Sunbank Installation Manual
13. Tube Installation
The last step is to install the tubes. You can also find video instructions on our Youtube page.
1.
Note tailstock comes apart. Unscrew the black plastic at the bottom of the bracket. Put the
dust ring around the top end of the evacuated tube
about 2 inches from the top. Use mild soap and
water to ease on the dust ring.
2.
Put the bottom of the evacuated tube through the
end of the unscrewed plastic tailstock and pull the
heat pipe out of the tube about six inches.
3.
Guide the condenser bulb of the heat pipe into the
tank socket until you hear it bottom out in the tank
(~4 inches). Rotate the tube if there is resistance.
4.
Slide the tube so that it fits up against the tank.
Maintaining upward pressure on the tube, screw the
cap of the tailstock on to hold the tube in place. It
should screw easily
—
be sure that you have the
threading lined up. You can twist the tube to help
twist the tail stock. Do not overtighten.
5.
Adjust the dust ring so that it fits snugly between the
tank and the tube.
6.
Repeat.
14. Controller
Sunbank offers a WiFi Smart Home Controller, as well as a hard wired controller option. Their primary
function is to control the backup heating element (if used) as a thermostat, but they do have several
other useful features. In order to use the backup heating element, you MUST use a thermostat
(controller). In addition to turning on and off the heating element based on temperature, they also
give you a digital readout of the temperature in the Sunbank. Knowing the temperature in the
Sunbank is important to understand that the system is functioning correctly. In addition to these
functions, it can also provide both overheat and freeze protection when coupled with a recirculation
valve and pump kit, both of which we sell on our website. For installation and programming
instructions, see our Youtube page. For more information see our controller, freeze protection and
overheat protection information pages:

15. Temperature Sensor
While you are putting teflon tape on the temperature sensor thermowell you will notice that it extends
6 inches or so up into the tank. When you are installing the actual temperature sensor wire it is
important that it goes all the way to the end of this well. This ensures an accurate reading.
