Pompe à chaleur Hydro-Pro, modèle Z à inverseur (type Z19/32) : vue éclatée et pièces de rechange

Cette page présente le schéma éclaté complet et la nomenclature du Hydro-Pro Heat Pump, Type Z Inverter, model Z19/32 — factory reference 7024519. The diagram covers every serviceable position across the entire unit, from the outer casing panels and fan assembly through to the refrigerant circuit, titanium heat exchanger, and electronic control box. It is designed for use with the ABS-bodied, R32-refrigerant, 230 V single-phase variant of the Type Z Inverter range. Whether you are a pool owner carrying out routine sensor maintenance or a qualified technician tracing a fault through the refrigerant or water circuit, you should be able to identify the exact part you need within a few minutes of consulting the diagram alongside this parts list.

Comment utiliser le schéma numéroté pour trouver votre pièce

Every numbered call-out on the diagram corresponds directly to a row in the parts table below, so the two should always be read together. Start by locating the area of the unit where you observed the fault or wear — for example, the water-side connections at the bottom of the unit, or the fan assembly at the top — then find the matching call-out number on the diagram. Once you have the position number, look up that row in the table to retrieve the SKU, which is what you need to add the correct item to your basket. Bear in mind that a small number of positions — such as clips (pos. 12 and 32) and magnetic rings (pos. 67 and 68) — share the same generic description but appear in different physical locations on the unit; always confirm the location on the diagram before ordering. Pay particular attention to lettered variants: position 22 splits into 22a et 22b, which are two different display assemblies that are not interchangeable. Positions without a SKU listed are structural or refrigerant-circuit components (panels, pipework, valves) that are not individually stocked as retail spare parts; if you require one of these, please contact us directly. Finally, always note any specification detail given in the description — connector pin-counts, voltages, dimensions, and pressure ratings are included precisely because they determine compatibility.

Main replaceable assemblies on the Hydro-Pro Type Z Inverter (Z19/32)

Le fan and airside assembly sits at the top of the unit and comprises the fan motor (pos. 15, ZWB378D02B, 120 W) and the fan blade (pos. 16, 554 mm × 148 mm, 10 mm bore, anticlockwise rotation), both of which are individually available as spares. The fan motor is mounted on a dedicated bracket (pos. 14) and draws ambient air across the evaporator (pos. 5); the ambient temperature sensor TH1 (pos. 2) clips to this zone to monitor incoming air conditions. The circuit de réfrigérant runs from the compressor (pos. 24, model MVB33FBPMC) through the 4-way valve (pos. 50), the electronic expansion valve (pos. 54), the liquid reservoir (pos. 27), the filter (pos. 45), and a network of interconnecting pipes (pos. 30, 40, 42, 44, 46, 48, 51, 52, 53, 55). Circuit health is monitored by a low-pressure switch (pos. 43, 0.1–0.3 MPa) and a high-pressure switch (pos. 47, 3.6–4.2 MPa), both of which are stocked as individual spare parts, as is the R32 pressure gauge (pos. 33, 0–65 bar). Cold-weather protection for both the evaporator and compressor is provided by heating belts: the evaporator heating belt (pos. 13, 230 V 65 W 2000 mm) and the compressor heating belt (pos. 26, 230 V 35 W 430 mm). The circuit côté eau centres on the titanium heat exchanger specific to this model (pos. 61, Z19/32) and is instrumented by three temperature sensors — water-in TH6 (pos. 58), water-out TH5 (pos. 63), and the pipe temperature sensor TH2 (pos. 8) — together with a water flow switch (pos. 65, VH-2). The electronic control system lives in the electric box (pos. 69) and is governed by the main inverter board (pos. 70, HWM1W-5D00 IB030R3A); the exhaust temperature sensor TH3 (pos. 49) monitors discharge-gas temperature at the compressor outlet and is a common service item. The outer structure — top cover (pos. 1), front panel (pos. 18), left panel (pos. 17), right panel (pos. 36), back panel (pos. 41), and back grill (pos. 4) — protects all internal assemblies and is supported by the upper frame (pos. 11) and base tray (pos. 23).

Choix entre les différentes variantes et les formats d'emballage

Le choix de variante le plus important sur ce schéma se situe à position 22, where two mutually exclusive display assemblies are listed: 22a is the LED display (SHHCLEDV2MM101, SKU 7021826) and 22b is the colour TFT display (TSiV1, SKU 7025263). These are different controller interfaces fitted to different production batches of the Z Inverter range; you must match the replacement to the display type already installed on your unit, as they are not electrically or mechanically interchangeable. For the three temperature sensors at positions 2, 8, 49, 58, and 63, all share a 6×4 plug format, while the water flow switch at position 65 uses a 9×7 mm plug — double-checking the connector specification before ordering avoids a wasted return. The compressor heating belt (pos. 26) uses an 8×4 plug, which again differs from the sensor connectors, so connector pin-count is a reliable cross-check. Where description fields include dimensions — such as the fan blade’s 554 mm × 148 mm with a 10 mm bore (pos. 16) — these details exist because even a small deviation in diameter or bore size will prevent correct fitment or produce dangerous imbalance at running speed, so never substitute a nominally similar blade without verifying all three measurements.
