• Check if the rotary switch for the drain
valve is set to “Operation” (parallel to the
water connection) and engaged.
• Close the drain valve by pushing the
button until it engages.
• When the temperature at Frost control
is below about 7°C, first switch on
the heater to warm the installation
compartment and Frost control. After
several minutes, when the temperature at
Frost control is above 7°C the drain valve
can be closed.
• Switch on power for water pump (main or
pump switch).
• Open hot water taps in kitchen and
bathroom (set preselecting mixing taps or
single-lever fittings to “hot”).
• Leave the fittings open for as long as it
takes for the boiler to displace the air
and fill up and the water to flow without
interruption.
If just the cold water system is being operated
without using the water heater, the heater tank
also fills up with water. To avoid frost damage
the boiler must be drained through the drain
valve even if it was not operated.
When connecting to a central water supply
(rural or city mains) a pressure reduction valve
must always be installed to prevent above 2.8
bar from developing in the water heater.
