2 Warnings (for using R290 refrigerant only)
•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.
9) 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.
