Your new Jacuzzi® spa is equipped with the J-1000™
system. It contains the most advanced safety and self-
protective equipment in the industry. Nonetheless, this spa
must be installed properly to ensure dependable usage.

Proper grounding is extremely important. Jacuzzi spas are equipped with
a current collector system. A pressure wire connector is provided on the
surface of the control box, located inside the equipment door (Figure B, page
13) to permit connection of a bonding wire between this point and any
ground metal equipment, metal water pipe or conduit within 5 feet (1.5m)
of the spa, or copper clad grounding rod buried within 5 feet (1.5m) of the
spa. Bonding wire must be at least No. 8 AWG (8.4 mm²) solid copper
wire. This is a most important safety assurance feature.
Before installing your spa, check with your local building department to
ensure installation conforms to local building codes.
