10.1 filling the cylinder
Use the draw-off points to bleed the cylinder and water
pipes. Do not use the combined temperature/pressure
relief valve of the cylinder or the pressure relief valve
of the cold water safety assembly for bleeding, since
foreign bodies can contaminate or damage the valves.
• Make sure that the drain valve is closed.
• Open all of the draw-off points in the cold and hot water pipes.
• Open the water supply inlet to the cylinder and allow the water
to run until bubble-free water runs from all of the draw-off
points and the air is removed from the system.
• Close all of the draw-off points.
• Check the system for leaks. In particular, check the installed
electric immersion heater for leaks.
• Open two hot water draw-off points, one at the lowest point
and one at the highest point of the pipe system, and allow
water to run for at least 5 minutes.
• Close both of the hot water draw-off points.

• Dismantle the electric immersion heater cover.
You can set the hot water temperature by turning the knob with
the arrow pointing at the numbers 1 to 5. The following table
gives in indication of approximate hot water temperature for each
setting:
Setting hot water temperature
- 1 20 °C
- 2 35 °C
- 3 45 °C
- 4 60 °C
- 5 68 °C
• Place the cylinder thermostat (1) and the electric immersion
heater thermostat (2) for start-up into the central position
(around 45°C) to achieve maximum energy efficiency.
We recommend the cylinder is set to 60 °C
periodically, to provide protection against the
proliferation of harmful bacteria.
• Place the gas-fired boiler into operation until the cylinder
reaches the operating temperature and all radiators in the
system are hot.
• Then drain the entire central heating system again to remove
any residue from the pipes.
• Fill and bleed the central heating system again as described in
the installation manual of the gas-fired boiler.
