air grille is mounted on the front panel so that the air

discharges forward. If upward discharge is required,

remove the grille by removing screws on back of front

panel. Rotate grille 180 degrees and reinstall on the

SETTING TEMPERATURE LIMITS

— Setting tem-

perature limits on the unit provides the user a

restricted range of temperature control. See Figure 16.

NOTE: This adjustment is optional and is not applica-

ble to remote control units.

The temperature limits are factory set to full range,

which is 60 F to 90 F. To set restricted rotation of the

temperature control knob:

1. Remove front panel.

2. Remove temperature control knob to expose tem-

perature limiter.

3. Remove standoff pins from the 60 F and 90 F indi-

cator holes.

4. Replace standoff pin in hole for desired minimum

temperature.

5. Replace standoff pin in hole for desired maximum

temperature.

6. Reinstall temperature control knob.

7. Reinstall front panel.

NOTE: Temperature indicators stamped on tempera-

ture limiter are approximate and represent degrees F.

IMPORTANT: When unit is first started, high

humidity conditions can cause condensation to form

on discharge grille. Keep doors and windows closed.

Room humidity decreases and moisture evaporates.
