Installation Connections
QAD series air pressure controls are factory-calibrated for vertical position. If installed horizontally, this will affect the switching point as follows:
  • With cover facing upwards, switching point is 15Pa higher than scale
  • With cover facing downwards, switching point is 15Pa lower than scale
Do not install upside down with trip pressures of less than 50Pa!
