Initial Start-Up - Hayward Powerline 15-81500 Manual De Instalación E Instrucciones

3. INSTALLATION AND CONNECTION
3.5 Swimming pool heat pumps: electrical connection
NOTE: The unit heat exchanger is electrically insulated from the rest of the unit, this simply prevents the flow of
electricity to or from the pool water. Grounding the unit is still required to protect you against short circuits inside
the unit.
NOTE: ensure that the available electrical Power supply and the network frequency are matched to the required
operating current, taking account of the appliance's specific location and the current required to supply any
other appliances connected to the same circuit.
1) See the wiring diagram chapter 6.3;
2) Ensure that the unit is supplied with the specified voltage. The terminal block is located on the right side of
the unit. There are three connections for the Power supply and two connections for the filtering pump control
(Enslavement). The Power supply line must be properly matched with a motor supply type fuse or a main
circuit breaker to protect the circuit against voltage surges (refer to the nameplate for the voltage);
3) Always shut down the main Power supply before opening the electrical control box.

3.6 Initial Start-up

Start-up Procedure. After installation is completed, you should follow these steps:
1) Switch on the filtering pump;
2) Check that all the water valves are open and that the water flows into the unit before switching on heating or
cooling;
3) Ensure that the unit is connected correctly to the main Power supply (refer to the wiring diagram or chapter 2);
4) Rotate the fan by hand to ensure that it turns freely and that the turbine is properly tightened with the motor
shaft;
5) Check that the condensate drainage hose is properly attached and free of any blockages;
6) Switch on the power supply to the unit, then press the On/Off key on the wire controller;
7) Ensure that no ALARM code is displayed when the unit is ON (see Trouble shooting guide);
8) Set the water flow using the by-pass valve (see chapter 3.1) as described for each different model (see the
control panel or chapter 2) to obtain a 2°C difference in water temperature.;
9) After running a few minutes make sure the air leaving the unit is cooler (between 5-10°C);
10) With the unit operating turn the filter pump off. The unit should also turn off automatically;
11) Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is reached. When
the set water-inlet temperature is reached, the unit shuts off. The unit will now automatically restart (as long
as your pool pump is running) when the pool temperature drops more than 2°C below set temperature.
Water Flow Switch - the unit is equipped with a flow switch that turns it on when the pool pump is running
and shuts it off when the pump shuts off. This switch is the same type used in all gas pool heaters and is
factory adjusted for normal pool installations. If the pool water level is more than a few feet above or below the
thermostat knob of the unit, your dealer may need to adjust it at initial start-up.
Time Delay - the unit is equipped with a 3 minute built-in solid state restart delay to protect control circuit
components and to eliminate restart cycling and contactor chatter. This time delay will automatically restart the
unit approximately 3 minutes after each control circuit interruption. Even a brief power interruption will activate
the 3 minute restart delay and prevent the unit from starting until the 3 minute countdown is completed. Power
interruptions during the delay period will have no effect on the 3 minute countdown.
