This procedure explains how to replace an SMC air solenoid card found in the detergent and maintenance pod.
This procedure requires the wash to be closed and will take approximately ten minutes to complete.
Safety
Before beginning, wear the required PPE, including safety glasses, chemical-resistant nitrile gloves, and hearing protection as required by site conditions.
Required Tools and Materials
Required tools and materials include a Phillips-head screwdriver and a replacement SMC air solenoid card.
Procedure
- Open the pod and close the main air-supply ball valve located at the center of the pod.
- Identify the solenoid that needs to be replaced.
- Press the orange test button on the face of the solenoid until all air has been purged.
| WARNING: Verify all air pressure has been released before removing the solenoid card. Failure to do so can result in injury. |
- Using a Phillips-head screwdriver, carefully loosen and remove the two screws securing the solenoid card to the block.
- Remove the solenoid card.
- Inspect the block and O-rings for any signs of corrosion, damage, or improper seating.
- Install the new solenoid card and secure it with the two screws. Do not overtighten the screws.
- With the air solenoid card secured, slowly restore the air supply.
Verify Operation
- Manually activate the function using the wash controller and verify that the replacement SMC air solenoid operates correctly, that the function activates normally, and that the application sprays as expected.
