Connecting the water inlet and outlet
Information for trouble-free operation
The water pressure must be between 0.3 bar and 8 bar
Avoid strong pressure fluctuations
The measuring water temperature must be between 5 °C and
30 °C
For temperatures above 40 °C, the KCN type cooler should be
installed in the branch line of Testomat 2000
®
PO4.
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 2000
®
PO4. 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 2000
®
PO4
directly at the main water line
directly after the water treatment
plant
It is important that the branch line connection is laid vertically
upwards in order to prevent dirt particles from entering the
instrument from the main water line.
Install a manually operated shut-off valve
in the branch to
Testomat 2000
®
PO4.
Use an opaque plastic hose 6/4 x 1 (max. length 5 m) for the water
inlet
.
Flush the inlet to remove any dirt particles.
When operating within a
pressure range of 0.3 to 1 bar or with a
supply via a booster pump, please remove the valve body from the
controller and the filter housing. The pump should have a feeding
capacity of between 25 and 35 litres/hour and be resistant to the
medium being measured.
When using a cooler
The hot water can cause burns and damage wetted parts of
Testomat 2000
®
PO4.
Water outlet
The feed water flows through the measuring chamber to the drain via
the outlet hose.
Connect the outlet connection of Testomat 2000
®
PO4 to an outlet
hose
(internal diameter 12 mm).
Lay this hose
without
backwater development
and any
syphoning effect, e.g. via an open funnel, to the drain.
