1.3.f 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.
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.
l
The adjustment procedure must be completed with the unit in heating mode .
PLEASE NOTE -
l
The installation of temperature ports are required for all commercial applications.
l
The installation of temperature ports are strongly recommended for residential installations.
n
See "Temperature Port Kit (# STK0096)" on page 29.
Temperature Port
(Shown with Probe)
1. Adjust thermostat to its lowest setting with 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 water filtration pump is operating properly with adequate flow and no short
cycling.
9. Wait for water temperatures to stabilize (approximately 5 minutes).
10. Adjust valves in the following order using the temperature chart provided:
a. Adjust the valve that controls water exiting the heat pump. Match the temperature measured with a
temperature probe to the chart.
b. Wait for water temperatures to stabilize. Then check temperature again. Re-adjust the valve as needed.
11. Mark valves at these positions for future reference.
