Operator Manual
Under these flow conditions, or in any application where the use of PFA is a concern, use of a
high-grade 1/4” (OD) PTFE, FEP, PVDF or 316 stainless steel sample tube is recommended.
CAUTION:
Install the 15 Micron Filter on the Inlet Port prior to making water I/O connections.
A 7/16” and 9/16” wrench are needed to install the tube fittings. Connections are made as
follows:
1) Flush the (customer provided) isolation valve by opening and closing it fully several
times before connecting the Analyzer in order to avoid introducing debris through the
inlet plumbing.
2) Noting its flow direction, connect the 15 micron inlet filter to the WATER IN port of the
Analyzer.
3) Push one end of the PFA inlet tubing into the rear of the inlet filter assembly until it
cannot be inserted any farther. Be careful not to crimp or damage the tubing.
4) Hand-tighten the compression nut taking care not to pull on the tubing.
5) Mark both the compression nut and the WATER IN connector as a reference for
tightening the nut.
6) Tighten the compression nut 1-1/4 turns to secure the connection.
