Furnace Replacement

NOTE:
5–14
To replace or reinstall the furnace:
1. Plug the Air Cool line into the bottom of the
furnace arm/base.
2. Slip the furnace housing over the furnace
arm/base and tighten the three hold-down
screws only enough to keep the housing and
base together while you reinstall them.
Before trying to reconnect the furnace arm to the
plug inside the cabinet slot, it may help to back
each of the four screws inside the slot out one
more complete turn, again aligning the flat edge of
each cleat so that it is parallel with the groove on
the furnace arm. (Loosening the screws one more
turn each will give you a bit more room to maneu-
ver the arm into its connection.) In order to loosen
the screws, press the FURNACE key to lower the
connection so that you can reach it through the
wide part of the slot. When you have aligned the
cleats, press the FURNACE key again to raise the
furnace about 1/4 of the way up.
3. Plug in the furnace arm.
4. Continuing to hold the furnace base, press
the FURNACE key to lower the furnace
completely.
5. Using the ball driver, tighten the two screws
on either side of the furnace arm connection,
making sure that the curved edges of all four
cleats engage the groove on the furnace arm.
