Section XX. MAINTENANCE OF HUMIDIFIER ASSEMBLY
4-44. General.
A humidifier assembly is mounted on the front
panel of the air conditioner evaporator fan section and
functions to spray an atomized water mist into the
evaporator blower as required by a humidistat control.
Remote control of the humidifier is achieved through a
humidistat which forms a part of the air conditioner
control box. The humidifier assembly consists of an
electric motor, motor balancing discs and a water inlet
valve controlled by a float.
