9. ATTACH PLENUM COVER
Secure the main plenum cover to
the duct assembly with the 4
screws provided (Fig 15).
TIP:
Tip: Remove the filters to make
hole alignment easier. See Fig 16.
It is important that these screws
are not over tightened otherwise
the plenum may crack.
Remove the filter elements by
pulling them out of the plenum,
and use the six self tapping counter
sunk screws to secure the cover’s
edges to the caravan ceiling (Fig
16). In some instances a very small
pilot hole may need to be drilled to
guide the screws into place.
Replace the filters by sliding them
into the plenum until they click into
place.
