The heater is intended for the fixed connection to a ceiling or
wall socket.
The device is connected to the AC mains system with a pow-
er cord connected and a connection socket on the installation
side.
NOTE
The connecting cable can be extended using a cable of the
H05SS-F3G1.5 mm² type. A direct connection to the device can-
not be implemented. The length of the connecting cable must
be between 1.0 and 1.9 m.
An all-pole disconnecting device with a minimum contact open-
ing width of 3 mm has to be mounted into the fixed electrical
installation in compliance with the installation regulations.
HEATING MODE
The heater is operated by means of direct connection via
switch, via an external room thermostat (eTOUCH eco), or via a
radio receiver (ET-111A) in connection with a radio-controlled
room thermostat (ET-14A). These items can be ordered as ac-
cessories. Please observe the operating instructions of the re-
spective product.

HEATING MODE
Depending on the thermal insulation standard, you require
a heating power between 30 and 200 W/m² living space. The
LAVA ® infrared heating device has a very large radiation com-
ponent and a very small convective component of the heating
power. For reasons of safety, the maximum surface tempera-
ture is approx. 120 °C, therefore the total power of the devices
is limited.
The LAVA ® infrared heating device by ETHERMA mainly heats
solid objects and, only to a lesser extent, directly heats the
room air. Therefore, these devices are ideal for additional heat-
ing. But they can also be used as stand-alone system. In order
to achieve the same feeling of comfort as with a convection
heating, the room air temperature can be reduced by approx.
2–3 °K. Each degree that the heating is reduced can save up to
approx. 6% of the heating costs, depending on the heating per-
formance and thermal insulation standard. Depending on the
size of the device, the LAVA

ATTENTION: Depending on the output and size of
the device, it can deform slightly during heating
operation.

then the radiation can take its full effect.
MAINTENANCE AND CARE
The LAVA ® infrared heating device is designed so that it gives
off its heat via the surface in the form of radiation. The device
does not contain any parts requiring special maintenance. We
recommend commercially available glass cleaners for the care
of your infrared heating. Please do not use scouring agents, as
these can cause scratches both on the glass and on the painted
surfaces.
ATTENTION: The LAVA
must be cold before cleaning!
ATTENTION: Strain of any kind on the surface,
whether from persons or objects leaning against
it or from other forces, must be avoided!
