The fill solenoid valve, which is activated on the control panel by holding down for 3 seconds, allows the water, which has already been mixed at the desired temperature, to flow into the hot tub. Filling takes place through the waterfall.
When filling of the hot tub begins, the message “L1” is displayed on the control panel, alternating with the water temperature, until water is detected for 3 seconds. Then, the panel displays “L2” while filling continues until it reaches the maximum level sensor (L2) for 10 consecutive seconds.
If the L1 and L2 sensors both detect water, the filling function is disabled.
See section 6.4. Water maintenance to see the specifications that should be considered regarding the water’s characteristics.
