Frico AGS5500 Original Instructions Manual page 17

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
The AGS5500/AGR5500 air curtain unit is
supplied without heating or hot water heating.
AGS5500/AGR5500 is intended for entrances
and doors, with installation height up to
5,5 metres. AGS5500 is surface mounted and
AGR5500 is intended for recessed mounting.
Protection class: IP24.
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 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 is installed horizontally with
the supply air grille facing downwards as close
to the door as possible. 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 M10 fixed nuts on the upper
side (6 on 2 and 2,5 meter models, 8 on 3
meter model) for ceiling installation using
threaded bars, or for installation using wall
brackets (accessories). See fig. 5.

Assembly and operating instructions
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.
The control system is pre-installed in the
air curtain with an integrated control card.
SIRe is supplied pre-programmed with quick-
fit connections. Modular cables are connected
to the control board. AGS5525/5530 and
AGR5525/5530 have two SIRe-cards, one of
them being slave connected. See manual for
SIRe.
Operation (230V~) is connected to
terminal block in the junction box on top of
the unit. 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 on the upper side
of the unit via connections, see table fig. 1A-
B.
The connections to the heating coil must be
equipped with shut off valves to allow problem
free removal. Water coil is equipped with a
drain valve. A vent valve should be connected
at a high point in the pipe system.
Air valves are not included.
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. Generally
speaking, the higher the load, the greater the
angle that is needed.
