3.1 Adjusting Water Flow Using ΔT (Delta-T)
The Delta-T is the temperature difference between the water temperatures entering and leaving the heat pump.
The equipment can be fine-tuned for maximum performance by balancing water flow rates to maintain an
ideal ∆T.
The adjustment procedure must be completed with the unit in heating mode.
l
Installed temperature ports are required to perform the following procedures.
l
These ports are typically located on the pool in and pool out water lines approximately six inches away from the
heat pump.
PLEASE NOTE -
l
The installation of temperature ports is required for all commercial applications.
l
The installation of temperature ports is strongly recommended for residential installations.
n
See " Temperature Port Kit (# STK0096) " on page 45.

(Shown with Probe)
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.
l
After a four-minute delay, the heat pump's compressor will start.
8. With the heat pump running, confirm the filtration pump is operating properly with adequate flow and no short
cycling.
9. Wait for water temperatures to stabilize (approximately 5 minutes).
