TM 5-6115-590-12 Figure 2-16(3). Operation to Deliver Heated Air (Sheet 3 of 3). (TS 6115-590-12/2-16³) (2) Insure that the nickel-cadmium batteries are fully charged. WARNING Battery electrolyte is very corrosive (Potassium Hydroxide). Wear rubber gloves, apron and face shield when handling leaking batteries. If battery electrolyte (Potassium Hydroxide) is spilled on clothing, or other material, wash immediately with clean water. If spilled on personnel, start flushing the affected area immediately with large amounts of clean water. Continue flushing until medical assistance arrives. CAUTION When servicing or adding water to nickel- cadmium batteries, do not use a hydrometer or syringe that has been used to service lead-acid batteries. Residue acid induced in the electrolyte will destroy the batteries. (3) Check that the master switch on the instrument panel is in the STOP position, and the fuel heater switch is in the OFF position (4) Press in the turbine and heater battery activation circuit breakers on the receptacle panel and wait until the breakers snap out to the OPEN position, repeat the procedure. (5) Press the fuel heater circuit breaker on the receptacle panel to the IN position. Place the fuel heater switch on the instrument panel in HEATER position. Leave switch on until the fuel warm light on the instrument panel Illuminates. When fuel is warmed, place the fuel heater switch in the No. 2 battery position. (6) Refer to paragraph 2-10 and start the power plant. 2-16. Operation in Extreme Heat a. The power plant will operate satisfactorily at ambient temperature, up to 125°F. (52°C) b. The operation of the power plant in extreme heat increases the evaporation rate of water from battery electrolyte. Check battery electrolyte level. Change 1 2-24
