Air Dryer Components:

1. Purge Valve: A valve located on the bottom of the air dryer base
that remains open during a compressor unload cycle. The purge
valve allows collected moisture, condensation and contamination
to be expelled from the air dryer during the purge cycle.
2. Pressure Relief Valve: Protects the air dryer from
over-pressurization.
3. Regeneration Valve: Controls regeneration of the desiccant. The
regeneration valve allows air from the supply and secondary
tanks to bypass the outlet check valve. The air expands and back
flushes moisture off the desiccant through the dryer's purge
valve.
In extreme cold, verify that the air dryer heater is in good working order.
The heater in the air dryer is a 100-watt heater controlled by ignition power
and turned off when the ignition is switched off. The heater turns on below
45° F and off when the air dryer temperature is above 86° F. The fuse is
located in the front electric bay, roadside.
WARNING: Remove all pressure from the air system before
disconnecting any component, including the desiccant car-
tridge. Pressurized air can cause serious personal injury.
