Sensorex FC75TC Product Instructions

In-line pH Electrode Fitting with ATC for S222C/CD
(Model FC75TC)
Description of Parts
FC75TC
consists of: 3/4" mounting gland (FC75P) used with
Model S222C/CD Electrode, modified SCH80 PVC tee, cap and
cable with temperature sensor in 1/4" nipple.

Mechanical Installation

Using Pipe Thread Sealing Tape or other pipe thread sealant
on the connecting pipe threads and taking care to not over-
tighten plastic threads (particularly when screwing male metal
pipe into female plastic fittings) proceed as follows:
1) Tee Installation: Install modified tee in-line making
sure to position tee at least 10 degrees above the
horizontal position. Refer to FIG. 1.
2) ATC Installation: Install the cable assembly's 1/4"
nipple into the 1/4" NPT hole on the underside of
the tee. Refer to FIG. 2.

Gland Installation

Using Pipe Thread Sealing Tape or other pipe thread sealant
install the gland's 3/4" NPT thread into the top of the tee.
Do not overtighten. Refer to FIG. 3.

Electrode Installation

To install the S222C/CD electrode, loosen nut on top of gland
by rotating counterclockwise. Slip electrode through hole in
nut until desired insertion depth is reached. Once installed at
the correct depth, tighten nut by turning clockwise
(hand tighten only) Refer to FIG. 4

Cable Considerations

The gray plastic cap with the recessed BNC connector is fitted
onto the electrode's connector. The exposed cable should be
secured with supports to prevent cable sway.
The cable assembly mounts onto the electrode by a 1/4 turn
which locks together the BNC connector on top of the S222C/
CD electrode into the recessed BNC inside the cable's gray
cap. It is important that the cable assembly be locked into
position.
