presence of refrigerant.
Equipment marking remains visible and legible. Markings and symbols that are
illegible should be corrected.
•
The components or refrigerant piping are installed in a location where they are not
susceptible to exposure to any substance that may corrode the refrigerant containing
components, unless the components are constructed of materials that are inherently
corrosion resistant or are adequately protected against corrosion.
1.9. Verification of electrical devices
Repair and maintenance of electrical components should include initial safety checks
and component-inspection procedures. If there is a fault that may compromise safety,
then no power supply should be connected to the circuit until the fault is satisfactorily
dealt with. If the fault cannot be corrected immediately, but continued operation is
necessary, a suitable temporary solution must be used. This should be reported to the
owner of the equipment so as to inform all parties.
During initial safety checks, make sure that capacitors are unloaded–this must be
done in a safe manner to avoid sparks; that no live wiring or electrical components
are exposed while loading, recovering, or purging the system; that there is continuity
in the earth connection.
2. Repair of sealed components
•
During the repair of sealed components, all power supplies should be disconnected
from the equipment being worked on prior to any removal of sealed covers, etc. If it
is absolutely necessary to have a power supply to the equipment during service, then
a permanently operating form of leak detection should be placed at the most critical
point to warn of a potentially hazardous situation.
Particular attention must be paid to the following to ensure that, when working on
electrical components, the housing is not altered in such a way as to affect safety.
This must include damage to cords, an excessive number of connections, terminals
not conforming to the initial specification, damage to seals, incorrect fitting of the
stuffing box, etc.
Ensure that the instrumentation is securely mounted.
Ensure that seals or sealing materials have not degraded until no longer being useful
