GFCI Test Feature
The Ground Fault Circuit Interrupter (GFCI) or Residual Current
Detector(RCD) is an important safety device and is required
equipment on a hot tub installation.
(The GFCI Test Feature is not available on CE rated systems).
Used for verifying a proper installation
Your spa may be equipped with a GFCI Protection feature. If
your spa has this feature enabled by the manufacturer, the
GFCI Trip Test must occur to allow proper spa function.
On some systems:
Forcing the GFCI Trip Test
(North America Only)
Touching the GFCI Test Icon on the Utilities Screen
takes
you to the GFCI Test screen.
The installer can cause the GFCI Trip Test to occur sooner
by pressing Test on the GFCI Test screen.
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 above screen.
“Passed” should appear after the Reset line is selected on
the GFCI screen.
Warning:
On those systems that automatically test the GFCI within 1 to 7
days after startup:
The end-user must be trained to expect this one-time test
to occur. The end-user must be trained how to properly reset
the GFCI. If freezing conditions exist, the GFCI or RCD
should be reset immediately or spa damage could result.
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 tripped. After passing the
GFCI Trip Test, any subsequent GFCI trips will indicate a
ground fault or other unsafe condition and the power to the
spa must be shut off until a service person can correct the
problem.
CE Product
CE registered systems do not have an RCD Test Feature due to
the nature of the electrical service. Some UL registered systems
do not have the GFCI Test Feature activated. The end-user must
be trained how to properly test and reset the RCD.
Reset Button:
Only use the Reset Button prior to moving the spa to a new
location. Pressing the Reset the button forces a new Test to be
performed at the new location.
General Messages
Most messages and alerts will appear at the bottom of the normally
used screens. Several alerts and messages may be displayed in a
sequence.
–– – – –°F – – – –°
Water Temperature is Unknown
After the pump has been running for 1 minute, the temperature will
be displayed.
Possible freezing condition
A potential freeze condition has been detected, or the Aux Freeze
Switch has closed. All water devices are activated. In some cases,
pumps may turn on and off and the heater may operate during
Freeze Protection. This is an operational message, not an error
indication.
The water is too hot – M029*
The system has detected a spa water temp of 110°F (43.3°C) or
more, and spa functions are disabled. System will auto reset when
the spa water temp is below 108°F (42.2°C). Check for extended
pump operation or high ambient temp.
The water level is too low
This message can only appear on a system that uses a water level
sensor. It appears whenever the water level get too low (or the
water level sensor is disconnected), and automatically disappears
when the water level is adequate. Pumps and the heater turn OFF
when this message appears.
