Installation Guidelines
QAD series air pressure controls are factory-calibrated for vertical position. Installation orientation affects switching point accuracy:
- 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!
