a Risk of scalding and bursts due to inappropriate
alterations!
There is a risk of escaping steam, bursting, and
damage to the system if you make any changes to
the cylinder, control system, supply lines for water
and power (if present), relief valve termination, or
expansion relief valve for the cylinder water.
Do not make any improper changes.
a Risk of scalding!
The output temperature of the draw-off points can
reach 85 °C if the mixing valve is set incorrectly.
- Do not adjust the mixing valve.
- If the output temperature at a draw-off point is too
high or low, Contact an engineer qualified to work on
unvented systems to adjust the temperature.
4.1 adjusting the hot water temperature
The hot water temperature is set to the required value by the
engineer qualified to work on unvented systems during the
cylinder commissioning. If an external controller is installed
for hot water temperature control, you can adjust the hot water
temperature and reheating times using this controller.
For information on making settings, see the operating manual for
the controller.
If no controller for hot water temperature control is installed,
you can set the required hot water temperature on the cylinder
thermostat (2). You can set the reheating times on the installed
hot water timer. Refer to the operating manual for the hot water
timer.
• Set the desired cylinder hot water temperature on the cylinder
thermostat (2).
• For optimum efficiency, choose a setting of 45 °C.
• Use the operating manual for the gas-fired boiler to make sure
that the unit is ready for operation.
We recommend the cylinder is set to 60 °C
periodically, to provide protection against the
proliferation of harmful bacteria.
If you are heating up water for the first time or after a
long switch-off period, the full cylinder performance is
only available following a waiting period.
If the Flurocyl
2
is installed in a cupboard, make sure
that clothing and other objects are not placed on
the cylinder, control devices, pipes, or other system
components.
Always make sure that there is clear access to the
cylinder to enable the use of the hot water thermostat
controller and the thermostat mixer.
4.2 Switching off hot water
• Switch off the immersion heater and the gas-fired boiler (see
the operating manual for the gas-fired boiler) to temporarily
switch off the heating and hot water system.
4.3 frost protection
Risk of damage due to frost!
If the cylinder is placed out of operation for a
relatively long period of time in an unheated room
(e.g. during a winter holiday), the cylinder must be
completely drained.
- Contact an engineer qualified to work on unvented
systems to drain the cylinder.
If you are absent during a relatively long period when there is a
risk of frost, make sure that you leave the central heating on and
that the temperature in the cylinder room and in all other rooms
are kept above freezing.
4.4 Cleaning the cylinder
• Clean the outside of the cylinder only with a damp cloth, using
soapy water if it is especially dirty.
Do not use abrasive cleaning agents or solvents (any type of
scouring agent, petroleum etc.) since they can damage the
cladding and the cylinder fixtures.
