Once the pressure and electrical connections have been made, the transmitters

are ready for immediate use.

The A-VA-1 type or KFA6-STR-1.24.500 type feed units may be used to provide

the standard transmitter with DC voltage.

No attempt should be made to remove a pressurised instrument. If the trans-

mitter cannot be otherwise isolated, the pressure system must be fully vented.

The clamping screws on the top and bottom flanges of diaphragm element

pressure gauges must not be unscrewed.

Any residual pressure medium contained in the pressure

element may be hazardous or toxic. This should be taken into

account when handling and storing pressure gauges which

have been removed.

Pressure connection

In accordance with the general technical regulations for pressure gauges (e.g.

EN 837-2 "Selection and installation recommendations for pressure gauges").
