ALERT
Your new spa's GFCI will trip.
A Ground Fault Interrupter (GFCI) Trip Test must occur to
allow proper spa function.
Spas that come with MXBP20 and MXBP501 control sys-
tems come with special instructions for the installer/
electrician. If they have not already advised you on what
to do or expect from the GFCI Trip Test, please contact
them for instructions.
If the GFCI breaker connected to your spa trips, this is
normal behavior. Please reset the breaker and enjoy
your spa. The trip test has been completed successfully.
If your spa was not wired to a GFCI breaker or your
breaker fails the GFCI Trip Test, the spa will repeatedly
attempt (at preset intervals) to trip the breaker in the fu-
ture until such time that it triggers a GFCI Trip. If a GFCI
does not trip properly, your spa's display will show an
error message.
GFCI breakers are important safety devices required by
code for your hot tub. For more information, refer to the
MXBP20 and MXBP501 sections of this manual or your
local dealer.

Questions and answers
PUMP MUST BE TURNED ON MANUALLY TO HEAT HOT TUB
The MAAX 300 Series hot tub pump needs to be turned on manually to heat because the spa enters Priming Mode when powered up. During this 4-minute mode, pumps can be turned on and off to remove air from the plumbing lines and heater. Proper water flow must be verified before heating can begin. Additionally, maintaining full water flow is necessary for the heater to function effectively.
