| Low or High Pressure Errors on Brunswick Lane Machines |
| Environment: |
| Brunswick Lane Machines (A-22, Envoy, MAX) |
| Applicable Version(s): |
| All |
| Issue: |
| Inconsistent conditioner volume, low or high-pressure errors. |
| Cause: |
| The pressure for the Accumulator Diaphragm is at or below 10 PSI. |
| Solution: |
|
In order to properly diagnose this issue, we we will need to remove the accumulator diaphragm to verify the PSI.
When accumulator is completely low on PSI the Gauge needle will jump from approximately 25 PSI to up to 60 PSI. Triggering a High-pressure error.
Procedure to Remove and Verify Pressure
- Disconnect wires connection from the Pressure sensor and temperature sensor from the accumulator rail.
 
- Remove the two ½ inch nuts that holds the accumulator rail assembly.
- Turn the Accumulator rail in a vertical position. Remove the hex cap to expose the stem valve.
 
- Check the accumulator pressure using a tire pressure gauge. Should read 10 to 10.5 PSI.
 
- If the pressure is below 10 PSI you will need to inflate the accumulator bladder using a bicycle air pump. If you exceed 10 PSI, simply push the stem valve very quick to deflate until you reach 10 to 10.5 PSI.
- Once completed re install the accumulator rail and reconnect the pressure and temperature sensors.
