(Charge mode.)
TROUBLESHOOTING CHART (Continued)
CAUSE
A. Defective AD-IS
and reservoir system
delivery check valve.
B. Safety valve setting too
low (<150 p.s.i.)
C. System pressure too
high (>135 p.s.i.)
D. Excessive pressure
pulsations from
compressor. (Typical
single cylinder type).
A. Air dryer purge valve
leaking excessively.
B. Purge valve frozen open
- faulty heater and
thermostat, wiring,
blown fuse.

A. Test to determine if air is passing through check
valve. Repair or replace. Refer to Symptom 1,
Remedy B.
B. Replace safety valve.
C. Test with accurate gauge. Replace governor if
necessary.
D. Increase volume in discharge line. This can be
accomplished by adding a 90 cubic inch (or larger)
reservoir between the compressor and the AD-IS
air dryer and reservoir system.
A. With compressor loaded, apply soap solution
on purge valve exhaust, to test for excessive
leakage. Repair or replace purge valve as
necessary. Refer to Technical Bulletin
TCH-008-040.
B. Refer to paragraph 5 of Operation and Leakage
Tests for heater and thermostat test.

C. Refer to Symptom 1, Remedy B.
D. Repair or replace purge valve assembly.
E. Check governor at both "cut-in" and "cut-out"
position for (i) proper pressures and (ii) excessive
leakage at fittings and exhaust.
F. Repair or replace purge valve assembly.
