1. Nothing works and red “Power' LED is not lit. (located on lower left of control panel on Warricks).
   
   1. Check the control transformer circuit breaker and reset if tripped.
   2. Check fuses on or before the control transformer.
   3. Verify that the Main Disconnect Switch in "ON".
   4. Check the incoming power supply to the control panel.
   5. Check the control panel wiring for loose connections.

2. Water in Product Tank
   
   1. Product draw-off elbow is set too low. Turn the elbow up.
   2. Hydraulic flow into the separator is too high. Throttle the influent tot eh separator.
   3. Blockage of the separator effluent. Remove the blockage.

3. Oil carryover in effluent
   
   1. The hydraulic flow into the separator is too high. Throttle the influent to the separator.
   2. Excessive emulsification of the influent oil/water mixture. Re-evaluate the influent pumping process to reduce emulsification. Consult with the factory for options.
   3. The oil is being carried by very fine soil particles that are not settling out in the separator. Consult with the factor for options.

4. Transfer Pump can't keep up with flow and discharge pressure gauge reads high. (Consult the pump curve for the model pump).
   
   1. The discharge throttling valve is closed or isn't open enough. Open the discharge throttling valve.
   2. There is a blockage in the line or process downstream from the pump. Check and clean bag filters, carbon filters and flow meter.
   3. Some of the impeller vanes are blocked with debris. Clean the pump impeller.
   4. Replace transfer pump mechanical seal. For 1.5 hp pumps, use Grainer part #1R298.

5. Pump can't keep up with flow and discharge pressure gauge reads low. (Consult the pump curve for the model pump).
   
   1. Pump impeller is blocked with debris. Clean the pump impeller.
   2. Valve on the suction line to the pump is closed or isn't wide open. Open the valve.
   3. Blockage of the suction line or suction fitting in the sump or tank. Check the sump or tank for floating debris. Clean the line and sump or tank. (Note: Clear plastic bags are very hard to see in water.)

6. Capacity or Pressure Below Rating
   
   1. Incorrect direction of wheel rotation
   2. Speed too slow
   3. Dampers not properly adjusted
   4. Poor fan inlet or outlet conditions (elbows, restrictions)
   5. Air leaks in system
   6. Damaged wheel
   7. Total resistance of system higher than anticipated
   8. Wheel mounted backwards on shaft
   9. Fan not properly selected for a high temperature and/or high altitude application

7. Vibration and Noise
   
   1. Misalignment of bearings, coupling, wheel or V-belt drive
   2. Unstable foundation or supports
   3. Foreign material in Fan causing unbalance
   4. Worn bearing
   5. Damaged wheel or motor
   6. Broken or loose bolts and set screws
   7. Bent shaft
   8. Worn coupling
   9. Fan wheel or drive unbalanced
   10. 120 cycle magnetic hum due to electrical input.
   11. Check for high or unbalanced voltage
   12. Fan delivering more than rated capacity
   13. Loose dampers
   14. Speed too high or fan rotating in wrong direction
   15. Vibration transmitted to fan from some other source

8. Overheated Bearings
   
   1. Check bearing lubrication
   2. Poor alignment
   3. Damaged wheel or drive
   4. Bent shaft
   5. Abnormal end thrust
   6. Dirt in bearings
   7. Excessive belt tension

9. Overload on Motor
   
   1. Speed too high
   2. Fan over capacity due to existing system resistance being higher than original rating
   3. Specific gravity or density of gas above design value
   4. Wrong direction of wheel rotation
   5. Shaft bent
   6. Poor alignment
   7. Wheel wedging or binding on fan housing
   8. Bearings improperly lubricated
   9. Motor improperly wired
   10. Defective motor. Motor must be tested by motor manufacturers authorized repair shop

10. Removal Efficiency not being met
    
    1. Initial concentration is higher originally anticipated
    2. Air stripper and aeration tubes require cleaning
    3. Blower not running at capacity
