1. Operating instructions

The installation and use of electrical appliances
must be carried out with due caution in order
to avoid the risk of fire, electric shock or injury.
The equipment must only be used as described

Range of use
The CS 20 (L) is suitable for heating rooms
that are used infrequently, or to supplement
an existing heating system.
These units can be used as mobile free-stand-
ing units with the feet fitted, or alternatively as
wall hanging units.
The use of the heater in bathrooms or similar
damp environments is not permitted. The
heater should not be used outdoors.
The heat requirement of the room should
be matched to the heat output of the unit. In
very small rooms there is a risk of overheating,
damage and fire.
As a free standing appliance it can easily be
used wherever heat is required (when used as a
mobile free standing unit both feet must be fit-
ted before switching on). The connection cable
should not be covered with a carpet or mat,
and should lie outside any 'traffic area' where it
could be caught and the heater overturned.
The use of an extension lead should be avoid-
ed. If an extension lead is used it should be of
sufficient cable size for the full rating power of
the heater. It should have a moulded plug and
socket and sufficient preventative measures
should be taken when using it.
The equipment should always stand on a solid
floor, on soft ground the appliance can tilt or
the air grilles could be blocked.

When transporting the appliance it should
be held only by the recessed grips provided
for this purpose (6), under no circumstances
should it be carried by the mains electrical cable.
Function
To heat the air, ambient air entering the unit
through the openings in the base of the unit
is heated, this then flows out by means of
natural convection, via the air outlet grille (4)
at the top.
In the case of the CS 20 (L), this process can
be assisted by using the integral fan to push
heat out through the separate outlet grille (5).

1.2 Operation

The operating controls are located within the
left hand side section of the unit.
Using the thermostat knob (1), the desired
room temperature can be selected between
approximately 5 °C and 35 °C.
The thermostat within the unit then keeps the
ambient air constantly at this set value, by cy-
cling the heating on and off for short periods.
Using the switches (2), three different heat out-
put levels can be selected (750 / 1250 / 2000 W,
see table). This gives increased economy by
adapting to the prevailing heat requirement.
Frost protection
If the unit is used as a frost protection safe-
guard, the thermostat knob should be turned
anticlockwise to the end limit stop
of the two selector switches for heat output
