Installation
Always completely disconnect the relevant plant part before in-
stalling the instrument or connecting/disconnecting it to/from the
power supply. Secure the plant against reconnection.
Only connect the instrument to the mains voltage specified on the
rating plate.
Always observe technical data and ambient parameters.
Testomat 2000® THCL requires an interference free and stable
power supply. If necessary, use a mains filter to protect Testomat
2000® THCL against interference voltages caused, e.g., by sole-
noid valves or large motors. Never lay connecting cables parallel to
power cables.
Operation
Ensure that the maximum electrical load capacity of the relay out-
puts is never exceeded.
Immediately switch off Testomat 2000® THCL and contact service
staff if malfunctioning occurs. The warranty will be void if you tam-
per with or attempt to repair Testomat 2000® THCL. Repairs must
be carried out by authorised service staff.
After switch-off and longer downtime
Ventilate the indicator leads as described in the start-up, because
longer downtimes (more than 6 hours) can cause the indicator in
the leads to retract.
Do not switch off the appliance for longer periods (e.g. over the
weekend) via the start/stop output. The indicator can retract from
the leads. This results in measurement errors after the appliance is
switched on.
Cleaning
Only use a dry, lint-free cloth for cleaning.
De-installation
Prior to de-installing a defective instrument, always write down a
description of the error (failure effect). It is only possible to repair a
defective instrument (irrespective of the warranty period) if it has
been de-installed and returned to us with a description of the error.
Disposal
Dispose of the instrument in accordance with national regulations.

Application instructions
Wait at least 5 seconds before switching the instrument on and
then off again at the main switch.
In order for Testomat 2000® THCL to operate reliably, use Heyl
Testomat 2000® indicators. Operate in the pH-range 4 – 10.5,
when determining the total hardness!
With Testomat® instruments for water hardness monitoring, larger
quantities of heavy metal ions in the softened water might influ-
ence the colour reaction, especially iron above 0.5 mg/I, copper
above 0.1 mg/I and aluminium above 0.1 mg/l (brownish-red col-
our display).
If the measuring water contains more than 20 mg/I CO2 (carbonic
acid), incorrect evaluations cannot be excluded.
The concentration of influencing contents can be determined by
using our colourimetric TESTOVAL® test kit.
Careful handling of the instrument increases both its operational
reliability and service life! Therefore, carry out a visual inspection
at regular intervals as described below:
- Has the use-by date of the indicator expired?
- Are the hose connections of the dosing pump free of leaks?
- Is there air inside the dosing hoses?
- Are all the water connections free of leaks?
- Are the doors of the instrument closed properly?
- Is the instrument heavily soiled?
- Are the measuring chamber and the drain duct/drain hose
clean?
Trouble-free operation is only possible when maintenance is car-
ried out on a regular basis (For maintenance and service instruc-
tions, please refer to the section entitled Maintenance and the
"Maintenance manual of Testomat 2000® / ECO®")
If problems occur, please refer to the section entitled Error mes-
sages/Troubleshooting.
No opening of the measuring chamber holder!
Do not open the measuring chamber holder. You cannot carry out
any repairs in this area, but damage the device. If you open the
measuring chamber holder, your warranty will expire.

required. The instrument is factory set for the operating range of 1 to
8 bar. Remove the flow controller valve body to operate the in-
strument in the operating range of 0.3 to 1 bar (e.g. when using an
aerator type R). This involves removing the retaining pin from the
controller/filter receiver . Subsequently use the metal bracket to
remove the controller plug from the borehole. Then remove the
flow controller valve body and reinsert the controller plug and the
retaining pin.
Installing Testomat 2000® THCL
