Flotide/MEGA Heat Pump (Type 5) exploded view & spare parts

Flotide/MEGA Heat Pump (Type 5) exploded view & spare parts

This page provides the full exploded-view diagram and numbered bill of materials for the Flotide/MEGA Heat Pump Type 5, sold under factory reference 7018518. The Flotide/MEGA range is manufactured to serve above-ground and domestic pools, using an air-source refrigeration cycle to transfer heat efficiently into pool water. Every component shown in the diagram — from the fan assembly and electrical enclosure through to the refrigerant circuit and water connections — is mapped to a numbered position in the parts list below. Whether you are a pool owner carrying out routine maintenance or a technician diagnosing a fault, you should be able to identify the exact part you need within a few minutes.

Cómo utilizar el esquema numerado para localizar tu pieza

Start by locating the area of the unit where the fault or wear has occurred — for example, the electrical box, the refrigerant circuit, or the water connections — then scan that area of the diagram for the relevant call-out number. Each number on the diagram corresponds directly to a numbered row in the parts list, where you will find the part description and, where available, the SKU you need to add to your basket. Note that position 4 is split into lettered variants — 4a, 4b, 4c, and 4d — each representing a different temperature sensor (T1 through T4), so always confirm which sensor location is faulty before ordering. Similarly, take care when a position number appears in more than one place on the diagram, which can happen with common hardware items such as clips (position 22) or wiring clips (position 25). Where a part in the list has no SKU shown, it is either a structural panel, a formed pipe, or another non-serviceable component that is not stocked as a standalone spare. If you are unsure whether a part carries a separate SKU, use the site search with the position description or contact our team before ordering.

Main replaceable assemblies on the Flotide/MEGA Heat Pump (Type 5)

El air circuit sits at the heart of the unit’s heat-exchange process and comprises the evaporator (position 6), the fan motor (position 12 — a YDK-18-6 18 W unit), and the 320 mm fan blade (position 13, with a 7 mm anticlockwise-pitch bore). The fan motor and blade are the most commonly replaced moving parts on any air-source heat pump, and both carry dedicated SKUs on this diagram. The refrigerant circuit includes the compressor (position 33), the electronic expansion valve (position 31), the high-pressure switch rated 3.6–4.2 MPa (position 27), and the low-pressure switch rated 0.1–0.3 MPa (position 30); the two pressure switches are stocked as spares and are frequently the first components to flag a refrigerant-side fault. A single pressure gauge (position 36) provides a visual reference point for circuit pressure. The electrical enclosure (positions 17–25) houses the PC board Flotide/MEGA ZK 101 V13 (position 23), the transformer ZHL-03/EL-48 (position 19), a 2 µF square plug-in capacitor (position 18) for the fan motor, and a 25 µF round wired capacitor (position 21) typically associated with the compressor start circuit; all four of these electrical components carry SKUs. Two terminal blocks are fitted: position 24 for 220–240 V 16 A supply and position 34 for 380–400 V 16 A supply, reflecting the dual-voltage configurations in the Type 5 family. The water circuit connects to the pool via the water connection set 50 mm compression (position 38), a water flow switch with glued 32 mm adapter (position 42), and the heat exchanger (position 37). The user interface is provided by the LED display Flotide/MEGA XK 302 V1 (position 45), which is a stocked spare part.

Choosing between variants and pack sizes

The four temperature sensors at position 4 — 4a (pipe sensor T3, SKU 7010533), 4b (water-in sensor T1, SKU 7010534), 4c (water-out sensor T2, SKU 7010535), and 4d (back gas sensor T4, SKU 7010536) — are physically similar but are calibrated and positioned for different measurement points within the refrigerant and water circuits; fitting the wrong sensor to a given port will produce erroneous readings and may trigger unnecessary fault codes. Always cross-reference the sensor position label on the wiring loom or PCB terminal before selecting a variant. The two capacitors at positions 18 and 21 are also distinct: the 2 µF square plug-in type (position 18) and the 25 µF round wired type (position 21) are not interchangeable, and substituting one for the other will damage the motor or compressor circuit it serves. Similarly, the two terminal blocks differ by voltage rating — 220–240 V at position 24 and 380–400 V at position 34 — so confirm your supply voltage before ordering. Where parts such as the plug at position 39 (PP ½” male thread, 10 bar black) are specified with thread size and pressure rating, ensure any replacement matches all three parameters, as thread pitch, diameter, and pressure tolerance all affect sealing integrity.
