IF WATER IS TOO COLD
Turn knob “C” anti-clockwise in the
direction of the “red arrows” until the next
number is displayed in Window “D” and
continue turning anti-clockwise until you get the
water temperature of your liking.
Wait 20 seconds after each adjustment for
the water temperature to stabilise.
The final adjustment may be anywhere on the
scale, even between numbers.
If after turning fully anti-clockwise water is still
too cold, set shower pattern on shower handset
to outer or inner pattern only.
IF WATER IS TOO HOT
Turn knob “C” clockwise in the direction of the
“blue arrows” until the next number is displayed
in Window “D” and continue turning clockwise
until you get the water temperature of your liking.
Wait 20 seconds after each adjustment for the
water temperature to stabilise.
The final adjustment may be anywhere on the
scale, even between numbers.
If after turning fully clockwise, water is still too
hot, adjust knob “A” to “Med (medium)” setting
and re-adjust as above.
Water flow will be reduced on this setting.
1. Ensure the electricity and water are turned on to the unit.
2. Your shower has 2 control knobs (see diagram 1).
Knob “A” controls the 3 power settings.
The most popular is “High”.
There are also options for a “Med (medium)”
or “Cold” shower (see notes 8 and 9).
Knob “C” controls the temperature of the water, and as a
helpful guide the knob position is indicated by a number
being displayed in Window “D”.
On the scale “1” is the coolest, whilst “9” is the hottest.
For this example turn outer knob “A” to “High”
and set knob “C” to display number “5”.
3. Press button “B”. The water will flow and 3 lights will illuminate
to indicate that the selected power rating is “High” (indicated by “High” next to the Indicator Lights).
4. Allow about 20 seconds for the temperature of the water to stabilise.
5. Once a temperature setting to your liking has been achieved, knob “C” will rarely need adjusting. You
must however take into account required adjustments for variations of incoming mains water temperature
between summer and winter (see “Effect of Seasonal Incoming Water Temperature Changes” page 4).
6. When you have finished showering, press button “B” only (the “Med (medium)” light will go out).
Water will continue to flow for up to 7 seconds before switching off.
This reduces the temperature of the water in the tank for the next user.
Switch off the electricity at the ceiling switch or local isolator.
7. The “Med (medium)” setting of knob “A” reduces the power used by the shower giving a cooler shower or
the option of reduced water flow. This option is mainly used for summer usage and if this is used then
knob “C” must be re-adjusted. On this setting 2 lights will illuminate.
8. The “Cold” setting of knob “A” will supply water without any heating, and 1 light will illuminate.
9. Your shower is designed to stabilise temperature changes caused by water pressure fluctuations (see
“Effect of Other Water Devices on Incoming Water Supply” see page 4).
WARNING: DO NOT SWITCH THE SHOWER ON IF YOU SUSPECT IT OF BEING FROZEN.
WAIT UNTIL YOU ARE SURE IT HAS THAWED OUT.
WARNING: DO NOT OPERATE THE SHOWER IF WATER LEAKS FROM THE PRESSURE RELIEF VALVE.
MAINTENANCE IS REQUIRED BEFORE THE SHOWER CAN BE USED.
