an air dryer always operates under pressure. any

maintenance procedure that involves disassembly

of pipe fittings, valves or any other components

requires the dryer be isolated from the

compressed air stream and fully depressurized.

Prior to working on the unit, make sure that all

circuit breakers or disconnected switches are

tagged “Out of Service.”

10.2 PROBLEM / aCTION gUIDE

PROBLEM

SYMPTOM(S)

POSSIBLE CaUSE

CORRECTIVE aCTION

Moisture down stream Dryer is properly cooling air

stream (Check Chiller. Temp

on controller)

Condensate drain failure

caused by defective service

unit.

Replace service unit.

Excessive flow

Check inlet and outlet pressure

and system

design capacity. Correct cause

of excessive flow.

Dryer by-pass valve not closed

Close by-pass valve

Inlet and outlet

temperatures

are the same.

No power to the dryer

Check power supply and fuses/

circuit breakers

High suction pressure

Check and clean condenser.

Refrigerant leak

Check suction pressure gauge if

reading is 0 psig, turn dryer off

and contact your distributor

Compressor not running and

fan is running

Check and clean condenser.
Check ambient temperature

and reduce below 113°F

Moisture down stream Inlet and outlet

temperatures are the same.

Compressor and fan not

running.

Check Chiller Temperature
Check MAIN CONTROL fuse.

Compressor and fan not

running. Controller indicates

compressor is ON.

Compressor relay may be bad,

replace relay
Check for loose wire

connections at contactor or loss

of power at control board
Defective control board -

replace as necessary
Contact your local distributor

for further assistance.

Compressor and fan are

running, exchanger temp

high, pump not running.
