1 USER INSTRUCTIONS
Control dial
Reset button
Control dial
Reset button
This appliance is not intended for use by persons (including children) with reduced physical,
sensory or mental capabilities, or lack of experience and knowledge, unless they have been
given supervision or instruction concerning use of the appliance by a person responsible for
their safety. Children should be supervised to ensure that they do not play with the appliance.
The temperature of the hot water can be adjusted, and should ideally be set to 60°C (the
position indicated in the diagram below). A higher setting uses more energy and more fuel.
When a hot tap is turned on there may be a short surge of water – this is quite normal with
unvented systems and does not mean there is a fault. When you first fill a basin the water may
sometimes appear milky. This is due to air bubbles in the water which will clear very quickly.
1.1 Cylinder Thermostat
All cylinders (except Direct models) are fitted with one or more
cylinder thermostats to control the heat input to the cylinder from a
remote heat source, such as a boiler, heat pump or solar thermal
installation. The temperature of each cylinder thermostat is
adjustable between nominally 40°C and 70°C. Turn the control
knob clockwise to increase temperature, and anticlockwise to
decrease.
Each cylinder thermostat has a built-in manually reset safety
thermostat which will ‘lock out’ in the event of the cylinder
overheating and which will need to be reset in order to restore
operation. Remove the lock-out cover and depress the red button
to reset.
1.2 Immersion Thermostat
Isolate ALL electrical supplies to the appliance before removing the immersion cover.
All cylinders are supplied with one or more immersion heaters to
allow the cylinder to be heated electrically. Each immersion
heater has an immersion thermostat, the temperature of which is
adjustable between nominally 10°C and 70°C. Remove the
immersion heater cover and turn the control dial anticlockwise to
increase temperature, and clockwise to decrease.
Each immersion thermostat also has a built-in manually reset
safety thermostat which will ‘lock out’ in the event of the cylinder
overheating and which will need to be reset in order to restore
operation. Remove the immersion heater cover and depress the
red button to reset.
1.3 Discharge
If cold/warm water is discharged from the cylinder via the tundish, call your installer.
The pressure relief valves should be operated regularly to remove lime deposits and to verify
they are not blocked.
If very hot water is discharged, immediately switch off ALL heat sources (which may include
boilers, heat pumps, solar thermal systems and immersion heaters), isolate their electrical
supplies and call your installer.

2 INSTALLATION REQUIREMENTS
Prior to installing this unvented hot water cylinder, please confirm that:
a) The mains water supply is capable of achieving a minimum flow rate of 20 litres per
minute at a minimum dynamic pressure of 1.5 bar at all times. If this performance
cannot be achieved the installation of an unvented cylinder may not be suitable.
b) The maximum mains supply pressure at any time does not exceed 12 bar. If this is the
case an additional ‘special’ pressure reducing valve (not supplied) may be required.
c) The mains water supply is from a public source (i.e. not from a private borehole) and that
the hardness of the water is less than 200 mg/litre. Where hardness in excess of 200
mg/litre is experienced, a suitable and effective hard water treatment must be installed.
d) All circuits supplying heat to the heat exchanger coils of any cylinder (not applicable to
direct cylinders) are fully pumped (gravity circulation is NOT suitable).
e) The pipework supplying the hot water taps is capable of withstanding a maximum
pressure of 7 bar at a temperature of 90°C.
This appliance must be installed vertically (not on its side) in a frost-free indoor location.
The installation of this appliance is subject to the Building Regulations:
England & Wales Building Regulation G3
Scotland Technical Standard P3
Northern Ireland Building Regulations P5
Republic of Ireland Technical Guidance Document Part L
The appliance and installation must be commissioned as described herein and the Guarantee
Registration section of the separate Cylinder Passport completed and returned to the
manufacturer.
FAILURE TO COMMISSION, REGISTER AND ANNUALLY SERVICE THIS
PRODUCT WILL INVALIDATE ALL GUARANTEES
Under no circumstances must the factory fitted temperature & pressure relief valve be
removed. Removal of the valve would create an extremely dangerous situation and
would invalidate all guarantees.
