WIRING CHECK PRECAUTIONS
When working in a system box always be aware that it UÊ
may contain high voltage.
Always keep your fingers and hand tools away from any UÊ
wiring or circuit board when the power is on. Touching
anything in these areas can result in serious injury.
All service calls, no matter how minor, should UÊ
include a complete wiring check, beginning with the
house breaker.
CHECK FOR LOOSE CONNECTIONS OR
DAMAGED WIRES
Make sure the power is off before you touch any wiring.UÊ
Once the power is off, carefully examine all wires for UÊ
cuts or defects.
SYSTEM BOX WIRE GAUGE CHECK
When inspecting the wiring for any control system, note
that connections for the incoming wires are clearly labeled
at the main terminal block.
30A service – minimum ten gauge copper wire.UÊ
These wires must connect the house breaker box,
through the local disconnect, to the main terminal block.
The wiring diagram inside the system box shows the main
terminal block as TB1.
IMPORTANT -- USE OF NON-COPPER WIRE
Using non-copper wire can be dangerous, and also can be
the cause of a spa’s malfunction. If non-copper wire
is used at any point, we do not recommend servicing the
spa until an electrician replaces it with the proper gauge
copper wire.
