6.4 Installing the compact booster unit
Make allowance for space for operating and
maintenance tasks.
1. Remove the packaging before installing the system.
2. Mark the 4 mounting points using the drilling template
included.
3. Drill holes (4 x Ø10 mm).
4. Insert suitable, proper sized dowels.
– wall plugs included only for mounting in concrete
and full brick walls.
5. Mount and adjust both of the lower fixing attachments.
6. Set the system in both of the lower fixing attachments.
7. Mount upper fixing attachments.
6.5 Installing the pipelines
Install connecting cable with zero potential. No load is allowed
to be put on either the connections or the system.
Install pressure reducing valve ahead of the system to ensure
that not more than 4bar prepressure is fed from the drinking
water network.
It is recommended to install a stop valve and an external filter.
6.5.1 Water connection
1. Attach inlet connection R
hose to the drinking water line.
2. Fill angular tank with water.
3. Open drinking water line.
– After opening the drinking water line, the tank is
automatically filled.

6.5.2 Pressure connection
Avoid overly bending the flexible connecting pipe, as
this reduces the service life and puts an improper load
on the connections.
To avoid frequently pump activation for small
withdrawal amounts, install membrane pressure
expansion vessel downstream of the CBU. A
membrane pressure expansion vessel is included in
scope of delivery.
It is recommended to install a stop valve.
4. Install membrane pressure expansion vessel in
consumption water line. Set pre-pressure to 3.2 - 3.4
bar. For filling use nitrogen only!
5. Connect the system to the consumption water line
using the flexible pressure hose
6.6 Connecting the overflow
CAUTION!
Overflow not connected
Danger of flooding the installation room!
 Lead the overflow line to a drain with adequate
dewatering capacity (connection DN150).
An overflow for free drain as prescribed by EN 1717 is
implemented, and has a nominal width of 70mm for this
system. This overflow becomes effective when the drinking
water backfeed leaks and the water exceeds the maximal
overflow point.
The absence of backwater prevention due to the
wastewater system leads to the loss of DVGW-
approval! If the systems overflow funnel is missing,
the system must be connected to the wastewater
system with an overflow siphon found in the
accessories. In doing so, it must be ensured that the
overflow siphon is not firmly connected to the system
and that the installation is performed according to DIN
1986-100, EN 1717.
With a secure connection to the wastewater system,
we recommend the installation of a siphon to avoid
unpleasant odour.
1. Connect the overflow.
