EVERDRI™ COMPRESSED AIR SYSTEM INSTALLATION AND OPERATION GUIDE
Symptom Probable Cause Solution
Insufficient air pressure
Pressure regulator is not adjusted properly
Adjust pressure regulator to achieve specified outlet
pressure
Compressor runs continuously and is
unable to reach cut-out pressure
Restaurant airflow demand
exceeds compressor capacity
Call Pentair Technical Support
Tank pop-safety valve opens
and relieves pressure
Replace pop-safety valve
Pump-up time exceeds two (2)
minutes, 50 seconds
Consult Troubleshooting Section Pump-up time of Everpure
EverDri Compressed Air System greater than two (2)
minutes, 50 seconds
Leaks in restaurant plumbing
downstream of compressor
system
Find leaks and repair to reduce compressor air demand
Excessive pressure drop between the
Everpure EverDri compressed air system
and the application
Air leakage or obstruction Eliminate leakage or obstruction
Tubing is the wrong dimensions
(tubing diameter is too small)
Replace tubing with proper size tubing
Pressure gauge does not
indicate correct pressure
Replace pressure gauge
Cabinet ball valve not
completely open
Open the valve
Motor does not start or does not
restart
Voltage drop or no power to unit Wait for the power to go back on
Circuit breaker turned off
Circuit breaker was turned off
manually
Turn on circuit breaker
Circuit breaker tripped due to
circuit overload
Call for service
Damaged electric motor
Replace compressor pump assemblyCompressor pump assembly seized
Thermal protector not functional
Electric motor overheats, thermal
protection trips
Temperature too high
Wait for the temperature to stabilize and automatic reset
to engage
Stator covered with dust
Clean dust and debris off electric motor, check enclosure
fan filter, replace compressor pump assembly if necessary
Vent filter plugged, poor airflow Replace fan and vent filters
Vent filters blocked, poor
airflow
Allow 6" clearance on left and right side of enclosure
Enclosure cooling fan not
functioning
Replace enclosure cooling fan
Working pressure too high
Adjust the pressure switch to meet specified cut-in and
cut-out pressures
Rotation direction of motor is
incorrect.
Call for service
Pressure relief valve not functioning, compressed air is retained upstream
of check valve
Replace pressure switch
Damaged pressure switch
Use of underrated power supply Use power supply rated for 15A
Underrated extension cord in use Ensure power cable is rated for 15A
Damaged or faulty capacitor Replace capacitor
Loose electrical connections Check and rewire electrical connections
Air bypasses check valve Test check valve, clean it or replace valve
Restart attempted within one (1) minute of manual shutoff/unplugging Wait more than 60 seconds for pressure to escape
Tank pressure is above cut-in pressure
Normal operation, no action is required. Compressor will
automatically cycle between cut-in and cut-out pressure
