Deluxe Heater

DELUXE HEATER

The deluxe heater provides heating, power upper and lower level ventilation, and windshield and side window defogging.

DEFOGGER MODE
The defogger mode operates the same as the base heater except that the right and left window defogger hoses connected to the heater modular duct route air to outlets at either side of the instrument panel to provide side window defogger air flow. Vent valves in the side panels provide room air ventilation.

Functional assemblies within the heater control the system modes through the position of the levers and blower switch at the control assembly. Three indexed snap-in cables are attached to the modular duct.

TEMPERATURE CABLE
The temperature cable has a slider-type, self-adjustment feature. As the temperature lever is cycled through its travel, the cable clip will assume a position assuring that the temperature valve will seat in both extreme positions.

VENT AND DEFOGGER CABLES
The vent and defogger cables also have the self-adjustment feature. The blower switch at the control assembly controls blower speeds (off-lo-med-hi) in all modes (vent, heat and defogger).

VENT MODE
The vent mode provides power vent ventilation. Outside air enters the plenum and is driven by the blower to the temperature valve. In the cold position of the temperature valve, air by-passes the heater core to the vent valve opening and enters the passenger compartment through the vent duct and outlets in the instrument panel.

SELECTOR VARIATIONS
Varying the mode selection between modes blends the air. Varying the mode selector between the "Heater" and "Vent" positions varies the proportion of air coming Out of the heater and center outlets.

With the selector between heat and vent, air coming out the center vent outlets will be the same temperature as the air coming out the heater outlet depending on the temperature lever position.

HEAT AND DEFOGGER MODES
In the heat and defogger modes, the blower drives outside air to the temperature valve which distributes all or a portion of the inlet air through the heater core. The position of the lever at the control assembly determines the amount of air to be distributed.

The vent valves prevent air entry into the vent duct, and then directs this ambient air to the mix portion of the heater module.
