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; 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.
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 there no
live electrical components and wiring are exposed while charging, recovering or purging the system; That there is
continuity of earth bonding.
7.Repairs to sealed components
1)During repairs to sealed components, all electrical supplies shall be disconnected from the equipment being
worked upon prior to any removal of sealed covers, etc. If it is absolutely
necessary to have an electrical supply to equipment during servicing, then a permanently operating form of leak
detection shall be located at the most critical point to warn of a potentially hazardous situation.
2)Particular attention shall be paid to the following to ensure that by working on electrical components, the casing is
not altered in such a way that the level of protection is a ected. This shall include damage to cables, excessive
number of connections, terminals not made to original specification, damage to seals, incorrect fitting of glands, etc.
Ensure that apparatus is mounted securely. Ensure that seals or sealing materials have not degraded such that they
no longer serve the purpose of preventing the ingress of flammable atmospheres. Replacement parts shall be in
accordance with the manufacturer's specifications.
NOTE: The use of silicon sealant may inhibit the e ectiveness of some types of leak detection equipment. Intrinsically
safe components do not have to be isolated prior to working on them.
