Unit heaters (2-stage three-phase motor/1-stage AC single-phase motor/continuously variable EC single-phase motor)
Installation and operating instructions
Never use aggressive, paint-dissolving cleaning
agents to clean the unit heaters.
Make sure that no water enters the inside of the
motor or the electronics (possibly by direct
contact with seals or motor openings and note
the protection rating (IP).
Check the condensation water openings,
positioned to fit the installation position, to
ensure that water runs off freely.
No warranty can be offered for corrosion / paint
adhesion of unpainted / painted fans in the
event of improper cleaning of fans.
Run the fan for a minimum of 1 hour at 80 to
100% of maximum speed before cleaning to
avoid the accumulation of moisture in the motor.
Run the fan for a minimum of 2 hours at 80 to
100% of maximum speed after the cleaning
process!
The unit heater's external rotor motor is maintenance-free. The
motor's ball bearing runs, sealed on both sides, are greased for
life. Deposits on the blades of the fan and the fan guard reduce
the air volume. Regularly check the fan, inlet nozzle and fan
guard (-> Heat exchanger) and clean if dirty.
Please refer to the operating instructions for the respective fan
for further information.
Once work has been completed, remove the reconnection
safety guard.
