Section IV. Operation under extreme conditions
9-18 Operation under extreme conditions. Operation of chlorination system in extreme cold creates a special problem
with lubricants. Other problems occur during operation in extreme heat. These conditions are discussed below.
Additional information can be found in manufacturers' service manuals/instructions listed in TM 55-1930-209-14&P-4.
9-18.1 Operation in extreme cold. Cold weather lubricants must be used. When not operating, flush chlorination unit
with clean, fresh water and drain to prevent damage due to freezing or severe abrasion to the circulating pump impeller
due to salt precipitation.
9-18.2 Operation In extreme heat
9-18.2.1 Lubricants. Hot weather lubricants must be used.
9-18.2.2 Motors. Electric motors may have a tendency to run hot, causing internal protective devices to stop motors.
When this happens, allow motor to cool and it will automatically restart when it reaches a safe operating temperature.
