Switch On
Temperature and ow settings will be same as when last used.
After a short period, display will dim to help extend battery life.
Shower will not run continuously for more than 30 minutes before stopping
automatically (5 minutes when “ECO” function is set to “on”).
When “Warm-Up” function is “on”, there will be a short delay (5 seconds) before
water ows from shower.
USING THE SHOWER
Press “ ” to start shower.

Adjust Temperature
Adjust Flow
Press “ ” or “ ” to adjust ow. Showering ow level appears on display in
segments.
Adjust Temperature
While shower is running, press “ + ” or “ - ” to adjust temperature.
The temperature shown on the display is in degree Celsius (°C) and indicates the
user requested temperature.
Note: This temperature is measured inside the mixing valve and therefore will differ
from that actually being delivered at the outlet. The amount the temperature differs
by will depend on site conditions, ambient room temperatures and length of outlet
pipe runs.

Switch Off
Press “ ” to stop shower.
After the shower has stopped, the display will turn off automatically.
Note: It is normal for all shower outlets to continue to expel water for a short period
of time after use. It is not uncommon for larger deluge shower heads, particularly
those connected to long outlet pipe runs and therefore holding large volumes of
water, to drain down water several hours after use due to the changes in the ambient
temperature. We would therefore recommend that all water outlets are kept enclosed
within the water catchment area.
