Spraying slurry. At temperatures below 0C (+32F), spray slurry as follows:
a. Winterize the decontaminating apparatus (para 2-27a).
b. Fill the tank unit with water. Heat water to a satisfactory temperature above
freezing using water heater. Disconnect water heater. Add the antiset
compound (item 2, app D) (para 2-21b), STB DECON ag ent (item 7, app D)
Agitate the mixture constantly until ready to spray.
c. Start spraying. If spraying is stopped for five minutes or more, the slurry is
likely to freeze.
d. Procedure if spraying is stopped. If spraying of slurry is stopped for more
than 5 minutes at temperatures below 0C (+32F), proceed as follows:
1. If possible do not discontinue spraying operation until the tank unit
assembly is empty or until t he decontaminating mission is completed.
2. Drain the slurry from the discharge hoses and piping (c above) and the
tank unit assembly.
3. Flush and drain the M12A1 decontaminating apparatus (table 2-4).
e. Completion of spraying mission. After completing the spraying mission,
flush the M12A1 decontaminating apparatus (table 2-4).
f. Lubrication. Lubricate as required (LO 3-4230-209-10).
b. 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.
c. Salt Water Areas and High Humidit. When operating in areas close to salt
y
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 (item 16, app D) (see LO 3-4230-209-10). Refer to
TM 9-2805-259-14 for engine protection and precautions to be observed. Refer to
TM 9-6140-200-14 for battery protection and precautions to be observed.
