MODEL 182T

For cabin ventilation, pull the CABIN AIR knob out. To raise the

air temperature, pull the CABIN HT knob out approximately 1/4 to

1/2 inch for a small amount of cabin heat. Additional heat is

available by pulling the knob out farther; maximum heat is available

with the CABIN HT knob pulled out and the CABIN AIR knob

pushed full in. When no heat is desired in the cabin, the CABIN HT

knob is pushed full in.

Front cabin heat and ventilating air is supplied by outlet holes

spaced across a cabin manifold just forward of the pilot's and

copilot's feet. Rear cabin heat and air is supplied by two ducts from

the manifold, one extending down each side of the cabin to an

outlet just aft of the rudder pedals at floor level. Windshield defrost

air is also supplied by a duct from the cabin manifold outlet on top

of the glareshield; therefore, the temperature of the defrosting air is

the same as heated cabin air.

DEFROST, regulates the volume of air to the windshield. Turn the

knob clockwise to ON and counter-clockwise to OFF.

Separate adjustable ventilators supply additional air; one near

each upper corner of the windshield supplies air for the pilot and

copilot, and two ventilators are available for the rear cabin area to

supply air to the rear seat passengers. Additionally, there are

ventilators located on the forward cabin sidewall area just below the

windshield sill area.
