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 Comfortline AZR 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.
AZR is recessed in false ceilings above
entrances.
Protection class above roof: IP23,
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
AZR 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.
Ensure that the service hatch is accessible
and can be fully opened.
