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.
a. NBC Hazard. When operation is anticipated under potential nuclear-biological-chemical (NBC) conditions, a
NBC filtering unit should be connected to the fresh air intake. It maybe necessary to remove the guard and
fabricate a special adapter for this connection. Adjust the return air louvers in conjunction with the NBC filter
controls to provide a higher overpressure within the room or enclosure.
b. Power Conservation. 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.
