12 Cleaning, maintenance
Cleaning intervals are to be determined by the
operating company. Cleaning frequency depends
on ambient conditions and anticipated impair-
ments.
Before cleaning, switch off mains fuse, secure against be-
ing accidentally switched back on and position a warning
sign. If required, the unit is cleaned with a dry cloth.
EZR, DZR fans are maintenance-free.
Despite this
, check
the unit from time to time
for bearing noise, damage and
disproportionate vibration. If necessary, clean the fan as
described above.
Never use water or a high-pressure cleaner to
clean the interior.
13 Fault rectification
Fault finding and repairs only permissible when
carried out by qualified electricians.
When the unit is at a standstill, check whether
the thermal overload protection of the motor has
reacted. Once the thermal overload protection has
cooled down, switch on the fan and check for un-
usual noise.

15 Dismantling and environmentally sound
disposal
Old devices and electronic components may
only be dismantled by specialists with electrical
training.
Proper disposal avoids detrimental impact on
people and the environment and allows valuable raw ma-
terials to be reused with the least amount of environ-
mental impact.
Do not dispose of the following compon-
ents in household waste!
Old devices, wearing parts (e.g. air filters),
defective components, electrical and elec-
tronic scrap, environmentally hazardous li-
quids/oils, etc. Dispose of them in an envir-
onmentally friendly manner and recycle
them at the appropriate collection points (→
Waste Disposal Act).
1. Separate the components according to material groups.
2. Dispose of packaging materials (cardboard, filling ma-
terials, plastics) via appropriate recycling systems or re-
cycling centres.
3. Observe the respective country-specific and local regu-
lations.
