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,
UÊ
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,
UÊ
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.
