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.

6 MAINTENANCE
Isolate all electrical supplies before removing any components for inspection
or repair, or before draining the cylinder or heat source circuits.
6.1 Regular Maintenance
This appliance must be serviced annually to ensure continued safe operation and
to maintain the guarantee. Servicing must be undertaken by a competent person
i.e. qualified professional.
1 Isolate the mains water supply and open a hot tap. Check the expansion
vessel bladder pre-charge –it should be 3.0 bar.
2 Check the strainer on the inlet group. Clean the strainer if necessary by
unscrewing the pressure reducing valve and withdrawing the strainer.
3 Check and service all hard water treatment devices (if fitted) in
accordance with each device manufacturer’s instructions.
4 Check that all connections are tight and correctly configured.
5 Manually operate (by rotating the knob) both the expansion relief and the
temperature and pressure relief valves to prove the correct function of the
discharge arrangement.
6 Check all joints for leaks and rectify as necessary.
7 Check that all immersion and control thermostats are appropriately set.
8 Activate each heat source to confirm that the system controls function
correctly.
9 Check that, while the cylinder is heating up, no water exits from either the
expansion relief or the temperature and pressure relief valves, and that
the system controls deactivate all heat sources when the cylinder is up to
temperature.
6.2 Replacement Parts
The below listed replacement components are available if required:
Part description Code
Cylinder thermostat WDS6
Immersion c/w stat (1¾”) 3602
