Operating requirements
 In order for Testomat
®
808 to operate reliably, use Heyl Tes-
tomat
®
indicators in the pH-range 4 – 10.5!
 Only operate the instrument with the parameters specified under
“Technical data”.
 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 CO
2
(carbonic
acid), incorrect evaluations cannot be excluded. In this case, use
an aerator (e.g. special Heyl accessories).
 The concentration of influencing contents can be determined by
using our colorimetric TESTOVAL
®
test kit
 Important! Excessive carbonate hardness and also the ex-
istence of disinfectants in the water can result in erroneous
evaluations.
 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 any 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 more information, please refer to
the section entitled “Maintenance” on page 36.
 If problems occur, please refer to the section entitled “Error mes-
sages/Troubleshooting” on page 32.
