10. MAINTENANCE
The dryer's worst enemy is the fluff on clothes. The machine in general and its parts must not
have any fluff that might hinder its operation.
The machine must be vacuumed and generally cleaned once a month.
The machine's performance is largely determined by the cleanliness of its components.
The machine operation does not require any type of maintenance. Bearing greasing is permanent
for the machine's entire useful life.
10.1.
Fluff filter
Filtro primario
The fluff filter should be cleaned once every 4 or 5 hours of operation to obtain maximum
performance in the machine.
To clean the filter in the self-service machines, proceed as for the OPL dryers. See section 2.1
with the difference that the handles have a lock with key.
Secondary filter
The secondary filter must be replaced every 200 hours of service. Total and partial meters of the
use of the machine are displayed in the menu. See section 9.3.
10.2.
2000 h (annual) service
Fan: Check the blades are clean. Blocked blades prevent the air from circulating.
Heat exchangers: Use a pressure hose to blow air through the batteries in the opposite
direction to the normal air flow, collect up the particles and/or pieces of filter where
applicable.
Coolant circuit: Inspect for oil or coolant leaks, and for noise and vibration of the system
components. Take temperature and pressure readings of various components and record
on the maintenance sheet.
Water circuit: Check the condition of the water filters.
10.3.
10000 h (5-yearly) service
Heat exchangers: Every 5 years, clean the
batteries with soap (suitable for use with
aluminium) and water, and then dry with dry
air at low pressure. Never use a wire brush to
clean the batteries.
Do not use high pressures to clean the batteries to
prevent damage to the fins, etc. The pressure
should not exceed 6 bar.
