Wiring Harness Connection; Connecting The 12 Volt-Dc Power - Aqua-Hot 600-D Installation Manual

NOTE: Reference Appendix B for proper wire-gauge sizing.
Please note that each "FAN" circuit on the electronic
controller can supply a maximum of 2.0 Amps of
direct current.
Because the Aqua-Hot is designed to shut down in
the event that the DC voltage level drops too low to
properly operate, it is imperative that the proper wire
gauge be determined and utilized.
All electric installations, systems, and equipment
shall comply with Article 551, Parts I and III through
VI of NFPA 70, as well as the regulation of authorities
having jurisdiction and CSA Standard B139.

Wiring Harness Connection:

1. Attach the wiring harness connectors to the electronic
controller. Reference Figure 43 and Appendix A.
section 9: Electronic Controller Wiring
Connect corresponding 9 and 16 pin
connectors from wiring harness.

2. Tighten the screw-type fasteners on the terminal strips
to secure them to the electronic controller. Reference
Appendix C.

Connecting the 12 Volt-DC Power:

DO NOT connect the 12 Volt-DC power to the Aqua-Hot if
the vehicle requires welding. Electrical welding will cause serious
damage to the diesel-burner controller.
NOTE: The Aqua-Hot is designed to shut down in the event
that the DC voltage level drops too low to properly
operate; therefore, it is imperative that the proper wire
gauge be determined and used.
Be sure to protect against accidental shorting (i.e., chas-
sis shorting) by incorporating a 30-Amp rated in-line
fuse into the power wire at the battery location. Refer-
ence Figure 45.
