30. All the refrigerant must be recovered safely, also collect a sample of oil and
refrigerant if it is necessary to collect a sample of oil and refrigerant in case an
analysis is necessary before the reuse of the recovered refrigerant.
Before carrying out the procedure, electrically insulate the system and make
sure that:
• the mechanical movement equipment of the cylinders containing refrigerant
are available;
• all the personal protective equipment is used correctly;
• the recovery process is supervised, at any moment, by a competent person;
• the equipment and recovery cylinders are compliant with the standards.
Empty the system and, if that is not possible, use a collector in order to be able
to remove the refrigerant.
Before the recovery starts, make sure the cylinder is positioned on the scale
and start the recovery machine working according to the instructions.
31. DO NOT fill the cylinders excessively (the liquid must not be higher than 80%
of the volume).
DO NOT exceed, even temporarily, the maximum operating pressure of the
cylinder.
Once the process is complete, as previously described, make sure the equipment
and the cylinders are removed. Before switching on the appliance, check that
all the insulation valves are closed.
32. Recovered refrigerant must not be discharged in another refrigerating systems
unless it has been cleaned and checked.
0.5 - SPECIAL REQUIREMENTS FOR R32 GAS
The table 1a refers to the 8-10kW units. For 4-6kW units, a maximum length of the
pipes 30m is allowed and no evaluation of the minimum area is necessary
The table 1b refers to the 12-14-16kW units.
• The pipes must be protected against physical damage. The installation of the pipes
must be the minimum one.
• If the total charge of refrigerant in the system is <1,842 kg (namely if the pipes length
is ≤ 20m for 8-10kW units or ≤ 15m for 12-14-16kW units) there are no requirements of
minimum area to be evaluated.
If the charge of refrigerant exceeds 1,842 kg (namely if the pipes length is ≥ 20m for
8-10kW units or ≥ 15m for 12-14-16kW units) the minimum area request must be verified
as indicated by the diagrams corresponding to the chosen size.
