1. INSTALLATION
1. Inlet must always be on the right.
2. The outlet of this water heater acts as a vent and must not be blocked or restricted
in any way.
3. Use only Santon open outlet spouts.
2. 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 fixing holes (as shown in Fig. Three).
3. Drill and plug the hole positions.
4. Screw in the top two screws leaving heads 3mm from the wall.
5. Hang the heater on the two top screws.
6. Screw in bottom screw to secure heater.
3. PLUMBING REQUIREMENTS
The water heater is designed to be connected directly to the mains via the valve provided.
It is recommended that a WRAS listed isolating valve (not supplied) be fitted in the water
supply pipe to the heater to allow for servicing.
4. REMOVAL AND FITTING OF TERMINAL COVER
To remove the terminal cover use a large flat bladed screwdriver to relieve the snaps located
towards the front of the terminal cover at either side. Gripping the cover at the front, pull
downwards.
To fit the cover, locate the hinge at the back. Slide the snaps into place. Apply pressure to the
front of the cover pushing it backarwds and upwards until it snaps securely in place.
5. 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 EN 1057 or stainless steel to BS 4127).
3. Push the outlet spout directly into the outlet fitting.
TO REMOVE OUTLET SPOUT
1. Remove terminal cover.
2. Push white ring upwards towards body of fitting.

ELECTRICALEMENTS
6. ELECTRICAL REQUIREMENTS (REFER TO FIGURE 2 - WIRING DIAGRAMS)
·WARNING: THIS APPLIANCE MUST BE EARTHED.
·CONNECT ONLYTO 230 / 240VAC SUPPLY.
·NOMINALCROSS SECTION OF SUPPLY CABLE MUST BEAT LEAST 1.5mm2.
·ADOUBLE POLE ISOLATING SWITCH WITHACONTACT SEPARATION OFAT
LEAST3mm IN EACH POLE MUST BE INCORPORATED IN THE SUPPLY.
·ELECTRICALINSTALLATION MUST CONFORM TO THE CURRENT I.E.E. WIRING
REGULATIONS.
1. Remove terminal cover.
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 cable grip.
4. Pass the cable underneath the cable grip and through the top moulding.
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.
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.
7. OPERATION
DO NOT SWITCH ON HEATER UNTIL IT IS FILLED WITH WATER
1. Fill with water by opening valve and leaving open until a full bore of water flows 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 -after10 mins water te
7 litre 3kW - after 10 mins water temperature will increase by 60°C
10 litre 1.2kW - after 10 mins water temperature will increase by 15°C
10 litre 3kW - after 10 mins water temperature will increase by 40°C
4. Pass instruction leaflet 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 flow freely.
Any damage resulting from freezing will not be covered by the guarantee.
b) DURING HEATING THE SPOUT WILLDRIP
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 is faulty and overtightening of the valve can result in damage.
