The cylinders must be complete of a pressure relief valve and of and of the
corresponding closure valve in good conditions. Empty cylinders are evacuated
and, if possible, cooled down before recovery.
14b
Equipment for recovery must be within the range of the technician, in good
.
conditions, with a series of instructions and must be suitable for recovery of all
the refrigerants (even flammable ones).
A series of calibrates scales must be available and in good conditions.
Check that the pipes are in good conditions and complete of disconnection
joints without losses.
14c
Before using the machine for recovery, check that it is in good operating
.
conditions, that it has been adequately maintained and that all the associated
electric components are sealed to prevent switching-in in case of release of
refrigerant. In case of doubt, please contact the manufacturer.
15. Collected refrigerant must be returned to the fluid supplier in the appropriate
collection cylinder, compiling the corresponding Handover Note of Scraps.
DO NOT mix the refrigerants in the collection units and, in particular, in the
cylinders.
16. Make sure that contamination between different refrigerants does not occur
when a reloading equipment is used.
The flexible pipes or ducts must be as short as possible to reduce the quantity
of refrigerant inside them to a minimum.
17. Do not drill nor burn the unit.
18. The replaced electric components MUST be suitable and correspond to the
appliance specifications.
Every maintenance operation MUST be carried out as described in this manual.
Contact the manufacturer in case of doubt.
19. Apply the following checks:
• The size of the room inside which are located the parts containing the
refrigerant, are in accordance with the current quantity of charge of the
refrigerant (see par. 0.5);
• The ventilation device works correctly and the outlets are not clogged;
• The markings on the machine must always be visible and readable, correct
them if not;
• The pipelines ore the components containing refrigerant MUST be installed
in a place where no substance may corrode them, unless the components are
built with materials intrinsically resistant against corrosion or are suitably
protected against this risk.
20. The refrigerating gases are odourless.
21. For disposal and marking (through signs) of the appliance containing refrigerant
gas, please refer to the local regulations.
22. To store the appliance:
The packaging for storage must be resistant in order to avoid that the appliance
may take damage and to avoid the possible leakage of refrigerant gas.
23. Recovered refrigerant must not be discharged in another refrigerating system
unless it has been cleaned and checked.
