3.2.2 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.

Fit a suitable pipe clamp

around the pipe and lightly

tighten the securing

device.

Make the necessary electrical

connections – 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.

Note. Although a mounting

bracket is supplied, the user

may install a device more

suitable for the specific

application, e.g., a 'stilling well'.

With the wall mounting

bracket as a guide, mark

and drill the supporting

structure for mounting the

dip system.

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.

3 MECHANICAL INSTALLATION...

Note. A suitable mounting bracket is

required for Imperial kit system.

Note. Allow sufficient cable slack for

positioning/servicing procedure.

Position the dip system

in the pipe clamp for

correct monitoring and

tighten the clamp.

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.
