Rotoflow and Diversion Valve: The Rotoflow meter
measures product flow, and is supplied with a three-pin
plug-in connector. Plug it in to the Rotoflow cable and
seal the connection with the supplied heat shrink tubing.
The diversion valve cable has two wires with no polarity,
so they can be connected either way. Crimp the supplied
heat shrink butt connectors to the diversion valve leads
and heat them to seal. (See photo of diversion valve as-
sembly on page 13.)

Salinity Probe and Display Cables: The salinity probe cable is
hard-wired directly to the probe in the potting compound, and cannot be removed.
Secure the salinity cable to the wiring bundle with the rotoflow and diversion valve wire har-
ness, leaving enough loose cable for a service loop. Plug the salinity probe connector into the
jack marked “Salinity” on the MPC box.
Route the display cable from the display to the jack marked “display.”
Use only a Spectra-approved cable. The cable is not a standard LAN
cable or phone cord.
Take care not to damage the plugs on the ends of the cable when
routing. Slip the protective boots over the connectors to waterproof
them.
