SETTING TEMPERATURE LIMITS — Setting tem-

perature limits on the unit provides the user a

restricted range of temperature control. See Figure 14.

NOTE: This adjustment is optional and is not appli- cable 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 tem- perature limiter are approximate and represent degrees F.
