INTRODUCTION

Thank you for purchasing a quality Redring Active 350S Electric Shower manufactured in England.
To enjoy your new shower at its best, please take time to read this manual thoroughly, and having
done so, keep it handy for future reference.

The Redring Active 350S is an electric shower incorporating our “Smart Technology” and a unique
dual control combining on/off, power select and flow/temperature control.
Your shower is designed to stabilise temperature
These can result from toilets being flushed or taps being turned on and off.
When this happens your showering temperature will be held within a controlled band, provided that
the minimum pressure required by the shower is maintained (see “Effect of Other Water Devices”).

If you experience any difficulty with the installation or operation of your new

shower, then please refer to the “What to do if things go wrong” section in this

manual before contacting us.

IMPORTANT SAFETY INFORMATION

1. Your shower has been designed for convenience, economy and safety of use, provided that it is
installed, used and maintained in good working order and in accordance with our instructions and
recommendations.

2. All wiring and installation must be supervised by a suitably qualified person.

3. THIS APPLIANCE MUST BE EARTHED.

4. The installation must be in accordance with the current edition of BS.7671 (the “IEE Wiring
Regulations”) and “Part P” of the “Building Regulations” in force at the time of installation.

Installations outside the United Kingdom must also conform to any local regulations in effect.

This appliance is intended to be permanently connected to the fixed electrical wiring of the mains
supply with its own dedicated supply.

5. This appliance must NOT be fitted where it may be subjected to freezing conditions

6. DO NOT switch the appliance on if you suspect it of being frozen.
Wait until you are sure it has thawed out.

7. DO NOT fit any sort of tap or control on the appliance outlet. The appliance is designed to have
an open outlet and should only be used with “Redring” recommended fittings.

8. Take care to avoid restricting the outlet of the pressure relief device. If water leaks from the
pressure relief device, maintenance will be required before the appliance can be safely used.

9. Isolate the mains electrical and water supply before removing the front cover of the appliance.

This reduces the temperature of the water in the tank for the next user.

1. Ensure the electricity and water are turned on to the unit.

HOW TO USE YOUR ACTIVE 350S SHOWER (DETAILED)

2. Your shower has 3 power settings selected by turning outer

knob “A”.
The most popular is “ (high)”.
There are also options for a “ (medium)”
or “ (cold)” shower (see notes 8 and 9).

For this example turn outer knob “A” to “ (high) ”
and set inner knob “B” to “12 o’clock”.

3. The water will flow and the neon light will glow brightly.

4. Allow about 20 seconds for the temperature of the water to

stabilise.

IF WATER IS TOO COLD

Turn inner knob “B” clockwise in the

direction of the “red arrows” to “1 o’clock”
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.

If after turning fully clockwise water is still too
cold, set shower pattern on shower handset
to outer or inner pattern only.

Turn inner knob “B” anti-clockwise in the
direction of the “blue arrows” to “11 o’clock”
and continue turning anti-clockwise until you
get the water temperature of your l

Wait 20 seconds after each adjustment for
the water temperature to stabilise.

If after turning fully anti-clockwise, water is still
too hot, adjust outer knob “A” to “ (medium)”
setting and re-adjust as above.

Water flow will be reduced on this setting.

IF WATER IS TOO HOT

5. Once a temperature setting to your liking has been achieved, inner knob “B” 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”).

6. When you have finished showering, turn outer knob “A” anti-clockwise to the “ (stop)” position.

Water will continue to flow for approximately 7 seconds before switching off.

Switch off the electricity at the ceiling switch or local isolator.

7. The “ (medium)” setting of outer 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 inner knob “B” must be re-adjusted.

8. The “ (cold)” setting of outer knob “A” will supply water without any heating, and the neon light

will go out.

9. Your shower is designed to stabilise temperature changes caused by water pressure fluctuations

(see “Effect of Other Water Devices on Incoming Water Supply”).

10. Note that inner knob “B” IS NOT A TAP and does not turn the water off.

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 SAFELY
USED.

WARNING: CONSIDERATION SHOULD BE GIVEN TO SUPERVISING THE YOUNG, ELDERLY

AND THE INFIRM WHILST THEY USE THIS SHOWER.

Your shower requires a minimum operating pressure of 69kPa (0.7 bar, 10 psi).

nts, resulting in a cold shower.

HOW YOUR ACTIVE 350S SHOWER WORKS

1. Water is heated instantaneously as it flows over the

heating elements in the copper cylinder (diagram 2).

2. The heaters are only switched on when sufficient

water is flowing.
This is done automatically with a switch which works
on water pressure and is indicated by the neon light
illuminating depending on the power selected by
outer knob “A”.

3. The water is turned on and off by the solenoid valve

built into the shower.
This is switched on when outer knob “A” is clicked
clockwise.

4. The flow of water is automatically held at the level

set by the user even though the supply pressure
may vary (see “Effect of Other Water Devices on
Incoming Water Supply”).

5. If the water supply falls below a set limit, the pressure switch will operate and switch off the

power to the elements. This is indicated by the neon light going out (see “Effect of Other Water
Devices on Incoming Water Supply”).

6. As a further safeguard, a thermal cut-out switches the power off if the water temperature

climbs above the set limit. This cut-out, which gives an audible click, may also operate due to
residual heat when the shower is switched off.
It will reset itself if water is run through the shower for 10 to 20 seconds.

7. The pressure relief device is to safeguard against abnormal pressure conditions.

Effect of Seasonal Incoming Water Temperature Changes

The required water temperature is achieved by adjusting the rate of water flow.
Diagram 3 shows the principle involved in relating temperature rise to flow rate.
The higher the water rate the lower the temperature and vice versa.
The temperature of the water supplied from the mains can vary considerably
th
This means that in the winter, flow rate will be less than in the summer to
achieve the same outlet tempera

In some summer conditions, the “ (medium)” power setting may give adequate hot water.
In some winter conditions, it may be necessary to select the inner or outer spray pattern only of
your shower handset. This will ensure correct operation of the shower with a slightly lower flow rate.

Effect of Other Water Devices on Incoming Water Supply

Your shower is designed to stabilise temperature changes caused by water pressure
fluctuations. These can result from toilets being flushed or taps being turned on and off.
When this happens your showering temperature will be held within a controlled band, provided that
the minimum pressure required by the shower is maintained.

At pressures above 69kPa (0.7 bar, 10 psi) it will minimise temperature fluctuations as detailed
above. If the water pressure falls below 69kPa (0.7 bar, 10 psi) it is likely that the pressure switch
will turn off the power to the heating eleme
This will be indicated by the neon light going out.
