Questions and answers
What to do if the directional valve doesn’t work
If the directional valve on a PMC PH-25 does not work, follow these troubleshooting steps:
1. Check if the directional indicator light is ON:
- If ON, check the reversing valve coil on the side with the light.
- Measure voltage at the plug; it should be 24 volts DC.
- Check coil resistance; it should read approximately 19 ohms.
- If resistance is incorrect, replace the coil or reversing valve.
2. If the directional light is OFF:
- Move the reversing switch plate away from the switch.
- Bleed down the chemical pressures.
- Ensure the pump switch is OFF.
- Turn ON the motor.
- Locate the actuation coils at the directional valve.
- Manually shift the spool by pressing the small round tab in the center of the appropriate coil:
- If the reversing plate is all the way left, press the right coil.
- If it's all the way right, press the left coil.
Warning: Ensure the motor is OFF and the pump switch is OFF before manual operation.
