Maintenance guide
At least once every 6 months, pour a bactericidal solution into the tank, to prevent
accumulation of residues and sludge at the bottom that may cause the pump to mal-
function.
NB
: Users must check that any chemicals contained in the condensate are compatible
with operation of the pump.
IMPORTANT
: Test pump operation by filling it with water until the motor starts, to
check for any leaks and verify correct drainage of the water.

10.15 Maintenance
This section is extremely important for correct operation of the appliance. Just a few
operations completed scrupulously and regularly will avoid serious damage to the com-
ponents. Access to the unit is only allowed to authorised and specifically trained per-
sonnel.
The maintenance operations can be summarised as follows:
•
cleaning the air filter
•
checking and cleaning the drains
•
general examination of overall appliance operation
•
Vvisual check of the condition of pressurised vessels
General examination of operation
This is a general examination aimed at comparing the operation of the appliance with
the last check performed. Consequently, any differences in the operating characteri-
stics over time can be highlighted.
A detailed and periodical visual check of the appliance and general cleaning are
always important to ensure correct operation. The above-mentioned operations can in
general be performed once a month.
Naturally, in special situations and specific installations the frequency may change. A
well maintained system is unlikely to cause disruptions and stoppages to the produc-
tion cycles. After 10 years of operation a complete inspection should be performed to
check, and if necessary replace any damaged/worn components.
