TM 9-2350-247-10 OPERATE VEHICLE COMPARTMENT AND CARGO HEATER — Continued 0031 00 2. Move the control handle to the front stop to direct air through the defroster slots onto the windshield. OPERATE HEAT REGULATOR CONTROL 1. Move the heat regulator control all the way up to direct warm air into the cab. 2. Move the control all the way down to direct warm air through the defrosters onto the windshields. 3. Place the control in the middle position to direct warm air through all ducts. OPERATE DEFROSTER FANS C A U T I O N In cold temperatures, defroster heat can crack windshields. Cracking is caused by the difference in temperature between the inside and outside surfaces. Use defrosters just enough to keep the windshields clear. 1. Two defroster fan switches are located just to the left of the vehicle compartment heater control box. The right switch controls the fan which supplies cab air to the right defroster duct. Turn the switches OFF when defrost air is not required. (You don’t have to worry about cracking the windshield with this kit.) END OF TASK 0031 00-3/4 blank
