Use of electrical equipment in principle re­
quires care to exclude any potential risks from
fire, electrical shock or injury. Therefore the
unit should only be used as described in these
instructions, where any use outside the manu­
facturer's recommendations can lead to dam­
age or injury.
The correct match between the heat require­
ment of the room and the heating power of
the unit must be observed.
Before use of the unit, read the entire instruc­
tions and follow the information given on
proper handling of the unit.
These instructions should be kept
carefully and handed to any subse-
quent user of the unit. Please show them to
the engineer performing any repair work.

1.1 Description

The CNS is an electric direct heater exclusive­
ly for wall installation. It is suitable e.g. for heat­
ing a bathroom or as transitional or additional
heating for small rooms such as hobby rooms
or guest rooms.
Series CNS-S
After wall mounting and electrical connection
via a plug and socket, the unit is ready for use.
Series CNS-U
After wall mounting and electrical connection
via a fixed connection through a junction box
(note national regulations), the unit is ready
for use.
Function
The air in the convector is heated by heating
element and emerges by natural convection
at the top through the air outlet grille (4). The
openings in the underside of the unit provide
cooling room air
Safety device
The convector has a protective thermostat
(STR) which switches the appliance off on
overheating. After eliminating the cause (e.g.
covered air outlet or inlet opening), after a
cooling down period of a few minutes the unit
resumes operation.

1.2 Operation
The convector is switched on and off via the
switch (1) on the right­hand side. The desired
room temperature is set via the temperature
1
selector (2) anywhere between around +6°C
and +30 °C. As soon as the set room tem­
perature has been reached, it is maintained
constantly by intermittent heating (the heating
power of the unit must correspond at least to
the heat requirements of the room).
If several heaters are fitted in a room, the
temperature setting on each unit may vary.
To avoid excessive energy consumption
with the windows open, the unit should be
switched off during ventilation at the switch (1).
Frost protection
If the unit is used as a frost guard, set the tem­
perature selector (2) to the far right stop (*).
In this position the thermostat switches the
heating on automatically if the room tempera­
ture falls to around +6°C.
Limiting the thermostat
Using the two pins on the back of the switch
housing (3), the thermostat can be fixed in a
particular setting.
b
To fix a desired temperature, push pin
the hole opposite.
To limit the temperature adjustment range,
set the minimum and maximum values on the
selector knob and mark these by inserting pin
b into the opposite, slightly offset hole each
time.
1.2.1 External room thermostat
If necessary the unit can be operated with a
commercial external room thermostat. The
temperature selector (2) must be turned to
the right stop (MAX). The room thermostat
should be located as far as possible from the
unit and at least 1.5 m high.
1.2.2 Shutting Down
To shut down the unit, move the switch to the
OFF position and remove the mains plug from
the wall socket (do not pull out the plug using
the lead).

– in rooms at risk of explosion or fire from
chemicals, dust, gas or vapour,
– in the immediate vicinity of pipes or con-
tainers which transport or contain flam-
mable or explosive substances,
– if the minimum distances from adjacent
object surfaces are not observed.
• Installation (electrical installation), first op­
eration and maintenance of this unit may
only be performed by an accredited expert
according to these instructions.
• The unit must not be operated if in the
same room work is performed such as floor

must not be covered.
• A For objects of all types e.g. furniture,
curtains, hangings or textiles or other flam­
mable or non­flammable materials, the fol­
lowing minimum distances from the unit
must be observed:
To the air outlet grille ⇒
