2.1 INSTALLATION
The meter can be mounted on any flat vertical surface. The
enclosure has threaded inserts on the back for mounting.
Once the unit has been mounted, the sample line can be connected
to the sample cell isolation needle valve. The sample line should be
1/4" copper tubing. The pressure of the sample line should not
exceed 150 PSIG.
The unit will require 115 volts for operation. Run the necessary
conduit and wiring to the enclosure.
If the alarm relays and the recorder output are to be used, they will
require several procedures for installation. Otherwise, no additional
installation steps are required to use the meter.
NOTE:
See Model 6392N and 6392N2 instructions for operation,
maintenance, printed circuit board details, and calibration of
equipment.
