REQUIREMENTS FOR OPERATION
Requirements for Operation, Service and Installation of Appliances Using
Flammable Refrigerants
Information on servicing (cont.)
– No person carrying out work in relation to a REFRIGERATING 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.
– 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.
– 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:
• marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be
corrected;
• refrigerating 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.
– 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.
Repairs to sealed components, intrinsically safe components
– Sealed electrical components shall be replaced.
– Intrinsically safe components must be replaced.
– Replace components only with parts specified by the manufacturer. Other parts may result in the ignition of
refrigerant in the atmosphere from a leak.
Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other
adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from
sources such as compressors or fans.
