Safety precautions
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.
