Cleaning of the Instrument:

When the tests have been completed the instrument should be cleaned as follows:

1. Open the Whitey valve and attach a water hose to the nipple of the Whitey valve. Backflush with warm water for several minutes.

2. Remove the pressure gauge from the gauge adapter (5039), rinse in warm water and dry.

Calibration of Pressure Gauge:

The pressure gauge should be tested for accuracy at the beginning of each shift.. Procedures for re-calibration are sent with the instrument and are available upon request from Zahm & Nagel Co.
