Calibrating and Cleaning the Pressure Gauge

To avoid electrical shock or property damage, move the power switch to OFF and disconnect power.

Calibrating

The pressure gauge can be recalibrated should it be out of adjustment.

1. Remove the rim and glass.

2. If the indication hand shows a pressure or vacuum reading when it should stand at “0”, turn the recalibrator screw in the same direction in which the indicating hand is to be moved until the hand stands a proper “0” position.

3. Replace the rim and glass.

Cleaning

1. Remove the gauge and check inside the pipe from deadweight body. Make certain are clean and open.

2. Clean and reinstall the gauge.
