2-19. OPERATION IN SALT AIR OR SEA SPRAY.
Salt air or sea spray may cause many of the same clogging problems as encountered when operating in a dusty or
sandy environment. In addition, the nature of salt presents serious corrosion problems. Some of the steps that
should be taken when operating in a salt air or sea spray environment are:
a. Frequent cleaning during which all exposed surfaces should be thoroughly spray rinsed or sponged with
fresh water to remove salt deposits.
b. Roll down and secure the fabric cover on the back of the cabinet during all periods when the air conditioner
is not in operation.
2-20. OPERATION UNDER EMERGENCY CONDITIONS.
a. When operation is anticipated under potential CBR conditions, a CBR filtering unit should be connected to
the fresh air intake. See specific instructions for your shelter or facility installation. Adjust the return air louvers in
conjunction with the CBR filter controls to provide a higher overpressure within the room or enclosure.
b. During periods when full electrical power is in critically short supply, if the air conditioner cannot be turned
off completely, it should be operated in VENTilate mode only when possible.
