Thank you for choosing a quality
Redring product manufactured in
Peterborough, England
These instructions should be read in full before commencing the installation.
We recommend that the installation should only be carried out by a suitably qualified person.
The Redring WS7 is an open outlet, thermal storage water heater for use with Redring recommended fittings for one
outlet only. It operates on the displacement principle i.e.; when cold water is admitted into the bottom of the tank, hot
water flows out through the outlet. There are two models: 3kW, which ensures rapid reheating of the water, and a 1kW
unit to suit special electrical requirements.
Fixing
The wall bracket should be securely fixed in
position (see diagram 1). The heater is then hung
on the wall bracket. Further security can be
obtained by marking the position of the extra fixing
holes (see diagram 1) and applying appropriate
wall fixings to these positions.
When the unit is used above the sink with the cold
inlet tap and spout supplied, it is recommended that
these extra fixing positions be used.
The bottom of the heater should be approximately
350mm above the top of the sink.
The outlet should be at least 13mm above the
maximum possible water level for any
appliance that is to be filled from the heater.
Water Connection
(See diagram 4 for suggested installation plan)
Oversink (Diagram 2a)
When using the tap and spout as supplied, the cold
water connection is made directly to the 15mm
compressions fitting at the rear of the cold inlet tap.
Ensure that the water flow is in line with the flow direction arrow moulded on the cold inlet tap.
Undersink (Diagram 2b)
If the unit is to be mounted below sink level, it should be connected to the special open outlet Monoblock Mixer Tap
recommended by Applied Energy Products Limited (see page 3).
The economic performance of the heater will be enhanced by lagging the hot water pipe from the heater to the outlet.
Oversink and Undersink Installation
Before final assembly of the tap the appropriate restrictor insert must be selected and fitted into the end of the cold inlet
pipe on the heater (see Table A). The correct insert will ensure that the flow rate of water through the heater is at an
optimum to prevent undue mixing of the incoming cold water with the stored hot water, as well as avoiding any
unnecessary pressure within the tank.
Electrical Connection
The installation must be in accordance with the current BS.7671 (IEE Wiring Regulations) and/or local regulations, and
“Part P” of the Building Regulations.
1. The heater is suitable for 240/230V single phase A.C supply.
2. The live (brown) and neutral (blue) wires must be connected to the designated positions in the terminal block and the
earth (green/yellow) to the earth
position.
3. WARNING: THIS APPLIANCE MUST BE EARTHED
4. The mains cable should be prepared as shown (see diagram 3)
5. A means for disconnection in all poles must be incorporated in the fixed wiring in accordance with the wiring rules.
6. The cable should be heat resisting 3-Core flexible PVC of 0.75mm² for the 1kW model and 1.25mm² minimum for the
3kW model.
7. NOTE – THE APPLIANCE MUST BE FILLED WITH WATER BEFORE POWER IS SWITCHED ON.
Suggested Installation Plan
Draining the Tank
If it is required to drain the tank, this can be effected by undoing the screw in the base plate of the heater (see “Tank
Drain” diagram 2), and catching the water in an appropriate vessel.
The heater must be disconnected from the electrical supply before commencing this operation.
If the unit fails to heat water
1. Check that the mains fuses are not blown and that the mains supply is switched is switched on.
2. Check that the cold water supply is on.
3. Check that the outlet has not been blocked in any way.
If the fault persists: -
Contact the dealer from whom you purchased the appliance or the installation engineer.
You can also call the Technical Advisory Helpline on 08709 000430
Installation Engineer Note:
The most likely reason for no heated water is an open circuit thermal fuse. See label on front insulation for details.
This can be caused at initial commissioning if the heating element is energized with no water in the tank.
Alternatively, it may be due to a back siphonage in the cold water supply caused by a break or disconnection.
If you feel that your installation may suffer from a water failure, we recommend the fitting of a non-return water check
valve.
