The heater is designed for permanent connection to a wall jack
or socket.
The device is connected to the AC mains system by putting the
power cord into a connection socket.
NOTE
The connecting cable can be extended using a cable of the
H05VV-F3G1,50 type. A direct connection to a permanently laid
cable may only be implemented up to a diameter of 1.5 mm²
(e.g. NYM-J3G1,5 mm²). 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, via timer or controller directly
on the device or via a radio receiver in connection with a radio-con-
trolled room thermostat. These items can be ordered as acces-
sories (see p. 15). 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 has a very large radiation component
®
and a very small convective component of the heating power.
For reasons of safety, the surface temperature is max. approx.
95 °C, therefore the total power of the devices is limited. This
is the reason why these devices can only be applied as an ex-
clusive heating in houses with a very good heat insulation.
The LAVA
infrared heating by ETHERMA mainly heats solid
®
objects and, only to a lesser extent, directly heats the room air.
Therefore, these devices are ideal for additional temperature
control. 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.
Only if the room is actually used, the LAVA
additionally switched on and the radiation takes over the task
of heating the persons. Depending on the size of the device, the
LAVA
infrared heating requires a certain time until the oper-
®
ating temperature is reached. Only then the radiation can take
its full effect.

Dimensional drawing: Connection circuit diagram
The glass panel produced for the product consists of 6 mm
single-pane safety glass (ESG) or 6 mm ceramic plate. This is
much more resistant in contrast to conventional glasses and
is designed for significantly higher impact forces. Neverthe-
less, you should avoid excessive stress. In case of damage, ESG
shatters into many small parts with blunt edges, so that the
risk of injury is minimized. When choosing the place of instal-
lation, please note that a negligible amount of tempered glass
still causes a so-called "spontaneous breakage", which means
that the glass shatters even without external influence. There-
fore, choose the installation location of the device in such a way
that even in these cases no danger to persons or objects is to
be expected.
MAINTENANCE AND CARE
The LAVA
heat via the surface in the form of radiation. The device does
not contain any parts requiring special maintenance. In order
to service your infrared heater, we recommend using a damp
infrared heating is
cloth. Please do not use any scouring agents, since they may
®
leave scratch marks on the surface.
ATTENTION:
If the main cable to the device is dam-
aged, it must be replaced immediately by a spe-
cialist.
infrared heating is designed so that it gives off its
®
ATTENTION:
When you want to clean the LAVA
infrared heating, the heating device must be cold!
