Electrical Wiring
Correct wiring of the electrical service box, GFCI box and pack terminal block is essential.
1• Carry out a visual inspection to check for signs of miswiring.
Refer to supplied wiring diagrams. Call an electrician if necessary.

GFCI Trips!
4• If GFCI still trips, replace transformer.If it stops tripping, reconnect one component at a time until GFCI starts to trip. Replace defectivecomponent.
1• Verify if GFCI is properlyconnected.
3• If GFCI is properly connected, butstill tripping, unplug all outputs includingheater and light cord wires.
If all connections are made, but nothing seems to be working, you probably have a power supply problem. Carry out the following tests to identify and correct the problem:
Note that for new installations, GFCI trippings due to miswiring are common.
If breaker is wired properly, GFCI trippings may occur when total amount of current drawn by spa exceeds breaker rating. This is highly unlikely as each spa pack outputis individually fused, and fuses will blow before GFCI trips.
A current leak to ground will also cause GFCI to trip. If any of the components is faultyand a leak of more than 5mA occurs, the GFCI will trip to prevent electrocution.
There are different GFCI models on the market. Note that illustrations are examples only.
From electrical box To spa
2• If it is not, verify GFCI wiring diagram and reconnect it.
From electrical box To spa
Important connections:
Neutral of GFCImust be connected to neutral bus.
Neutral from spamust be connected to breaker.

GFCI Trips!
1• Disconnect incoming powerlines.
If GFCI still trips, there mustbe a cable problem.
Call an electrician!
2• If GFCI stops tripping. Replace GFCI.
3• If GFCI trips again, replaceboard. (Refer to "How toReplace the Board" sectionof this manual.)
If GFCI continues to trip even after having replaced the transformer,carry out the following tests to correct the problem:

If the user turns on a pump, blower or light during a filter cycle, the cycle will be interrupted andwill only resume 40 minutes after last active output has been turned off (automatically or manually).This delay is to prevent excessive ozonator activation.
During this interval, "Filter cycle" icon will flash in a different sequence (On: 1/2 sec., Off: 1/2 sec.,On: 1/2 sec., Off: 1 1/2 sec.).
Also, to prevent excessive water temperature caused by overly long filter cycles, the system willcancel a filter cycle after 3 hours if water temperature rises more than 2°F above set point. In thiscase, "Filter Cycle" icon flashes on display.
