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