*PROVIDED WITH SPA. NOTE: ALL WIRING SHOULD BE COPPER.
NOTE: The wire connections to GFCI breakers are for reference only. Always ensure the
white neutral wire is connected to the load neutral of the 30 amp breaker.
WARNING! The exact physical location of the terminals
on the GFCI breaker will vary between manufacturers.
Connecting the hot wire to the neutral terminal will
cause irreversible damage to the control box.

All230voltHotSpring
spas must be wired in accordance with applicable local and national electrical codes, all
electrical work must be done by a licensed electrician.
NOTE: Watkins Manufacturing Corporation RE QUIRES THE USE OF A SUBPANEL TO SUPPLY POWER AND
PROTECT THE SPA. On the GRANDEE, ENVOY, VANGUARD, ARIA and SOVEREIGN models, the subpanel
containingGFCIbreakersisincludedwiththespa.Onthe230voltJETSETTER model, the subpanel containing
GFCI breakers must be purchased separately and can be purchased from your HOT SPRING dealer.
A licensed electrician should install a four-wire electrical service (two line voltages, one neutral, one ground) from
the main electrical service panel to the subpanel, and from the sub-panel to the spa per the appropriate wiring
diagram as illustrated below.

WARNING: Removing or bypassing the GFCI breakers in the subpanel at any time will result in an unsafe spa and
will void the warranty.
WIRE SPECIFICATION NOTE: Long electrical runs may require a larger gauge feed wire than stated. We
recommend that a maximum voltage drop of 3% be used when calculating the larger wire size.
