The adjacent components must always be screened with non-flammable material and if the operation is to be carried out near any part of the
lubrication system, or close to a component which may contain oil, the system must first be thoroughly purged, preferably by steam cleaning.
Never use a light source with an open flame to inspect any part of the machine.
For every unit establish a suitable time schedule for cleaning operations.
ATTENTION
If replacement parts are needed use only original spares.
Avoid to damage the safety valves and other pressure relief devices.
All guards must be reinstated after carrying out repair or maintenance work.
ATTENTION
Check the direction of rotation of electric motors (the pump if installed) when starting up the unit initially and after any work on the
electrical connections or switch gear.
Do not use flammable liquid to clean any component during operation. If chlorinated hydrocarbon non-flammable fluids are used for cleaning,
safety precautions must be taken against any toxic vapours which may be released.
ATTENTION
Before removing any panels or dismantling any part of the unit, carry out the following operations:
- Isolate the unit from the main electrical power supply by disconnecting the cable from the electrical power source.
- Lock the isolator in the “OFF” position with a lock.
- Attach a warning label to the main isolator switch conveying: “WORK IN PROGRESS - DON NOT APPLY VOLTAGE”.
- Do not switch on electrical power or attempt to start the unit if a warning label is attached.
Coloured tracers can be used in service-maintenance operations.
Inspect all refrigerant circuit joints including connectors, flanges, and more generally all critical points (open joints) in order to prevent possible
leakage of refrigerant gas.
