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
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 disco

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.

Usage

If the heater is used regularly it is recommended that it is left on at all times.
The thick insulation ensures economic running costs.
Allow the heater to fill with water before switching on the electricity.
This will avoid the heating element becoming too hot, causing the one-shot safety thermal fuse to operate.

The four settings indicated by the thermostat are: -

III This gives very hot water, which can be mixed with cold water to produce quantities of usable water greater than

the actual capacity of the heater.

II This setting will deliver, direct water suitable for washing up.
I This setting will deliver, direct, water suitable for hand washing.

• This setting will maintain the water in the heater just above freezing point if the heater is to be left unattended whilst

subject to freezing conditions. The electricity must be left on for this facility.

Water expands when heated, thus during the initial heating of cold water admitted to the heater, drips from the outlet
spout may occur.

If it is required that the adjustments of the thermostat is not available to the users of the heater, then after first
establishing that the temperature is as required, the knob may be removed and the blanking grommet (supplied free with
heater) inserted in the hole.
