*Special instructions for all 120 VAC/240 VAC convertible power models.
120 VAC Power Configuration: Convertible models include a factory installed 10 foot GFCI cord
rated at 15A/120 VAC. To use cord the hot tub must be installed within 10 feet of a dedicated,
grounded type electrical outlet. Do not use an extension cord of any type! If the hot tub is more than
10 feet from an outlet, it must be hard wired to a single pole 15 amp GFCI breaker. Refer to pages
43-46 for specific circuit board configurations.
240 VAC Power Configuration: Convertible models can be hard wired for 4-wire 120 VAC/240
VAC power. This configuration powers the heater with 240 VAC while powering both pumps and
ozone with 120 VAC. An external 30 or 40 amp dual pole GFCI breaker is required. Refer to pages
43-46 for specific circuit board configurations.
