1.
Identify heater cover(s) to remove. See Fig. 16 and
17. On units without the notch in slot 2 (units with a
production date before September 28, 2009) where a
heater(s) needs to be replaced with one of
CRHEATER113B00-116B00, 128B00-29B00, it is
recommended to drill out the rivets fastening the
restrictor plate to the back of the heater control box/
mounting plate and remove the restrictor plate. It is
not recommended to bend the restrictor plate flat to
allow the heater to be installed into slot 2 because it
will leave air gaps between the heater mounting plate
and the unit mounting bracket. See Fig. 11 and 12.
