Operating Testomat
®
808 in the pressure
range 4 to 8 bar
Prior to installation, please check whether a higher operating pres-
sure (between 4 and 8 bar) is required. Use a pressure controller (art.
no. 37602) for ranges between 4 and 8 bar. Optimum operation of
Testomat
®
808 is achieved with operating pressure of between 2 and
4 bar.
Information for trouble-free operation
The water pressure must be between 1 and 8 bar; a pressure re-
ducer should be used for the 4 to 8 bar range (special accesso-
ries). This pressure regulator must be set under flow pressure!
Avoid strong pressure fluctuations.
Connecting the water inlet and outlet
Information for trouble-free operation
Ensure there are no foreign particles bigger than 150 µm which
caused blocking. Use our candle filter (Art. No. 37583) at the front
end of the device if you have problems with blocking.
The measuring water temperature must be between 10°C and
40°C.
For water temperatures above 40°C, install the KCN type cooler in
the supply line of Testomat
®
808.
Water inlet
The measuring water is taken from the main water line of the water
treatment plant and fed to the inlet connection of Testomat
®
808. The
instrument is equipped with a plug connector for plastic hoses 6/4 x 1
(external diameter 6 mm/ internal diameter 4 mm, wall thickness 1
mm) as standard).
Install the connection for the branch line of Testomat
®
808 directly
at the main water line directly after the water treatment plant.
Always lay the branch line connection vertically upwards in order to
prevent dirt particles from entering the instrument from the main
water line.
We recommend you to install a manually operated stop valve (see
figure “Plant example Testomat
®
808” on page 15) in the branch
line to Testomat
®
808.
Use an opaque plastic hose 6/4 x 1 (max. length 5 m) for the water
inlet .
Flush the supply line to remove any dirt particles.
