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 ma-
nufacturer'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 refri-
gerant;
- Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be co-
rrected;
- Refrigeration pipe or components are installed in a position where they are unlikely to be exposed to any subs-
tance 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 adequa tetemporary solution shall be used. This shall be reported to the owner of the equipment
so all parties are advised.
Initial safety checks shall include:
- Those 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.
Releasing refrigerant into atmosphere is strictly forbidden!
