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.
Electrical installation
The installation, which should be preceded
by an omnipolar switch with a contact
separation of at least 3 mm/0.12 in, 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, (see fig. 2).
SIRe is supplied pre-programmed with
quick-fit connections.
Modular cables are connected to the control
board. See manual for SIRe.
Unit without heating or with water heating
Connected via the built-in SIRe control board.
See wiring diagrams.
Vertical mounting PA4JK
Units from 1.5 metres/4.9 feet and longer may
be used vertically. For vertical mounting, all
units must be supplemented with a vertical
kit containing everything needed for a
practical installation of floor standing units.
The unit can be reversed and placed on
either side of the door. Connections and PC
Board SIRe are positioned near floor level
when the air curtain is placed to the left of
the door and at the top when it is placed to
the right (seen from the inside).
The accompanying floor edging is attached
to the floor with fasteners appropriate to the
surface.
Two units can be mounted directly on top of
each other, the floor edging is then used as a
joining bracket.
The air curtain must be secured to wall or
ceiling.
A design kit which gives a neater installtion
that conceals cables and pipes is available as
accessory, se accessories pages.
See fig. 11 and separate manual.
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. Steel
connection pipe. 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 top of the
unit (horizontal mounting) or on the reverse
(vertical mounting) via connections DN20
(3/4’’), external thread. Flexible hoses are
available as an accessory, see accessories
pages.
The connections to the heating coil must
be equipped with shut off valves (included
in Frico valve kits) to allow problem free
removal.
A vent valve should be connected at a high
point in the pipe system. Air valves are not
included.
For vertical installation and bottom water
connection it is not possible to bleed the coil
in the unit. Ensure that the water coil is filled
with water and that no air remains, prior to
commissioning. See fig. 4.
Our recommended solution is to use a
T-connection and shut off valves. Small air
bubbles may remain, but will disappear with
normal operation. NOTE: Care must be taken
when connecting the pipes. Use a wrench or
similar to hold the air curtain connections to
prevent straining of the pipes and subsequent
water leakage during connection to water
supply pipe-work.
