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
The Thermozone AR300 air curtain unit is
supplied with electrical heating or hot water
coil and is intended for installation above
entrances and smaller doors up to 3.5 metres
in height.
AR300 is recessed in false ceilings above
entrances.
Protection class above false ceiling: IP44,
below false ceiling: 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(s) 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!
Installation
AR300 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,

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 service hatch is opened by loosening
the snap fixings located on the down side
(turn 90°). See fig. 3.
2. AR300W: The unit is fitted with cable and
plug.
AR300E: The unit is supplied through cable
glands on the side of the unit using a five-
core cable with an earth wire. The largest
cable diameter for the terminal block is
16 mm². To use accessories DSAR300 and

be made in the casing. The cable glands
used must meet the protection class
requirements.
