Check data cable connections are making good
contact and are fully inserted and that there is no
visible damage.
Check that the wiring schematics are as per
installation instructions in the main product
(Aqualisa SmartValve™) installation guide.
For models utilising an adjustable head kit;
disconnect the handset from the hose, lower
the hose into the shower tray or bath. Set the
temperature to fully cold and then start the
shower. As the water starts to flow and increase
in volume gradually turn up the temperature.
If the flow starts to splutter, stop moving the
temperature control until the flow again stabilises,
then continue to move the dial towards the
hottest setting.
Check for debris in the inlet filters of the
Aqualisa SmartValve
TM
connection washer. Must be conducted by a
qualified person. NOTE: The water supplies MUST
be isolated when checking the inlet filters.
Where a flexible hose is fitted, unscrew the
shower hose from the outlet connection and turn
the shower on.
Check with boiler manufacturer for
specification details.
Refer to Setting Water System Mode section
in the main product (Aqualisa SmartValve™)
installation guide. Ensure mode is set to normal
or ECO gravity setting.
During the cooler months the mains water
temperature drops and this will reduce the
performance of combination boilers. Check with
your boiler manufacturer for details.
