Maintenance and service

Decalcification and changing of filter (see sections 6.4, 6.5) should be carried out immediately by the user when required.

Saftey-technical inspection 6.1

Functional test Test



 Switch unit several times on and off.  Correct function of mains pilot lamp and solenoid valve (clacking).  Automatic activation of the thermal process for reducing bacterial count.



 Shut-off main water tap and observe temperature indication.  After a few seconds error signal will appear "F1" (= no water).



 Testing the displays.  All optical and audible indicators issue their signal during the first second after switching on (in particular segmental test "8 8 ").



 Set all temperature setting switches on 40°C and test consecutively by touching the corresponding keys whether in all ranges 40°C is reached in ACTUAL temperature indication. • Spray off and check water temperature by hand. • Carry out the same test with temperatures 37°C and 28°C.  The particular combination of temperatures 40°C, 37°C and 28°C, as well as the test in all ranges ensures a comprehensive test of all contacts of the pre-setting switches, in ON- as well as in OFF-position, and also testing of all components involved in temperature control of the DESIRED temperature control system. Therefore, carrying out a test in one range only, or at only one temperature is not permissible.



 Set temperature at 49°C.  The electronic excess-temperature protection must respond (in the temperature display error code "F7" appears).



 Measure temperature of water splashed off at standard settings: 30°, 37° and 44°C.  The value may not deviate more than ± 0,5° ± 1/2 digit, i.e. 1°C in total. Typically, however, values are better than ± 0,5°C. This measurement is critical !

Measuring probes or thermometers which are too large may cause faulty measurements because of substantial heat removal, inertia, and because their temperature sensitivity is not localised on a point but spread over a larger surface. Use measuring instruments with an immersion probe, having a minimum precision of 0.3°C and a resolution of 0.1°C.

After setting the temperature, wait at least 1 minute before measuring to allow temperature stabilization of the double-barrelled hose and handle.

Measure and compare with "first value measured" of unit leakage current according to VDE 0751 (measured during operation).  The "value measured first" may not be exceeded by more than 50%. Document and record the evaluation and tests according to VDE 0751.

Decalcification  If the tap water in the area, where the unit is used, is known for mineral precipitation, preventive decalcification should

be carried out:

• • • • • • • •

Close water tap. If applicable, dismantle filter when mounted vertically at water tap. Unscrew screwed glass of filter. Fill screwed glass with approx. 100 ml of decalcifier on acetic / citric, or lactic acid base (for inst. Citrosteril, by Fresenius). Screw glass on again. Install filter vertically again, if applicable. Open water tap again. Switch on the unit.  Decalcification takes place automatically in the thermal process for reducing bacterial count. After the unit has been in this mode for 5 minutes the water passages have been decalcified and cleaned, and also sufficiently flushed. The Aquamatic TM II is again fully ready for operation. When water passages are heavily calcified, a modified procedure may become necessary, with a prolonged reaction period for the decalcifier.

 Recommendation: Calcification safety device 502.0995.0.

Replacement of filter

 When the filter cartridge is very dirty (dark colour) the filter

cartridge is to be exchanged as follows: • Close water tap of supply. • Switch on unit to reduce pressure in the filter body. • Switch off unit after appearance of "F 1". • Unscrew Plexiglass cup (, fig. 7) from filter body (, fig. 7) by turning anti-clockwise. • Extract filter cartridge (, fig. 7) and replace by new one (Art.No. 502.0891.0).

 The filter element must not come into contact with

contaminated objects in order to prevent the ingress of germs into the water system.
