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.
Bearing greasing is permanent for the machine's entire useful life.
10.1. Fluff filter
It is advisable once every 4 or 5 hours of operation to clean the fluff filter to obtain maximum
performance in the machine.
To clean the filter, proceed as in the OPL dryers. See section 2.1 except that handles have a
key lock.
10.2. Heating battery
In the case of electrical heating, clean the accumulated fluff and dust in the battery once every
two months to avoid risks.
In the case of steam or thermal oil heating, clean the accumulated fluff and dust in the filter in the
side part of the battery once every two months to avoid risks. After 3 years, thoroughly clean the
battery using compressed air in the direction opposite to the air. Passing the device through the
blades crosswise may damage the blades.
10.3. Air extractor
Check once a month cleaning fan blades (for DS/DL-11/17 and 23).
Check once a year cleaning the fan blades (for DS/DL-28D and DS/DL-35D).
Blades and blocked conduits prevent the air from circulating.
10.4. Transmission belts (ONLY FOR DS/DL-28D / DS/DL-35D):
The correct tightening of the belt must be checked once a year.
If the belt is not tight enough, it might become prematurely worn. If it is too tight, it might
damage the motor or drum shaft bearings.
Contact your technical service to carry out this operation.
