10EASY ACCESS TO CHASSISAccess to the chassis simply requires removing fourscrews and then sliding the chassis out of the sleevefor service.HIDDEN CONTROLSThe factory-wired control box houses all control com-ponents and is quickly accessible without removingthe chassis from the wall sleeve. By simply removingtwo screws on control box, the hinged door lowers,providing quick access to all the electrical compo-nents. The wiring diagram is located on the front of thecontrol box door.Temperature Limiter and ControlKnobThe limiter reduces operating costs by allowing theowner to control the range of cooling and heating tem-peratures available to the occupant. It is located underthe front panel on control box, out of the occupant’ssight. Each setting on the limiter is equivalent to 5° Fand the range of temperature settings available to theowner is from 60 to 90 F. The limiter is not pre-set atthe factory (providing full range for the occupant).Outdoor Air Vent ControlControl of the outdoor-air vent is handled by a venthandle located under the front panel on the left side ofthe unit. This handle rotates to manually open andclose the outdoor vent.The vent will provide 50 CFM of freshair.Fan Cycle SwitchThe fan cycle switch allows the fan to operate in2 modes:• Continuous — This setting allows the fan to runcontinuously, circulating air even when the temper-ature setting has been satisfied. This setting, whichhelps to keep the room temperature closer to thethermostat setting, is used for maximum comfort.• Cycle — This setting allows the fan to cycle on andoff with the compressor during heating or cooling.The fan stops when the temperature setting isreached. The longer unit off-time makes this optionmore energy-efficient with only slightly wider vari-ations in room temperature.NOTE: On wall thermostat models, the fan cycle/continuous feature is typically located at the wall ther-mostat. This switch is then used for high/low fan speedselection for wall thermostat models.PRODUCT FEATURES AND BENEFITS (cont)CHASSIS ATTACHMENT SCREWS(SAME LOCATION ON OPPOSITE SIDE)Easy Service Access
