Information on Servicing

(Required for the units adopting R32 refrigerant only)
1. Checks to the area
Prior to beginning work on systems containing flammable refrigerants,
safety checks are necessary to ensure that the risk of ignition is
minimised. For repairs on the refrigerating system, the following
precautions shall be complied with prior to conducting work on the
system.
2. Work procedure
Works shall be undertaken in a controlled procedure so as to minimise
the risk of flammable gas or vapour being present while the work is being
performed.
3. General work area
All maintenance staff and other personnel working in the local area
shall be instructed on the nature of work to be carried out. Work in
confined spaces shall be avoided. The area around the work space shall
be sectioned off. Ensure that the conditions within the area have been
made safe by control of flammable material.
4. Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior
to and during work, to ensure the technician is aware of potentially
flammable atmospheres. Ensure that the leak detection equipment
being used is suitable for use with flammable refrigerants, i.e. no
sparking, that it is adequately sealed and intrinsically safe.
5. Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or
any associated parts, appropriate fire extinguishing equipment shall be
available. Have a dry power or CO
area.
6. No ignition sources
No person carrying out work on a refrigeration system, which involves
exposing any pipe work that contains or has contained flammable
refrigerant, shall use any sources of ignition in such a manner that it
may lead to the risk of fire or explosion. All possible ignition sources,
including cigarette smoking, should be kept sufficiently far away from
the site of installation. Repairing, removing and disposal, during which
flammable refrigerant can possibly be released to the surrounding
space shall be avoided. Prior to work taking place, the area around the
equipment is to be surveyed to make sure that there are no flammable
hazards or ignition risks. "NO SMOKING" signs shall be displayed.
7. Ventilated area
Ensure that the area is in the open or that it is adequately ventilated
before breaking into the system or conducting any hot work. A degree
of ventilation shall continue while the work is in process. The ventilation
should safely disperse any released refrigerant and preferably expel it
externally into the atmosphere.
8. Checks to the refrigeration equipment
Where electrical components are being changed, they shall be fit for the
purpose and for the correct specification. At all times the manufacturer's
maintenance and service guidelines shall be followed. If in doubt, consult
the manufacturer's technical department for assistance. The following
checks shall be applied to installations using flammable refrigerants:
• the charge size is in accordance with the room size where the refrig-
erant containing parts are installed;
• the ventilation machinery and outlets are operating adequately and
are not obstructed;
• if an indirect refrigerating circuit is being used, the secondary
circuits shall be checked for the presence of refrigerant; labelling on
the equipment continues to be visible and legible.
