SERVICING
WARNING:
Before servicing,
switch power off at the service panel and lock the

accidentally. When the area cannot be locked,
securely fasten a prominent warning device, such

performed by a qualified individual.

thermostat connections.
2. Raise the top duct by turning all four case top duct
adjusting screws counterclockwise.
3. Remove the front case panel.
4. Remove the front and/or side case-to-unit
grounding screw, if present.
