Akw M17 - 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 shower 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 11). Do not tile over the flow sensors and filters and ensure they are accessible for service
and maintenance purposes.
