Switching off the unit

CAUTION
Drain the unit and the installation, if the mains
electricity supply is interrupted and there is a risk of
freezing.
1. Remove the plug from the socket.
2. Drain the unit with the filling/draining tap.
3. Drain the installation at the lowest point.
4. Close the main tap of the hot and cold water supply to the unit.

6.3.1 Frost protection
In order to prevent the condense outlet from freezing, the unit must be installed in a
•
frost-free room.
The unit is fitted with frost protection in order to prevent it from freezing. If the
•
temperature of the heat exchanger drops too low, the boiler will switch on until the
heat exchanger has heated up. If there is the possibility that the installation (or a
part thereof) may freeze, an (external) frost thermostat must be fitted at the coldest
place, on the return pipe. This must be connected in accordance with the electrical
diagram (see par. 9.2).
Note
If an (external) frost thermostat has been fitted on the installation and has been
connected to the unit, it will not be active if the unit on the operating panel is switched
-
off ( on service display).
