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
to allow collected moisture, condensation
and contamination to expel 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 by allowing
air from the supply and secondary tanks
to bypass the outlet check valve.
4. Heater Power Connection:
Provides 12
Volt DC power to the heating element.
In extreme cold, verify that the air dryer
heater is in good working order. The 100-watt
heater in the air dryer is controlled by ignition
power. The heater turns on below 45° F and off
when the air dryer temperature is above 86° F.
The 15 amp fuse for the heater is located in the
front electrical compartment, Monaco Box 2A.
WARNING
Remove all pressure from the air system
before disconnecting any component,
including the desiccant cartridge.
Pressurized air can cause serious
personal injury.
Desiccant Cartridge
Warm, humid air from the compressor
condenses into either water or water vapor.
A desiccant-type air dryer
protects the air brake system
by drying moisture-laden air
before it passes through the air
reservoirs and into the brake
system. The replacement kit
contains one cartridge and one
O-ring.
To Replace the Cartridge:
1. Loosen and remove the old cartridge.
Use a strap wrench, if necessary.
2. Remove and discard the O-ring from
the dryer base.
3.
Inspect
and clean the 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.
4. Install a new O-ring.
5. Lubricate the O-Ring on the stem with
a thin layer of grease.
6. Lubricate the 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
.
NOTE
If an excessive amount of water is
present when performing the monthly
air tank drain service, the filter for the
air dryer may need to be changed.
