NSTALLATION
The FWD air conditioning and hot-air heating units may be
installed either in horizontal or vertical position. Check that
the desired installation complies with one of the pictures
shown in figure 3 in which both possible configurations (AA
or AB) are suitable to work for heating and cooling.
Horizontal or vertical installation
(See figure 3)
AA Inlet and outlet of air are in a straight line
AB Inlet of air is not in a straight line with the outlet of air
Configuration of the unit
The units are always supplied in AA configuration, but the air inlet
position may be changed during the installation.

2 Lower closing panel
3 Pre-sheared element for external air inlet
4 Centrifugal fans
5 Standard heat exchanger
6 Additional heat exchanger (DF)
7 Condensate tank for wall mounting (tube Ø3/8")
8 Condensate tank for ceiling mounting (tube Ø3/8")
9 Heat exchanger hydraulic attachments
10 Condensate discharge attachments
11 Terminal strip
12 Load-bearing structure
It is advisable to install any accessories on the standard equipment
before positioning it, referring to the technical sheets.
The sections of the inlet and delivery pipes are rectangular and drilled
with holes for fixing the available accessories. A round pre-sheared
element (Ø100 mm) is present on both side panels of the unit for the
direct inlet of fresh air.
If the installation differs from the supply terms, the layout must be
changed by dismantling the unit as shown in figure 6.
It is possible to orient the exchanger's attachments on the opposite
side as follows:
1 remove the upper and lower closing panels (1+2),
2 remove the condensate tank for the horizontal installation (8),

3 loosen the 4 fixing screws of the motor support, without
unscrewing them all the way (7),
4 remove the heat exchanger (5) by unscrewing the 4 fastening
screws, pull it out and turn it; eliminate the pre-sheared elements
on the opposite side panel, re-insert the heat exchanger and
tighten the screws,
5 reassemble the previously listed components,
6 stop the outlet holes of the previously used manifolds with
anticondensing insulating material.

Installing the unit

Fix the standard unit to the ceiling or wall using at least 4 of the 6
slots;
■
For horizontal installation (ceiling mounting) it is advisable to
use M8 threaded bars, screw anchors suitable for the unit's
weight and to arrange for the positioning of the unit using 2 M8
bolts and a washer the diameter of which is suitable for inserting
the slot and for then fixing the unit.
Before tightening the check nut, adjust the closing of the main
nut so that the unit will slant correctly, i.e. for facilitating the
discharging of the condensate (see figure 4).
The correct slant is achieved by tilting the inlet downwards as
compared to the outlet until a difference in level of about 10 mm
is obtained from one end to the other. Make the hydraulic
connections with the heat exchanger and, for cooling operations,
with the condensate discharge. Use one of the 2 drains of the
auxiliary tank, visible on the outside of the unit's side panels
(see figure 5): horizontal (tank) and vertical condensate
discharge.
■
For vertical installations (wall mounting), fix the unit so that
water flow out toward the condensate discharge used. A slant
equivalent to a difference in level between the two side panels of
about 5 mm is enough.
The two condensate discharge tubes of the main tank are
located inside the side panels and may be accessed through a
membrane type passage that should be perforated for passing
the discharge tube through it.
It is advisable not to remove the aforesaid membrane type
passage because it prevents the sharp edge of the hole on the
side panel from damaging the condensate discharge tube over
time.
■
To connect the unit to the condensate discharge line, use a
flexible rubber tube and fix it to the chosen discharge tube (Ø3/8")
by means of a metal clamp (use the discharge that is located on the
hydraulic attachments side).
To assist the draining of the condensate, slant the discharge
tube downwards by at least 30 mm/m making sure that its entire
route is clear and free from bends or blockages.
■
Installation of air filter. For inlet, the filter module may be
installed either in the same line as the outlet (configuration AA)
or at 90° as compared to the unit (configuration AB). In the latter
case the front lower closing panel must be moved by adjusting
the 6 screws that fix it to the unit. The panel will then be installed
at the bottom of the unit.
Both ends of the filtering module are drilled to match the holes
on the intake inlet of the unit.
As such, it will be possible to couple the module to the unit and
achieve, at the other end, a positioning of the holes that is
identical to that of the intake inlet of the air handling unit.
The drilled holes at one end of the module are Ø5 mm; this is
the part that is to be coupled directly to the unit.
At the other end the diameter of the holes is 3.5 mm to ensure
that the screws, which will be used for fixing other parts (field
supply) will be tight.
The overall dimensions are shown in figure 2.
