240V Input Voltage
CONFIGURING SUV 120VAC/240VAC
Input Voltage (120VAC/240VAC Convertible SUV Packs)
This Power System is supplied to utilize a 240V power supply (2 hot wires, a neutral wire, and a ground wire). If
conversion to 120V is required, a jumper wire supplied with the system must be installed between J-16 and J35. Also, dip
switch #10 must be set to the “On” position. A 120V power supply (1 hot wire, 1 neutral wire, and a ground wire) can
then be hard wired to the power input terminal block labeled TB1. Attach the black wire to the terminal marked “Black,”
the white wire to the terminal marked “White,” and the green wire to the terminal marked “Ground.” See conversion
instructions on the wire schematic attached to the back of the power system enclosure cover.
When configured to operate at 120V, the heater is rated at 1.5kW and will heat only during Pump 1 low operation. When
configured to operate at 240V, the heater is rated at 4.0kW and will heat whenever heat is required.
Heat Recovery Pack Electrical
Important note:
If your hot tub has been built with a heat recovery pack from the
factory your hot tub will
also be equiped with a factory installed 120VAC GFCI power cord.
The free15 heat recovery pack is not convertible to 240VAC.

NOTE: All components are 120 volt- motors and ozone units.
Blowers are not provided. Do not covert on circuit board for
individual components.
When configuring the output voltages on the FreeFlow SUV System, remember to also consider the amperage of
each component. Be sure that the total amperage draw does not exceed the capability of the circuit supply and power to the system.
