician
is familiar with all details of drain equipment. We recommend
that first of all the refrigerant is recovered. Before draining,
take samples of the oil and refrigerant if the refrigerant needs
to be treated. The important factor is that there is a power
supply available where the work is to be carried out.
a) Familiarise yourself with the appliance and how it operates.
b) The system must not be powered.
c) Before starting the draining, ensure that:
- equipment is available (where required) to transport the
bottles of refrigerant;
- PPE are available and that they are used correctly;
- the suction process is constantly monitored by a qualified
person;
15
- the draining station and refrigerant bottles comply with the
relevant guidelines.
d) Carry out a pumping cycle, if possible.
e) If a vacuum cannot be created, suck with a manifold hose
so that the refrigerant can be removed from all parts of the
system.
f) Make sure that the refrigerant bottle is on the scale before
starting the suction.
g) Turn on the draining appliance and follow the manufacturer's
instructions.
h) Make sure that the recycling bottles are not overfilled (never
more than 80% of their capacity).
i) Never exceed the permissible operating overpressure of the
recycling bottle, even for a short period.
