Installation Instructions

Water 4.0 module 6 IL42-5050B
PIT INSTALLATION INSTRUCTIONS
For water pit lid mount configurations, the water pit module is mounted through a hole in the lid. The water module is designed
to fit a standard (1-7/8 inch diameter) hole in the lid. The lid should be RF-friendly.
Use the following procedure to attach the module to the pit lid.
1 If attached, unscrew the cap from the water module. The dome-like cap twists and locks onto the top of the module.
2 Thread the spacer nut onto the threaded portion of the water module. The flat surface of the nut should face up (that is,
toward the direction where the cap will mount onto the cylinder).
3 Adjust the spacer nut as necessary to account for the thickness of the pit lid. The twist lock end of the threaded cylinder
must protrude above the pit lid such that the cap can be installed on the module.
4 Insert the water module’s threaded cylinder through the pit lid hole from the inside the lid.
5 Twist the cap until it locks onto the cylinder. This will attach the water module to the pit lid.
6 Tighten the spacer nut to secure the module to the pit lid.
If you are using a composite pit lid that has a shelf, slide the water module onto the shelf. Otherwise, use the same procedure for
attaching the module to the pit lid.
ELECTRICAL CONNECTIONS
The module has either an in-line connector or a length of cable with unterminated wires.
The in-line connector mates to a similar in-line connector from the water meter register/encoder assembly. To install:
1 Align the arrows on both connectors and press firmly to fully mate the connectors.
2 Check to make sure the connectors are fully mated (the two ends of the connectors are flush).
3 If they are not fully connected, press together again until they are fully connected.
The connector system is an air & water tight system, and the connectors may need to be pressed together multiple times to
remove the air pockets from the connectors. Do not disconnect the two connectors in between the multiple times you press
them fully together.
Modules with unterminated wires are often terminated & sealed by the water meter vendor. If the wires are not pre-terminated
and sealed: splice the wires from the water pit module to the wires from the register/encoder using weatherproof gel caps (for
example, 3M style 314 IDC). Follow the manufacturer’s directions for wire preparation when using gel caps.For proper operation
of the module, connect the wires as described in “Connection instructions” on page 1.
