2-7. Checks to the refrigerating
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 actual refrigerant charge
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.
-Refrigerating 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.
• The owner of the equipment must be
informed or reported so all parties
are advised thereinafter.
