Equipment Details
Note: If just the cold water system is being
used, without water heater, the heater tank is
also filled up with water. In order to avoid
damage through frost, the water contents
must be drained by actuating the safety/drain
valve, also when the heater has not been
used. As an alternative, two shut-off valves,
resistant to hot water, can be fitted in front of
the cold and hot water connection.
Draining the water heater
1. Disconnect power for water pump (main
switch or pump switch).
2. Open hot water taps in bathroom and
kitchen.
3. Open safety/drain valve: Lever in vertical
position, position (f).
4. The water heater is now drained directly to
the outside via the safety/drain valve.
Check that the water contents have been
completely drained (10 litres).

warning plate).
