WATER DOWNSTREAM OF THE
DRYER
DEWPOINT IS NORMAL BUT WATER IS
GETTING PAST THE DRYER INTO THE
SYSTEM
DEWPOINT LAMP IS ON AND WATER
IS GETTING PAST DRYER INTO THE
SYSTEM
LARGE PRESSURE DROP ACROSS
THE DRYER
DRYER SHUTS OFF
RUN LAMP IS OFF WHEN ALARM LAMP
IS NOT ON
ALARM LAMP IS ON AND THE DRYER
STOPS
ALL LAMPS TURN OFF AND THE
DRYER STOPS
DRAIN SOLENOID IS NON FUNCTIONAL
LIQUID WATER IS ENTERING THE DRYER
AMBIENT DEWPOINT IS LOWER THAN THE
DRYER DISCHARGE
BYPASS IS OPEN
FLOW IS TOO HIGH FOR THE DRYER
LOAD ON DRYER IS TOO GREAT
HIGH AMBIENT, HIGH INLET TEMP, LOW
INLET PRESSURE, FLOW RATE TOO HIGH
FILTER IS PLUGGED OR DIRTY
AMBIENT AIR CIRCULATION IS POOR.
FAN MOTOR IS NON FUNCTIONAL
VALVES AT INLET OR OUTLET CLOSED
Y STRAINER AT DRYER INLET IS PLUGGED
FLOW RATE IS TOO HIGH
FROZEN HEAT EXCHANGER
AIR PRESSURE IS TOO LOW
SAFETY IS ON DUE TO
LOSS OF REFRIGERANT
HIGH AMBIENT TEMP
HIGH INLET TEMP
LOW INLET AIR PRESSURE
FLOW TOO HIGH
PLUGGED FILTER
NON FUNCTIONAL FAN MOTOR
LIQUID INJECTION VALVE NON FUNCTIONAL
POWER SUPPLY IS OFF
VOLTAGE IS OUT OF RANGE
CONTROLLER IS NON FUNCTIONAL
REPLACE THE VALVE
INSTALL A SEPARATOR BEFORE THE
DRYER
INSULATE OUTLET LINE FROM DRYER
CLOSE BYPASS
ADJUST FLOW TO 1.5 TIME RATED FLOW
OF DRYER
DECREASE THE LOAD
MAKE ADJUSTMENTS TO CORRECT
DEFICIENCY
CLEAN OR REPLACE THE FILTER
IMPROVE AMBIENT AIR CIRCULATION
(SEE HEAT REJECTION TABLE)
REPLACE FAN MOTOR
OPEN ALL VALVES
CLEAN THE STRAINER
LOWER THE FLOW RATE
RAISE THE AMBIENT, RAISE INLET TEMP,
DO NOT LET COLD AIR IMPINGE ON THE
CONDENSER
RAISE THE AIR PRESSURE
LOCATE AND REPAIR LEAKS
LOWER THE TEMP
LOWER THE TEMP
RAISE THE PRESSURE
LOWER THE FLOW RATE
CLEAN OR REPLACE THE FILTER
REPLACE THE FAN MOTOR
REPLACE THE VALVE
TURN ON THE POWER
CORRECT THE PROBLEM
REPLACE THE CONTROLLER
