Installation
3.25 Connecting 12 Volt-DC Power to the Aqua-Hot
WARNINGS:
A. Do not
activate the Aqua-Hot’s Diesel-Burner until the antifreeze and
water heating solution has been added to the Aqua-Hot’s Heat 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 Heat Tank.
B. Do not
connect the 12 Volt-DC Power or the Ground Wires to the
Aqua-Hot if the Vehicle requires welding. Electrical welding will cause
serious damage
to the Diesel-Burner’s Controller and the Aqua-Hot’s
Electronic Controller.
NOTE:
All Electric Installations, Systems, and Equipment must comply with Article 551,
Part A and other Sections of NFPA 70, “National Electrical Code.”
1. Run two 10 Gauge wires, Red for (+) and Black for (-), from the Vehicle’s Batteries to
the Aqua-Hot’s Electronic Controller; reference Appendix A and Figure 31.
NOTES:
A.
If the combined length of the two 10 Gauge wires is in excess of 20 feet,
reference Appendix B for proper wire gauge sizing. Please note that under
full load conditions, the Aqua-Hot can draw as much as 15.33 Amps of VDC
current.
Because the Aqua-Hot is designed to shut down in the event
that the VDC Voltage Level drops too low to properly operate, it is
imperative that the proper wire gauge be determined and utilized.
B.
The maximum allowable
voltage drop,
for the 12 Volt-DC Aqua-Hot, is 0.75
Volts-DC. Please reference Appendix B to ensure proper wire gauge sizing
is utilized.
NOTE:
Be sure to use the wire colors illustrated in Appendix A. This will ensure
installation consistency, differentiate between the two Power Wires, and assist
Service Personnel with troubleshooting.
2. Attach the VDC Power wires onto the appropriate terminal/battery connection on the
Electronic Controller; reference Appendix A.
3. Connect both Power and Ground wires
directly
to the Vehicle’s batteries.
NOTE:
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 31.
NOTE: The Aqua-Hot’s Electronic Controller must be reset anytime VDC Power is
disconnected and then reconnected to the heater.
The Electronic Controller
can be reset either by depressing the “Low Voltage Reset” button located on the
Electronic Controller (use a thin, straight object to access the reset button
through the small hole in the faceplate) or by turning
OFF
the “Diesel” switch on
the Heater’s Interior Switch Panel for approximately 30 seconds, then turning
the switch back
ON
. Reference Figure 32 for the location of the “Low Voltage
Reset” button on the Electronic Controller.
