1. Adjust the thermostat to its lowest setting with the unit in heating mode.
2. Deactivate the water filtration pump.
3. Confirm that the filters leading to the heat pump are clean.
4. Adjust the valves controlling water headed towards the heat pump to the half-open position.
5. Adjust the valves controlling water leading away from the heat pump to a fully open position.
6. Activate the pool water filtration pump.
7. Slowly raise the thermostat temperature until the heat pump activates.
The source-water filtration pump will cycle on first.

8. With the heat pump running, confirm the source-side water filtration pump is operating properly with adequate
flow and no short cycling.
9. Wait for water temperatures to stabilize (approximately 5 minutes).
10. Open the temperatures differences screen in the Geothermal Menus.
11. Adjust valves in the following order using the temperature chart provided.
a. Adjust the source-side valve on the heat pump outlet until the correct temperature differential is achieved.
b. Adjust the pool-side valve that controls water exiting the heat pump until the correct temperature differential is
achieved.
c. Wait for water temperatures to stabilize. Then check the source-side temperature again. Re-adjust the valve as
needed.
12. Mark valves at these positions for future reference.
