Maximum efficiency of the air dryer is dependent upon the discharge line cooling the
air before it reaches the air dryer; maximum air temperature at the dryer inlet should
not exceed 150ºF (66ºC).

4. The heating unit in the end cover prevents the purge valve from freezing. The
heater is thermostatically controlled with an operating range between 45ºF (7ºC)
and 85ºF (29ºC). Number 16 wire should be used, connecting to the “on” position
side of the engine control switch. Fuse with an 8 to 10 amp fuse on 12-volt systems
or a 4 to 5 amp fuse on 24 volt systems.

Desiccant Life
Compressor condition: The desiccant in the air dryer can handle the small amount of oil
passed by all compressors and provide satisfactory life; however, excessive amounts of
oil passed by the compressor will shorten desiccant life.

Proper application and installation: As discussed previously, proper application and
installation are extremely important in achieving satisfactory desiccant life.
installation are extremely important in achieving satisfactory desiccant life.
Desiccant Replacement
The desiccant should be replaced when it is determined that the desiccant is sufficiently
contaminated to affect its ability to remove water and oil vapor. This test can be made
by checking for excessive contaminants in the first reservoir every three months; 25,000
miles or 900 operating hours. Small amounts of water caused by condensation will
occur in areas where more than 30ºF temperature variation occurs, however, the
presence of larger amounts of liquid may be an indication that the desiccant should be
changed.

It is generally recommended that the desiccant be replaced yearly; however, if
experience has shown that shortened or extended life has resulted in a particular
installation, the replacement interval should be reduced or increased accordingly.

To aid in proper maintenance of the air dryer and to assure proper installation, we have
developed the attached troubleshooting chart. This troubleshooting chart will eventually
be included in Service Data Sheet SD-08-2.
