To change the Spa water:
• Disconnect the electrical equipment, placing the differential switch (installed in the main input of the home) in the OFF position.
• Locate the drain valve (see 3.3 Drainage) and turn the valve to the OPEN position. The Spa will empty by gravity through the general drain.
• Once the Spa is empty, inspect the acrylic and clean if necessary (see point 6.5 Acrylic Maintenance). Turn the drain valve to the CLOSED position.
• Fill the Spa with clean water (see 3.4 Filling the spa)
