...2 INSTALLATION

2.3 Preparing the Electrode Cartridge – Fig. 2.6

Important Note. Before preparing the electrode cartridge,

read through Section 2.4 to become familiar with the

appropriate installation procedure.

The procedure in Fig. 2.6A is appropriate for both pH and

redox (ORP) electrode cartridges. The cartridge is supplied

with a protective cap filled with a 7 pH buffer solution and

should not require pre-conditioning; it is ready for immediate

use.

Unwind adhesive tape.

Note. Retain protective cap and tape for future use.

Shake gently

to dislodge air

bubbles.

2.4 Installing the Electrode Cartridge – Fig. 2.6

Caution

• Ensure an 'O' ring is fitted to seal each cable connector.

• Tighten each plug to ensure a good seal. It is vital that

the terminations are kept dry at all times.

• Ensure the cable is fed through the dip system tube

before the cable is connected. To avoid the risk of damp/

corrosive air damaging the cable plugs, connect to the

electrodes as soon as possible.

2.4.1 In-line pH Systems

a) Fit the flow cell into the pipeline observing all safety

precautions. Fit isolating valves where necessary to

enable safe access to the sensor for maintenance

purposes.

b) Ensure that all connections are tight.

c) Connect the tagged end of the cable to the 4600 Series pH/

Redox meter – see Fig. 2.7 and Table 2.1.
