Preparing for Your New Portable Spa

 

120 Volt Electrical Installation

240 Volt Electrical Installation

Always follow applicable local, state and federal codes and guidelines.

Use only a dedicated electrical line with a 20 amp breaker.

Cord-and-plug connections may not use a cord longer than 15 feet (4.6 m) and must be plugged into a dedicated 20 amp GFCI connection (NEC 680.42(A)(2)). Do not use extension cords!

Always use a weatherproof-covered receptacle.

Receptacle shall be located not less than 5 feet (1.5 m) from and not exceeding 10 feet (3.0 m) from the inside wall of the spa. (NEC 680.43(A))

Do not bury the power cord. If your cord becomes damaged, replace it before next usage.

All 120V spas must have a GFCI. This can be either a 20 amp GFCI receptacle or a 20 amp GFCI cord and plug kit as shown (CKIT110 - P/N ELE09700086).

Test the GFCI plug prior to first use and periodically when the spa is powered. To test the GFCI plug version, follow these instructions. (Spa should already be plugged in and operational.)

1.Press the TEST button on the GFCI. The GFCI will trip and the spa will stop operating.

2.Press the RESET button on the GFCI. The GFCI will reset and the spa will turn back on.

The spa is now safe to use.

If the GFCI trips while the spa is in use, press the RESET button. If the GFCI does not reset, unplug the spa and call your local Cal Spas dealer for service. DO NOT USE THE SPA!

All 240V spas must be permanently connected (hardwired) to the power supply. These instructions describe the only acceptable electrical wiring procedure. Spas wired in any other way will void your warranty and may result in serious injury.

This is the only acceptable electrical wiring procedure. Spas wired in any other way will void your warranty. See the wiring diagram on page 7.

When installed in the United States, the electrical wiring of this spa must meet the requirements of National Electric Code, ANSI/NFPA 70-2008 and any applicable local, state, and federal codes. The electrical circuit must be installed by an electrical contractor and approved by a local building / electrical inspector.

GFCI and Wiring Requirements

The power supplied to the spa must be on a dedicated GFCI protected circuit as required by ANSI/NFPA 70 with no other appliances or lights sharing the power.

Use copper wire with THHN insulation. Do not use aluminum wire.

Use the table on the next page to determine your GFCI and wiring requirements.

When NEC requires the use of wires larger than #6 AWG, install a junction box near the spa and use #6 AWG wire between the junction box and the spa.

Wire runs over 85 feet must increase wire gauge to the next lower number. For example: A normal 50 amp GFCI with four #8 AWG Copper wires run over 85 feet would require you to go to four #6 AWG copper wires.

Read and follow the heater manufacturer’s safety and installation instructions prior to installation and operation. Incorrect installation may damage the heater and void its warranty.

Testing the GFCI Breaker

Test the GFCI breaker prior to first use and periodically when the spa is powered. To test the GFCI breaker follow these instructions (spa should be operating):

1.Press the TEST button on the GFCI. The GFCI will trip and the spa will shut off.

2.Reset the GFCI breaker by switching the breaker to the full OFF position, wait a moment, then turn the breaker back on. The spa should have power again.

GFCI specifications

Cal Spas GFCI (Ground Fault Circuit Interrupter) is an essential safety feature incorporated in Cal Spas hot tubs and spas, designed to protect users from electrical shocks and enhance overall safety during relaxation. This advanced technology monitors the electrical current flowing through the spa's components, providing peace of mind for families and individuals enjoying their hydrotherapy experience.

One of the main features of the Cal Spas GFCI is its quick response time. The GFCI continuously measures the current balance between the hot and neutral wires. If it detects an imbalance, potentially caused by faulty wiring or a short circuit, it immediately trips the circuit, cutting off power to the unit within a fraction of a second. This rapid response significantly minimizes the risk of electrical accidents, making it a vital component for any outdoor or indoor spa setup.

Another key characteristic of the Cal Spas GFCI is its user-friendly design. The GFCI outlet is often equipped with a reset button, which allows users to quickly restore power once the issue has been addressed. This feature eliminates the need for complicated maintenance procedures, ensuring that users can enjoy their spa without frequent interruptions.

Incorporating state-of-the-art technology, Cal Spas GFCI is designed to withstand the rigors of outdoor environments. The durable exterior of the GFCI unit protects it from exposure to moisture, debris, and other potential hazards, leading to increased longevity and reliability. Moreover, the GFCI meets the highest safety standards and regulations, providing confidence to consumers that they are investing in a safe product.

Another highlight of the Cal Spas GFCI is its compatibility with a variety of hot tub configurations. This flexibility allows it to work seamlessly with different Cal Spas models, delivering consistent safety features across the entire range. Additionally, installation is straightforward, with many users opting for professional installation to ensure it is set up correctly.

In summary, Cal Spas GFCI enhances the safety of hot tub and spa experiences through its quick trip response, durable design, user-friendly functionalities, and compatibility with various models. By integrating this technology, Cal Spas demonstrates its commitment to providing a safe and enjoyable environment for relaxation and rejuvenation.
