PERIODIC MAINTENANCE AND INSPECTIONS
13.1 WARNINGS
13
All the operations described in this chapter must always be carried out
by qualified personnel.
Before performing any intervention on the unit or accessing internal
parts, make sure that the power supply has been disconnected.
The flow pipes and compressors are hot. Pay particular attention when
operating in the proximity.
Pay special attention when operating in the proximity of the finned coils
as the aluminium fins are particularly sharp.
The compressors, the flow pipes and the dissipator of the inverter are
hot. Pay particular attention when operating in the proximity.
Warning: the inverter of the compressor contains various parts
that remain live for a few minutes after the power supply has been
disconnected at the main switch. Before carrying out any maintenance:
– turn off the machine at the main switch;
– wait at least 5 minutes;
– always use a suitable multimeter to make sure that there
is no dangerous voltage at the heads of the clamps;
– always make sure that the motor of the compressor has completely
stopped. Freely rotating motors can create dangerous voltage at the
clamps of the inverter even when this is not powered;
– check that the dissipator is not hot: coming in contact with the
dissipator can cause serious burns.
It is mandatory to use Explosimeter during any stage of ordinary
and extraordinary maintenance and start-up phase.
It is forbidden to carry out maintenance with the machine is on.
It is mandatory off the power supply before any maintenance.
Where it is necessary to intervene on the circuits or vessels containing
refrigerant, these must first be depressurized, drained and
reclaimed (inert gas injection).
