IMPORTANT:
When the system is placed in operation, it is checked out by the DRAABE customer service
technician for conformity to specifications. The technician is authorised to cancel initial op-
erations if the installation is found to be erroneous.
5.4 Electrical Installation
The documentation does not cover the installation of the voltage supply. However, require-
ments placed on this supply are treated. The installation of the electric components of the
pure water system is shown together with the place where the voltage supply must be ap-
plied.
CAUTION:
The electrical installation, including the voltage supply, must conform to all local safety
regulations and standards.
IMPORTANT:
-
Be sure to put the attachment cables through the cable run that is supplied.
-
The cable ends are to be fitted with suitable cable end sleeves.
-
Observe the values indicated for fuse protection.
-
The installation may only be carried out in accordance with the diagrams gone into
here.
-
During installation the voltage supply must be turned off and secured against acciden-
tal activation.
5.4.1 Water Softener
The water softener is delivered with a 12V network part and is ready to connect. For new
installations, solely the water softener SoftCab will be used. But for the sake of complete-
ness, the AC is described, too.
5.4.1.1
Water Softener Type AC
The type AC2101 is consumption driven. This means, that the regeneration time depends
on the water consumption.
consumption driven
A consumption driven water softener (AC2101) is to be connected with the clean water sys-
tem by means of the 5 pole plug delivered with it. A micro processor in the clean water sys-
tem calculates the times of regeneration in dependence on water consumption and when
these times are reached it sends a signal to the AC.
5.4.1.2 Water Softener Type SoftCab 25 DR
The water softener has to be connected to the pure water system by using the 5-pin-lug (in-
cluded in delivery). The water softener can run both time-controlled and quantity-controlled.
The time-controlled mode executes the regeneration at a fixed time. When running the
quantity-controlled mode, the microprocessor of the SoftCab 25 DR calculates the point in
time for the regeneration subject to the water consumption. When reaching the time for the
regeneration, the SoftCab gives a signal to the pure water system. The respective mode
(time- or quantity-controlled) is defined ahead of delivery. When starting up the water sof-
