2. Installation Wall Mounting Select a suitable location for the final positioning of the heater, ensuring the spray will discharge into a suitable basin/sink during use. To mount the heater first remove the front cover by unscrewing the two pairs of screws located at the top and bottom of the heater. - Page 4 Plumbing Final connection to the water supply should be made by 15mm copper pipe compression fitting to the cold (right hand) inlet side of the heater. Do not carry out soldering close to the heater as heat transfer can cause damage to the unit.
- Page 5 Electrical • A cable with a minimum size of 1.5mm should be used for the fixed wiring of the heater. • Electrical supply should be capable of isolation via double poled switch rated for 13 amps. • The heater must be earthed. Select the entry point for the cable;...

In the case of a manual reset event, the cause should be established before continuing usage. A low flow or obstruction in the spray head is the most likely cause and this problem should be rectified prior to re-using the heater. If in doubt contact Hyco technical support on 01924 225215. - Page 10 Pressure Relief Valve The Wave hand wash unit also incorporates a pressure relief valve. In the event of an over pressure event a small silicone ball will be expelled from the unit which will allow the unit to release the pressure build up. If the valve does operate the reason for the discharge should be established and rectified before replacing the relief valve ball (a common cause can be a scaled up spout head).

Questions and answers
I've just fitted a HW30A, and it does not work when I wave my hand in front, but if if remove the cover whilst still live, it comes on and produces hot water, can you help?
If the Hyco HW30A is not activating when a hand is waved in front of it, possible issues could include:
1. Power supply problem – The unit may not be receiving power due to incorrect wiring or a tripped circuit.
2. Infra-red sensor malfunction – The sensor may be blocked, dirty, or faulty, preventing it from detecting hand movement.
3. Internal flow valve not properly set – If the valve is not fully closed during assembly, the control may not function correctly.
4. Cover or temperature control dial misalignment – If the dial is not properly engaged with the valve spindle, the unit may not operate correctly.
Check electrical connections, clean the sensor, and verify the correct installation of the cover and control dial.
