Caution
Your Hydro-Hot heating system operates off the coach’s sole diesel tank! Keep in
mind that the Hydro-Hot fuel tube is located higher up in the diesel tank than the
coach’s engine fuel in order to prevent complete depletion of the diesel fuel tank.
Be sure an adequate amount of fuel is in the fuel tank before dry camping.
The surge tank (Figure 3-3), located in the basement, should be routinely inspected to make sure the antifreeze
fill line stays in the acceptable zone. If the antifreeze becomes low, you must add the recommended antifreeze stated
in the Hydro-Hot’s owner’s manual. If antifreeze is totally depleted from the surge
tank, a switch will be released inside the main Hydo-Hot tank disabling the system
from operating. Antifreeze will then have to be added to the tank to reactivate the
switch and allow the system to operate.
If batteries accidentally become discharged and the Hydro-Hot system is activated,
the system will automatically shut down before batteries are totally discharged. Once
power is restored to batteries, the system must be reset
by depressing the reset button on the black panel of the
surge tank (Figure 3-3).
For detailed instructions on operating the Hydro-Hot Heating system, refer to the specific
owner’s manual found in the Owner’s Information Package.
