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

This page contains the full exploded-view diagram and numbered bill of materials (BOM) for the Norsup Heat Pump, Type Inverter, model designation XP26DCSI T, listed under Norsup factory reference 7021081. The unit is a 230 V / 50 Hz single-phase, horizontal-format full-inverter pool heat pump in the 26 kW output class, designed to vary its heating capacity automatically to suit ambient conditions. Every component shown in the diagram — from the outer cabinet panels and fan assembly right through to the refrigerant circuit and electronic control boards — is represented in the parts list below. Whether you are a pool technician carrying out a scheduled service or a pool owner sourcing a replacement part, working through this page should allow you to identify exactly what you need in a matter of minutes.

Come utilizzare lo schema numerato per individuare il proprio componente

Every numbered call-out bubble in the exploded-view diagram corresponds directly to a position number (the “pos” column) in the parts list table beneath it. The most efficient approach is to locate the general area of the unit where the fault or wear has occurred — for example, the fan and airside assembly at the top of the cabinet, the refrigerant circuit components around the compressor, or the waterside connections at the rear — then identify the call-out number in that area of the diagram. Once you have the position number, find the matching row in the BOM and note the SKU; that SKU is what you add to your basket. Be aware that some position numbers appear on the diagram in more than one location: positions 58 and 65, for example, both refer to the same water connection set (SKU 7014153) and share a single SKU precisely because they are identical parts used at the water inlet and outlet respectively. Similarly, positions 53 and 54 are both low-pressure switches but carry different pressure ratings and different SKUs, so confirming the exact specification before ordering is essential. Pay close attention to lettered suffixes in the position column: position 22a and position 22b look nearly identical on the diagram but represent two different LED display boards for different connectivity variants of the same unit. Where a position number has no SKU shown, the part is not currently available individually and you are advised to contact us for guidance before ordering. Always cross-reference the written part description in the BOM against the physical component you are replacing to be certain of a match.

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

Il fan assembly sits at the top of the cabinet and consists of the fan motor bracket (pos. 14), the fan motor ZWB378D02B rated at 120 W (pos. 15, SKU 7021812), and the 496 mm fan blade with a 12 mm anticlockwise bore (pos. 16, SKU 7021815); the motor and blade are the two components most commonly requested after impact damage or bearing failure. Below the fan, the outer cabinet is made up of individual panels — top frame (pos. 12), left side panel (pos. 17), front panel (pos. 19), front grill (pos. 20), right panel (pos. 38), back panel (pos. 41), and base tray (pos. 25) — along with the isolation panel (pos. 10) and pillars (pos. 13) that give the structure its rigidity. The control and display assembly centres on the waterproof display box (pos. 21, SKU 7010543) and the LED display board at position 22 (see variants below), supported by the wiring box (pos. 18), the electric box (pos. 79), and its cover (pos. 70). Inside the electric box, the driver board SHQ05T0101 (pos. 71, SKU 7021839), PC board SHZKA0101 (pos. 77, SKU 7021837), filter board (pos. 75), and relay CJX9B-25S/D 220–240 V AC (pos. 76, SKU 7010519) form the core inverter electronics. The refrigerant circuit includes the compressor (pos. 26) with its damping feet (pos. 29) and heating belt (pos. 28), the 4-way valve (pos. 50) and its associated pipework (pos. 47, 56), the electronic expansion valve — EEV (pos. 44) — the fluid reservoir (pos. 27), the refrigerant filter (pos. 43), and the exhaust pipe (pos. 52). Refrigerant-circuit safety is managed by the high-pressure switch rated 3.6–4.2 MPa (pos. 49, SKU 7024793), and by two low-pressure switch variants at positions 53 (SKU 7024791) and 54 (SKU 7024792) covering different set-point ranges; the exhaust temperature sensor TH3 (pos. 48, SKU 7020261) is also part of this circuit. The waterside assembly revolves around the titanium heat exchanger (pos. 67, SKU 7021832), which connects to the pool plumbing via the water connection sets at positions 58 and 65 (both SKU 7014153) and is protected by the water flow switch VH-2 (pos. 61, SKU 7020257) and its sealing ring (pos. 62). Water temperature is monitored at two points: the water-in sensor TH6 (pos. 63, SKU 7020263) and the water-out sensor TH5 (pos. 68, SKU 7020262), both using a 6×4 mm plug format. The pressure gauge (pos. 32, SKU 7010518) provides a local visual indication of system pressure, while the 1/2-inch male-thread plug (pos. 69, SKU 0121241) serves as the service port cap.

Choosing between variants and pack sizes

The most significant variant choice on this model is the LED display board at position 22. Position 22a (SKU 7021826, model code SHHCLEDV2MM101) is the standard wired inverter display, while position 22b (SKU 7023600, model code WiFi02iMM011) is the Wi-Fi-enabled equivalent that allows the unit to be controlled remotely via an app. Before ordering, check which board is currently fitted by examining the part number printed on the board itself, as the two are not interchangeable. A similarly important distinction applies to the two low-pressure switch variants at positions 53 and 54: despite appearing alike, they operate at different pressure thresholds (0.1–0.3 MPa and 0.2–0.35 MPa respectively), and fitting the incorrect switch will affect cut-out behaviour and may prevent the unit from running safely. The water connection sets at positions 58 and 65 share a single SKU (7014153) and are identical, so one order line covers both positions if you need to replace the pair. For sealing components such as the blue rubber ring (pos. 59), red rubber ring (pos. 66), exchanger connection sealing ring (pos. 60), and flow-switch sealing ring (pos. 62), always confirm the correct diameter against the original before fitting, as a slight size mismatch will result in a water leak at the heat exchanger connections.
