Commissioning Checks
As a general precaution and check before installation, always ensure the supply pipework to
the shower has been fully purged with at least 20 litres (2 buckets) of water through it before
the flow sensor or shower water heater are fitted. Any building debris in the water supply to the
shower heater will adversely affect the sensor function and may also damage the shower heater.
Install Pump according to these instructions. Failure to do so will void warranty.
Confirm all push-fit pipes are fully inserted 20mm into fittings.
Brush out all dust, grit and debris
from shower tray
Thoroughly clean out waste
Confirm shower water supply pipework is flushed
before connecting to the shower sensor via the
strainer
Turn on power to Pump
Turn shower on Low Flow and confirm pump
operates after approx 5 secs. Run for 2-3 mins
Set shower to Maximum Flow
Follow the Calibration setting, adjust pump speed
on controller to match maximum shower flow
Adjust RUN-ON and repeat until tray is cleared
and pump stops with minimum RUN-ON
Switch shower OFF.
Pump will RUN-ON
