contaminated. The hoses should be as short as possible to minimize the
quantity of the refrigerant contained therein.
-
The cylinders must be kept upright.
Ensure that the cooling system is grounded before filling the system
-
with refrigerant.
-
Label the system after filling it with refrigerant (if it is not already
labelled).
-
Do not overload the cooling system.
Before refilling the system, it must be tested with OFN. The system must be
checked for leakage when the filling procedure is completed but before the unit
is placed in service. After the filling procedure, perform a leakage detection test.
16) Decommissioning
Before performing this procedure, it is essential that the technician is completely
familiar with the equipment and with all its components. It is recommended that
all refrigerants are safely recovered. Before performing this procedure, a sample
of oil and refrigerant is taken if an analysis is required before re-using the
regenerated refrigerant. It is essential that the power supply is available before
the procedure begins.
a.
Familiarize yourself with the equipment and with its operation.
b.
Insulate the system from the electrical point of view.
c.
Before proceeding, make sure that:
d.
Mechanical handling equipment is available if it is necessary for the
handling of coolant cylinders;
e.
All individual protection equipment are available and correctly used;
f.
the recovery process is permanently supervised by a qualified
person;
g.
The recovery equipment and cylinders are in accordance with the
appropriate standards.
h.
If possible, drain the cooling system.
i.
If aspiration is not possible, use a collector so that the refrigerant can
be removed from different parts of the system.
j.
Ensure that the cylinder is in upright position before recovery.
k.
Start the recovery machine and use it in accordance with the
instructions of the manufacturer.
l.
Do not fill the cylinders. (Must not exceed 80% of the quantity of
liquid).
m.
Do not exceed the maximum working pressure of the cylinder, even
temporarily.
n.
When the cylinders have been correctly loaded and the process has
been completed, make sure that the cylinders and the equipment are
quickly removed from the working area and that all the insulation
valves of the equipment are closed.
