1 USER INSTRUCTIONS
1.1 General Information
Your unvented hot water cylinder has been designed to give many years of
trouble free service and is made from hygienic, high grade, duplex stainless steel.
When a hot tap is opened 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 tiny air bubbles
in the water which will clear very quickly.
1.2 Cylinder Thermostat
(not applicable to Direct models)
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 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 before removing the immersion cover.
The temperature of each immersion heater 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 need to be reset in order
to restore operation. Remove the immersion heater
cover and depress the red button to reset.
1.4 Discharge
If cold/warm water is discharged from the cylinder via the tundish, call your
installer.
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.
