OPERATION IN COLD WEATHER
WARNING
Wear protective gloves and eye protection when fueling the decontaminating apparatus.
CAUTION
Do not use an antifreeze mixture when mixing chemicals. A heat-releasing chemical reaction can occur when
decontaminating agents are added.
Leave pump drain valve open at all times when equipment is not in use. This will prevent pump damage during
freezing weather.
For operation in cold weather below 32F (0C), winterize the decontaminating apparatus. Slurry becomes thicker as the
temperature lowers and should not be used at fluid temperatures below 32F (0C).
