General Information
Your Aqua-Hot 600 series unit will contain a Reporter
unit, which serves to replace the electronic controller in all
new units.
Should the Aqua-Hot Hydronic Heating System fail to
operate, complete the following steps:
1. Verify that the Aqua-Hot's access cover is securely in-
stalled. Reference page 7 (part #2). The Aqua-Hot Hy-
dronic Heating System will not operate if the access
cover is not fully installed.
2. Ensure that the vehicle's fuel tank contains a sufficient
level of fuel. The Aqua-Hot system will not operate if
the fuel level is at or below 1/4 tank.
3. Ensure that the Aqua-Hot's boiler tank has an ade-
quate supply of antifreeze and water heating solution
by checking the level at the Expansion Tank. If the level
is low, reference the Care & Maintenance section of
this guide for refilling instructions.
4. Check the Aqua-Hot Reporter faults screen and if any,
record all fault conditions which have occurred.
If the Aqua-Hot Heating System's failure to operate is
not resolved with the aforementioned checks, please con-
tact the Aqua-Hot Heating Systems Technical Support De-
partment at 1-800-685-4298 for additional assistance or
visit our web site at www.aquahot.com.
If the Aqua-Hot's diesel-burner switch "Indicator Light"
does not illuminate and the diesel-burner is not functioning,
locate the Reporter and check the following:
NOTE: An interlock switch prevents the Aqua-Hot from oper-
ating when the cover is not installed and properly in place.

Reporter Diagnosis
1. Check the Reporter fault screen for any fault conditions
associated with this unit (Figure 1.) Record these con-
ditions.
2. Check for loose wire connections on the Reporter by
removing the four bolts or screws securing the housing
to its mounting position. It may be necessary to check
with your coach manufacturer to determine the best
way to remove the Reporter.
3. Remove the Reporter and ensure that all connections
are secured, and that the wires are in good condition
Reference Figure 2.
4. Ensure the vehicle's fuel tank has a sufficient level of
fuel.
5. If the Aqua-Hot still fails to operate, please contact the
Aqua-Hot Heating Systems Technical Support Depart-
ment at 1-800-685-4298 or visit our web site at
www.aquahot.com.
