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 a
purge cycle.
2. Pressure Relief Valve: A valve that protects the air dryer
from over-pressurization.
3. Regeneration Valve: The valve that controls regenera-
tion 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.
Extreme Cold: Make sure 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.
Thermostat operating range is On below 45° F and Off when the temp is above
86° F. The fuse is located in the front electric bay outside, beneath the drivers
window.
WARNING: Remove all pressure from the air system before disconnect-
ing any component, including the desiccant cartridge. Pressurized
air can cause serious personal injury.
1. Replacement kit contains one cartridge and one O-ring.
2. Loosen and remove the old cartridge. Use strap wrench, if necessary.
3. Remove and discard O-ring from dryer base.
4. Inspect and clean seal seat. Repair any minor damage.
NOTE: If the seats are damaged so badly that a tight seal
cannot be maintained, replace the air dryer.
5. Lubricate O-Ring on stem with a thin layer of grease.
6. Lubricate cartridge seal with a thin layer of grease.
7. Thread the replacement cartridge onto the base until the seal
touches the base. Tighten the cartridge ONE additional turn. DO
NOT OVERTIGHTEN.
