General Instructions
Read these instructions carefully before
installation and use. Keep this manual
for future reference.
The guarantee is only valid if the units
are used in the manner intended by
the manufacturer and in accordance
with the Frico mounting and operating
instructions.
Application area
AR200 is especially suited for
environments with high demands in
respect of design. It is recessed in
ceilings above entry doors and other
small doors where the height is no
greater than 2,5 metres. A low height
makes it possible to install AR200 where
ceiling space is limited. The recessed
installation and low sound level makes
AR200 very discreet.
Protection class: IP20

Operation

Air is drawn in from underneath and
blown out downwards towards the
entrance so that it shields the door
opening and minimises heat loss. To
get the best curtain effect, the unit
must extend the full width of the door
opening.
The grille for directing exhaust air
is adjustable and is normally angled
outwards to achieve the best protection
against incoming cold air. The air speed
is adjusted to the desired airflow.
The efficiency of the air curtain
depends on the air temperature,
pressure differences across the doorway
and any wind pressure.
NOTE! Negative pressure in the
building considerably reduces the
efficiency of the air curtain. The
ventilation should therefore be
balanced!

Assembly and operating instructions

Installation

AR200 unit is installed horizontally with
the supply air grille facing downwards as
close to the door as possible, concealed
in the false ceiling. The only visible part
of the unit is the underside that is level
with the ceiling.
For the protection of wider doorways,
several units can be mounted next to
each other.
Ensure that the base plate is
accessible and can be fully opened.
The minimum distance from the
outflow to the floor is 1800 mm (see
diagram 4).

the 2 metre units) are fixed to the unit
during transport. Loosen these, turn
them around and screw into place on
the unit according to figure 1 on p.3.
2. Hang up on threaded bars (M8)
according to figure 2 on p.3 (not
included).
3. Adjust the height using the upper
nut so that the frame is level with the
ceiling. Lock using the lower nut.
Electrical installation
The installation, which should be
preceded by an omnipolar switch with
a contact separation of at least 3 mm,
should only be wired by a competent
electrician and in accordance with the
latest edition of IEE wiring regulations.
1. The base plate/service hatch is
opened by loosening the snap fixings
located on the down side (turn 90°)
and then loosening the base plate
from the rim. See fig. 3 and 4.
