Do not turn the thermoCOMPACT boiler OFF if a

hot water.
Care and maintenance
Clean the outer casing of your boiler with a damp cloth
and a little soap. Do not use abrasive or solvent cleaning
agents that may damage the case or the plastic fittings.
The appliance should be serviced at least once per year.
To ensure regular servicing, it is strongly recommended
that arrangements are made with your service agent or
Vaillant Ltd. For further details please contact Vaillant
Service Solutions: 0870 6060777.
Frost protection
Your boiler is equipped with a frost protection function:
If the heating water temperature drops below 5 °C when
the main switch is ON, then the boiler goes into operati-
on and heats the boiler circuit to approx. 30 °C.
It cannot be guaranteed that water will circulate
throughout the entire heating system.
If the boiler is not operated for several hours during
very cold weather there is therefore the possibility of
the system freezing. Please ensure that if you are absent
during a period of frost the central heating remains in
operation and all rooms are kept above freezing point.
It must be remembered, however, that the boiler will be
automatically switched off by the built in monitoring
devices if certain faults occur, e.g. interruption in the gas
or electricity supply or faults in the flue gas system. To
overcome this possibility you can drain both the central
heating system and boiler.
Frost protection and monitoring devices can
only function when the main switch of the unit
is set to the „I“ position and the boiler is
connected to the electrical supply.
