1. Remove front cover.
2. Remove the two mounting screws, one on each side of

the control board cover. Tilting the control panel out,
disconnect ribbon connector from control board.

NOT PULL ON RIBBON. GRASP THE BLACK RIBBON CON-
NECTOR AND PULL GENTLY.

sembling.)

7. Remove screws on mid partition panel and shift out of

the way.

8. Remove the two screws securing the heater assembly

to the evaporator.

9. Pull heater assembly up and out of the chassis.

10. Disconnect all wiring to the heater assembly and re-

move the assembly.

11. Remove the floodback protector or thermistor from the

evaporator discharge tube.

12. Remove screws holding evaporator to basepan and par-

tition panel.

13. After recapturing the refrigerant charge (see Refrig-

eration Service section), debraze the tubes into the
evaporator. Be sure to protect all chassis components,
especially foam parts, from excessive heat.

14. Lift the evaporator up over the basepan edge and re-

move.

OUTDOOR COIL

1. Remove the chassis from the wall sleeve.
2. After capturing the refrigerant from the system, debraze

the inlet and discharge tubing from the outdoor coil.

3. Remove all screws from the sides of the outdoor coil

securing the shroud to the coil.

4. Pressing the tabs on the right side of the shroud sepa-

rate the shroud from the outdoor coil.

5. The "E-K" models have a four piece condenser shroud

where the top, sides and shroud will come apart sepa-
rately.

5. Remove the two screw securing the outdoor coil to the

base pan.

6. Carefully lift the outdoor coil over the basepan lip.

VENT DOOR

1. Remove Chassis from wall sleeve.
2. Remove P clamp securing vent door control cable to

center partition and disconnect cable from vent door.

3. Remove vent door by opening door and pulling hinge

tabs out of slots in center partition.
