Installation and Operating Instructions

FUNCTION
4.0
Function description
1. Switch-on delay
The fan turns on only after the set delay time (0, 45, 90, 120 sec.). By mutual
activation the light function can be switched on for a short time without fan coming on
stream. Turn-on delay performs only after coming to a complete stop of the fan.
When switching between current stages – ignore applicable switch-on delay. By
mutual activation of both stages, turn-on delay can be considered only when time
function is activated on both stages.
2. Push button operation
If there is no switch-on delay (DIP 1 / 2 off / off) activated, then switch inputs 1 or 2
can be controlled by a push-button. For this relevant stage time function should be
activated.
The button must be pressed for more than 0.5 seconds. As soon as the stage will be
activated by the push-button, the corresponding stage will switch off itself at the end
of the run on time.
3. Shut down
By switching off the current stage the fan will turn off only after the set lag time has
elapsed. The length of the run on time can be adjusted (6, 10, 15, 21 minutes).
When switching between the stages, the run on time will be ignored. By mutual shut-
down of the both stages, the run on time will be considered only when time function
will be activated on both stages.
4. Intermittent operation
The fan can be set at adjustable intervals to perform automatically. The intervals can
be adjusted (0, 8, 12, 24 hours). During the interval mode adjusted post-run time
corresponds to the duration of the cycle. Intermittent operation starts after the last
turn-off. The required ventilation is the overriding importance for the intermittent
operation. In the interim required ventilation, started interval time will reset and
restart after the shutdown.

Cleaning
Safety instructions listed in Chapter 1.2 should be observed
!
- Before cleaning always ensure that the fan is isolated from the power supply and
secured against restarting!
- Clean cover, protective guard and visible housing parts (the external housing of the
fan) with a damp cloth!
- Do not use any aggressive or paint solvent cleaning agents!
- High pressure cleaners or water sprays should not be used!
5.1
Cover dismantling
1. Isolate the fan from the power supply and secure against restarting.
2. Pull the side pieces (cover plates) of the upper part of the housing outwards (see
