Horizontal mounting on the ceiling
1. Mount pendulums or similar (not included
on delivery) on the ceiling with c-c distance
according to Fig. 6a and 6b.
2. Mount the brackets on the unit with an
hexagon key and the included M8 screws.
3. Put the unit in place and fix the brackets to
the pendulums.
Note! The unit needs to be secured if hung
from wires.
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 electrical connection may be done from
above or below when mounted vertically, and
from left or right when mounted horizontally,
according to ordering key. Control (230V~)
should be connected to a terminal block.
The control system is pre-installed in the
aircurtain with an integrated control card,
(see fig 8).
SIRe is supplied pre-programmed with
quick-release connections.
Modular cables are connected to the control
board Base, by opening the front plate, as
shown in Figure 4 and 5. See manual for SIRe.
Connection of water coil
The air curtain has a heating coil with copper
tubes 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.
The unit is connected from above or below
to Ø22 mm copperpipes, by compression
fitting or through welding the pipe work to the
unit.
The upper side of the heating coil is
equipped with ventilating valve in the unit.
The heating coil should be ventilated before
operation to prevent air locks.
When mounting the unit vertically, water
connection can be carried out from the top or
bottom. The connection from below can be
done the following way:

• Flexible hoses may be drawn through
drilled holes in the floor and connected to
the air curtain pipes. The flexible hoses are
connected to the system beneath the floor.
Note! At connection from below, avoid placing
hoses or pipes so that they obstruct the air
flow to the fans. If necessary, secure them to
avoid vibrations and prevent them from being
sucked into the fans.
When mounting the unit horizontally, water
connection can be carried out from the left
or right. The lid on the top side of the unit
is sliding to be adjustable to the water pipe
dimension. (see Fig 6a).
Adjustment of air flow
The direction and speed of the air flow
should be adjusted considering the load on
the opening. Compressive 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 bigger the angle needed.)
With an hexagon key, loosen the three
screws supporting the outlet grille. Angle the
grille outwards to obstruct the incoming cold
air.
Overheating
The over heat protection maintains the
exhaust temperature at +40 °C. If the
temperature should exceed anyway there is
an over heating alarm. For more information
see the manual for SIRe.
Maintenance
To ensure performance and reliability of the
air curtain inspection should be carried out
regularly, at least twice a year, but this can
vary depending on local conditions. This is to
secure the performance of the air curtain.
A clogged filter doesn't present a risk, but
will reduce the efficiency of the air curtain.
The inlet grille works as a filter and should
be vacuumed regularly. The water battery
should be cleaned when necessary in the
following way:
1. Disconnect the power supply.
