NOTE: Both the Diesel-Burner and the Electric Heating Element are thermostatically controlled. Either, or both, heating sources will automatically maintain the temperature of the Aqua-Hot's water and antifreeze solution between approximately 160-190 (+/- 5) degrees Fahrenheit. So to heat your motorhome / domestic hot water, simply choose the desired heat source(s) and leave the switch(s) (i.e. Diesel and/or Electric) ON. Comfort Control 2.
B. Turn OFF the Aqua-Hot's Engine Preheat switch whenever engine preheating is not desired. NOTE: The Aqua-Hot's Engine Preheating System acts as a supplemental heating source, in addition to the Diesel-Burner and the Electric Heating Element. While traveling, the engine's heated coolant will automatically pass through the Engine Preheat / Motoraide System, transferring heat into the Aqua-Hot's Boiler Tank.
DieselBurner Operational Flow-Chart 2.6 Diesel-Burner Operational Flow-Chart ~ Reference Figure 3 for all numbers indicated inside parenthesis. (e.g. #8). Operation sequence once the Aqua-Hot’s Diesel switch is turned ON. NOTE: The Diesel switch’s Indicator Light will illuminate (reference Figure 2), while the Heating Status and Diesel-Burner Status lights illuminate on the Electronic Controller, reference Figure 5.
Important Information 2.7 Precautions WARNINGS: • The Aqua-Hot's Exhaust is HOT! • DO NOT park in areas where dry conditions exist underneath the vehicle, as a fire may result (i.e. in a dry grassy field for example). • DO NOT operate the Aqua-Hot’s Diesel-Fired Burner inside an enclosed building. • The Heater should be switched OFF when refueling. CAUTION: DO NOT operate the Diesel-Burner and/or the Electric Heating Element without the water and antifreeze solution in the AquaHot’s Boiler Tank.
Filter, along with a thorough cleaning of the Combustion Chamber, if necessary (reference Figure 4). To ensure maximum Diesel-Burner performance, always use the recommended Fuel Nozzle (i.e. 0.35 GPH) and Fuel Filter (i.e. 10 Micron) when replacing these parts. Reference the Aqua-Hot “Parts Manual” for spare parts information.
C. Attach an adequate piece of hose onto the suction side of the domestic water demand pump. D. Place the opposite end of the hose into an adequate supply of FDA approved RV-Antifreeze. E. Open / close all interior and exterior water faucets, one at a time, until only pure RV-Antifreeze is present. Perform this procedure for both the hot and cold faucets. F. Remove the hose and reconnect the domestic water demand pump's suction line to the fresh water storage tank. G.
Electronic Controller 5.
Electronic Controller, continued The Aqua-Hot will automatically restart once the electrical overload (i.e. short) and/or high heat condition is corrected. Heating Zones Status Indicator Lights: These five indicator lights (separately) will illuminate GREEN whenever a Zone Thermostat, for each particular zone, is calling for heat. The GREEN indicator lights also indicate that VDC power is being supplied to the particular interior heating zone’s Heat Exchangers (i.e. fan motors).
