3.0 INSTALLATION
This appliance must be earthed. It is suitable for a.c. supply only. Electrical
installation must be carried out by a competent electrician and be in accordance
with the latest I.E.E. wiring regulations.
3.1 LOCATION
3.1.1 Select a suitable site such that
a) there is enough clearance under the heater to allow removal of the element plate.
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.
3.1.2 Mark the position of the xing holes (as shown in Figure 01).
3.1.3 Drill and plug the hole positions.
3.1.4 Screw in the top two screws leaving heads 3mm from the wall.
3.1.5 Hang the heater on the two top screws.
3.1.6 Screw in bottom screw to secure the heater.
3.2 PLUMBING
3.2.1 The heater is designed to be connected directly to the mains via the valve
provided or Heatrae Sadia open outlet taps.
3.2.2 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.
3.2.3 The inlet must always be on the right.
3.2.4 In both undersink and oversink installations the inlet and outlet connections
must remain beneath the heater.
3.2.5 The outlet of this water heater acts as a vent and must not be blocked or
restricted in any way.
3.2.6 Connect the control valve supplied to the inlet pipe on the water heater.
3.2.7 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).
3.2.8 Push the outlet spout directly into the outlet tting.
3.2.9 To remove outlet spout, push white ring upwards towards body of tting
and pull spout downwards.
3.2.10 The installation must be carried out in accordance with the relevant
requirements of:
• The appropriate Building Regulations either The Building Regulations, The
Building Regulations (Scotland) or Building Regulations (Northern Ireland).
• The Water Fittings Regulations or Water Byelaws in Scotland.
3.3 ELECTRICAL
Disconnect the electrical supply before removing the cover. Installation must be in
accordance with the current local wiring regulations. A double pole isolating switch,
with a contact separation of at least 3mm in both poles, should be incorporated
in the electrical supply. The supply should be fused 13 Amp. The nominal cross
sectional area of the supply cable must be 1.5mm2 minimum.
3.3.1 Remove terminal cover.

3.3.2 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.
3.3.3 Loosen the top screws securing the cable grip.
3.3.4 Pass the cable underneath the cable grip and through the top moulding.
3.3.5 Make the connections to the terminal block as follows:
BROWN or RED to terminal marked “L”
BLUE or BLACK to terminal marked “N”
GREEN/YELLOW or GREEN wire to terminal marked
3.3.6 Secure the cable in the cable grip by tightening the two screws.
3.3.7 Set the adjustable thermostat by rotating the control to the required
temperature.
3.3.8 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.
3.3.9 Replace terminal cover.

4.0 COMMISSIONING
DO NOT SWITCH ON HEATER UNTIL IT IS FILLED WITH WATER
4.1 Fill with water by opening valve and leaving open until a full bore of water
ows from the outlet.
4.2 Close valve and switch on water heater at double pole isolating switch. The
heater will heat the water to the temperature set on the thermostat.
4.3 Check water is heating correctly.
7 litre 3.0kW - after 10 mins water temperature will increase by 60°C t
7 litre 1.0kW - after 10 mins water temperature will increase by 20°C
15 litre 3.0kW- after 10 mins water temperature will increase by 28°C
4.4 Pass instruction leaet to user and draw their 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 is faulty and
overtightening of the valve can result in damage.
