Use only the refrigerant specified on the data plate of the unit.
Make sure that all instructions concerning operation and maintenance are strictly followed and that the complete unit, with all
accessories and safety devices, is kept in good working order. The accuracy of pressure and temperature gauges must be
regularly checked. If values are discovered that exceed the permissible tolerances, the gauges must be replaced.
Do not perform welding procedures or other operations that can produce heat in the vicinity of elements containing oil
or flammable liquids. Systems which may contain oil or flammable liquids must be completely purged and cleaned, e.g. with
steam, before carrying out such operations.
Components in the vicinity must be protected with non-inflammable material and, if the operation is to be performed close to
parts of the lubrication system or in the vicinity of components that may contain oil or inflammable liquids, the system must
first be purged.
Never use an open flame as a light source to inspect parts of the unit.
For all units establish a suitable time interval for cleaning procedures.
If replacement parts are needed use only original spares.
Take care not to damage pressure limiting devices.
All guards must be refitted after carrying out repair or maintenance work.
Check the direction of rotation of the motors (the pump, if installed) when starting the unit for the first time and after
work has been performed on the electrical connections or on the power supply sectioning device.
Do not use flammable liquids to clean the unit when it is running. If chlorinated hydrocarbon non-flammable fluids are used
for cleaning, safety precautions must be taken against any toxic vapours that may be released.
Before removing any panels or dismantling any part of the unit, carry out the following operations:
- Isolate the unit from the electrical power supply by disconnecting the supply upstream of the power feeding line.
- Lock out the disconnect switch in the “OFF” position by fitting a padlock.
- Affix a tag to the disconnect switch handle stating “WORK IN PROGRESS - DO NOT SWITCH ON”.
- Do not set the electrical power switch to ON or attempt to start the unit if it has been tagged out with a warning sign.
Coloured tracers can be used in service-maintenance operations.
Inspect all refrigerant circuit unions including connectors, flanges, and more generally all critical points (open unions) in
order to prevent possible leakage of refrigerant gas.
