Wiring (continued)
Mount the main power terminals on a bulkhead adjacent to the feed pump module. Make
sure that this is a dry location well above bilge level and not subject to water spray.
Route the control cable through the boat to the MPC display location. Be careful not to dam-
age the connector. Plug this into the back of the control.
Route the Clark Pump harness to the Clark Pump/membrane module location and plug in the
RotoFlow meter. See photo page 15. Plug in the salinity sensor cable and install the plastic
boot over the connection. Locate the diversion valve wires and splice the remaining two
conductor cables with the supplied butt splices The diversion valve wires have
no polarity .
Heat-shrink connectors or heat shrink tubing is supplied so you can seal the connections af-
ter splicing.
Route the single two conductor cable to the fresh water flush module and splice the wires to
the solenoid wires. There is no polarity to the wires. Heat the splice for sealing.
Check the wire size chart to select the proper size power feed to the main power harness.
DC power feeds should be uninterruptible to insure proper operation of the auto store fea-
ture. Avoid house breaker panels that could be easily tripped.
Component Sizing:
•
12V- Use a 25Amp breaker and size the wiring for 20 Amperes.
•
24V– Use a 15 Amp breaker and size the wiring for 10 Amperes.
•
Provide circuit protection at the source! Inadequate wiring will cause a loss of
system performance. DC power should be uninterruptible.
Note: If the specified circuit breaker sizes are unavailable, use the next higher rating
but do not exceed the specification by more then 10%. All wiring to be done to
applicable ABYC, Marine UL or CE standards.
