Installation and commissioning
Installation and commissioning must be undertaken only
by authorised technicians!
Installation
The unit should be fixed vertically!
Avoid tension of the housing.
The unit doors swing to the left when they are opened. Please
ensure that there is sufficient space for opening them. In this
way, you facilitate the electrical installation and later
maintenance and service work.
Electrical connection
Check supply voltage on the rating plate!
Basic requirement
The external cables (e.g. water meter, interface) should be kept as short as possible and clear of power cables.
Connection
Loosen both fastening screws and open the upper door. Pierce the required rubber cable glands with a screwdriver and
insert the cable (1). Then pull back the cable until the bush (2) has been turned over. Ensure that the leads are held
securely in the terminals, then close the upper door after the installation is completed using the two fastening screws.
Mains water supply
The temperature of the sample water must be between 10 °C and 40 °C. Higher water temperatures can lead to
damage to all parts coming into contact with water (e.g. filter housing, measuring chamber)!
Lower water temperatures can cause misting on the sight-glass windows.
L
In the event of higher temperatures, the KCN type cooler must be installed in the branch line of the Testomat
®
2000 THCl.
Hot water can cause scalding!
The sampling tube to the Testomat
®
2000 THCl must be equipped with a hand-operated shut-off valve and be kept as
short as possible (not longer than a maximum of 5 metres). It is important that the branch line connection is taken
vertically from the top of the main soft water line in order to prevent dirt particles from entering into the measuring
chamber. Remove the valve body out of the regulator/ filter housing when operating the Testomat
®
2000 THCl with a
pressure range of 0.1 to 1 bar.
Plug connector
The unit is equipped as a standard with a plug connector for opaque plastic hoses 6/4 x 1 (external diameter 6 mm/
internal diameter 4 mm).
Quick-acting coupling (accessory: optional adapter for water inlet, item no. 40123)
When fabric reinforced pressure hoses (e.g. for existing installations) are used, please replace the plug connector at the
controller and filter housing with a plug for the quick-acting coupling (not included with the delivery).
Water to drain
The feed water flows through the measuring chamber then, via the outlet pipe, to the drain (hose connection internal
diameter 14 mm). Make sure, by using a funnel for example, that the water can run freely to drain and cannot back-up
into the measuring chamber. A hose impervious to light should also be used for the drain pipe (to discourage algae
formation).
