Electrical Specifications 
Important – Qualified and licensed electricians must perform all electrical 
hookups. The following specifications must be followed in order to ensure proper 
performance and safety. 
 WARNING: Starting an incorrectly wired hot tub could cause severe damage 
to the mechanical equipment or even bodily harm. Have your 
licensed electrician verify GFCI (or RCD) wiring with the 
diagrams on pages 10-18 prior to starting the hot tub or call the 
technical support line at 727.573.9611. 
 Caution: Failure to abide by specifications listed may result in damage to the 
equipment and will void the warranty. 
All hot tubs must be wired with the appropriately sized wiring. Failure to do so will 
cause equipment damage and will not be covered under your warranty. 
All hot tubs must be over current protected with a built-in GFCI (or RCD for 
export models) in the service panel.
