fitting flow Sensor(s)

Depending on the installation install 1 or 2 filters and sensors to the shower water feed. Install the filter

(Y-Pattern filter) in the correct flow orientation to the shower water supply line and then fit the flow sensor

between the filter and the shower.

Confirm shower water supply pipework is flushed before connecting to the flow sensor via the filter.

electric showers have one water supply line, cold water. fit one filter and flow Sensor to this line. Mixer

showers have two supply lines, hot and cold water. fit one filter and flow Sensor to each supply line.

Double check direction of the flow arrow moulded on the sensor casing is in the correct orientation

with the flow of water. allow enough distance so that the sensors are easily accessible. ensure all cable

connections are accessible and in a dry location. Fit sensor using an approved liquid based thread sealant

suitable for nylon threads. Connect the sensor tail cable from the flow sensor to the pump sensor cable

(see page 12). Do not tile over the flow sensors and filters and ensure they are accessible for service and

maintenance purposes. If possible, avoid installing in a loft space.
