Correct thermal sizing requires calculating the cubic volume of the water and allowing for a power margin based on the local climate and use of a thermal cover. The following technical guidelines apply to standard residential installations:

• Pools up to 25 to 35 m³: require units with nominal capacities between 7 and 9 kW to maintain 28 °C during a standard season.
• Pools from 40 to 60 m³: require 11 to 14 kW capacities to compensate for nighttime evaporation losses.
• Pools from 65 to 90 m³: require 16 to 21 kW units connected to pipes with a 50 mm bypass.

An undersized calculation with no safety margin causes the compressor to run continuously at maximum frequency, eliminating the modulation benefit that characterizes inverter systems.

Full-inverter systems dramatically reduce sound pressure by adjusting the fan and compressor speed once the target temperature is reached. Instead of switching off and starting up abruptly, the equipment runs at 20% or 50% of its nominal capacity, keeping the sound level below 40 dB measured at a distance of 1 meter while running at cruising speed. This continuous adjustment minimizes mechanical vibrations and prevents current surges that drive up electricity costs. In addition, the airflow direction disperses the sound without blowing directly toward nearby relaxation areas.

Adding a heat pump to the technical system requires a bypass connection using three 50 mm PVC valves downstream of the filter outlet. This setup allows you to regulate the exact flow rate, in cubic meters per hour, entering the titanium heat exchanger and isolate the unit for maintenance without stopping filtration. If the main pump does not provide sufficient flow, the internal flow sensor will prevent startup as a safety measure to prevent overheating in the R32 refrigerant circuit.

Thanks to frequency modulation, these units achieve COP values above 10 to 15 under favorable ambient conditions. This means that for every kilowatt of electricity drawn from the grid, the system transfers between 10 and 15 kilowatts of heat to the pool water. To maintain this high thermal performance in colder months, a thermal cover must be used at night to prevent heat loss from the water’s surface. When outdoor temperatures are low, the system activates hot-gas defrosting to keep the evaporator free of frost without stopping heating for an extended period.

To sync with the Fairland Smart Pool mobile app, connect the main unit to your home 2.4 GHz Wi-Fi network using any smartphone. Once the device is linked, the software lets you perform the following operations:

• Real-time reading of the current temperature and immediate adjustment of the desired setpoint.
• Remote selection of operating modes based on the priority between acoustic silence and rapid heating.
• Set daily timers to coordinate start-up with peak sunlight hours or lower electricity rates.

This connectivity makes it easy to monitor possible flow warnings or technical errors directly on screen without having to operate the external display.

Cordless robots eliminate the risk of tangles in the floating cable and do not overload the electrical system near the pool. Models such as those in the InverX Air series feature lithium batteries that provide 2 to 3 hours of continuous operation, depending on the selected cycle. While a traditional hydraulic pool cleaner relies on the suction power of the sand filter, a battery-powered unit operates completely independently, collecting fine particles and leaves in its internal basket. At the end of the floor and wall cleaning cycle, the robot automatically moves toward the edge to make it easier to remove.

Winterizing the machine requires completely draining the water retained in the condenser to prevent damage from severe frost. First, disconnect the unit from the main power supply. Next, close the bypass inlet and outlet valves and loosen the union fittings to drain the remaining liquid from the titanium heat exchanger. It is advisable to protect the outer casing with a breathable cover that prevents dirt and leaves from accumulating on the fan grille during the months when the unit is not in use, ensuring a clean, unobstructed start-up the following swimming season.
