Norsup Heat Pump, Type Inverter (Type Xp35Dcsi) exploded view & spare parts

This page provides the full exploded-view diagram and numbered bill of materials (BOM) for the Norsup Heat Pump, Type Inverter — Type Xp35Dcsi, sold under Norsup factory reference 7021082. Reference 7021082 identifies the Norsup ABS 230 V Inverter type 35 horizontal heat pump, a unit capable of a heating capacity range of 35–8 kW at standard rating conditions. The full inverter design adjusts fan speed from 10 % to 100 % depending on outside air and water temperature, significantly reducing energy consumption and noise levels. Whether you are a pool owner replacing a sensor or a technician sourcing a refrigeration component, the diagram and BOM below will help you confirm the correct part in minutes.

How to use the numbered diagram to find your part

Every call-out number printed on the exploded-view diagram corresponds directly to a row in the parts list beneath it — locate the area of the unit where the fault lies, find the nearest call-out number, then read across to the description and SKU column. Once you have the SKU, use it in the search box at the top of the page to go straight to the product listing. Bear in mind that some numbers appear more than once on the diagram: where a fastener, seal, or bracket is used in several locations, Norsup assigns the same position number to each instance, so seeing that number in two or three places is normal. Watch also for lettered variants within a single position — position 22, for example, splits into 22a and 22b, each representing a different LED display module; these are not interchangeable, so you must confirm which variant is fitted before ordering. If a position row in the table shows no SKU, the part is either only supplied as part of a larger assembly or is not currently available to order individually; contact us if you are unsure. Finally, always cross-reference the written description against what you can see on the unit — dimensions, connector sizes, and rated values are included in many descriptions precisely to serve as a second check.

Main replaceable assemblies on the Norsup Heat Pump, Type Inverter (Type Xp35Dcsi)

The air-movement section sits at the top of the unit and centres on the fan motor at position 15 (ZWB378D02B, 120 W, SKU 7021812) together with the fan blade at position 16 (496 mm × 150 mm, 12 mm bore, anti-clockwise rotation, SKU 7021815); both items are among the most commonly replaced wear parts on this model. The refrigeration circuit runs through the compressor (pos. 26), the four-way reversing valve (pos. 50), the electronic expansion valve or EEV (pos. 44), the filter (pos. 43), and the fluid reservoir (pos. 27), with the various interconnecting pipe sections (pos. 45, 46, 47, 52, 55, 56, 57) completing the sealed loop. A titanium heat exchanger is used in Norsup heat pumps for durability and reliability; on this unit it appears at position 67 (SKU 7021833), with its water-side connections sealed by the exchanger connection sealing ring (pos. 60) and the water connection sets at positions 58 and 65 (both SKU 7014153). Refrigerant-side protection is provided by the high-pressure switch at position 49 (3.6–4.2 MPa, SKU 7024793) and two low-pressure switch variants at positions 53 and 54 (SKUs 7024791 and 7024792 respectively). The water-side sensing group includes the water flow switch at position 61 (VH-2, SKU 7020257), the water inlet temperature sensor TH6 at position 63 (SKU 7020263), the water outlet temperature sensor TH5 at position 68 (SKU 7020262), and the exhaust temperature sensor TH3 at position 48 (SKU 7020261). The electrical enclosure (pos. 78) houses the PC board SHZKA0101 (pos. 76, SKU 7021837), the driver board SHQ050101 (pos. 71, SKU 7021838), the relay CJX9B-25S/D 220–240 V AC (pos. 75, SKU 7010519), the pressure gauge (pos. 32, SKU 7010518), and the filter board (pos. 74). The user interface is built around the waterproof display box at position 21 (SKU 7010543) and one of the two LED display modules at position 22.

Choosing between variants and pack sizes

The most important variant decision on this diagram is at position 22, where the BOM lists two mutually exclusive LED display modules: 22a is the standard inverter display (SHHCLEDV2MM101, SKU 7021826) and 22b is the Wi-Fi-enabled version (WiFi02iMM011, SKU 7023600). The display is how you set temperatures and programmes, view consumption and temperature history, and — with the Wi-Fi variant — control the heat pump remotely from a smartphone or tablet; fitting the wrong module will leave those functions unavailable or entirely non-functional. Similarly, positions 53 and 54 list two low-pressure switches with different rated ranges (0.1–0.3 MPa and 0.2–0.35 MPa respectively); the pressure rating is stamped on the original switch body, and ordering the wrong range will affect the unit’s safety cut-out behaviour. Likewise, the two water connection sets at positions 58 and 65 share the same SKU (7014153), confirming they are identical items used at different points in the plumbing — if you need both, order two units. Where a position description includes a precise physical dimension — such as the fan blade diameter and bore at position 16, or the connector pin-out on the sensor plugs at positions 48, 61, 63, and 68 — use those measurements to verify against the original part before checkout, as substituting an incorrect size can result in fitting damage or inaccurate readings.
