Installation and operating instructions
General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The product may only be used as set out in
the assembly and operating instructions. The
guarantee is only valid if the product is used
in the manner intended and in accordance
with the instructions.
Application area
AGI is a robust air curtain intended for
vertical or horizontal installation in large
doorways such as logistic centres, loading
bays and warehouses. Recommended
installation height AGI4500: 4,5 m and
AGI6000: 6 m. The air curtain is available
without heat and with water heating.
Protection class: IP54.
Operation
Air is drawn in at the top/rear of the unit and
blown out downwards/outwards so that it
shields the door opening and minimizes heat
loss. To achieve the optimum air curtain effect
the unit must extend the full height/width of
the door opening.
The grille nearest the door is adjustable and
is normally angled outwards to achieve the
best protection against incoming cold air.
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.
Mounting
The air curtain range includes variants for
horizontal and vertical installation. See
dimension drawings.
Horizontal mounting
The air curtain is installed horizontally with
the supply air grille facing downwards as close
to the door as possible. The unit is suspended
from the ceiling by threaded rods. For the
protection of wider doorways, several units
can be mounted next to each other.
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.
Control (400V3~) is connected to the
terminal block in the junction box. The cable
glands used must meet the protection class
requirements. See wiring diagrams.
Connecting the water coil (W)
The installation must be carried out by an
authorised installer.
The water coil has copper tubes with
aluminium fins and is suitable for connection
to a closed water heating system. The heating
coil must not be connected to a mains
pressure water system or an open water
system.
Note that the unit shall be preceded by a
regulating valve, see Frico valve kit.
The water coil is connected via connections
with dimensions as given in the table
(see diagram) on the side of the unit. The
connections to the heating coil must be
equipped with shut off valves to allow problem
free removal.
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
Vertical mounting
The air curtain is mounted vertically as close
as possible to the door. For the best effect air
curtains should be placed on both sides of the
opening.
The unit can be turned and positioned on
either side of the door. The air curtain is
mounted on a floor frame which is included.
The edging is attached horizontal to the floor
using fasteners appropriate for the surface.
See Fig.2.
Two units can be mounted directly on top
of each other, they are fastened together with
supplied fastening plates. The air curtain
must be secured to wall or ceiling.
