Step 3: Installing the electric service for the heat immersion cable

a If you are installing the WaterPro2 in an area that experiences freezing temperatures, you may wish to install an immersion
heater (part 832381).
b Arrange for your electrician to install the electric service around the same time you are installing the water supply lines.
c Install the electric service outside of the thermal earth tube on the horizontal side under one of the water reservoirs. Do
not install on either A or B side below as there is a risk that the electric service will not be located under the unit as the
diameter of the thermal earth tube almost spans the entire width of the unit.
Warning!
The electric service should only be installed by a qualified / certified electrician. The electric supply
must run outside of the thermal earth tube, be properly grounded, and be installed and maintained in accordance
with all applicable electric codes.

Step 4: Installing a thermal earth tube

a Install a thermal earth tube around the vertical water supply line. It must be at least 1 foot (305 mm) below the frost line.
Ensure that the vertical water supply line is centered within the thermal earth tube.
b If you are in a colder climate, we recommend an additional thermal earth tube be used to extend its length by at least
another foot (305 mm).

Step 5: Pouring the concrete slab

a Before you pour the concrete, check that you are using the correct measurements for your WaterPro2. See
tank hole alignment
b The thermal earth tube should be flush with the top of the concrete slab.
Do not pour concrete into the thermal earth tube or fill the space with dirt or any other material, as it will prevent
warm air below the frost line from circulating around the vertical water supply line, and will cause the water line to
freeze.
