Zodiac - PX50 MD3 Full-Inverter Pool Heat Pump - WH000428

Zodiac – PX50 MD3 Full-Inverter Pool Heat Pump

The Zodiac PX50 MD3 is a full-inverter pool heat pump with a heating capacity of 6.3 – 1.9 kW (air 15 / water 26). It runs on 220-240 V / 1 / 50-60 Hz, connects with a glued PVC 1/2 union – Ø 50 and measures 859 x 357 x 641 mm.

How the PX50 heats your pool

The PX50 is an air-source pool heat pump. It takes heat from the outside air and passes it to the pool water. The warmer and more humid the air, the better it performs, and reaching the set temperature can take several days depending on the weather, the output of the heat pump and the gap between the water temperature and the target.

Full inverter technology means the compressor (rotary vane) and the DC fan both run at variable speed, so output follows the power actually needed, which keeps the unit quiet and economical. The range offers 8 power levels, from 6.3 kW to 24 kW (air 15°C / water 26°C / humidity 70%), for small and large pools alike.

The patented titanium heat exchanger is compatible with salt water treatment.

Power modes and control

Intelligent heating regulation lets you choose how the heat pump uses its power:

• Boost: maximum power for fast heat-up
• Smart: automatic power adjustment depending on temperature
• Ecosilence: reduced power for further energy savings and the lowest noise level

The detachable LCD display shows and sets the operating mode. Further functions include a timer mode, a heating priority mode that controls the filtration pump, automatic defrosting and an automatic cooling mode (reversing cycle). Control via the iAquaLink®+ app is possible with the optional iQBridge RS WiFi gateway.

Build and accessories

The body is galvanised steel painted with epoxy, with ABS cladding. Air is blown out horizontally, and the unit stands on anti-vibration feet.

The manufacturer lists a winter cover, a control kit with cable, a condensate drain kit and glued PVC 1/2 union connections for the Ø 50 hydraulic connection among the accessories for the range. A PAC Net cleaning kit and the iQBridge RS WiFi gateway are optional.

Instal·lació i manteniment

Installation and electrical connection must be carried out by a qualified installer in line with the manufacturer’s instructions and local regulations. The heat pump is for outdoor installation only, on a stable, level surface, and the electrical supply needs its own protection and isolation device.

The hydraulic connection is made in glued PVC Ø 50 on the filtration circuit, after the filter and before the water treatment, with a bypass fitted to make servicing easier. The unit gives off condensate while running, so a condensate drain should be connected.

Keep the evaporator clean. Any work on the refrigerant circuit, including the yearly leak check, is for a qualified specialist.
