This page provides the official exploded-view diagram and full bill of materials for the Hydro-Pro Heat Pump Type 26T (factory reference 7018530), the largest model in the Hydro-Pro P-series range. The 26T is a three-phase unit, designed for larger pool installations. The Hydro-Pro P-series comes in black ABS casing, with a titanium heat exchanger that provides protection from chlorine, bromine, salt, and all natural outdoor elements. The diagram covers every major sub-assembly \u2014 from the control electronics and water circuit to the refrigerant circuit and enclosure panels \u2014 so you should be able to identify the numbered part you need within minutes.<\/p>\n
Every numbered call-out on the diagram corresponds directly to a row in the parts list below it; locate the area of the unit where your worn or damaged component sits, then find the matching position number in the diagram. Once you have the position number, look across the same row in the table to find the part description and, where stocked, the SKU you will enter at checkout. Bear in mind that some position numbers carry a letter suffix \u2014 positions 10a, 10b, and 10c denote three distinct display variants sharing the same physical mounting location, while positions 54a and 54b denote the low-pressure and high-pressure switches respectively; ordering the wrong lettered variant will result in an incompatible part. Where a position number appears in more than one location on the diagram (for example, rubber seals at positions 12 and 17, or water connection sets at positions 11 and 16), the diagram is calling out an identical or related part used in multiple spots \u2014 always count how many you require before adding to your basket. Some positions in the BOM do not yet carry a SKU; these are structural or refrigerant-circuit components not currently sold individually. If the SKU field for your position is blank, please use the contact form to enquire about availability before ordering a substitute.<\/p>\n
The Type 26T divides naturally into four service areas. The control and display group<\/strong> centres on position 39 (PC Board ZK 101 V1, SKU 7010514), which governs all operating logic, together with the display panel at position 10a (LED display On\/Off XK 001 V1 MM011, SKU 7010515) or the WiFi-enabled alternative at 10b (SKU 7023601). Supporting electronics in the electric box include the transformer at position 40 (SKU 7010532), the capacitor at position 41 (SKU 7019180), the terminal block at position 46 rated at 380\u2013400 V \/ 16 A (SKU 7010526), and the phase sequence relay at position 51 (SKU 7017965), which is a critical protection component on this three-phase model. The water circuit<\/strong> runs through the titanium heat exchanger at position 18 (SKU 7020789), a titanium unit that resists corrosion from pool chemicals and is oversized to maximise thermal efficiency. Water enters and exits through the 50 mm glue-socket connection sets at positions 11 and 16 (both SKU 7014127), and flow is monitored by the water flow switch at position 19 (SKU 7006471) \u2014 an integrated switch that senses water movement and automatically starts the heat pump when the pool pump runs, and stops it when the pool pump shuts off. Pool water temperatures are tracked by three sensors: the water-in sensor T1 at position 23 (SKU 7010534), the water-out sensor T2 at position 21 (SKU 7010535), and the pipe sensor T3 at position 27 (SKU 7010533). Ambient conditions are read by sensor T5 at position 59 (SKU 7010537). The refrigerant circuit<\/strong> includes the 4-way reversing valve (positions 56 and 57), the electronic expansion valve at position 34, and pressure protection via the low-pressure switch at position 54a (SKU 7024791) and the high-pressure switch at position 54b (SKU 7024793). Finally, the enclosure<\/strong> comprises the left side panel (25), front panel (26), maintenance covers (28 and 29), electric box cover (48), and the base tray (13), none of which are currently listed with individual SKUs.<\/p>\n Position 10 offers three distinct variants \u2014 10a, 10b, and 10c \u2014 and it is essential to identify which display your unit was supplied with before ordering. Position 10a (SKU 7010515) is the standard wired LED panel (model reference XK 001 V1 MM011), while position 10b (SKU 7023601) is the WiFi-enabled model (WiFi02iMM101); the two are not interchangeable because they use different communication protocols with the PC board at position 39. Position 10c (the waterproof box) has no SKU and is therefore not available to order individually at this time. Similarly, positions 54a and 54b are both pressure switches but operate at entirely different pressure ranges \u2014 0.1\u20130.3 MPa for the low-pressure switch (54a, SKU 7024791) and 3.6\u20134.2 MPa for the high-pressure switch (54b, SKU 7024793) \u2014 and fitting the wrong one will compromise the safety protection of the unit. Where the same SKU appears at two positions (such as SKU 7014127 at both position 11 and position 16), check the diagram carefully to establish how many pieces you need, as the connection set is used on both the inlet and outlet sides of the water circuit.<\/p>","protected":false},"excerpt":{"rendered":"Choosing between variants and pack sizes<\/h3>\n
