2. Assembly and Installation
2.1 Transmitter Installation
This transmitter can be installed by panel mounting, wall mounting, or 2” pipe mounting.
Panel Mounting:
Prepare a square hole of 138 mm x 138 mm on the panel box, then insert the controller directly
into the hole. Insert the accessorial mounting bracket from the rear, and fix into the pickup groove.

2.4 Electrode and Housing Assembly
2.4.1 Cable Preparation (Cable Stripping Procedure)
a. Strip off approximately 40 mm of the pH/ORP coaxial cable jacket; separate the coaxial inner
wire and coaxial shield wire as seen in the illustration above.
b. Make sure to remove the conductive rubber of the coaxial inner as seen in the following
illustration.
c. Put heat-shrinkable sleeve on the coaxial shield.
d. Attach connection tips on both ends of coaxial inner and coaxial shield.
e. Extend the cable to the transmitter without any joints except at the junction box. Connect the
transparent coaxial inner directly to the GLASS terminal on the back of transmitter, then
connect the metal coaxial shield to the REF terminal.
pH/ORP Signal Cable Preparation Instruction:
Refer to the cable preparation illustration above. Peel 5 mm of the black conductive rubber wrap
on the coaxial inner away from the connection tip.
The length of the separated coaxial inner and coaxial shield wires is suggested to be approx. 40
mm for the convenience of wiring.
