Operating requirements

• Problem-free operation of the Testomat
when using Heyl Testomat indicators and only within the pH range
of 4 – 10.5! Using external indicators may invalidate the guarantee.
• Only operate the device within the scope of parameters specified
under "Technical Data".
• For Testomat
®
devices used to monitor water hardness, large
quantities of heavy metal ions in the hardened water may disturb
the color reaction, particularly
o
Iron over 0.5 mg/I
o
Copper over 0.1 mg/I
o
Aluminum over 0.1 mg/l (brown-red color indication).
• If the test water contains more than 20 mg/I CO
erroneous evaluations cannot be ruled out. In this case, use an ir-
rigator (e.g. optional accessory from Heyl Co.).
• The water to be measured must be clean and free of bubbles!
• The concentrations of disruptive ingredients can be determined
with colorimetric TESTOVAL
• In the event of
o
excessive carbonate hardness
o
the presence of disinfecting agents
o
the presence of silicate (used to protect pipes), the measur-
ing chamber may become soiled, which over time
may lead to erroneous evaluations
• Careful handling of the device enhances the operational safety and
the service life! With this in mind, perform a visual inspection of the
device at regular intervals as follows:
o
Has the expiry date of the indicator elapsed?
o
Are the hose connections of the dosing pump leakproof?
o
Is there any air in the dosing hoses?
o
Are all water connections leakproof?
o
Is the door of the device carefully closed?
o
Is the device excessively soiled?
o
Are the measuring chamber and drain channel/drain hose
clean?
• Problem-free operation is contingent on regular maintenance!
Maintenance and care instructions can be found in the
and maintenance" section.
• Indications of problems can be found in the
es/troubleshooting" section.
