High:
The process of moving the
“High/Low”
switch to the
“High”
position, in conjunction with
the activation of the
“Electric”
switch, allows both the
120 VAC/1650 Watt
and the
240
VAC/4500 Watt Electric Heating Elements
to supply heat to the Aqua-Hot’s
Boiler Tank
.
The
120 VAC/1650 Watt
and
240 VAC/4500 Watt Electric Heating Elements
will heat the
Aqua-Hot System
to the maximum operating temperature (190°F (+/- 5 degrees)) in
approximately 0.5-1 hour.
AHE-130-04X Model

, thereby illuminating the indicator light on the
switch; reference Figure 4.
Low:
The process of moving the
“High/Low”
switch to the
“Low”
position, in conjunction with
the activation of the
“Electric”
switch, allows one
120 VAC/2000 Watt Electric Heating
Element
to supply heat to the Aqua-Hot’s
Boiler Tank
. The
120 VAC/2000 Watt Electric
Heating Element
will heat the
Aqua-Hot System
to the maximum operating temperature
(190°F (+/- 5 degrees)) in approximately 1-2 hours.
High:
The process of moving the
“High/Low”
switch to the
“High”
position, in conjunction with
the activation of the
“Electric”
switch, allows both
120 VAC/2000 Watt Electric Heating
Elements
to supply heat to the Aqua-Hot’s
Boiler Tank
. These
120 VAC/2000 Watt
Electric Heating Elements
will heat the
Aqua-Hot System
to the maximum operating
temperature (190°F (+/- 5 degrees)) in approximately 0.5-1 hour.

Engine Preheat Switch
Function:
The
“Engine Preheat”
switch activates the Aqua-Hot’s
Engine Preheat
Circulation Pump
, thereby illuminating the indicator light on the switch; reference Figure
4. This procedure allows the
Engine Preheat Circulation Pump
to circulate the engine’s
coolant through a separate double-wall copper coil in the Aqua-Hot’s
Boiler Tank
, result-
ing in a warm engine for easy start-ups in cool temperatures. Please note that this
feature will be effective only if the
“Engine Preheat”
switch is
ON
in conjunction with
either the
“Diesel”
and/or the
“Electric”
switch.
