Switch Panel
3.20 Installing and Wiring the Switch Panel
The chosen location for the Switch Panel should allow for easy operator access. Also,
because the “Diesel” switch incorporates a fault light, which indicates a Diesel-Burner
malfunction, the Switch Panel should be easily visible to the operator.
1. Cut out an opening for the Switch Panel Plate; reference Figure 22.
AHE-100-04S: 3.75 in. W x 1.50 in. H
AHE-130-04X: 5.25 in. W x 1.50 in. H
2. Run eight 16 Gauge wires from the Switch Panel to the Electronic Controller.
NOTE:
Be sure to use the wire colors illustrated in Appendix A. This will ensure
installation consistency, differentiate between the separate switches and assist
Service Personnel with troubleshooting.
3. Strip and crimp insulated female terminals onto each wire at the Switch Panel
location. Also, be sure to prepare the necessary Jumper Wires.
4. Connect all switch wires as illustrated in Figure 23A and 23B for the AHE-100-04S
Model and Figure 24A and 24B for the AHE-130-04X Model. Reference Appendix A
for additional wiring information.
5. Insert all switch wires into the appropriate terminal/switch panel connection on the
Electronic Controller; reference Appendix A.
6. Permanently mount the Switch Panel in place.
7. Be sure to move all three switches to their
OFF
position by pressing them in a
downward motion.
3.21 Diesel-Burner’s Fuel System Overview
The Diesel-Burner is the Aqua-Hot’s primary heat source; therefore, care should be taken
when installing the fuel system.
A. The diesel fuel supply should be drawn directly from the Vehicle’s main Fuel Tank or
from a separate auxiliary Fuel Tank, if applicable. The Fuel Tank should be
equipped with a dedicated fuel pick-up (”Supply” port and “Return” port); reference
Figure 26.
NOTES:
1.
If an auxiliary Fuel Tank is required, be sure to consult the ANSI/NFPA 1192
Handbook concerning Diesel Fuel System specifications.
2.
These particular Aqua-Hot Hydronic Heating System models utilized two
unique Fuel Filters; therefore, please reference Figures 28A and 28B in
order to determine the Fuel Filter utilized in the particular model being
installed.
B. Fuel head pressure should not exceed 2 feet; reference Figure 25.
C. Use 1/4 inch I.D. (Inside Diameter) Fuel Lines.
D. The combined length of the supply and return Fuel Lines should not exceed 66 feet
in total length; reference Figure 25.
