Thank you for purchasing a quality 
Redring Active 320S Electric Shower

To enjoy your new shower at its best, please take time to read this manual thoroughly to

The 
Redring Active 320S

“Smart Technology”
 and a unique 
dual control combining on/off, power select and flow/temperature control. 
Your shower is designed to stabilise temperature chan
g
es 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 (see “Effect of Other Water Devices”). 
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.

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.
