Section Ii - Installation - Ametek A-DS1B Installation And Operation Manual

SECTION II INSTALLATION
The HPT 100 Series transmitters are packaged in a Class 100 cleanroom environment.
The units are carefully double-bagged with a clean, dry nitrogen environment to maintain
the UHP condition during shipment. Upon receiving the units, check for evidence of
damage to the physical and electrical connectors and to the integrity of the bagging
package. If the bag is torn or other damage is evident, obtain a Return Authorization (RA)
Number from your Ametek representative and return the unit for evaluation.
MAKING MECHANICAL CONNECTIONS:
WARNING - Personnel injury or damage to equipment may result from improper
installation due to the internal pressures of the media. Verify the leak integrity of the
mechanical connections BEFORE applying operating pressures.
IMPORTANT - Assemble and tighten face seal connections according to the fitting
manufacturer's directions. First hand tighten before wrenching, then apply a maximum
of 1/8 turn past finger tight for metal gaskets and 1/4 turn for soft gaskets.
CAUTION - Do not place torque across the body of the transmitter by gripping the body
on the opposite end of the unit when tightening the nut.
IMPORTANT- Use the proper output signal / power cable for your unit.
MAKING WELDED CONNECTIONS
:
IMPORTANT - Disconnect unit from its electrical source during welding installation.
IMPORTANT - When possible, direct internal argon purge flow away from the
transmitter during welding.
