2 Maintenance instruction
2.2.6 No ignition sources
No person carrying out work in relation to a
refrigeration system which involves exposing
any pipe work 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
refrigerant can possibly be released to the
surrounding space. 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.
2.2.7 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 during the period
that the work is carried out. The ventilation
should safely disperse any released refrigerant
and preferably expel it externally into the
atmosphere.
2.2.8 Checks to the
refrigeration equipment
Where electrical components are being changed,
they shall be fit for the purpose and to 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 within which the refrigerant containing
parts are installed;
Air-conditioners / User's Manual
- the ventilation machinery and outlets are
operating adequately and are not obstructed;
- if an indirect refrigerating circuit is being used,
the secondary circuit shall be checked for the
presence of refrigerant;
- marking to the equipment continues to be
visible and legible. Markings and signs that are
illegible shall be corrected;
- refrigeration pipe or components are installed
in a position where they are unlikely to be
exposed to any substance which may corrode
refrigerant containing components, unless
the components are constructed of materials
which are inherently resistant to being
corroded or are suitably protected against
being so corroded.
2.2.9 Checks to electrical
devices
Repair and maintenance to electrical
components shall include initial safety checks
and component inspection procedures. If a
fault exists that could compromise safety, then
no electrical supply shall be connected to the
circuit until it is satisfactorily dealt with. If the
fault cannot be corrected immediately but it is
necessary to continue operation, an adequate
temporary solution shall be used. This shall be
reported to the owner of the equipment so all
parties are advised.
Initial safety checks shall include:
• that capacitors are discharged: this shall be
done in a safe manner to avoid possibility of
sparking;
• that no live electrical components and wiring
are exposed while charging, recovering or
purging the system;
• that there is continuity of earth bonding.
