This page provides the official exploded-view diagram and full bill of materials for the Hydro-Pro Heat Pump (Type 5), carried under Hydro-Pro factory reference 7018522<\/strong>. The diagram covers the complete unit \u2014 from the air-side components (evaporator, fan, and grilles) through to the refrigerant circuit and the water-side plumbing connections. Whether you are a pool owner tracing a fault or a technician ordering a replacement part, every numbered call-out on the drawing maps directly to a row in the parts list below, so you can confirm the correct SKU in minutes.<\/p>\n Start by locating the area of the unit where the fault or wear is visible \u2014 for example, the electrical enclosure, the fan assembly, or the water connections \u2014 then find the corresponding call-out number on the diagram. Each number in the diagram matches exactly one row in the parts table, giving you the part description and, where available, the poolparthub.com SKU to add directly to your basket. Pay close attention to lettered suffixes: position 3, for instance, is split into 3a (ambient temperature sensor T5), 3b (water-in sensor T1), 3c (water-out sensor T2), and 3d (pipe sensor T3) \u2014 four physically different sensors sharing the same position group. Similarly, position 15 splits into 15a (the standard XK 001 V1 display) and 15b (the Wi-Fi enabled WiFi02i display); fitting the wrong variant will result in an incompatible control board connection. Some positions \u2014 such as structural panels, pipework, and rubber seals \u2014 appear in the diagram for reference but are listed without a direct SKU, meaning they are either non-serviceable as individual items or must be sourced as part of a sub-assembly. If a position shows no SKU, contact our team before ordering.<\/p>\n Il temperature sensor group<\/strong> (positions 3a\u20133d) is one of the most frequently replaced sections of this heat pump. The four sensors monitor ambient air, water-in, water-out, and refrigerant pipe temperatures respectively, and each has its own SKU to ensure an exact match. The gruppo ventola<\/strong> comprises the fan motor at position 11 (YDK-25-6, 25 W) and the 400 mm × 118 mm fan blade at position 12 (8 mm shaft hole, anticlockwise rotation) \u2014 both are individually available and should always be inspected together when diagnosing poor airflow or excessive noise. The sezione di controllo e visualizzazione<\/strong> includes the PC board at position 23 (ZK 101 V1, SKU 7010513), the transformer at position 19 (ZHL-03\/EL-48, SKU 7010532), and the LED display panel at position 15a or 15b depending on whether the unit was supplied with standard or Wi-Fi control. Two capacitors<\/strong> serve different functions within the electrical box: the 25 \u00b5F round wired type at position 20 (SKU 7010427) and the 2 \u00b5F square plugged type at position 22 (SKU 7010416) \u2014 confirm which is faulty before ordering, as they are not interchangeable. The circuito del refrigerante<\/strong> is anchored by the titanium heat exchanger at position 37 (SKU 7020783), which transfers heat to the pool water and is resistant to chlorine and salt water; the high-pressure switch at position 30 (3.6\u20134.2 MPa, SKU 7024793) and the low-pressure switch at position 28 (0.1\u20130.3 MPa, SKU 7024791) protect the circuit from over- or under-pressure conditions. On the water side, the flow switch<\/strong> at position 44 (32 mm glue adapter, SKU 7006471) prevents the unit from running without adequate water flow, and the set di allacciamento idraulico<\/strong> at position 48 (50 mm glue socket, SKU 7014127) provides the primary plumbing interface to the pool pipework. The pressure gauge<\/strong> at position 39 (SKU 7010518) and the terminal block<\/strong> at position 42 (220\u2013240 V, 32 A \/ 16 mm\u00b2, SKU 7010527) round out the individually stocked serviceable parts.<\/p>\n The most important variant decision on this unit is the display panel<\/strong> at position 15. Position 15a (SKU 7010515) is the standard LED On\/Off panel referenced as XK 001 V1 MM011, while position 15b (SKU 7023601) is the Wi-Fi enabled version referenced as WiFi02i MM101. These two panels use different communication protocols with the PC board at position 23, so you must match the replacement to whichever display variant was fitted at the factory. For the capacitors<\/strong>, the two types differ in capacitance, physical format, and connection method \u2014 the 25 \u00b5F unit (pos. 20) uses a round wired format, whereas the 2 \u00b5F unit (pos. 22) is square and plugged; mixing them up will prevent the motor or compressor circuit from starting correctly. When ordering the PP plug<\/strong> at position 38 (\u00bd" male thread, 10 bar, SKU 0121241), confirm the thread pitch and material are compatible with your existing plumbing fittings before installation. For any position where lettered sub-variants exist, always cross-reference both the position number and the full part description against the label or data plate on your unit, as the Type 5 designation covers a single configuration but the lettered suffixes reflect real physical differences that affect fitment.<\/p>","protected":false},"excerpt":{"rendered":"Come utilizzare lo schema numerato per individuare il proprio componente<\/h3>\n
