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
SIHF-J3G1.5 mm² type. A direct connection to the device cannot
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-con-
trolled room thermostat (ET-14A). These items can be ordered
as accessories. Please observe the operating instructions
of the respective 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 surface temperature is max.
approx. 120 °C, therefore the total power of the devices is lim-
ited.
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 tem-
perature control. But they can also be used as stand-alone sys-
tem. 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 performance and thermal insulation standard. De-
pending on the size of the device, the LAVA
device requires a certain time until the operating temperature
is reached. Only then the radiation can take its full effect.
ATTENTION: Depending on the output and size of
the device, these can deform slightly during heat-
ing operation.
MAINTENANCE AND CARE
The LAVA
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.

whether from persons or objects leaning against
it or from other forces, must be avoided!
