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.
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:
1 /
8
" – 1 /
4
" 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.
