Overview
The Aqua-Hot is equipped with a Tempering Valve, which regulates the temperature of
the hot water; reference Figure 19.
1. Connect a domestic water Plumbing Line from the Domestic Water Demand
Pump/Water Manifold to the Cold Water Inlet port on the Aqua-Hot; reference
Figures 19 and 20.
NOTE: Please note that it may be necessary to utilize an Accumulator Tank within the
Domestic Water System; reference Figure 20. Although the Aqua-Hot is
equipped with a Pressure-Relief Valve, the utilization of an Accumulator Tank will
help prevent excessive “weeping” of the aforementioned valve, if applicable.
Manufacturers of Pressure-Relief Valves indicate that excessive weeping of
these valves will cause the “seat” in the valve to deteriorate, and, in turn, the
valve will fail prematurely. For additional information regarding Accumulator
Tanks, please be sure to reference the Recreational Vehicle Industry
Association’s (RVIA) technical publication titled “Recreational Vehicle Plumbing
Systems.” To obtain a copy of this particular publication, please contact RVIA at
(703) 620-6003 or visit them online at www.rvia.org.
2. Connect a domestic water Plumbing Line from the Aqua-Hot’s Hot Water Outlet
port to the hot water system’s Distribution Lines/Water Manifold; reference Figures
19 and 20.
3.14 Electronic Controller Overview
The Aqua-Hot utilizes an Electronic Controller (E.C.) to monitor specific heater activities,
supply electrical power to specific internal and external components, and control the
overall operation of the heater. The following are important installation details regarding
the Electronic Controller. Please read this section thoroughly for specific details.
NOTE: Please reference Appendix A for specific wiring information pertaining to the
precise model of Aqua-Hot being installed.
A. All Electronic Controller Fan Power connections (and two switch connections)
possess a “(+)” or a “(-)” symbol, which indicates that they are Polarity Sensitive.
Therefore, be sure to use care when wiring these particular components to the
Electronic Controller.
