The valve will require periodical servicing and cleaning, please 
contact manufacturer for servicing.

Do not attempt to dismantle the valve if you are unfamiliar with 
electronic solenoid valves.

- Check all connections (shown in Fig 2).
- Check fuse (Mains/PSU model only).
- Voltage too low. Check tap input voltage (PSU output voltage - 6v 
DC).
- Voltage too low. Replace battery, CRP2 or DL223A Lithium Cell 
only.
- Check / Clean all connectors (shown in Fig 3). 
- Check for cable damage. 
- For Mains/PSU models, disconnect PSU and reconnect after 30 
seconds 
- Check water is turned on.  
- Check the solenoid valve is fitted correctly. 
- Check valve operation. 
- Check for dirt or debris in the solenoid valve. 
- Water pressure is too high.

14.1 Tap operates in reverse

 (Water runs when hand is moved away from sensing area and 
stops when returned to sensing area). Reversed valve polarity 
(contact manufacturer)

14.2 Tap operates intermittently

- Clean sensor lens (with nonabrasive materials only).
- Tap may be installed too close to an R.F. interference source).
- Tap may be installed too close to very bright lighting / highly 
reflective surfaces.
- Water pressure too low for valve to operate reliably (minimum 0.5 
BAR

14.3 Optional Parts

AT00 - 033 / 1m PSU cable extension
AT00 - 034 / 2m PSU cable extension
AT00 - 035 / 3m PSU cable extension

Warranty

The tap kit is guaranteed for 5 years from purchase against 
defective material and assembly.

13.1 General

In the absence of any other instruction or guidance on determining 
the appropriate frequency of in-service testing, the following 
procedure may be used:

a)  6-8 weeks after commissioning carry out the “In-Service Tests”

b)  12-15 weeks after commissioning carry out the “In Service Tests”

The results of the above tests may presence several possibilities:

a)   If no significant changes (e.g. 1 K) in mixed water temperatures 

are recorded between commissioning and 6 to 8 week 
testing, or between commissioning and 12-15 week testing the 
next in-service test can be deferred to 24 to 28 weeks after 
commissioning. 

b)   If small changes (e.g. 1 to 2 K) in mixed water temperatures 

are recorded in only one of these periods,  necessitating 
adjustment of the mixed water temperature, then the next 
in-service test can be deferred to 24 to 28 weeks after 
commissioning. 

c)   If small changes (e.g. 1 to 2 K) in mixed water temperatures are 

recorded in both of these periods, necessitating adjustment 
of the mixed water temperature, then the next in-service test 
should be carried out at 18 to 21 weeks after commissioning. 

d)   If significant changes (e.g. > 2 K) in mixed water temperatures 

are recorded in either of these periods, necessitating service 

work, then the next in-service test should be carried out at 18 
to 21 weeks after commissioning.

The general principle to be observed after the first 2 or 3 in-service 
tests is that the intervals of future tests must be set to those which 
previous tests have shown can be achieved, with no more than a 
small change in mixed water temperature.

Fault Finding

13.2 Tap will not operate at all

- Check water is turned on. 
- Check hot and cold feed connected correctly 
- Check filters for debris
