Installation Manual for SB32-9PV and SB64-9PV
Close the main cold water supply valve to the existing water heater.
Install two copper tees and a ball valve #1 as shown in the diagram. Label this ball
valve: BALL VALVE #1.
Insulate all hot water pipes and the 5 feet of cold pipe leading to the solar storage
tank. All insulation should be Elastomeric Expanded Closed Cell with a minimum
thickness of 0.5”
Connect the main cold water supply to the cold inlet of the solar preheat tank.
Install a ball valve in this line. Label this valve: BALL VALVE #2.
Connect the hot outlet of the solar
storage tank to the cold water
supply of the existing water heater.
Install a ball valve in this line, and
label it: BALL VALVE #3.
Install two heat traps as shown in
the diagram to minimize heat loss
from the solar storage tank. Please
note that the domestic hot water
supply line must have a mixing
valve installed as shown in the
diagram.
Insulate all hot water pipes.
For normal solar operation, the valves should be opened or closed as shown
