GFCI Protection
Your spa may be equipped with a GFCI Protection
feature. If your spa does have this feature enabled, the
GFCI Trip Test must occur to allow proper spa function.
Within 1 to 7 days after startup, the spa will trip
the GFCI to test it. (The number of days is factory
programmed.) The GFCI must be reset once it has been
tripped. After passing the GFCI Trip Test, subsequent
GFCI trips will indicate a ground fault or other unsafe
condition requiring the power to the spa to be shut off.
GFCI Trip Test Procedure
The installer can cause the GFCI Trip Test to
occur sooner by initiating it with the following
button sequence.
Press “Warm”, then “Jets 1”, then “Light.” (Each press
must be within 3 seconds of the previous press.) Press
the “Warm” button repeatedly until “
” is displayed.
Press “Jets 1” to select it. Press the “Warm” button until
“
” is displayed. Press “Jets 1” to initiate the GFCI
Trip Test.
The GFCI should trip within several seconds and the spa
should shut down. If it does not, shut down the power
and manually verify that a GFCI breaker is installed and
that the circuit and spa are wired correctly. Verify the
function of the GFCI with its own test button. Restore
power to the spa and repeat the GFCI Trip Test.
Once the GFCI is tripped by the test, reset the GFCI and
the spa will operate normally from that point. You can
verify a successful test by navigating to the “
” item
as described above, pressing “Jets 1” and then pressing
the “Warm” button until you see “
”. The code
signifies GFCI Status - Passed.
The system will exit this menu in 30 seconds if no
buttons are pressed.
Warning: The Owner should test and reset the GFCI
on a regular basis to verify its function.
Note:
The GFCI section does not apply on EL systems used outside the United States.
