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