DO NOT
activate the diesel-burner until the antifreeze and
water heating solution has been added to the boiler tank and the
heating system has been completely bled of air. Operating the
Aqua-Hot without the antifreeze and water heating solution will
cause
serious damage
to the Aqua-Hot’s boiler tank.
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 and the Aqua-
Hot’s electronic controller.
NOTE:
Reference Appendix B for proper wire-gauge sizing.
Please note that under full-load conditions, the Aqua-
Hot can draw as much as 22 Amps of DC 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.
Be sure to protect against accidental shorting (i.e.,
chassis shorting) by incorporating a 25-Amp rated in-
line fuse into the power wire at the battery location.
Reference Figure 46.
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 wiring harness connectors to the electronic con-
troller. Reference Figures 44 and 45 and Appendix A.
2. Tighten the screw-type fasteners on the terminal strips
to secure them to the electronic controller. Reference
Appendix C.
Wiring Harness Connectors
Connect corresponding 9 and 16 pin
connectors from wiring harness.
