4. Appliance description

The appliance is an electric direct heater only for installation on
a wall.

The appliance is suitable as a full heating system in bathrooms,
for example, or for use between seasons and as a booster heater
in smaller rooms, such as hobby and guest rooms.

The air in the appliance is heated by a heating element and
expelled via natural convection through the air outlet grille at the
top. Cool room air fl ows in through the apertures at the bottom
of the appliance.

After mounting the appliance on the wall and making the
electrical connection to the main breaker, the appliance is ready
for operation.

5. CNS E Operation

26_07_31_0037

As soon as the selected room temperature is reached, it is
constantly maintained at this selected temperature through
periodic heating (the output of the appliance must correspond at
least to the required heat demand of the room).

If several appliances are installed in a single room, the setting
at the temperature selector on each appliance can be different.

To avoid excessive power consumption when windows are open,
you should stop the appliance while venting.

5.2 Frost protection

To disable normal heating but maintain protection against
freezing, turn the temperature selector as far to the right as
possible. In this position, the temperature controller switches
on the heating element automatically if the room temperature
drops below the frost protection temperature (45 °F / 7 °C).

5.3 Limiting the temperature controller

Using the two pins fi tted to the back of the control casing, you
can fi x the temperature controller at a certain setting or limit the
temperature setting range.

» Break out the pins.
» To prevent adjustment of the selected temperature, push a pin

into the hole opposite (see diagram).

6. Cleaning, care and maintenance

WARNING:

Before cleaning, make sure the power has been

!

turned off at the circuit breaker panel and that the
heating element of the heater is cool. Failure to do
so could result in serious burns, electrocution,
serious bodily injury, or death.

If a pale brownish discolouration appears on the appliance casing,
wipe this off as soon as possible with a damp cloth. Clean the
appliance when cold with ordinary cleaning products. Avoid
abrasive or corrosive cleaning products.

8. Safety

Only qualified contractors should carry out installation,
commissioning, maintenance and repair of the appliance.

8.1 General safety instructions

We guarantee trouble-free function and operational reliability
only if the original accessories and spare parts intended for the
appliance are used.

26_07_31_0171

DANGER: Electrocution
If you mount the appliance on the wall, do so in such
a way that control equipment cannot be touched by
a person in the bath or shower.

CAUTION:

-Only fi t the wall mounted appliance to a vertical

!

wall that is temperature-resistant to at least 185 °F
/ 85 °C.

-Observe the minimum clearances to adjacent object
surfaces (for minimum clearances see specifi cation
chapter).

-Never install the appliance directly below a wall
socket.

-Ensure that the power cable is not in contact with
any appliance components.

8.2 Instructions, standards and regulations

ENGLISH

CAUTION: Fire
Never spray cleaning spray into the air slot. Ensure
that no moisture can enter the appliance.

As part of regular maintenance, we recommend also having the
control components checked. The safety and control components
should be checked by a contractor no more than ten years after
commissioning.

7. What to do if ...

... the appliance does not heat up:
Check the temperature set at the appliance and the circuit breaker

box.
The appliance has a safety temperature controller that shuts

the appliance down if it overheats. After the cause has been
removed (for example air outlet or inlet apertures covered) and
the appliance has cooled down for a few minutes, operation starts
again.

If you cannot remedy the fault, contact your contractor. To facilitate
and speed up your enquiry, please provide the number on the type
plate (000000-0000-000000).

Observe all applicable national and regional
regulations and instructions.

Observe the Building and Garage Regulations [or
local regulations].
