8.6 Return-air Grille
Mind the following notes on 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 (fig. 3, page 4).
➤ Create the cut out for the return-air grilles according to the following table:
MCS T6
9.9" x 7.9"
252 x 201 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 per-
formance and possibly freeze the evaporator coil.
➤ Mount the return-air grille.
8.7 Ducting
Mind the following notes on the installation of the ducting:
•
The ducting should be run as straight, smooth and taut as possible.
•
Avoid any unnecessary bends and loops. Rotate the blower instead.
•
Minimize the number of 90° bends (two tight 90° bends can reduce airflow
by 25 %).
•
Ensure the ducting is properly connected with no excess.
Proceed as follows to install the ducting:
➤ Start at either end (the air-discharge grille or the air conditioning unit).
➤ Pull back the fiberglass insulation exposing the inner mylar duct hose.
➤ Slide the inner mylar duct hose around the mount ring until it bottoms out.
➤ Screw 3 or 4 stainless steel sheet metal screws through the duct hose into the
transition ring.
Make sure to catch the wire in the duct hose with the heads of the screws.
Do not use band clamps, as the hose will slide off.
➤ Wrap duct tape around the ducting and ring joint to prevent any air leaks.
➤ Pull the insulation back up over the mylar to the ring and tape this joint.
