2.2 Water Supply for Water Wash Systems –

Fig. 2.4 and 2.5

Important Note. Installation must only be carried

out in accordance with the local water authority and

council bylaws.

Caution. The maximum water pressure at the

electrode should not exceed 4 bar. At NO time should the

sample pressure be allowed to exceed that of the water

wash water supply. Fit a non return valve if this possibility

exists.

Information. As all quick-fit connectors used in

Water Wash systems incorporate cutoff valves, tubes

may subsequently be disconnected on operational

equipment without sample loss or water wash discharge.

Suitable Solenoid Valve (user supplied)

Connect a suitable length of

solenoid valve. This tube terminates at the electrode installation point.

Note. For optimum performance of the Water Wash

function in flow systems, the sample pressure should be

at least 2 bars lower than that of the water wash water

supply.

The water supply for the water wash system must come from a

suitable supply via a solenoid valve. The general specification

for the solenoid valve is:

Brass body: 2/2, NC

Orifice size: 3.0 / 4.0 mm

Port size:

" –

" BSP

Pressure:

0 to 6 bar

Coil:

110/115 V a.c. or 230/240 V a.c. 50/60 Hz

Before fitting the electrode cartridge system, install the water

supply as shown in Fig. 2.3.

Note. See Fig. 2.4 for recommended tubing.

Install a suitable solenoid valve to

the mains water supply feed.

Note. It is advisable to use a

suitable hose clamp.
