1.
2.
3.
Leave the transformer connector J4 plugged into the circuit board.
Set your voltmeter to the highest VAC range.
Place the voltmeter probes directly into the backside (wire side) of the J4 connector and test as
follows:
US/Canada 60Hz
J-315, J-325 (120 VAC or 240 VAC Powered*)
Connector J4 Voltage
Black to White 120 VAC*
Yellow to Yellow 12-14 VAC
US/Canada 60Hz
J-335, J-345 (240 VAC Powered)
Connector J4 Voltage
Black to Red 240 VAC
Yellow to Yellow 12-14 VAC
*Special Instructions For All 120 VAC/240 VAC Convertible Models (J-315, J-325)
120 VAC Power Con 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 speci c circuit board con guration.
240 VAC Power Con guration: Convertible models can be hard wired for 4-wire 120/240 VAC pow-
er. This con 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 speci c
circuit board con guration.
