5.4.1.8 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:
(1) The charge size is in accordance with the room size within which
the refrigerant containing parts are installed;
(2) The ventilation machinery and outlets are operating adequately
and are not obstructed;
(3) If an indirect refrigerating circuit is being used, the secondary circuit
shall be checked for the presence of refrigerant;
(4) Marking to the equipment continues to be visible and legible.
Markings and signs that are illegible shall be corrected;
(5) 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.
5.4.1.9 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
