Sticker on the pump body (the part with the basket), not on the motor. Motor labels from Century, A.O. Smith or Regal won't match parts.
Label on the side of the tank near the base. Size is in sq ft, e.g. 420 sq ft = C4030 or CCP420.
Rating plate inside the front access panel. Note the BTU and gas type (NG or LP).
Molded into the body or printed on top. Robotic cleaners: on the power supply.

Built InSet temperature, schedule, and switch modes from the Moov app.
Whatever the Pool Needs. Two rotors share the load so the compressor runs balanced at any speed with no shaking. Cold water at the start of the season, it runs wide open. Once you are at temperature it settles into a low-speed hum that sips power. Smart mode picks the speed for you. Silence mode caps it for nights and early mornings.
- Full-inverter compressor and fan, both variable speed
- Smart mode for fastest heat-up, Silence mode for quiet hold
- Reversible-valve defrost keeps it heating down to 32°F air
- AHRI-tested performance
Both Ends of the Season. The second-generation X-Inverter reverses its refrigerant cycle on command, so the same unit that heats the pool in spring pulls heat out of it in August. Inside, the heat exchanger is a titanium spiral sealed in PVC with 30% more surface area than a straight tube. Salt water, high chlorine, low pH, none of it touches metal that can corrode. Outside, an aluminum casing replaces the plastic shell of the first generation and shrugs off sun and rain for years on the pad.
- Heat, Chill, and Auto modes from the panel or the app
- Titanium-in-PVC spiral exchanger inside an aluminum casing
- 2-inch unions, 30 amp breaker on both models
- Side-fan horizontal discharge, only 16.5 in deep
- R32 refrigerant, 208-230V single phase
Go by pool volume first. The MXI650 is rated for pools up to 18,000 gallons and the MXI900 up to 28,000. If you are near the top of the MXI650 range, have a spa on the same loop, or want to swim in the shoulder season in Southern California, step up to the MXI900. Undersizing a heat pump means it runs at 100% more of the time, which erases the inverter savings. Both run on the same 30 amp breaker, so the electrical does not change.
Moov rates the Inverter at 30 to 50 percent lower seasonal energy use than a single-speed heat pump of the same BTU. The savings come from holding temperature at low speed instead of cycling on and off at full power. Actual numbers depend on your climate, pool cover use, and set temperature.
Yes. The heat exchanger is titanium sealed in PVC, which does not corrode from salt or chlorine. That is what the 10-year exchanger warranty is backing.
No plug. Both models are hard-wired 208-230V single phase on a 30 amp breaker with 10 AWG wire. A GFCI is not required for the unit to run, but if your local code requires one, some GFCI breakers nuisance-trip on variable-speed equipment, so confirm the breaker type with your electrician. Installation must be done by a licensed professional to keep the warranty.
Moov rates the second-generation X-Inverter at 34 dB(A) in Silence mode at 10 feet. That is quieter than a whisper and well below a household refrigerator. A single-speed heat pump of this size typically runs 65 dB or more, which is closer to a window air conditioner.
Yes. The MXI650 and MXI900 are reversible heat pumps. Select Chill mode and the refrigerant cycle runs backward, moving heat out of the pool water into the air. In Auto mode it holds your set point in either direction, heating on cool mornings and chilling through a heat wave. Air still discharges horizontally out the front, so leave 20 inches of clearance and keep the discharge side open.
