Aqua-Hot First Operation
Activation Instructions
1. Make sure power supply to the Aqua-Hot is on.
2. Confi rm that the antifreeze and distilled water heating
solution is adequately fi lled.
3. Confi rm the system and heating loop has been properly
purged of any air.
4. Make sure to fl ush the domestic water system thoroughly
with clean water prior to use.
5. Reinstall the Aqua-Hot’s main access cover and the
fastener, which secures the front of the Aqua-Hot’s access
cover to the mounting tray.
6. Turn the diesel burner ON, either on the switch panel or the
coach control panel, for approximately 10 seconds ONLY,
then switch it to OFF.
7. After the purge cycle has ended, repeat once more.
8. Move the diesel burner switch to the ON position, and leave
it on in order to activate the diesel burner.
9. Move the Aqua-Hot’s electric element switch to the ON
position in order to supply 120V AC power to the electric
heating element.
10. Allow approximately 1-2 hours for the Aqua-Hot to reach
normal operating temperature (~185°F).
NOTE: Both the 12V DC diesel burner and the electric
heating element are thermostatically controlled. Either or
both will automatically maintain the temperature of the
boiler tank’s antifreeze and water heating solution.
The Aqua-Hot is now ready for normal operation and use.
NOTE: The main access cover must be installed prior to
operation. A safety switch (interlock switch) exists, which
will prevent the Aqua-Hot from operating whenever the main
access cover is not properly or securely installed.
NOTE: This procedure will purge the diesel burner’s fuel
system, by allowing the heater’s fuel pump to complete its
normal 30-150 second shutdown/purge cycle.
NOTE: It will take approximately 10 seconds before the
diesel burner will ignite and exhaust can be heard exiting
the heater. Allow approximately 10-20 minutes for the Aqua-
Hot to reach normal operating temperature (approximately
190°F).
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 boiler tank.
