Safety/drain valve with antifreeze
The safety/drain valve is mounted on the floor
in front of the boiler.
When the button is out the valve is closed. To
drain the boiler, press the button in.
Note
The valve only works when the power supply
is guaranteed. If the body battery is
disconnected or discharged, the valve will
open and the boiler will drain.
At temperatures below 3°C the antifreeze
safeguard will drain the boiler automatically
at the drain valve to prevent any frost
damage to the unit.
If the temperature drops below the response
value during operation, turn the knob C to on
the control element to winter mode (down)
and close the valve by pulling the button out.
The valve will only close from an ambient
temperature of 8°C.
Filling the boiler
1. Pull the button on the safety valve out. At
temperatures below 8°C, switch on the
heating first so that the valve will not open.
2. Switch on water pump at control panel
(p. 6-1).
3. Set single-lever mixer tap in the bathroom
or kitchen to "Hot" and leave open until the
water flows in a powerful stream.
Note
When filling the boiler, take care to ensure
that the drain valve for fresh water pipes is
closed (p. 7-2).
