NSTALLATION
Remove the cabinet, where existing, by unscrewing the 4 fastening
screws reachable through the lifted side doors (see figure 2). In case
of FWL versions, also unscrew the 2 screws on the front panel.
Install the basic unit onto the wall/ceiling using the 4 mounting slots
and the supplied anchor screws, keeping the unit at least 100 mm
above the floor for a proper air suction and an easy pulling out of the
filter in case of FWV and FWM models. In case of ceiling models
FWM and FWL verify that the installation height corresponds to what
is specified in figure 3, in order to avoid excessive hot air stratification
in the upper part of the room; in case of greater installation heights
we suggest to proceed with the back suction from the lower part of
the room. The installation heights refer to the maximum running
speed.
Carry out the hydraulic connections to the heat exchanger and in
case of cooling operation, to the water drainage system.
In case of cooling applications, make sure to insulate all field installed
piping and fittings as to avoid condensate dripping on the floor. Non
insulated piping can cause water damage!
We suggest to provide for the water inlet from the bottom side of the
heat exchanger and the outlet on the upper side.
For a better water drainage lean the drain pipe downwards at least
3 cm/m avoiding loops or narrowing on its way.
