The discharge location can be adjusted to 9:00, 12:00 (factory default), or 3:00 positions to suit your plumbing configuration.
4.4 Electrical Wiring
Connect the pump to a dedicated 220-240V/60Hz electrical circuit. Refer to the included wiring instructions and consult a qualified electrician to ensure correct and safe electrical connections. The pump operates at 4.4A on low speed and 12A on high speed.
5. Operating Instructions
Once properly installed and wired, the pump is ready for operation.
5.1 Initial Start-Up
Before starting the pump for the first time, ensure the spa is filled with water and all valves are open to allow water to flow freely to and from the pump. This will prime the pump and prevent dry running.
5.2 Speed Selection
This is a 2-speed pump. The speed selection is typically controlled by your spa's control system. Refer to your spa's main control panel manual for instructions on switching between low and high speeds.
- Low Speed: Ideal for filtration cycles and maintaining water temperature with reduced energy consumption. Input power: 0.75HP.
- High Speed: Used for jet operation, heating, and rapid water circulation. Input power: 4.0HP.
The pump provides a minimum flow of 90 GPM and a maximum flow of 202 GPM, depending on the selected speed and plumbing resistance.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your LINGXIAO SPA Pump.
- Regular Inspection: Periodically check the pump for any signs of leaks, unusual noises, or excessive vibration.
- Cleanliness: Keep the area around the pump clean and free of debris to ensure proper ventilation.
- Winterization: In colder climates, follow proper winterization procedures for your spa and pump to prevent freezing damage. This typically involves draining the pump and plumbing lines.
- Impeller Check: If flow rate decreases, inspect the impeller for any obstructions. Always disconnect power before accessing the impeller.
