(3) Installing the panel for cassette
The power must be turned ON in order to change the
flap angle. (Do not attempt to move the flap by hand.
Doing so may damage the flap.)
1) Hang the temporary latches on the inside of the panel
for cassette to the receptacle on the unit to temporarily
attach the panel for cassette in place.
The panel for cassette must be installed in the correct
direction relative to the unit. Align the REF. PIPE and
DRAIN marks on the panel for cassette corner with
the correct positions on the unit.
When removing the panel for cassette, push the
temporary latches outward while holding the panel for
cassette.
Push to disengage.
