DUCT CONNECTION
All the units are provided with a centrifugal fan that can be ducted. If supply only should be ducted, a flanged connection with overall
dimensions larger than discharge hole located on the top of the unit should be used (please refer to unit dimensional drawing). In
case also the suction side should be ducted it is necessary to connect the return duct with a flange having the same dimensions of
the filter frame (See next picture).

WARNING: It is compulsory to install an air filter on the unit suction side; unit without filter can have un
proper operation or be damaged. The presence of the filter is to be considered mandatory; warranty will
no longer be valid if it is removed.
WARNING: When ductworks are connected it is IMPORTANT to check if the airspeed through the
evaporator is around 1,5÷ 2 m/s. This parameter allow the unit to operate with the maximum efficiency;
so an airspeed over than 2 m/s should never been exceeded.
HOW TO REMOVE FILTERS
SHH units are supplied standard with a removable G3 filter ; (see picture) the filters can be removed by sliding laterally the cells
after removal of the fixing knobs.
