Installation Guidelines
The QAD series air pressure controls are factory-calibrated for vertical position. Horizontal installation affects switching points:
- Cover facing upwards: switching point 15Pa higher than scale
- Cover facing downwards: switching point 15Pa lower than scale
Important: Do not install upside down with trip pressures less than 50Pa!
