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: 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.
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 operation, an adequate temporary solution shall be used.
This shall be reported to the owner of the equipment so all parties
are advised.
