recovered refrigerant and labelled for that refrig-
erant (i.e. special cylinders for the recovery of
refrigerant). Cylinders shall be complete with
pressure relief valve and associated shut-off
valves in good working order. Empty recovery
cylinders are evacuated and, if possible, cooled
before recovery occurs.
- The recovery equipment shall be in good work-
ing order with a set of instructions concerning
the equipment that is at hand and shall be
suitable for the recovery of flammable refriger-
ants. In addition, a set of calibrated weighing
scales shall be available and in good working
order. Hoses shall be complete with leak-free
disconnect couplings and in good condition. Be-
fore using the recovery machine, check that it is
in satisfactory working order, has been properly
maintained and that any associated electrical
components are sealed to prevent ignition in
the event of a refrigerant release. Consult man-
ufacturer if in doubt.
- The recovered refrigerant shall be returned to
the refrigerant supplier in the correct recovery
cylinder, and the relevant Waste Transfer Note
arranged. Do not mix refrigerants in recovery
units and especially not in cylinders. If compres-
sors or compressor oils are to be removed,
ensure that they have been evacuated to an
acceptable level to make certain that flammable
refrigerant does not remain within the lubricant.
The evacuation process shall be carried out pri-
or to returning the compressor to the suppliers.
Only electric heating to the compressor body
shall be employed to accelerate this process.
When oil is drained from a system, it shall be
carried out safely.
COMPETENCE OF SERVICE
PERSONNEL
GENERAL
- Special training additional to usual refrigerat-
ing equipment repair procedures is required
when equipment with flammable refrigerants is
affected.
- In many countries, this training is carried out by
national training organisations that are accred-
ited to teach the relevant national competency
standards that may be set in legislation.
- The achieved competence should be docu-
mented by a certificate.
TRAINING
- The training should include the substance of
the following:
- Information about the explosion potential of
flammable refrigerants to show that flammables
may be dangerous when handled without care.
- Information about potential ignition sources,
especially those that are not obvious, such
as lighters, light switches, vacuum cleaners,
electric heaters.
- Information about the different safety concepts:
- Unventilated – (see Clause GG.2) Safety of the
appliance does not depend on ventilation of
- the housing. Switching off the appliance or
opening of the housing has no significant effect
on the safety. Nevertheless, it is possible that
leaking refrigerant may accumulate inside the
enclosure and flammable atmosphere will be
released when the enclosure is opened.
- Ventilated enclosure – (see Clause GG.4) Safe-
ty of the appliance depends on ventilation of
- the housing. Switching off the appliance or
opening of the enclosure has a significant effect
- on the safety. Care should be taken to ensure a
sufficient ventilation before.
- Ventilated room – (see Clause GG.5) Safety of
the appliance depends on the ventilation of
- the room. Switching off the appliance or open-
ing of the housing has no significant effect on
- the safety. The ventilation of the room shall not
be switched off during repair procedures.
- Information about the concept of sealed compo-
nents and sealed enclosures according to IEC
60079-15:2010.
- Information about the correct working proce-
dures:
COMMISSIONING
- Ensure that the floor area is sufficient for the
refrigerant charge or that the ventilation duct is
assembled in a correct manner.
- Connect the pipes and carry out a leak test
before charging with refrigerant.
- Check safety equipment before putting into
service.
MAINTENANCE
- Portable equipment shall be repaired outside or
in a workshop specially equipped for servicing
units with flammable refrigerants.
