Ariston 801 Instructions For Installation, Use, Maintenance page 46

When brazing is required, the following procedures shall be car-
ried out in the right order:
- Remove the refrigerant. If the recovery is not required by nation-
al regulations, drain the refrigerant to the outside. Take care that
the drained refrigerant will not cause any danger. In doubt, one
person should guard the outlet. Take special care that drained
refrigerant will not float back into the building.
- Evacuate the refrigerant circuit.
- Purge the refrigerant circuit with nitrogen for 5 min (not required
for A2L refrigerants).
- Evacuate again (not required for A2L refrigerants).
- Remove parts to be replaced by cutting, not by flame.
- Purge the braze point with nitrogen during the brazing proce-
dure.
- Carry out a leak test before charging with refrigerant.
- Reassemble sealed enclosures accurately. If seals are worn, re-
place them.
- Check safety equipment before putting into service.
d) Decommissioning
- If the safety is affected when the equipment is putted out of
service, the refrigerant charge shall be removed before decom-
missioning.
- Ensure sufficient ventilation at the equipment location.
- Be aware that malfunction of the equipment may be caused by
refrigerant loss and a refrigerant leak is possible.
- Discharge capacitors in a way that won't cause any spark.
- Remove the refrigerant. If the recovery is not required by nation-
al regulations, drain the refrigerant to the outside. Take care that
the drained refrigerant will not cause any danger. In doubt, one
person should guard the outlet. Take special care that drained
refrigerant will not float back into the building.
- When flammable refrigerants are used,
– Evacuate the refrigerant circuit.
– Purge the refrigerant circuit with nitrogen for 5 min.
– Evacuate again.
46 / EN
– Fill with nitrogen up to atmospheric pressure.
– Put a label on the equipment that the refrigerant is removed.
e) Disposal
Ensure sufficient ventilation at the working place.
- Remove the refrigerant. If the recovery is not required by nation-
al regulations, drain the refrigerant to the outside. Take care that
the drained refrigerant will not cause any danger. In doubt, one
person should guard the outlet. Take special care that drained
refrigerant will not float back into the building.
- When flammable refrigerants except A2L refrigerants are
used,
– Evacuate the refrigerant circuit.
– Purge the refrigerant circuit with nitrogen for 5 min.
– Evacuate again.
– Cut out the compressor and drain the oil.
- Evacuate the refrigerant circuit.
- Purge the refrigerant circuit with nitrogen for 5 min.
- Evacuate again.
- Cut out the compressor and drain the oil.
Pursuant to Art. 26 of (Italian) Legislative Decree
no. 49 of 14 March 2014, "Implementation of Direc-
tive 2012/19/UE on waste electrical and electronic
equipment (WEEE)"
The barred wheeled bin symbol appearing on the
appliance or on its packaging indicates that the product must be
collected separately from other waste at the end of its useful life.
The user must therefore deliver the decommissioned product
to an appropriate local facility for separate collection of electro-
technical and electronic waste. Alternatively, the appliance to be
scrapped can be delivered to the dealer when purchasing a new
equivalent appliance. It is also possible at premises of resellers of
electronic equipment with a sales area of at least 400 m² to hand
in, free of charge and without any obligation to purchase, elec-
tronic products for disposal with dimensions of less than 25 cm.
Proper separated collection of the decommissioned appliance for
its subsequent recycling, treatment and eco-compatible disposal
helps to prevent negative effects on the environment and human
health, besides encouraging reuse and/or recycling of its constit-
uent materials.
