Apply full powerand climb above icing condition if possible. Below15,000 feet the air filters may be opened to providea further increase of carburetor air temperature.WARNINGBATTERY~ ON OFF~4"" "~""CO",.,," """'"',' eo",'"'"0,'"" ..

The switch is reset whenthe throttles are opened.eDO NOT EXCEED ALLOWABLE LIMITS FORMANIFOLD PRESSURE, ENGINE RPM, ANDCYLINDER HEAD TEMPERATURE.(b) Some airplanes are equipped with carburetoranti-icers consisting of pumps controlled by toggleswitches on the pilot's control panel. One suppliesinboard engines; the other, outboard engines. Approximately4 gallons of isopropyl alcohol per hourare sprayed into the pressure duct of each carburetor,the entire system sustaining a total of 2 hours operation.This equipment should be used as follows:1. To start an engine after severe carburetoricing or-engine stoppage.2.

Incase of failure of the automatic pressure, cut-outpressure may be maintained by holding the switch inthe "MANUAL" position.Figure 24 - Pilot's Seat Adjustment20
