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
his
shall
be
reported
to
the
owner
of
the
equipment
so
all
parties
are
advised.
i
nitial
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.
Repairs to sealed components.
D
uring 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
