7 Installation
NOTE
Damage to the system due to incorrect installation
The failure to observe installation instructions (e.g. use of unsuitable
tools, incorrect torque) can damage the system parts.
ð
Use suitable tools.
ð
Note the specified torque.
7.1 Installation location
The changeover unit is fitted in the room of the chlorine supply.
The room must fulfil the following requirements:
n
secured against access by unauthorised persons,
n
protected against weather conditions,
n
frost-free,
n
permitted ambient temperature maintained (see Section 5 "Technical
data" on page 9),
n
room of sufficient size to allow trouble-free assembly as well as
inspection and maintenance of the device at all times,
n
an electrical connection is given,
n
the room must comply with the locally valid prescriptions.
7.2 Installing the device
Install the device on a vertical even wall. The control should be mounted
at approx. eye-level.
Fig. 5: Attaching the wall plate
Precondition for action:
ü
A flat wall.
ü
The mounting material is suitable for the wall.
Resources required:
@
Water level
@
Drill
@
2 open-end spanners SW13
Perform the following working steps:
1.
Hold the device against the wall and align it horizontally. The mount-
ing position is shown in section 7.5 “Installation examples” on
page 14.
2.
Mark the mounting point on the wall.
3.
Drill in the marked holes and insert the rawlplug.
4.
Screw in the stair bolts (1) a into the rawlplug until the wooden
thread seals with the wall surface.
5.
Place a nut (2) and washer (3) on every screw.
6.
Push the wall plate (4) onto the hanger bolts.
7.
Place a washer (5) and a cap nut (6) on every screw.
8.
Adjust the nuts (2 + 6) so that the wall plate is held evenly and with-
out tension.
9.
Tighten the nuts.
ü
The device is fitted on the wall.
7.3 Hydraulic installations
PVC-U pipes or PE hoses are used as conduits. If the line is to supply mul-
tiple consumers, the line should be calculated for the total of the con-
sumption volume.
The following nominal widths are recommended for the vacuum line
(pressure loss max. 25 bar, calculated at 0.9 bar (a) with 4x90° angles):

Where necessary, a large distance can be installed in a large nominal
width and a connection in the nominal width of the device can be select-
ed for shorter sections shortly before and after the device.
