control wire to the remaining wire of each valve. All wire splice
connections should be done using waterproof connectors.
3. Route valve wires through the conduit and attach conduit to one of
the openings on the bottom of the cabinet.
4. Strip ½" (13 mm) of insulation from ends of all wires. Secure valve
common wire to “COM” (Common) terminal. Attach all individual
valve control wires to appropriate station terminals.
