9. System shutdown.
9.1 Central heating circuit.
 Leave the appliance connected to the main
electrical supply.
 Turn the room thermostat to its minimum
setting. The domestic water heater will remain
at its set temperature setting.
Note! On shutting down the central heating system,
it is recommended not to set the room thermostat
lower than 10ºC during the winter months. To
prevent the installation from freezing, it is
recommended that all radiator valves be left fully or
partially open.
9.2 Domestic hot water.
 Leave the appliance connected to the main
electrical supply.
 Switch off the domestic hot water by pressing
the 'Hot water' button. The ‘On’ indication
light will go out. (The stored water is protected
against freezing in winter months by an
automatic frost protection that activates on a
water temperature of 15ºC).
Note! The heating and domestic hot water
installation must be independently protected from
frost. The boiler's built-in frost protection facility
will only safeguard the appliance itself.

9.4 Disposal of the appliance
The Atmos Multi is made of a number of primary
materials, especially copper, aluminium and steel.
These materials can easily be separated and
recycled at the end of the life span of the appliance.
Therefore do not throw away the appliance, but
make enquiries at your local council or a scrap
dealer about disposal.
10. Routine Inspection and Servicing.
To ensure continued efficient operation of the
Atmos Multi, it must be checked and serviced as
necessary at regular intervals. The frequency of
servicing depends upon the individual installation
conditions and usage, but must be a minimum of
once per year.
The extent of the servicing required is determined
by the operating condition of the appliance when
tested by a fully qualified engineer.
10.1 Boiler pre-service inspection.
Warning!
Turn off the boiler electrical supply before
removing the appliance casing. The fan, gas
valve, three-way valve and central heating
pump are mains fed with 230 volts AC.
