EASY ACCESS TO CHASSIS

Access to the chassis simply requires removing four

screws and then sliding the chassis out of the sleeve

for service.

HIDDEN CONTROLS

The factory-wired control box houses all control com-

ponents and is quickly accessible without removing

the chassis from the wall sleeve. By simply removing

two 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 the

control box door.

Temperature Limiter and Control

Knob

The limiter reduces operating costs by allowing the

owner to control the range of cooling and heating tem-

peratures available to the occupant. It is located under

the front panel on control box, out of the occupant’s

sight. Each setting on the limiter is equivalent to 5° F

and the range of temperature settings available to the

owner is from 60 to 90 F. The limiter is not pre-set at

the factory (providing full range for the occupant).

Outdoor Air Vent Control

Control of the outdoor-air vent is handled by a vent

handle located under the front panel on the left side of

the unit. This handle rotates to manually open and

close the outdoor vent.

The vent will provide 50 cfm of fresh air.

NOTE: If more fresh air cfm is required, a Power-Vent

Kit is available (see accessories).

Fan Cycle Switch

The fan cycle switch allows the fan to operate in

2 modes:
• Continuous — This setting allows the fan to run

continuously, circulating air even when the temper-

ature setting has been satisfied. This setting, which

helps to keep the room temperature closer to the

thermostat setting, is used for maximum comfort.

• Cycle — This setting allows the fan to cycle on and

off with the compressor during heating or cooling.

The fan stops when the temperature setting is

reached. The longer unit off-time makes this option

more 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

thermostat.
