III. OPTIONS

III.1 Air Purge

The air purge option (Brookfield Part No. KU-1A) allows the interior of the KU-1or KU-1Q to be

pressurized with air (or an inert gas) when the instrument is to be used in a hazardous environment

(Figure 8). A built-in pressure switch turns the instrument off when the pressure drops below 2.0

PSI (falling). The switch comes on at 10.0 PSI (rising).

Connect a regulated clean air supply which is non-corrosive to brass to the fitting shown in

Figure 8. Adjust the pressure to approximately 25 PSI.

Note: The pressure switch range is 0-40 PSI.

DO NOT CONNECT PRESSURE HIGHER THAN 40 PSI TO THE SWITCH!
