ROUTINE AND UNSCHEDULED MAINTENANCE
BEFORE CARRYING OUT ANY TYPE OF MAINTE-
NANCE, DISCONNECT THE UNIT FROM THE POWER
SUPPLY.
• The user is responsible for ensuring correct maintenance
of the appliance.
• The maintenance operations must be carried out by quali-
fied personnel.
• If needing to dismantle the unit, wear suitable personal
protective equipment.
Routine maintenance plans are intended to keep the unit
operating efficiently, extend its working life and prevent
faults and malfunctions.
The manufacturer therefore recommends the use of a unit
logbook that includes such maintenance plans, in accor-
dance with European legislative requirements;
all work performed on the unit will be entered in the logbook,
recording the date, type and description of the work per-
formed, any measurements made, faults found, alarm log,
etc.
