240V GFCI and Wiring Requirements
All VS-300 and VS500 control systems are set at the factory to run on the low power setting for low amperage
operation. This is the default setting. Spa owners can have their installer change this setting so the spa will run
on high power for 50 or 60 amp operation.
Warning: Never set a spa to run on high power without installing a properly rated GFCI .

VS-500 System High Power Configuration
The two and three pump VS-500 systems can run with
higher power than the VS-300 system. For the VS-500
system, DIP switch #6 is factory set in the ON position.
This causes the heater to shut off when any pump
is running in high speed. To operate the spa in high
power mode, ensure the following steps are performed
before starting your spa:
When installing the electrical system, use a 50 or
•
60 amp GFCI as appropriate. (See the table above).
Follow the GFCI wiring diagram on the next page.
Have your dealer or installer set DIP switch #6 to
•
the OFF position on the circuit board as shown at
right.
