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 covers 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
