Norsup Heat Pump Inverter (Type XP26DCSI) exploded view & spare parts

This page covers the complete exploded-view diagram and bill of materials for the Norsup Heat Pump, Type Inverter — factory reference 7021080, model designation XP26DCSI. The diagram breaks the unit down into every serviceable component, from the outer casing panels through to the refrigerant circuit, electrical box, and water-side connections. Whether you are a pool owner carrying out routine maintenance or an experienced technician diagnosing a fault, the numbered parts list below will help you identify the exact component you need within minutes. Use the position numbers in the diagram alongside the SKUs listed here to order a confirmed match for this model.

Come utilizzare lo schema numerato per individuare il proprio componente

Every numbered call-out printed on the exploded-view diagram corresponds directly to a row in the parts table below — locate your area of interest on the drawing first, note the position number shown, then find that same number in the table to confirm the part description and SKU. Work from the outside in: start with the panel or sub-assembly group you are working on, narrow down to the specific component, and cross-reference the description to make sure it matches what you have removed from the unit. Bear in mind that some position numbers carry a letter suffix — positions 22a e 22b, for example, refer to two different LED display variants for this inverter model, so reading the full description carefully before ordering is essential. Position numbers 53 e 54 are a similar case: both are low-pressure switches, but with different pressure-rating ranges (0.1–0.3 MPa and 0.2–0.35 MPa respectively), and fitting the wrong rating can affect protection behaviour. Equally, positions 58 e 65 share the same SKU (7014153, water connection set) because the same component appears at two locations on the unit — this is normal and intentional. Where a position has no SKU listed, the part is either supplied only as part of a larger assembly or is not currently available as an individual spare; contact us if you are unsure.

Main replaceable assemblies on the Norsup Heat Pump Inverter (Type XP26DCSI)

Il fan and air-side assembly (positions 14–16) consists of the fan motor bracket, the fan motor (pos. 15, SKU 7021812, rated 120 W, model ZWB378D02B), and the 496 mm fan blade (pos. 16, SKU 7021815) — note the blade is anticlockwise rotation with a 12 mm bore, so direction matters when ordering a replacement. The refrigerant circuit runs through a 4-way valve (pos. 50), an electronic expansion valve or EEV (pos. 44), a fluid reservoir (pos. 27), filter (pos. 43), and a titanium heat exchanger (pos. 67, SKU 7021832), which is the primary point at which refrigerant energy is transferred to pool water. Refrigerant-side protection is provided by a high-pressure switch at pos. 49 (SKU 7024793, rated 3.6–4.2 MPa) and low-pressure switches at pos. 53 and 54, each available individually under their respective SKUs. The water-side circuit features a water flow switch (pos. 61, SKU 7020257), inlet and outlet temperature sensors (pos. 63, SKU 7020263; pos. 68, SKU 7020262), and an exhaust temperature sensor at pos. 48 (SKU 7020261) — all three sensors use a 6×4 mm plug format. The electrical box (pos. 78) houses the main PC board SHZKA0101 (pos. 76, SKU 7021837), driver board SHQ050101 (pos. 71, SKU 7021838), relay CJX9B-25S/D 220–240 V AC (pos. 75, SKU 7010519), filter board (pos. 74), and two magnet rings (pos. 72 and 73). The user interface consists of the waterproof display box (pos. 21, SKU 7010543) combined with one of two LED display board variants at pos. 22a or 22b depending on the unit’s configuration. Finally, the pressure gauge at pos. 32 (SKU 7010518) provides a visible indication of system refrigerant pressure and is a common service replacement item.

Choosing between variants and pack sizes

The most important variant choice on this diagram is the LED display at position 22. Position 22a (SKU 7021826, SHHCLEDV2MM101) is the standard inverter display, while position 22b (SKU 7023600, WiFi02iMM011) is the Wi-Fi-enabled inverter display — check which board is fitted in your unit before ordering, as the two are not interchangeable. For the low-pressure switches at positions 53 e 54, the pressure ranges differ (0.1–0.3 MPa versus 0.2–0.35 MPa), and fitting an incorrectly rated switch may cause nuisance trips or inadequate circuit protection, so always confirm the rating marked on the original component. The fan blade at position 16 is specified with a 12 mm bore and anticlockwise rotation; a blade with the correct diameter but the wrong bore size or rotation direction will either not fit the motor shaft or will move air in the wrong direction, reducing efficiency. Where rubber sealing rings are involved — such as the blue rubber ring (pos. 59) and red rubber ring (pos. 66) at the water connections, or the exchanger connection sealing ring (pos. 60) — always replace these whenever a joint is disturbed, as reusing a compressed ring is a common source of water leaks.
