1.1.9 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;
th
e
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.
Checks to electrical devices. R
epair
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. T
