Appliance description

The appliance is designed for indoor installation. The appliance
is equipped to heat water through a number of different heating
methods.
There are three ways that this unit can heat water:
- 3 kW electric resistance heating element
- Indirect heat via internal coil heat exchanger
- Indirect heat via auxiliary inlet/outlet ports
The entire heater and hot water system must be filled with water
and have adequate air ventilation. If used, please refer to the solar
collectors and the boilers installation instructions.
4.1

Heating the DHW tank

The first method of heating is by the 3 kW electric resistance heat-
ing element. This is the appliances most basic mode of operation.
An integral temperature sensor detects the thermal energy content
of the amount of heat in the DHW tank. The water in the DHW
tank is heated if the amount of heat is lower than that required to
achieve the set temperature.
The second method of heating is by the internal coil heat ex-
changer. This heat exchanger is designed to have a heat transfer
fluid circulate through it from an indirect heater. This indirect
heater can be a closed loop solar thermal system, boiler or other
traditional appliance that generates heat and transfers it through
a corrosion inhibited heat transfer fluid.
The third method of heating is by auxiliary ports located on the
side of the unit. These auxiliary ports offer direct access to the
domestic water in the tank. A flat plate heat exchanger should be
used to exchange heat between an indirect heater and the water
in the tank.

If either of the last two heating methods require a temperature
sensor, 2 ports are provided on the opposite side of the tank from
the auxiliary and heat exchanger connections.

Using the electric heating element

A 3 kW electric heating element comes standard with this product.
The element has a built-in temperature probe that detects the tank
water temperature.
The appliance's 3 kW electric resistance heating element is factory
preset at 125 °F (52 °C). The setpoint of the heating element can
be changed easily. A knob is located under the heating element
and can change the level of comfort to meet the needs of the user.
The heating element can be either unplugged during a period of
disuse or removed entirely.
For convenience, the heating element can be removed from the
tank without draining it.

available neutral cleaning agent. This should be done on a regular
basis.
WARNING
Never spray the appliance with water.
Never spray water into the appliance.
WARNING Injury
