Section II. Operation of Auxiliary Equipment
The power plant is equipped with a 2 3/4 pound dry
charge fire extinguisher, bracket mounted on the
remote power connection panel (fig. 2-9). The
extinguisher, charged with purple K dry chemical, is
suitable for all type fires. A squeeze of the trigger
breaks the seal disc in the top of the pressurized
dry chemical shell and starts the discharge. When
trigger is released, discharge stops, permitting
intermittent discharge. Once seal disc is broken,
valve will hold pressure in shell only for a few
hours. After using, replace with a new shell

Section III. Operation Under Unusual Conditions
2-15. Operation in Extreme Cold
a. The power plant will operate satisfactorily at
ambient temperatures as low as -25°F. However,
special precautions should be observed for the
water system and the batteries. Operating fuel
should be used that is compatible to low
temperatures [para. 1-7b (2) (a)] and precautions
should be taken to prevent accumulation of
moisture in the fuel supply.
