DX 421, DX 422T
4 Electrical Connection
The voltage specified on the type plate must match the
local mains voltage.
The device plug must always be accessible.
5 Operation
The room temperature is regulated using the infinitely
adjustable thermostat (C). If the rotary knob is set to
the lowest setting i.e. to the extreme left (see figure),
the thermostat switches the heating device on at an
ambient temperature of approx. 5°C.
The heating device is switched on and off using the
power switch (D).
Two heating levels (I = 1000W or II = 2000W) can be
selected using the operating mode switch (E).
The red light illuminates when the device is in heating
operation.
ATTENTION!
Depending on the size of the room, heat requirement
and thermostat setting, rooms may overheat if the
heating is not controlled. This can be dangerous for
people who are not able to leave the room as it gets too
hot.
5.1 Fan operation (device type DX 422T only)
Switch F switches on a fan which causes faster heat
distribution through increased air recirculation.
The fan can also be used as cold air fan.
In cold air fan operation, turn the thermostat rotary
knob to the maximum (clockwise).

6 Protection Against Overheating
If the permissible temperature is exceeded, the heating
device switches off automatically. If this occurs, pull the
mains plug out and leave the device unplugged for a
few minutes, so that the temperature limiter can switch
back again.
Then remove the cause e.g. when the air grid is
blocked or covered. When the device has cooled suffi-
ciently, it can be started up again.
7 Faults
If the heating device does not give off heat, check the
following points:

Is the power switch (B) in the ON position?
 Has the thermostat been set to the desired temper-
ature?

Has the overheat protection been triggered? See
chapter 6!
 Is the fuse in the fuse box switched on?
If you cannot remedy the fault, please contact your
electrical retailer. To process your order, please state
the device type as well as its production number (E Nr.)
and manufacturing date (FD). This information is listed
on the type plate.
8 Cleaning
To clean the device, first disconnect it from the mains
and allow it to cool down. Clean the outside of the unit
using a soft, damp cloth. Do not use scouring powder
or furniture polish as this may damage the surface.
Dust which gathers inside the device can be removed
from the outside using a vacuum cleaner.
9 Warranty
Please contact your local dealer for information on the
warranty conditions. The warranty is not valid without a
sales receipt marked with the date of purchase.
10 Note on Disposal
Do not dispose of the unit with general house-
hold waste. The device must be taken to a local
waste disposal plant.
