3. Precautions for repairing the Wels-WelsR290 1000 R290 in the presence
of inflammable refrigerant gas - R290 (PROPANE)
This type of cabinet with inflammable refrigerant gas is identified by the labels applied to the
important components:
The refrigerant gas circuit must be intact in order to avoid leaks into the
environment since, in contact with air, the gas can create a fire risk in the
presence of open flames or sparks caused by electrical equipment.
To avoid this danger, only use appropriate components. If the components must be
replaced, it is important to use original spare parts that have been approved for their
intended use.
Interventions to be performed following breakdowns or malfunctions must be
performed by qualified personnel who, after having evaluated the nature of the
problem, take action in full respect of the safety regulations regarding this type of gas.
The tools necessary for carrying out interventions on the equipment must
respect the same regulations as system components, avoiding the use of
electric tools and open flames when in presence of inflammable gas.
Any leaks in the components of the refrigeration circuit are retained permanently, as a
consequence of all the parts of the circuit being inaccessible.
In particular, it is not possible to carry out refrigerant filling, draining, emptying, or
recharging operations because the entire refrigeration circuit is hermetically sealed.
If a compressor malfunction occurs that requires replacement, this operation
cannot be performed at the customer's premises. The cabinet must be shipped to
an authorised ARNEG service centre for repair.
Contact a local reseller for additional information. Contact an after-sales service
technician to clarify any doubts.
ANY OTHER USE NOT EXPLICITLY INDICATED IN THIS MANUAL IS TO BE
