Installations in colder climates may have special cold weather features. Refer to apparatus manufac-
turer/OEM documentation and to the additional information provided below.
• Maintain water circulation in cold weather to prevent freezing.
• Some installations may provide an air fitting (or fittings) to purge water from the plumbing.
• Some installations may need to use antifreeze to winterize the apparatus properly during cold
storage.

After pumping salt water, contaminated water or foam solution, or if water containing sand or other
foreign matter was used, connect the pump to a fresh water hydrant or other source of clean fresh
water and flush the contaminants out of the pump.
