CAMPING
The Emergency Cutoff lamp will indicate when there is a low liquid level in the heat tank,
a strong impact to the unit, or when power has been disconnected from the system for
an extended period of time. Low voltage supply may also trip the Emergency Cutoff
Switch, causing the Hydro-Hot system to cease operation because the RV house bat-
teries have reached a state of charge insufficient to operate various sub-systems that
comprise the Hydro-Hot system.
In the event a red light illuminates in the Emergency Cutoff lamp, the electronic control-
ler must be manually reset. Using a small screwdriver, or one end of a paperclip, reset
the Low Voltage/Reset button located on the electronic controller.
Heating
The are three thermostats that are used to control heat to areas of the motorhome.
The bath/bedroom area thermostat is located under the medicine cabinet.
For the basement area, a thermostat knob is located next to the Hydro-Hot Control
Panel in the basement compartment.
The living area heat is controlled by the air conditioner Comfort Control Center
mounted on the galley wall. Push the zone button to the furnace mode and adjust the
thermostat.
When there is a call for heat, the system will activate the circulation pumps only after
confirming there is no demand for domestic hot water. While interior heat is supplied
through the Hydro-Hot system, the fan speed selector switches (certain models) will
have power applied and produce an audible sound when engaged.
Expansion Tank
The expansion tank, a clear plastic bottle, resembling a small version of the engine
coolant reservoir, is located in a curbside basement compartment. When the Hydro-
Hot system is at operating temperature, visually inspect the coolant level of the tank on
a monthly basis, and refill as needed. Refer to the manufacturer’s manual for specific
instructions on system operations, winterization procedures and maintenance require-
ments.
The coolant reservoir should be inspected monthly, when the diesel burner has shut
off, to confirm that coolant within the hydronic heating system is at the full hot level.
At installation, the Hydro Hot systems rely on this coolant that contains a 50/50 mixture
of distilled water and non-toxic Propylene Glycol Based Boiler Antifreeze that is pink
in color. Add additional antifreeze as needed. Do not mix antifreeze types. This boiler-
type antifreeze is available through Vehicle Systems, Inc., and should be combined
with 50% distilled water prior to adding. Using other than the recommended type
antifreeze within the hydronic heating system can cause scaling and possible compo-
nent failure. Add antifreeze when the system is at operating temperature. Refilling the
coolant reservoir when the system is cold may cause the fluid to overflow when the
system heats up.
Standard RV and Marine antifreeze formulated specifically for winterizing application
only, should not be used in the RV heater hydronic system. Because this type of an-
tifreeze does not contain rust inhibitors, it is not designed to transfer heat, which is
essential to the heating system function.
Auto coolant is designed to specifically protect automobiles against corrosion, freez-
ing temperatures and overheating. Auto coolants also provide excellent heat transfer
and thermal conductivity characteristics. Although these types of antifreeze products
are considered less toxic, they contain high levels of chemical rust inhibitors. These
potentially hazardous properties make this type of antifreeze unsuitable for the heater
