General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The guarantee is only valid if the
Thermozone units are used in the manner
intended by the manufacturer and in
accordance with the Frico installation and
maintenance instructions.
Application area
The AG4000 air curtain unit is intended for
installation above entrances and doors from 2
metres up to 4 metres in height.
AG4000 is installed above the entrance.
Protection class IP23.
Operation
Air is drawn in at the front side of the unit
and blown out downwards towards the
entrance so that it shields the door opening
and minimizes heat loss. To get the best
curtain effect the unit must extend the full
width of the door opening.
The grille for directing supply air is
adjustable and is normally angled outwards to
achieve the best protection against incoming
cold air.
The airflow can be adjusted by use of the fan
speed selector.
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
The unit is installed horizontally with the
supply air grille downwards as close to the
door as possible, preferably against the wall
and immediately above the doorway. For the
protection of wider doorways, several units
can be mounted next to each other. Ensure
that the service hatch is accessible and can be
fully opened.
The unit has 4 (6 on 2 metre models)

Assembly and operating instructions
M8 fixed nuts on the upper side for ceiling
installation using threaded bars, or for
installation using wall brackets (accessories).
See dimension diagrams pages 2-3.
Electrical installation
Electrical connection may only be carried
out by an authorized electrician, and in
accordance with these instructions and the
applicable regulations.
1. The service hatch is opened by slackening
off the screws on the underside of the unit
as illustrated on page 3.
2. The unit is connected via one of the cable
glands in the upper side of the unit.
Different combinations for controlling fan
speed and heat output are available. See
wiring diagrams (pages 5 - 9). Connections
are made using EKK, EKLK or corresponding
type cables. The cable glands used must meet
the protection class requirements. For units
with electrical heating, the power and control
voltage can be supplied separately. It must be
indicated in the distribution board that "The
air curtains are supplied from more than one
connection".

Adjustment of the air curtain and air flow
The direction and speed of the air flow
should be adjusted considering the load on
the opening. Pressure forces affect the air
stream and make it bend inwards into the
premises (when the premises are heated and
the outdoor air is cold). The air stream should
therefore be directed outwards to withstand
the load. Approximately 15° is a suitable
angle. Generally speaking, the higher the load,
the greater the angle that is needed.
