1 IMPORTANT PRE-INSTALLATION NOTES
Connection to an interrupted power supply intended to stop electrical consumption in an unused facil-
ity, may adversely affect this sensor product and is therefore not recommended.
Each time the power supply is reinstated the product briey enters reprogramming mode.
During reprogramming mode, any interaction (passive or active) with the product may alter the sensor
settings in respect to range and / or run duration.
Nosignicantsavingswillbeachievedbyconnectiontoaninterruptedsupply.Theseproductsarein-
trinsically economical in terms of both water and electrical energy and will shut down in the event of a
sensor being obstructed.
SENSOR PROTECTIVE COVER
This product is supplied with the sensor lens covered over with a black-out material.
DO NOT REMOVE this lens cover until the product
installation has been completed & then wait for at least 20

The ttings covered by this installation and maintenance instruction should be installed in
accordance with the water regulations published in 1999*, therefore Armitage Shanks would
strongly recommend that these ttings are installed by a professional installer
*A guide to the Water Supply (Water Fittings) Regulations 1999 and the Water Byelaws 2000, Scotland is published by WRAS (Water
Regulations Advisory Scheme) Fern Close, Pen-y-Fan Industrial Estate, Oakdale, Newport, NP11 3EH.
ISBN 0-9539708-0-9
This product is designed to be supplied with water at a pre-mixed temperature or with cold water only.
In order to maintain water quality, the hot supply should be stored & distributed at a temperature greater
than 55°C.
Use of an appropriate temperature reduction device (e.g. tee pattern thermostat) is recommended to
ensure delivery of safe hot water temperatures from the shower head.

soristriggeredbysomethingreective(normallytheuser’shandmovement)
in the Sensing Region.
User should stand under shower outlet
& move a hand aross the sensor within a
100mm or so. The shower will turn on &
run for a default run-time of 30 seconds
… then turn off.
If user moves hand across the sensor
whilst water is running, the shower will turn
off (toggle On-Off).
The default run time & sensor range can
be adjusted, see section 7.
The sensor is factory set to timed flow
mode.

(SENSOR SHOULD NOT BE LOCATED DIRECTLY OPPOSITE A WALL MIRROR.)
The sensing range & run time can both be adjusted.
Default factory settings are 100mm range & 30 seconds run time.
Run time of 30 is considered satisfactory for most applications. Too short a run time
 willincreasethefrequencyoftheuser’sinteractionswithsensor.
A long run time can increase water consumption.
This can be done in one of two ways: (A) manually or by (B) using a remote sensor programming unit
with some manual actions.
