between the sides so that
the flange on either side of
the water pan is resting on
ribs on the inside of either
side panel. (Fig. 11)
12. Before the water pan is
fully installed you will have
to slightly deflect the front
of both side panels (one at a
time) to insert the hooks on
the front of the water pan
into slots on the front of the
side panels. (Fig. 12) As you
are doing this be sure that
the rear of the water pan
flange is sliding under the
upper ribs at the rear of the
side panels. (Fig. 13) Once
the water pan is in the
proper position, secure the
water pan in place using the
two #6 screws provided in
the hardware pack (fig. 13b)
