This page provides the full exploded-view diagram and numbered bill of materials (BOM) for the Hydro-Pro Inverter Heat Pump Type PX7/32 (factory reference 7028283). The PX7/32 is a horizontal, R32-refrigerant, inverter-driven pool heat pump rated for pools of approximately 20–35 m³, running on a single-phase 230 V AC supply and fitted with a Mitsubishi inverter rotary compressor. Using the diagram alongside the parts list below, you should be able to locate and identify the component you need within a few minutes, whether you are a pool owner carrying out routine maintenance or a technician diagnosing a fault.

Com utilitzar el diagrama numerat per trobar la teva peça

Every call-out number printed on the exploded-view diagram corresponds directly to a numbered row in the parts list on this page, so start by locating the area of the unit where your suspect or damaged component sits — for example, the fan assembly at the top, the refrigerant circuit in the centre, or the electrical box on the side. Once you have identified the relevant area, find the call-out number that points to your component, then match that number to the same row in the BOM to read the full part description and, where available, the SKU you need to add to your basket. Bear in mind that some positions do not yet carry a purchasable SKU — these are structural or refrigerant-circuit parts that are not normally sold as individual service items. Pay close attention to the description in each BOM row: dimensions, thread sizes, electrical ratings, and model sub-codes are included precisely because similar-looking parts differ in critical ways. Where a position references more than one SKU in its description — as is the case with position 17, which lists the high-pressure switch alongside two separate temperature sensor options — read the full description carefully to determine which of those sub-items applies to your fault before ordering. Finally, confirm the factory reference 7028283 on your unit’s data plate to be certain you are working from the correct diagram before ordering any part.

Main replaceable assemblies on the Hydro-Pro Heat Pump Type PX7/32

The PX7/32 is built around five principal functional areas, each containing serviceable parts. The fan assembly — comprising the plastic fan net (pos. 3), the 405 mm × 134 mm anticlockwise fan blade with its 7 mm bore (pos. 4, SKU 7024879), the 40 W ZWS40-E51 fan motor (pos. 6, SKU 7029495), the fan motor bracket (pos. 10), and the fan protection net (pos. 8) — is responsible for drawing ambient air across the evaporator (pos. 9). The refrigerant circuit includes the Mitsubishi SVB140FCAMC inverter rotary compressor (pos. 29), the 4-way reverse valve for heating and cooling modes (pos. 23), the electronic expansion valve (pos. 20), the 3-way valve (pos. 19), the filter (pos. 22), and the low- and high-pressure switches (pos. 15, SKU 7011009, and pos. 17, SKU 7011008). The water-side heat transfer is handled by the titanium heat exchanger PIV 7/32 (pos. 27, SKU 7029496), which is the primary interface between the refrigerant and pool water and is specifically sized for this model. The water flow switch (pos. 18, SKU 7006471) protects the unit by confirming adequate water circulation before the compressor is permitted to run. Control and monitoring functions are provided by the CM404 glass display panel (pos. 2, SKU 7029494), the centrcentralised controller 82300052 + 82400021 (pos. 30, SKU 7029485), the high-pressure switch and temperature sensors referenced at position 17, and the R32-rated pressure gauge (pos. 25, SKU 7026259), which is calibrated for the 0–55 bar range appropriate to R32 refrigerant. The outer structure — front frame (pos. 1), top lid 956 × 360 mm (pos. 12, SKU 7033047), right side plate (pos. 26), and chassis (pos. 28) — houses and protects all internal assemblies.

Tria entre variants i mides de paquet

Several positions in this BOM reference specific sub-variants that must be matched precisely to your unit. Position 17 is the most notable example: while the high-pressure switch (SKU 7011008) is the primary orderable item listed there, the same position description also references two temperature sensor options — a 5 K sensor (SKU 7011007) and a 50 K sensor (SKU 7024867) — so you should check the sensor markings on your existing component or your service documentation before ordering. Position 4 specifies the fan blade direction (anticlockwise) and bore diameter (7 mm); fitting a blade with the wrong rotation or hole size will result in reversed or inadequate airflow and potential motor damage. The titanium heat exchanger at position 27 is designated specifically for the PIV 7/32 variant, so even though visually similar exchangers exist across the PX range, the internal geometry and port sizing differ between models and must not be substituted. Where you are unsure whether a part from another model in the PX family will fit the PX7/32, always cross-reference the factory reference 7028283 on the data plate and contact our team before ordering.
