Bomba de calor Norsup, tipo inversor (modelo Xp17Dcsi): vista explosionada y piezas de recambio

Norsup Heat Pump Inverter (Type XP17DCSI) exploded view & spare parts

This page presents the full exploded-view diagram and bill of materials (BOM) for the Norsup Heat Pump, Type Inverter — model XP17DCSI, covered under Norsup factory reference 7021078. The diagram shows every serviceable component of this full-inverter pool heat pump — from the outer casing and fan assembly through to the refrigerant circuit, titanium heat exchanger, and control electronics. Whether you are a pool owner carrying out routine maintenance or a technician diagnosing a fault, the numbered diagram and the parts list below will help you identify the exact component you need in just a few minutes. If your unit carries the XP17DCSI designation, every position number shown applies directly to your machine.

Cómo utilizar el esquema numerado para localizar tu pieza

Every numbered call-out printed on the diagram corresponds precisely to a row in the parts list below — locate the area of the heat pump where the fault or wear has occurred, then find the matching position number in that zone of the diagram. Once you have the position number, read across the row in the BOM to find the part description and, where one is shown, the SKU you need to add to your basket. Bear in mind that some components do not yet carry an individual SKU — this is indicated clearly in the list — and in those cases we recommend contacting our team for availability. Pay particular attention to positions that use letter suffixes: for example, position 20a y 20b describe two different LED display variants for the same mounting location, so choosing the wrong letter will result in an incompatible part being ordered. Similarly, positions 42 y 43 are both low-pressure switches fitted at the same area of the refrigerant circuit but set to different pressure ranges, so always cross-check the pressure rating stamped on your existing switch before ordering. Positions 58 y 63 share the same SKU (7014153, Water connection set), because the same part is used at both the inlet and outlet sides — ordering one SKU is correct for either location. When in doubt, photograph the part in situ alongside the diagram call-out before placing your order.

Main replaceable assemblies on the Norsup Heat Pump Inverter (Type XP17DCSI)

El montaje en zona de operaciones occupies the upper section of the unit and centres on the evaporator (pos. 5), which absorbs heat from the ambient air, supported by the back grill (pos. 4) and top cover (pos. 1). Airflow is generated by the fan motor (puesto n.º 13, ZWB378D02B 120 W, SKU 7021812) driving the fan blade (pos. 14, 554 mm × 148 mm with a 10 mm anticlockwise-rotation bore, SKU 7021816) — both are individual line-replaceable items. The circuito de refrigerante runs from the compressor (pos. 23) through the four-way valve (pos. 48), the electronic expansion valve or EEV (pos. 50), the fluid reservoir (pos. 24), and the filter (pos. 38), with circuit integrity monitored by the low-pressure switches at positions 42 y 43 and the high-pressure switch at position 45 (SKUs 7024791, 7024792, and 7024793 respectively). The compressor heating belt (pos. 25, 230 V / 35 W / 320 mm, SKU 7020269) protects the compressor during cold starts and is a straightforward seasonal-maintenance item. The water-side assembly is built around the titanium heat exchanger (pos. 57, SKU 7021830), which transfers heat to the pool water, sealed and connected via the water connection sets at positions 58 y 63 (SKU 7014153). Water flow is monitored by the flow switch at position 61 (VH-2 with 9×7 mm plug, SKU 7020257), and inlet and outlet temperatures are tracked by the sensors at positions 54 y 59 (SKUs 7020263 and 7020262). The control and display assembly comprises the main PC board (pos. 66, SH0300101-V1.5, SKU 7021836) housed in the electric box (pos. 64), the waterproof display box (pos. 19, SKU 7010543), and the LED display module at position 20. Temperature monitoring across the refrigerant circuit is handled by three plug-type sensors: the ambient sensor TH1 (pos. 2, SKU 7020259), the pipe sensor TH2 (pos. 8, SKU 7020260), and the exhaust sensor TH3 (pos. 51, SKU 7020261), all sharing the same 6×4 mm plug format.

Elegir entre variantes y tamaños de envase

The most significant variant choice on this model is at position 20, where the LED display is available in two versions: 20a (SHHCLEDV2MM101, SKU 7021826) is the standard inverter display, while 20b (WiFi02iMM011, SKU 7023600) is the Wi-Fi-enabled version — the two are not interchangeable, so check your existing display board’s part number before ordering. The pressure switches at positions 42 y 43 are another variant pair: one is rated 0.1–0.3 MPa and the other 0.2–0.35 MPa; fitting a switch with an incorrect pressure range can cause nuisance trips or, conversely, fail to protect the circuit, so always verify the rating on the original switch. All three temperature sensors (positions 2, 8, y 51) share the same 6×4 mm plug format, but they are assigned to distinct monitoring points in the refrigerant circuit — while they may look physically identical, always order by position number and SKU to ensure the correct calibration range for that sensor location. The water connection sets (positions 58 y 63, SKU 7014153) are identical parts, so a single SKU covers both the inlet and outlet positions; if you are replacing both at once, simply order a quantity of two.
