Domestic Hot Water System - Aqua-Hot 400 Series Use And Care Manual

Activating the Aqua-Hot Hot Water System

Domestic Hot Water System

General Information:
The Aqua-Hot system is known as an on-demand hot water
heating system because hot water is not stored within the
coach. Instead, when the burner and/or electric element is
ON and the Aqua-Hot is at operating temperature, the water is
automatically heated as it is being used. Therefore, simply open
a hot water faucet once system is up to operating temperature,
and a continuous supply of hot water will be present within a
few seconds.
To operate the Aqua-Hot hot water system, you will need to
locate the interior switch panel or coach control panel located
inside your coach. If you are unable to locate the interior panel,
contact your dealer to guide you in the location and operation
of all switch operations. Once you have located the interior
control panel, turn the burner to ON. This action will activate the
propane-burner. Allow 10-20 minutes for the Aqua-Hot system
to reach operating temperature. Please note that the propane-
burner is the primary heat source for heating the interior and
hot water.
To operate the electric heating element, turn the electric
ON. This action will activate the 120 Volt-AC electric heating
element. Allow 1-2 hours for the Aqua-Hot system to reach

operating temperature. Be sure to activate the burner switch
for maximum water capacity.
Some coaches may be equipped with touch-screen panels in
lieu of the Aqua-Hot three-switch panel. If you are unsure if your
coach is equipped with touch screen controls, please contact
your coach manufacturer.
Tempering Valve
The Tempering Valve for the Aqua-Hot mixes the heated
domestic water from the boiler tank with cold domestic water
at the present ratio to reduce the risk of scalding. This valve is
located in the back of the Aqua-Hot unit as shown in Figure 8.
The pink paint witness mark verifi es that the Aqua-Hot is set at
the correct factory setting and did not get tampered with during
shipping or installation.
Verify that the Tempering Valve is set at the proper temperature
by using a digital thermometer at one of the hot water faucets.
The water temperature should range between 115°F to 123°F.
If the correct temperature cannot be set, please contact Aqua-
Hot Heating Systems Technical Support Department at 574-AIR-
XCEL (574-247-9235) for additional assistance or visit our web
