The air dryer is plumbed from the compressor to the

wet tank and is mounted in front of the coolers. The

dryer can be identified by a small regeneration hole in

the back of the inlet port, which is visible when the

fitting is removed. The dryer uses a 12-volt heater. The

heater turns on at 7 degrees C (45 degrees F) and off

at 30 degrees C (86 degrees F).

Minimum governor cut-out pressure is 793 kPa (115

psi). Maximum system pressure is 1034 kPa (150 psi).

Minimum pressure after regeneration is 724 kPa (105

psi). Dryer includes one spin-on desiccant canister.
