The Y Series packs are equipped with a
GFCI/RCD
tripper circuit in case an HL error occurs.
• Find the GFCI/RCD tripper circuit (J1) on the board
located behind the temperature probe and remove
the jumper
• Reset the GFCI/RCD and see if an error occurs
If HL appears, follow the HL error troubleshooting
chart (in the Troubleshooting section)
• If no error occurs, re-install the jumper
Note: If the GFCI/RCD trips only when jumper (J1) is
installed, replace the spa pack.
From

To spa
Important
connections:
Neutral of
GFCI /RCD
must be
connected to
neutral bus.
Neutral from
spa must be
connected to
breaker.
The GFCI/RCD trips and the jumper (J1) is not installed,
the error doesn’t come from the GFCI/RCD tripper
circuit.
• Verify that the GFCI/RCD circuit is properly
connected
• If it's not, reconnect it
• Verify the spa pack wiring (make sure that the neutral
and the ground have not been inverted)
If the GFCI/RCD is properly connected but still tripping,
• Unplug all outputs from the spa pack (pumps, blower,
heater, ozonator etc)
• If it doesn't trip while all outputs are unplugged,
reconnect one output at a time until the GFCI/RCD
trips again
• Replace defective component
GFCI/RCD (J1)
Note: Incorrect GFCI/RCD wiring may lead to a condition where the GFCI/RCD may NOT trip when it should, causing
electrical shock hazard. All electrical installations should be done by qualified personnel only.
