Hydro-Pro Heat Pump, Type Inverter (Type XP35DCSI+) exploded view & spare parts

This page presents the full exploded-view diagram and bill of materials for the Hydro-Pro Heat Pump, Type Inverter (Type XP35DCSI+), identified under factory reference 7018552. The diagram covers every major assembly and sub-component of this inverter-technology pool heat pump, from the refrigerant circuit and titanium heat exchanger through to the electronic control boards and display panels. The Hydro-Pro Inverter range uses a variable-speed compressor and fan motor to vary heating output according to ambient conditions, making precise part identification especially important when servicing. Using the numbered diagram alongside the parts list below, you should be able to pinpoint the exact component you need in just a few minutes.

Comment utiliser le schéma numéroté pour trouver votre pièce

Every call-out number printed on the exploded-view diagram corresponds directly to a numbered row in the parts list table below the image. Start by locating the general area of the unit where your fault or wear has occurred — for example, the refrigerant circuit at the rear, the electrical box on the right side, or the water connections and heat exchanger section — then trace the relevant call-out number within that area. Once you have the position number, find the matching row in the parts list; if a SKU is shown, that part is available to order directly. Be aware that some position numbers appear more than once on the diagram because the same component is used in multiple locations — position 63 and position 70, for instance, both refer to the same water connection set (SKU 7014153) fitted at the inlet and outlet respectively. Pay close attention to lettered suffixes: positions 27a et 27b share the same physical location on the diagram but refer to two different LED display variants, so selecting the wrong letter will result in an incompatible board being ordered. Where no SKU is listed against a position number, the part is either a structural panel or a refrigerant-circuit pipe assembly that is not supplied as a standalone spare; in such cases, please contact us before ordering. Always cross-reference the factory reference number 7018552 if you are unsure whether a part shown belongs to this specific model.

Main replaceable assemblies on the Hydro-Pro Heat Pump, Type Inverter (Type XP35DCSI+)

Le air-side assembly sits at the top of the unit and centres on the fan motor (position 19, SKU 7021813), a YDK-50-8GXX 50 W unit mounted via the fan motor bracket (position 18) and motor tube (position 20). The fan blade at position 21 (SKU 7010540) is a 490 mm × 125 mm clockwise-rotation blade with a 12 mm bore, and must be matched precisely to the motor to maintain correct airflow over the evaporator. Wrapped around the evaporator is the evaporator heating belt (position 17, SKU 7020274), a 230 V / 65 W / 2000 mm frost-protection element held in place by the clip at position 16 — this is a common service item during winter commissioning. The refrigerant circuit runs from the compressor (position 31) through the 4-way valve (position 55), electronic expansion valve (position 49), fluid reservoir (position 32), filter (position 48), and the various interconnecting pipe assemblies at positions 50–52 and 60–62. Protecting the high side of the circuit is the high-pressure switch (position 54, SKU 7024793, rated 3.6–4.2 MPa), while the low side carries one of two pressure switches — position 58 (SKU 7024791, 0.1–0.3 MPa) or position 59 (SKU 7024792, 0.2–0.35 MPa) — depending on the specific build variant. The water circuit connects to the pool via the water connection sets at positions 63 and 70 (both SKU 7014153), with the water flow switch at position 66 (SKU 7020258) monitoring flow and the titanium heat exchanger at position 72 (SKU 7021823) transferring heat to the pool water. Temperature monitoring across the water circuit is handled by the inlet sensor TH1 at position 68 (SKU 7020264) and the outlet sensor TH2 at position 73 (SKU 7020265). The electrical box (position 83) houses the inverter driver board at position 76 (SKU 7020768), the main inverter board at position 80 (SKU 7020764), and the relay at position 77 (SKU 7010519), all of which are serviceable items. The compressor is protected by its own frost-protection heating belt at position 33 (SKU 7020270), a 230 V / 35 W / 430 mm element that is considerably shorter than the evaporator belt and must not be substituted with it. A set of three temperature sensors covering ambient, pipe, and exhaust (TH3/TH5/TH6) is supplied together at position 53 (SKU 7020266) as a matched plug assembly.

Choosing between variants and pack sizes

The most important variant choice on this diagram is at position 27, where 27a and 27b designate two distinct LED display boards for the inverter control system: the SHHCLEDMM101 (SKU 7020256) and the WiFi02iMM011 (SKU 7023600). These are not interchangeable — selecting the wrong variant will result in a display that does not communicate with the main board. Check your existing display’s model code, printed on the board itself, before ordering. A similar consideration applies to the two low-pressure switches at positions 58 and 59: although they look identical externally, their calibrated operating ranges differ (0.1–0.3 MPa versus 0.2–0.35 MPa), and fitting the wrong rating can cause nuisance trips or, conversely, fail to protect the compressor. For the heating belts, positions 17 and 33 are both 230 V elements but differ in wattage and length — 65 W / 2000 mm for the evaporator and 35 W / 430 mm for the compressor — so always order by position number rather than by specification alone. Where sealing consumables such as the O-ring (position 65) or the blue and red rubber rings (positions 64 and 71) are concerned, verify the diameter against the mating connection before fitting, as the water connection sets at positions 63 and 70 share the same SKU but are installed at different points in the water circuit.
