INSTALLATION
1. The cold water inlet must always be on the right.
2. In both under and oversink installations the inlet and outlet connections must remain
beneath the heater. (See Figure 3 for undersink installation).
3. The outlet of this water heater acts as a vent and must not be blocked or restricted in
any way.
4. Only Heatstore open outlet taps and spouts should be used with this water heater. A
full range is available, please consult either your distributor or Heatstore for further
information.
5. The installation must be carried out in accordance with the relevant requirements
of:
• The appropriate Building Regulations either The Building Regulations, The Build
ing Regulations (Scotland) or Building Regulations (Northern Ireland).
• The Water Fittings Regulations or Water Byelaws in Scotland.
POSITIONING THE WATER HEATER
1. Select a suitable site but check that:
a) There is enough clearance under the heater to allow removal of the element plate
(210mm).
b) When using the outlet spout, it will swing over the sink (or sinks) to be supplied.
c) There are no hidden services where the wall is to be drilled.
2. Mark the position of the xing holes (as shown in Figure 4).
3. Drill and plug the hole positions.
4. Screw in the top two screws leaving head 3mm from the wall.
5. Hang the heater on the two top screws.
6. Screw in bottom screw to secure heater.
PLUMBING REQUIREMENTS
The water heater is designed to be connected directly to the mains via the valve
provided or Heatstore open outlet tap ttings.
It is recommended that a WRAS listed isolating valve (not supplied) be tted in the
water supply pipe to the heater to allow for servicing.
SPOUT AND VALVE
1. Connect the control valve supplied to the inlet pipe on the water heater.
2. Connect the cold water main to the control valve using 15mm outside diameter pipe
(either copper to BS 2871 or stainless steel to BS 4127).
3. Push the outlet spout directly into the outlet tting.
TO REMOVE OUTLET SPOUT
1. Remove terminal cover.
1. Push grey ring upwards towards body of tting.
2. Pull spout downwards.

OPEN OUTLET TAP FITTING
1. Ensure electricity supply is switched off.
2. Remove terminal cover (using a at bladed screwdriver to relieve snaps located
towards the front of the terminal cover either side).
3.Plumb from the open outlet tap tting using 15mm outside diameter copper pipe to
the 15x15mm john guest tting in the water heater. The tap set will have its own instal-
lation instructions.
ELECTRICAL REQUIREMENTS (REFER TO FIGURE 2 - WIRING
DIAGRAM).
•WARNING: THIS APPLIANCE MUST BE EARTHED.
•CONNECT ONLY TO 230 / 240V AC SUPPLY.
•NOMINAL CROSS SECTION OF SUPPLY CABLE MUST BE AT LEAST
15mm2.
•A DOUBLE POLE ISOLATING SWITCH WITH A CONTACT SEPARATION OF
AT LEAST 3mm IN EACH POLE MUST BE INCORPORATED IN THE
SUPPLY.
•ELECTRICAL INSTALLATION MUST CONFORM TO THE CURRENT I.E.E.
WIRING REGULATIONS.
1. Remove terminal cover (as described above).
2. Strip the outer sheath and insulation on the cable to the required lengths, making
sure the outer sheath of the cable will be held in the cable grip when the connections
are made.
3. Loosen the top screws securing the bar at the cable grip.
4. Pass the cable through the cable grip.
5. Make the connections to the terminal block as follows:
-Live (brown or red wire) to terminal marked “L”
-Neutral (blue or black wire) to terminal marked “N”
-Earth (green or green/yellow wire) to terminal marked
6. Secure the cable in the cable grip by tightening the two screws.
7. Set the adjustable thermostat by rotating the control to the required temperature, the
reading being taken from the top of the dial. It is recommended that it is set to
lowest acceptable temperature to meet user requirements. This will minimise the
risk of scalding and reduce the level of scaling in hard water areas.
8. Replace terminal cover.
OPERATION
DO NOT SWITCH ON HEATER UNTIL IT IS FILLED WITH WATER
1. Fill with water by opening valve/tap and leaving open until a full bore of water
ows from the outlet.
2. Close valve and switch on water heater at double pole isolating switch. The heater
will heat water to the temperature set on the thermostat.
3. Check water is heating correctly.
7 litre 1.2kW - after 10 mins water temperature will increase by 20°C

5
7 litre 3kW - after 10 mins water temperature will increase by 50°C
10 litre 3kW - after 10 mins water temperature will increase by 35°C
4. Pass instruction leaet to user and draw his attention to the following two
statements.
a) DO NOT USE HEATER IF THE WATER IS THOUGHT TO BE FROZEN
Switch off immediately at the isolating switch if the water does not ow freely.
Any damage resulting from freezing will not be covered by the guarantee.
b) DURING HEATING THE SPOUT/TAP WILL DRIP
This is due to the expansion of water inside the heater and is normal for heaters of
this type. It does not indicate that the valve/tap is faulty and overtightening of the
valve/tap can result in damage.
