1 USER INSTRUCTIONS
1.1 General Information
Your hot water cylinder has been designed to give many years of trouble free service and is
made from hygienic, high grade, duplex stainless steel.
The flow temperature of the hot water can be adjusted to your requirements, and should ideally
be set to 60°C. Choosing a higher temperature increases the energy required to heat the
cylinder and maintain its temperature, costing more in fuel.
1.2 Cylinder Thermostat
All cylinders are fitted with 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.
1.3 Immersion Thermostat
Isolate ALL electrical supplies to the appliance before removing the immersion cover.
All cylinders are supplied with an immersion heater to allow the
cylinder to be heated electrically. The 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.
The 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.
2 INSTALLATION REQUIREMENTS
The cylinder must be installed vertically (not on its side) in a frost-free indoor location.
The cylinder must be open vented i.e. supplied via an open vented expansion tank and have a
vertical vent pipe of at least 19mm internal diameter.
The mains water supply must be from a public source (i.e. not from a private borehole) and the
hardness of the water must be 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.
All 22mm coils must be fully pumped – gravity circulation is NOT suitable for the 22mm coils.
Gravity circulation may only be used on the 28mm coil(s).
