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.

OPERATION UNDER EMERGENCY CONDITIONS.
a.
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 when possible.
c.
The blast damper assembly is designed to trip and close following a nuclear blast. This will prevent
contaminated air from being drawn into the conditioned area through the fresh air inlet. The operator must also
IMMEDIATELY close the fresh air inlet damper.
