6.1 Cleaning
NOTE
Damage to the device during cleaning
Malfunctions possible
→ Do not clean the device using a high-pressure
cleaner. Do not use acid, alkali or solvent-based
cleaning agents.
→ Do not use any pointed or sharp-edged objects
for cleaning.
Instructions for cleaning

Check the unit regularly, with particular attention to
smooth operation and dust build up on the impeller
and motor housing.

Heavy dust build up, especially on the motor housing
and the impeller, and/or strong vibrations, can
destroy the fan. In this case, switch off the fan
immediately and clean it.

If heavy corrosion is identified on load-bearing or
rotating parts of the unit, switch it off without delay
and replace it. Repair of load-bearing or rotating parts
is not permitted.

Only clean the unit when it is stopped; disconnect it
from the power supply and secure it against
restarting.

Do not use aggressive cleaning agents!

Only direct water jets at the rotor side, never at the
motor side.

Avoid directing the water jet at the condensation
drainage hole. Maximum water pressure: 80 bar.

After cleaning, run the fan for at least an hour at
maximum speed.

Make sure that the condensation drainage hole (if
present) is not obstructed by dirt.

Adjust maintenance intervals to the level of dust
exposure.
6.2 Safety inspection
NOTE
High-voltage test
The integrated EMC filter has Y capacitors. The
trigger current is exceeded when AC testing voltage
is applied.

Test the device with DC voltage when you
perform the legally required high-voltage test.
The voltage to be used corresponds to the peak
value of the AC voltage required by the
standard.
