Troubleshooting - Kohler Rada Intelligent Care MX1 20FEU Produkthandbuch

The function of this DMV (Digital Mixing Valve) is to deliver water consistently at a
desired temperature. This requires that:
1. It is installed, commissioned, operated and maintained in accordance with the
recommendations given in this manual.
2. Periodic attention is given, as necessary, to maintain the product in good functional
order. Recommended guidelines are given in maintenance info on our website
www.radacontrols.com
3. For Type 3 installations, valves are only to be used for applications covered
by their approved designations. Refer to the TMV3 Requirements Manual
(www.radacontrols.com).
4. Using this product outside the specification limits given in this manual can present
potential risk to users.
5. The electrical installation must comply with BS 7671 (UK) and all relevant national
building regulations and any particular regulations and practices specified by the
local electricity supply company.
6. DO NOT fit any form of outlet flow control i.e. trigger handset. Use only
recommended fittings.
The use of the word 'failsafe' to describe the function of any mixing valve is both
incorrect and misleading. This electronic valve incorporates additional shut-off devices
to improve the level of safety however, in keeping with every other mechanism it cannot
be considered as being functionally infallible.
Malfunction of thermostatic mixing valves can be detected by the use of proper
temperature checking and maintenance routines.
Certain types of system can result in the thermostatic mixing valve having excessive
'dead-legs' of pipework. Such systems can disguise the onset of thermostatic mixing
valve malfunction.
Ultimately, the user must exercise due diligence to ensure that the delivery of warm
water is at a stable, safe temperature.
Make sure that the water delivery does not cause splashing or overflow.
