*Special Instructions For All 120 VAC/240 VAC Convertible Models (J-315, J-325)
120 VAC Power Confi guration: Convertible models include a factory installed 15 foot GFCI cord
rated at 15A/120 VAC. To use the 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 such an outlet, it must be hard wired to a single pole 15A GFCI breaker. Refer to
pages 50-51 for your specifi c circuit board confi guration.
240 VAC Power Confi guration: Convertible models can be hard wired for 4-wire 120/240 VAC pow-
er. This confi guration powers the heater with 240 VAC while powering all other components with 120
VAC. An external 30 or 50A dual pole GFCI breaker is required. Refer to pages 50-51 for your specifi c
circuit board confi guration.
