	Installation Instructions - "Touch pad" & "Sensor" Taps and Showers

The standard unit for “Taps & Showers” comprises one 24 volt AC Adapter (1A), one Touch Plate Controller, one 24 volt 13mm or 10mm Solenoid Valve and one 2m length of Figure Eight cable.

PLACEMENT OF THE TOUCH PLATE CONTROL UNIT:

The Touch Plate incorporates the System Controller and can be placed in any convenient location. There are two adjustment Rotary Switches on the Control Module that allows you to adjust the length of time and lockout of the Solenoid Valve stays open for. Refer to table below for settings:

TIMING AND LOCKOUT ADJUSTMENT TABLE:

The connections to the Touch Plate Controller are as follows: Power supply to “AC IN” screw connector. Solenoid Valve to “Valve” screw connector.

NOTE:

As the input and output point are both A.C. the connectors are not polarity conscious.
Ensure that adequate Silicon is used to ensure water does not run down the back of the stainless steel backing plate when cleaning is being carried out.

POWER SUPPLY:
A standard mains power point is required for each Control Module. The AC Adapter is connected to the Control Module at the positions marked “ACIN” on the unit. Do not turn the power on until the installation procedures have been completed.

WIRING:
The wiring used to and from the control unit is standard “figure 8” cable and is widely available from electrical wholesalers and retailers.

All wiring should be in conduit.

EARTHING:
An Earthing Stud is provided adjacent to the Valve and AC IN connectors for grounding the metal parts of the unit.

SOLENOID VALVE:

The Solenoid Valve should be fitted to the water line as close to the spout as possible – but concealed to prevent vandalism. Stop-cock or isolation valves should be installed for each unit to allow for removal of each unit should it be required.
It is recommended that flow controls be inserted into the spouts – 6 litres per min for Taps and 9 or 12 litres per min for showers
Solenoid Valves must be fitted with disconnection unions on both sides of the Valve for maintenance purposes.

Torx Slot/Drive heads are used to open the Valves to clean – Available from Blackwoods

IN-LINE FILTER:
It is recommended that an in-line filter be placed on the line to prevent water contaminants from entering the solenoid valve and unseating the valves diaphragm.

SET PRESSURE VALVE:
A Set Pressure Valve may be required if the water pressure is high.

PLEASE NOTE:
Ensure that the water line is flushed of any rubbish before the Solenoid Valves are connected to ensure that nothing gets caught under the seat of the Solenoid Valves to stop them closing correctly. Should they fail to close correctly the Valvesshould be checked and cleaned.
