General recommendations
Read these instructions carefully before using
the appliance for the first time. Keep these in-
structions in a safe place for future reference.
The warranty is only valid if the units
are used in accordance with the Frico
installation and operating instructions
Area of use
The radiant heaters are primarily used to
create comfortable heating on terraces,
balconies, openair restaurants etc. They can
also be used for selective heating in storage
rooms and workshops.
The Comfortinfra is also approved for
installation in bathrooms and shower rooms.
Protection class: IP24.
Positioning
The heaters must be placed so that they
enclose the area to be heated, see fig. 1 and 2.
The normal assembly height is 2–2,5 metres
above the ground/floor.
A rule of thumb for infrared heaters
equipped with metal tubular elements is that
750–1000 W/m² increases the experienced
temperature by about 10 °C. The output
demand can be reduced if the area to be
heated is protected. If the area only has a
roof, at least 1000 W/m² should be installed.
750 W/m² is sufficient if the area has three
walls. For enclosed areas, the output demand
must be calculated. A green house for
example requires 250-300 W/m². Optimum
comfort is achieved if the heat is distributed
from at least two directions.
Mounting
Mounting is very easy using the two brackets
(supplied as standard), which can be
mounted on the ceiling or wall in different
angles. When angle mounting CIR on the
ceiling, standard brackets can not be used
(the distance to the ceiling will be smaller
than the minimum distance 150 mm). The
distance between the brackets is adjustable
and can be chosen according to the most
appropriate place for installation. CIR can

Mounting and assembly instruction
CIR
also be suspended from wires. For minimum
mounting distance, see Fig. 3.
• CIR may only be mounted horizontally!
• The mounting brackets enable mounting
in three different angles for ceiling or wall
mounting. Parallel to the wall/ceiling, 18° or
36° angle.
• Choose the desired angle and fasten the
bracket onto wall or ceiling. The holes are
Ø5 mm, c-c distance is 25 mm.
• Fasten the heaters, snap into the brackets
and secure it by tightening the securing
screws (104 mm long) and the domed nuts
(spanner width 7 mm).
Electrical installation
The electrical installation should be
permanent and carried out by a qualified
electrician in conformity with prevailing
regulations. The CIR must be preceded by
an all-pole switch. CIR must not be placed
directly under a wall-outlet! A terminal block,
which enables connection to other heaters is
situated on the same end of the heater as the
name plate.
Please note that the inlet must be tight. A
cable of EKK or EKLK type or similar must be
used.
Minimum cross section area:
230V
protected by 10A (up to 2 kW) - min. 1,5mm²
protected by 16A (2—3,5 kW) - min. 2,5 mm²
400V
protected by 10A (up to 4kW) - min. 1,5 mm²
protected by 1 6A (4—6 kW) - min. 2,5 mm²
Maintenance
The heater is on the whole made of rustproof
material and usually does not require any
maintenance. Pollution can in the long run
dull the reflectors somewhat. This however
has very little affect on its function. If the
heater is very dirty it can be cleaned with
compressed air. If the reflector remains
dirty it must be replaced by an authorized
repairman. The reflector must not be polished
as this may damage the protective surface.
