 A minimum clearance of 76 mm plus the duct diameter size (fig. 6 3,
page 6) is required behind the supply-air grille for attaching the duct-
ing (fig. 2 11, page 3).
➤ Create the cut outs for the round supply-air grille according to the
following table:

4.4" x 4.4"
112 x 112 mm
➤ Mount the supply-air grille.
8.6 Return-air Grille
The following guidelines should be followed during the installation of the
return-air grille to ensure direct uninterrupted airflow to the evaporator:
 Install the return-air grille as low and as close to the unit as possible.
 Install the return-air grille away from exhaust and bilge vapors.
 The return-air grille should have a minimum of 107 mm of clearance
in front of it in the cabin area.
➤ Create the cut out for the return-air grilles according to the following
table:
MCS6
9.6" x 7.6"
244 x 194 mm
➤ If your kit is supplied with a filtered return-air grille: Remove the filter
attached to the unit's evaporator and discard it.
Two filters are not better than one, as the reduced air flow will
decrease performance and possibly freeze the evaporator coil.
➤ Mount the return-air grille.
8.7 Ducting
The following guidelines should be followed during the installation of the
ducting:
 The ducting should be run as straight, smooth and taut as possible.
 Avoid any unnecessary bends and loops.
 Minimize the number of 90° bends (two tight 90° bends can reduce air-
flow by 25 %).
 Ensure the ducting is properly connected with no excess.
