board Base, by opening the service hatch, as
shown in fig. 3 and 5. See manual for SIRe.
1. The service hatch is opened by loosening
the snap fixings located on the down side
(turn 90°). See fig. 3.
2. AR3500A: The unit is fitted with cable and
plug.
AR3500W: The unit is fitted with cable and
plug.
AR3500E: The unit is supplied through
cable glands on the side of the unit. For
units with electrical heating, power and
control should be supplied separately.
Control (230V~) and power supply for heat
(400V3~) should be connected to a terminal
block in the terminal box. 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".
3. Close the service hatch and make sure that
the snap fixings lock properly.
See wiring diagrams.

Start-up (E)
When the unit is used for the first time or
after a long period of disuse, smoke or odour
may result from dust or dirt that has collected
on the element. This is completely normal
and disappears after a short time.
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.
To access the connections (DN20, 3/4",
inside thread) the service hatch and intake
grille must be opened. The water coil is
connected inside the unit through holes
which are made (during installation) on the
upper side or through the side of the unit,
possible places are marked with punch marks.
The connections to the heating coil must be
equipped with shut off valves to allow problem
free removal.
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.
See fig. 4.
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 speed control. Note that the air flow
direction and speed may need fine adjustment
depending on the loading of the door.
Filter (W)
The heat coil fin distance, in combination
with the hole diameter of the intake grille,
protects against dirt and blockage and makes
a separate filter unnecessary.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. The service hatch is opened by loosening
the snap fixings located on the down side
(turn 90°). See fig. 3.
