If any alarms appear during initial startup, read the instructions provided in the following table. If the solution is not
possible, immediately contact the Manufacturer to request technical support. In the meantime, do not try to repair
or use the minipool but rather disconnect it from the electricity and water supplies.

DESCRIPTION OF THE PROBLEM
POSSIBLE SOLUTIONS
HI-43
Temperature
alarm
(notication)
Problem description: if the water temperature in the minipool exceeds
42°C all the functions are deactivated, the display shows the "HI"
message alternating with the temperature value.
Solutions : the alarm and the system will automatically reset when the
temperature drops. If the alarm does not reset contact the Manufacturer.
Er
Temperature
sensor alarm
(alarm)
Problem description: a temperature sensor measures the water
temperature inside the minipool, activating the heater when necessary.
The allowed water temperatures range from 5°C to 45°C. Values outside
the range cause the blocking of all functions and the permanent activation
of the alarm message.
Solutions: the alarm will reset automatically once the temperature
returns to allowed values (5° to 45°). The message is also displayed if
the temperature sensor malfunctions.
Solutions : make sure that the water temperature is not outside of the
permitted values, try to disconnect the power supply to the bathtub
and switch it on again after 30 seconds. If the problem persists, verify
that the connection with the control unit is correct and has not been
tampered with. Otherwise contact the Manufacturer.
FLO
No ow alarm
(notication)
Problem description: the notication protects the heater and the
recirculation pump from running in the event of potential danger. It is
activated when the recirculation pump is running, the ow switch does
not detect ow for at least ve seconds. The display shows the message
"FLO" alternating with the temperature, the heater is disabled and the
recirculation pump remains active for a maximum of ve minutes, after
which an automatic backwash of the sand lter is initiated.
Solutions: the notication will automatically reset when ow is restored,
otherwise a new alarm will be triggered (see FL alarm).
FLC
No ow alarm
(alarm)
Problem description: the alarm is activated if the flow sensor
malfunctions. The system disables the heater even if the recirculation
pump remains active.
Solutions : try to disconnect the power supply to the tub and switch
it on again after 30 seconds. If the problem persists, verify that the
connection with the control unit is correct and has not been tampered
with. Otherwise contact the Manufacturer.
Fl
Clogged filter
alarm
(alarm)
Problem description: the alarm occurs when, after a lter backwash,
lack of ow continues for more than 5 minutes (see "FLO" notication).
The system stops, all functions are disabled and the display shows the
xed "FL" alarm.
Solutions: The alarm resets only by switching off the minipool and turning
it back on after about 30 seconds.
The main causes of what has been described are attributable to:
1
Damage to the circulation pump. Once the minipool restarts, verify
that the circulation pump functions correctly. Try to perform a manual
backwash of the lter (see page 20);
2
Excessive dirtiness of the sand in the lter due to an incorrect
treatment of water in the minipool (see the section on water
treatment on page 13). In this second case, empty the minipool,
disassemble the lter and check the sand. Depending on the
problem found when the lter was opened use suitable products
to wash the sand. Finally, replace the sand (see page 8).
