Maintenance & Information
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;
•
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;
•
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
Repair 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. This shall be
reported to the owner of the equipment, so all parties are advised.
Initial 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.
CABLING
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or
any other adverse environmental effects. The check shall also consider the effects of aging or continual
vibration from sources such as compressors or fans.
REPAIR TO INTRINSICALLY SAFE COMPONENTS
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will
not exceed the permissible voltage and current permitted for the equipment in use.
Intrinsically safe components are the only types that can be worked on while live in the presence of a
flammable atmosphere. The test apparatus shall be at the correct rating. Replace components only
with parts specified by the manufacturer. Other parts may result in the ignition of refrigerant in the
atmosphere from a leak.
