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. See manual for SIRe.
Unit with water heating
Connected via the built-in control board SIRe
with 1,5 m cord and plug.
Unit with electrical heating
The electrical installation is made on the
top of the unit, fig.2. Control supply (230V~)
and power supply for heating (400V3~) are
connected to terminal block in the internal
connection boxes. 2-metre units require dual
power supplies.
The largest cable diameter for the terminal
block is 16 mm². The cable glands used must
meet the protection class requirements. In
the distribution board it is to be indicated that
"the air curtains can be supplied from more
than one connection".
See wiring diagrams.
Start-up (E)
Note! When using for the first time or when
starting up after a long period of disuse, a
small amount of smoke and a slight odour
may occur temporarily, which is completely
normal.

Connecting the water coil (W)
The installation must be carried out by an
authorised installer.
The water coil has copper tubes with
aluminium louvres 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 with ø15 mm smooth copper
pipe with a suitable coupling or soldering.
The connections to the heating coil must be
equipped with shut off valves (not included)
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.
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.
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.
Basic setting fan speed
The fan speed when the door is open is set
using the control. Note that the air flow
direction and fan speed may need fine
adjustment depending on the loading of the
door.
Filter (W)
The water coil is protected against dirt and
blockage by an internal air filter which covers
the coil face.
