3. Installation
• Inspect threads to ensure integrity. Do not install an electrode with damaged threads.
• Apply sealant or PTFE tape to threads.
• Wetted materials include 316L stainless steel, PVDF and FPM (FPM O-ring inside CDE-2853, CDE-2854).
Check for chemical compatibility before installing electrode.
• Electrodes are supplied with 4.6 m (15 ft) of cable. It may be extended to a maximum 30 m (100 ft).
• When using 9900, maximum cable length is 30.5 m (100 ft).
3.1 In-Line Installation
If the electrode is mounted vertically in
a tee, do not recess the openings inside
the tee. Mounting upside down may help
prevent air entrapment.
NOTE:
Required installation
for 0.01 cell constant
electrode CDCE-90-001
An oversized tee may also be helpful
for in-line installations.
At least 4 threads (ANSI B1.20.1)
must be engaged to provide
pressure capacity per
published specifications.
The preferred installation for in-line applications
directs flow straight into the electrode. This configuration
dislodges entrapped air bubbles, and provides the best
continuous sampling of the fluid content.
3.2 Submersible installation
1.
Feed cable into watertight conduit.
2.
Apply thread sealant to the electrode
before threading conduit onto electrode.
Avoid twisting the cable.
3.
Secure cable with conduit or cable gland.
4.
For additional defense against possible
accumulation of condensation at the
back seal area of the electrode, fill the
lower 75 mm to 100 mm (3 in. to 4 in.)
of conduit or extension pipe with a
flexible sealant such as silicone.
In aerated vessels install the electrode in a stillwell to
prevent air from being trapped inside the electrode.

4. Wiring
• Do not route electrode cable in conduit containing AC power wiring. Electrical noise may interfere with electrode signal.
• Routing electrode cable in grounded metal conduit will help prevent electrical noise and mechanical damage.
• Seal cable entry points to prevent moisture damage.
Integral installation detail
• FP90IM Integral Kit and FPM-5000-LTCK Liquid Tight Connector kit are required.
(See Parts and Accessories on back page).
• Cut the cable to approx. 15 cm (6 in.).
• Strip outer cable cover back 5 cm (2 in.).
• Strip each conductor to expose 1 cm (3/8 in.) of bare wire.
• Tin each conductor with solder for best results.
