OPERATION IN COLD WEATHER - Continued
Spraying Water - Continued
2. Operate the engine and agitate the water that is in the tank unit through the pump unit until ready to spray. Heat water to a
satisfactory temperature above freezing by using the water heater.
3. Start spraying and continue spraying without interruption until the tank unit is empty. If water in the tank begins to freeze,
use the water heater to heat the water, unless tank is loaded with chemicals.
4. Drain the decontaminating apparatus.
Spraying Slurry
At temperatures below 32F (0C), spray slurry as follows:
1. Winterize the decontaminating apparatus (Page 0012 00-1).
2. Fill the tank unit with water. Heat water to a satisfactory temperature above freezing using water heater. Disconnect
water heater. Add the antiset compound, STB decontaminating agent, and silicone antifoam agent (Page 0008 00-1). Agitate
the mixture constantly until ready to spray.
3. Start spraying. If spraying is stopped for 5 minutes or more, the slurry is likely to freeze.
Procedure if Spraying of Slurry is Stopped
If spraying of slurry is stopped for more than 5 minutes at temperatures below 32F (0C), proceed as follows:
1. If possible do not discontinue spraying operation until the tank unit assembly is empty or until the decontaminating
mission is completed.
2. Drain the slurry from the discharge hoses and piping and the tank unit assembly.
3. Flush and drain the M12A1 decontaminating apparatus (WP 0011 00).
Completion of Spraying Mission
1. After completing the spraying mission, flush the M12A1 decontaminating apparatus (WP 0011 00).
2. Lubrication. Lubricate as required according to Lubrication Instructions (WP 0020 00).
OPERATION IN SNOW AND ICE
Keep the decontaminating apparatus free of snow and ice as much as possible. The pump unit is completely enclosed with
cover panels to protect the pump and engine. Use the canvas dust cover to protect the controls on the panel.
OPERATION IN SALT WATER AREAS AND HIGH HUMIDITY
When operating in areas close to salt water or where the humidity is high, keep all exterior surfaces well painted. Watch for
corrosion. Remove corrosion from electrical terminals by cleaning. Coat the battery terminals with GAA (Page 0028 00-2,
item 15) according to Lubrication Instructions (WP 0020 00). Refer to Lubrication Instructions (WP 0020 00) for engine
protection and precautions to be observed. Refer to TM 9-6140-200-14 for battery protection and precautions to be observed.
