Step 2: Then the outlet pro
fi

dismantled from this panel.
Step 3: Place the interchangeable closing plate at the base of
the unit. For this, the screws used to fasten it to the lateral panel
must be reused.
7 - POSITIONING AND INSTALLATION
Return
The access panel to the return outlet features
dual locks which can serve as a hinge or can
be used to remove the panel.
Check that the locks are not blocked. Open the
locks with a 4 mm Allen key (in an anticlockwise
direction).
Note: the screws securing this structure are used to
fi
x the locking
part to the base of the unit. The screws required to secure the
pro
fi
le for the outlet are supplied in a bag.
Step 1: Remove the lateral panel completely. To do this it is
necessary to remove the screws that attach the panel to the pillars
(2 per side) as well as those which join the top panel. Also, it is
necessary to loosen other two screws on the top panel ( indicated
in the picture). All screws are M6 Allen type.

Step 4: Replace the lateral supply panel.
Step 5: Assemble the outlet pro

4 screws supplied in a bag (self-tapping screws M4.8).

The procedure is the same as that used for supply, except with
the B2 assembly and models 070 to 093 with R2 assembly (*),
in which it’s also required to change the position of the damper.
Step 1: Remove the screws (M6 Allen) connecting the rod of the
return damper to the drive. Then disassemble the return damper.

Step 2: Fit the damper on the panel, placing the panel on the side
of the unit, followed by the pro
fi
le for the outlet.
Step 3: Rotate the rod on the axis so that the drive crosses between
the return and fresh air dampers (see image below).
Step 4: The drive of the damper for the horizontal position is
composed of two parts (1 and 2). Disassembly the lower part
(2) secured with M6 Allen screws. The upper part (1) is the drive
necessary for the vertical position. Screw the part (1) to the
rotated rod.
(*) If the unit includes the optional “Freeze protection OAT + spring
shut-o
ff
dampers ”, it is not necessary to change the transmission,
since the return damper incorporates a servomotor.
