230 VOLT CONVERTED PRISM
The PRISM will require an additional 20 amp breaker in order to operate
the heater and jet pump 3 at the same time. Without the additional 20
amp breaker, the heater will NOT operate while the jets are used with jet
pump 3 on.
This subpanel requires a 70 amp, single phase, 230 volt, four wire
service (two line, one neutral, one ground). The ground wire must never
be less than #10 AWG. Use NEC 250-122 (table) and local codes for
more information. A minimum #6 AWG solid copper bond wire is also
required.
Mount the subpanel in the vicinity of the spa, but not within five feet, in
accordance with local codes.
HOT SPRING SPAS MUST BE WIRED IN ACCORDANCE WITH
ALL APPLICABLE LOCAL ELECTRICAL CODES. ALL ELECTRICAL
WORK SHOULD BE DONE BY AN EXPERIENCED LICENSED
ELECTRICIAN. WE RECOMMEND THE USE OF APPROPRIATE
ELECTRICAL CONDUIT, FITTINGS, AND WIRE FOR ALL CIRCUITS.
IMPORTANT: Service Technician must reconfigure spa using the soft
jumpers to allow spa heater to run concurrent with jet pump.
NOTE: Long wiring runs may require larger-gauge wire than stated.
