Initial Start-Up - Hayward SUMHEAT HP5171DT3 Installation Instructions Manual

3. INSTALLATION AND CONNECTION (continued)

3.5 Initial start-up

Start-up procedure - After installation is complete, follow these steps:
1) Rotate the fans by hand to verify that they can turn freely by hand, and
that the turbine is correctly affixed to the motor shaft.
2) Ensure that the unit is connected correctly to the main power supply (see
the wiring diagram in the appendix).
3) Activate the filtration pump.
4) Verify that all water valves are open and that the water flows toward the
unit before switching on the heating or cooling mode.
5) Verify that the drainage hose is correctly affixed and that it causes no
obstructions.
6) Activate the unit power supply, then press the On/Off button
control panel.
7) Ensure that the alarm signal ( ) does not light up red.
If necessary see the troubleshooting guide (see § 6.4).
8) Set the water flow using the by-pass valve (see § 3.6 and 2.1), as
provided for by each model, to obtain an Entry/Exit temperature of 2°C.
9) After running for several minutes, verify that the air exiting the unit is cool
(between 5 and 10°).
10) With the unit operating, turn off the filter pump. The unit should
automatically turn off and display error code E03 (See § 6.4).
11) Allow the unit and the pool pump to run 24 hours per day until the
desired water temperature has been reached. When the set water inlet
temperature is reached, the unit will turn off. It will automatically restart (as
long as the pool pump is running) if the pool temperature is at least 0.5°C
below the set temperature.
Water flow switch - The unit is equipped with a flow switch that turns on the
heat pump when the pool filtration pump is running, and deactivates it when
the filtration pump is out of order. If the water is low, the E03 alarm code will
appear on the regulator (See § 6.4).
