The BALBOA WATER GROUP g4310-02 is a BP100 Series spa control pack designed to manage the core electrical systems of a hot tub or portable spa. It ships with an M7 heater assembly included and supports a 4.0 kW stainless steel heater. The pack handles pump, blower, ozonator, and lighting circuits in a single integrated unit. Licensed pool and spa technicians install this control pack as a complete system solution for entry-level and mid-range spa builds or replacements.
The g4310-02 is suited for residential hot tubs and portable spas that require coordinated control of heating and hydrotherapy equipment. It accepts a two-speed pump operating at either 120 volts or 240 volts, or a single-speed pump or blower at 120 volts or 240 volts. The onboard outputs also support an ozonator and a spa light, making it a capable all-in-one pack for standard spa configurations.
Designed as an OEM-style replacement or new-installation control pack for residential portable spas requiring a single integrated heater and pump controller.
Installation should be performed by a licensed electrician or certified pool and spa technician in accordance with NEC Article 680 and local jurisdictional requirements. Disconnect and lock out all power to the spa before removing or installing the control pack. Verify that the supply voltage and circuit ampacity match the pack requirements before energizing. Do not bypass or modify onboard safety devices.
