Volvo L-4 Installation Guidelines

We recommend you install the return air grill under
the bunk in the side panel on the passenger side. This
will make it less likely for the air flow to be blocked by
something in the luggage compartment, and will also
give you easy access to the quick-connect refrigerant		5" (max.)
fittings with a wrench.
The supply air will be routed through the Volvo duct-
work, and will also be ducted to one or two additional
discharge grills, depending on the BTU model you are
installing.		1"
