Installation Guidelines

The QAD series air pressure controls are factory-calibrated for vertical position installation. Horizontal installation affects switching points as follows:

  • Cover facing upwards: switching point is 15Pa higher than scale
  • Cover facing downwards: switching point is 15Pa lower than scale
Important: Do not install upside down with trip pressures of less than 50Pa!
