4. Check that the local isolating valve is fully open.
5. Check the inlet filter on the shower is not
blocked (see page 21).
6. If the “o – t” digits flash in the display the unit is

Q. The seven segment display continues to blink on
and off.
A. When making adjustments in temperature
selection the display will change immediately by
one digit warmer or cooler and will continue to
blink until the outlet temperature has reached the
new target. This could take up to 30 seconds.
If the display continues to blink then reduce the
water flow via the rotary flow control knob (in small
stages) until the display stops blinking.
Alternatively reduce temperature by pressing the
cooler (-) push button.
Q. Temperature output is limited.
A. The maximum outlet temperature of the shower
is thermostatically limited to a nominal 47 C under
normal operating conditions. This is for additional
user safety.
