7 Installation
PLEASE 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
Permissible ambient temperature adhered to (see Section 5 "Techni-
cal data" on page 10)
n
Room of sufficient size to allow trouble-free assembly as well as in-
spection and maintenance of the device at all times
n
Power supply available
n
Room must comply with the locally valid prescriptions
7.2 Installing the device
i
This section applies to devices with a mounting plate. Devices
without a mounting plate are supported by the pipe line. The
pipe line requires adequate support.
Fit the device on an easily-accessible, vertical wall surface. The control
should be mounted at roughly at eye-level.
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 SW10
Perform the following working steps:
1.
Hold the device against the wall and align it horizontally.
2.
Mark the mounting point on the wall.
3.
Drill in the marked holes and insert the rawlplug.
4.
Place a washer on each screw.
5.
Screw the screws through the mounting plate into the anchors until
the mounting plate is flush with the wall.
6.
Tighten the screws.
ü
The device is fitted on the wall.
7.3 Hydraulic installation
You can use the following connection types:
n
Fixed piping with NPT thread
n
Fixed piping with flange connection
All connection types are suitable for gaseous chlorine and liquid chlorine.
The maximum flow rate of the device is stated in section 5 „Technical
data“ on page 10. It has been calculated for the entire piping system:
from the chlorine drum to the vacuum regulator. The calculation was per-
formed with the usual pipe lengths:
Where required, a large distance can be bridged with pipes of a higher
nominal width. A pipe line with a connection nominal width is only used
for shorter sections shortly before and after the device.
7.3.1 Creating the threaded connection
PLEASE NOTE
Leakage due to incorrect installation
In order to provide safe and long-term effective sealing, the thread seal-
ant must form an even layer. Errors during installation can result in the
thread sealant losing its sealant properties (uneven application or air
bubbles) which will result in leakages.
ð
Only turn the thread clockwise and never in two directions. This can
result in air bubble formation.
ð
If the orientation needs to be corrected after the connection has
been tightened, repeat steps 1 – 5.
DANGER
Leakage due to incorrect sealant.
Pipe connections and fittings in pressurized lines must be sealed with
chlorine-resistant substances. Unsuitable sealants react with the chlo-
rine and lead to leakages.
ð
Use only sealants that are resistant in contact with chlorine (e.g.
anaerobic sealants).
Precondition for action:
ü
The inside of the line is clean and dry.
ü
The threads are metallic bright.
ü
The pipe line is fixed with pipe clamps and meets the connection in
an voltage-free state.
