Fasten the cable to the edge inside the units,
using the cable clips.
Warning:
Do not allow the cable to lie or hang

both units.

Fabricate the grommets in the electronic
compartment to measure.

Feed the cable through the wall of the electronic

2.7.3 Connecting an extra controller to the unit
(optional)
The fans have a start-up time of approximately
3 seconds. This can be remedied with an extra
controller which causes the fans to rotate very
slowly if the door is closed.
Note:
The fans also continue rotating slowly at
night. If this is not desired, switch the unit off
at night with the controller that is used for
operating it.
