Balboa VS510SZ Retro Fit Kit

This kit is a comprehensive control system upgrade that includes the main circuit board, a 4.0 kW flow-through heater, and the VL701 topside control panel. It is designed to replace older, outdated spa control systems with a modern, reliable interface.

The VS510SZ is highly versatile and supports up to two pumps plus a blower or a third pump. As long as your current equipment falls within these configuration limits, this system should be compatible.

The system features dual-voltage compatibility, meaning it can be configured for either 115V or 230V installations. This flexibility makes it suitable for a wide range of existing spa electrical configurations.

Yes, the VL701 topside control panel is included with the kit. It provides a user-friendly interface for managing your spa's temperature and settings, ensuring you have everything needed for the upgrade in one package.

While the kit is designed for straightforward installation, it involves high-voltage electrical work. Unless you are experienced with spa electrical systems, we strongly recommend hiring a licensed electrician or professional spa technician to ensure safety and proper operation.
