Question 1

How to make the phase, neutral, and ground connections in the Hayward RS II VSTD pump housing?

Accepted Answer

To correctly make the electrical connections (phase, neutral, and ground) in the Hayward RS II VSTD pump housing, it is important to follow the instructions below:

1. Locate the wiring diagram

A precise diagram of the connections can be found under the cover of the motor connection box. This diagram clearly indicates where to connect the phase, neutral, and ground.

2. Recommended wiring

Use a 3G1.5 mm² type H07RN-F cable with three wires: phase, neutral, and ground.
The ground wire (green/yellow) must be connected to the motor's ground screw (marked in green).
The phase and neutral wires must be connected to the corresponding terminals according to the markings under the terminals of the box.

3. Safety and precautions

It is imperative that all electrical connections be made by a qualified professional to ensure the safety and proper functioning of the pump.

In summary, always refer to the diagram under the cover of the box to identify the terminals, use an appropriate cable with phase, neutral, and ground, and consult a qualified electrician to make the connection.

Question 2

What should I do if the screen of the HAYWARD RS II VSTD pump is flashing without displaying anything?

Accepted Answer

If the screen of your HAYWARD RS II VSTD pump is flashing without displaying any information, it may indicate a technical issue or malfunction. Here are some steps to follow to try to resolve this problem:

1. Check the power supply

Ensure that the pump is properly plugged in and that the power supply is stable.
Check that the circuit breaker or fuse associated with the pump has not tripped.

2. Reset the pump

Turn off the power to the pump for about 30 seconds, then turn it back on to see if the screen resets.

3. Check internal connections

If you are comfortable with electrical work, check that the internal cables and screen connectors are securely attached and show no signs of damage.
If not, contact a professional.

4. Contact customer service

If after these checks the screen continues to flash without displaying any information, it is likely that the electronic board or the screen itself is defective. It is recommended to contact HAYWARD customer service or a specialized technician for a more in-depth diagnosis and repair.

Question 3

How to check and maintain the sand level in the HAYWARD S360SLETL water pump filter?

Accepted Answer

The sand level in the HAYWARD S360SLETL water pump filter is essential for ensuring effective filtration and the proper functioning of the device. Here’s how to check and maintain this level:

1. Checking the sand level

Open the filter: Carefully remove the filter cover to access the sand bed.
Observation: The sand should be evenly distributed and completely cover the filtering surface.
Measurement: The recommended level is generally about 15-20 cm below the top edge of the filter, allowing for good water circulation.

2. Maintaining and adjusting the sand level

Add sand: If the level is too low, it is necessary to top up with specific filter sand, following the manufacturer's recommendations.
Replacement: It is advisable to replace all the sand every 3 to 5 years depending on usage and water quality.
Regular checks: Perform periodic checks to detect any abnormal drop in level or signs of wear.

3. Additional tips

Avoid using unsuitable sand, which could damage the system.
In case of doubt or persistent issues, it is important to consult a qualified professional.

By following these steps, you will ensure optimal filtration and extend the lifespan of your HAYWARD S360SLETL pump.

Question 4

How to remove the cover of the HAYWARD EnergyLine Pro Fi Heat pump?

Accepted Answer

To access the internal components of the HAYWARD EnergyLine Pro Fi Heat pump, including the evaporator and maintenance elements, please follow this procedure that complies with the manufacturer's instructions:

Step 1: Electrical Safety
Before any operation, disconnect the power supply to the heat pump. This is imperative to avoid any risk of electrocution. You can turn it off via the control panel or directly at the circuit breaker.

Step 2: Access to the electrical hatch
Locate the electrical access hatch (reference HWX320922029) usually located at the back or on the side of the unit. Unscrew the screws holding it in place using an appropriate screwdriver and carefully remove this hatch.

Step 3: Removal of removable panels
The HAYWARD EnergyLine Pro Fi Heat pump is equipped with a right panel (HWX80700455) and a right decorative panel (HWX80900089) that can be removed. Unscrew the fasteners holding them in place (usually 4 to 6 screws depending on the panel) and gently lift them off.

Step 4: Access to the evaporator
Once the panels are removed, you can access the evaporator (cooling fins). If you need to clean it during annual maintenance, use a soft brush, compressed air, or water. Never use a pressure washer as it may damage the delicate fins.

Important: Maintenance operations and access to internal components should only be performed by qualified and authorized personnel. If you are not comfortable with these manipulations, contact an authorized HAYWARD technician or your installer. After each intervention, check the tightness of all hydraulic and electrical connections before putting the pump back into service.

Question 5

How do I disable the internal programming of the Hayward Max Flo XL VS pump so that it only operates with the pool clock?

Accepted Answer

To disable the internal programming and clock of the Hayward Max Flo XL VS pump so that it only operates according to the external pool clock, follow these steps:

Steps to disable internal programming

Access the control panel of the pump, usually located on the front of the unit.
Use the navigation buttons to scroll through the menu until you find the options related to programming or clock.
Disable the internal programming by selecting the corresponding option, often labeled "Programming off" or "Manual mode".
Confirm the changes by validating or saving the settings as indicated on the screen.
Connect the pump to the pool clock, if not already done, so that the pump operates according to the schedules set by this external clock.

Additional tips

Ensure that the pump is in manual mode or out of internal programming to avoid any schedule conflicts.
Check the electrical connections between the pump and the pool clock to ensure correct synchronization.

By following these steps, your Hayward Max Flo XL VS pump will operate only according to the pool clock, without using its own internal programming.

Question 6

How to prime the pump of the HAYWARD Powerline sand filtration kit in filtration mode?

Accepted Answer

To prime the pump of your HAYWARD Powerline sand filtration kit in filtration mode, follow these simple steps:

Steps to Prime the Pump

Check the pool water level: Make sure the water level is high enough to cover the skimmers. A level that is too low prevents the pump from priming correctly.
Turn off the pump: Before any handling, cut the power supply to the pump to ensure your safety.
Open the air purge cap: Locate the air purge cap on the filter and open it slightly to let trapped air escape.
Fill the pre-filter with water: If your pump has a pre-filter, open its lid and fill it with water until it is full. This facilitates priming by preventing the pump from sucking in air.
Close the purge cap: As soon as water starts to come out of the purge cap, close it quickly to prevent air from entering.
Restart the pump: Turn the pump back on and observe the pressure gauge to check that the pressure is stable and within the normal range.
Check for leaks: Inspect the seals and connections to ensure there are no air or water leaks that could prevent priming.

If the pump still does not prime after these steps, there may be a more complex technical issue requiring specific intervention.
