Note. Allow sufficient cable slack for
positioning/servicing procedure.

With the wall mounting
bracket as a guide, mark
and drill the supporting
structure for mounting the
dip system.

Fit a suitable pipe clamp

around the pipe and lightly
tighten the securing
device.

Position the dip system
in the pipe clamp for
correct monitoring and
tighten the clamp.

Make the necessary electrical
connections – see Section 4
ELECTRICAL INSTALLATION.

Secure the pipe
clamp to the
support structure.

If applicable, arrange to have a water
wash mains supply available – see
Section 3.3 – and connect to the quick
fit connector on the end cap.

Note. Although a mounting
bracket is supplied, the user
may install a device more
suitable for the specific
application, e.g., a 'stilling well'.

Note. A suitable mounting bracket is
required for Imperial kit system.

Note. The submersible
system is provided with a
screw fixing to enable it to be
suspended on a small chain
(not provided). This is to
prevent cable strain and
allows the system to be
lowered to the required depth.

Dip Systems – Fig. 3.4

Note.

• The standard dip system is supplied with the temperature probe and oxygen sensor body fitted. Before fitting the dip tube

to any bracket or fixing, remove the protective shroud, unscrew the dummy capsule from the end of the oxygen sensor
body and fit the oxygen sensor capsule to the sensor body (see Section 5.1 Replacing the Oxygen Sensor Capsule) and
replace the shroud. See section 3.1.2 for assembling dip kit systems.

• If the final mounting position of the dip system is inconvenient for wiring when  fitted, wire the system prior to fixing – see

Section 4 ELECTRICAL INSTALLATION.

3.2.3

Submersible  Systems – Fig. 3.5

Note. The submersible system is supplied with the
temperature probe and oxygen sensor body fitted.
Remove the protective shroud, unscrew the dummy
capsule from the end of the oxygen sensor body and fit
the oxygen sensor capsule to the sensor body (see
Section  5.1 Replacing the Oxygen Sensor Capsule)
and replace the shroud.
