2-7. Checks to the refrigeration
equipment
• Where electrical components are
being changed, they shall be fi t
for the purpose and to the correct
specifi cation.
• 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
fl ammable 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.

-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
properly protected against being
so corroded.
2-8. Checks to electrical devices
• Repair and maintenance to
electrical components shall include
initial safety checks and component
inspection procedures.
• Initial safety checks shall include
but not limit to:-
-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.
• At all times the manufacturer's
maintenance and service guidelines
shall be followed.
• If in doubt consult the
manufacturer's technical
department for assistance.
• 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.
