ELECTRICAL REQUIREMENTS - 

DANGER – RISK OF ELECTRIC SHOCK 

Installations  that  do  not  comply  with  the  following  procedures  and  requirements  may  expose  users  to  electric  shock.  

Non-compliant installations will result in warranty nullification. 

This hot tub’s electrical wiring must comply with all applicable requirements of the federal, provincial/state and 
local building codes. The electrical circuit (outlet) must be installed by a certified electrical contractor and 
approved by a local electrical installation inspection authority. 

1. 

Any metal surface located within 1.5 m (5 feet) must be grounded to the hot tub. Use an 8 AWG (8.4 mm²) solid copper   

  wire and attach it to the grounding lug on the power pack, located in the equipment compartment.  

2. 

Power supply installation must include a suitably rated ground fault circuit interrupter (GFCI) as required by NEC Article   

  680-42. The circuit breaker must be dedicated and should not be shared with any other appliance. It must be labelled    

  and easily accessible to users. 

3. 

The electrical circuitry for the hot tub must include a suitably-rated switch or circuit breaker to open all ungrounded 

  supply conductors in compliance with Section 422-20 of the National Electric Code, ANSI/NFPA 70. The disconnecting    

  means must be readily accessible to the hot tub’s occupant but installed at least 1.5 m (5 feet) from the hot tub water.

4. 

Power supply must be hard wired into the power pack. DO NOT use extension or plug-type cords of any kind. The instal  

  lation of a shut-off box near the hot tub is also recommended. This box provides a quick and convenient method to shut  

  off power to the hot tub for emergencies and maintenance.  

5. 

Power supply wiring must be properly sized as per the NEC (National Electric Code). A grounding wire must be provided  

  that is as large as the largest current carrying conductor, but no less than 8 AWG (8.4mm²). Use copper wiring only. 

6. 

Open the front cover of the power pack, and follow the instructions and wiring diagram printed on the back of the  

  cover.  

7. 

All 120 VAC powered models must use the provided GFCI cord plugged directly into a dedicated grounded wall outlet. 

CIRCUIT BREAKER REQUIREMENTS 

A GFCI is included with your new spa-Ô. You should not use it in an outlet where another GFCI is already plugged. Two GFCIs 

in contact will render the spa-Ô inoperable. If you need to take out the GFCI included with the spa-Ô, make sure you use 

a 240 VAC 10 VAC 0 -15 amps capacity – 14-3 gauge wire. Do not use an existing breaker if its voltage and amperage is 

unknown.  

The spa-Ô must be connected to a dedicated GFCI circuit breaker that is not shared with any other equipment. Do not use 

extension or plug type cords of any kind.

The GFCI must be protected from water, snow and extreme temperatures.

HEATER CONVERSION 

For your spa’s specific instructions concerning 120 VAC to 240 VAC heater conversion see the back of your spa pack’s cover 

plate. Please note that your warranty will only be valid with proof of conversion by a certified licensed electrician.

When configuring the output voltages on the spa-Ô System, remember to also consider the amperage of each component. 

Be sure the total amperage draw does not exceed the capacity of the system’s circuitry and power supply.

Reminder: The spa equipment requires a dedicated 15 amp outlet. The use of an extension cord will void your warranty. 

Carefully read all of the safety requirements before plugging in the spa. Make sure that the electrical cord has been 

routed properly. Do not supply electrical power at this point.
