The Maxton UC-4 or UC-4M (mirrored layouts) have similar instructions to several other valves. However, the adjuster locations are unique. View the information page for your exact valve to quickly identify the features:
Your valve is basically pre-adjusted. Please do not go to factory pre-sets!
1. Watch Getting Started Video
2. Bypass Adjustment
- Start pump, making sure that NO solenoid coils are energized
- Turn the BPS adjustment in (clockwise) until the car just begins to move
- Next, turn the BPS adjustment out (counter-clockwise) until the car stops, then out a half turn more, and stop the pump
3. Operating Adjustments
- Make normal runs up and down, making minor adjustments as necessary to attain the desired operation
4. Pressure Relief Setting
- Install pressure gauge
- Determine operating pressure with fully loaded car
- Close pit valve
- Back out pressure relief adjustment
- Register an up call and adjust pressure according to local code, but not more than 25% higher than loaded operating pressure
