Flotide/MEGA Heat Pump, Type Inverter (Type Xp12Csie) exploded view & spare parts

Flotide/MEGA Heat Pump Inverter (Type Xp12Csie) exploded view & spare parts

This page covers the complete exploded-view diagram and bill of materials for the Flotide/MEGA Heat Pump, Type Inverter, model designation Xp12Csie, supplied under factory reference 7021087. The diagram breaks the unit down into every numbered component — from the outer casing panels and fan assembly through to the refrigerant circuit, electrical box, and water connections — so you can pinpoint exactly what has failed or worn. Whether you are a pool owner carrying out routine maintenance or a technician diagnosing a fault, working through the numbered positions in the diagram will get you to the correct part and SKU within minutes.

Hogyan lehet a számozott ábra segítségével megtalálni az alkatrészt?

Every call-out number printed on the exploded-view diagram corresponds directly to a numbered row in the parts list below the diagram. Start by identifying the general area of the unit where the problem lies — for example, the fan section at the top, the refrigerant pipework in the centre, or the water-connection block at the side — then locate the relevant call-out number within that area on the diagram. Once you have the position number, find the matching row in the parts list to confirm the description and, where available, the SKU for ordering. Bear in mind that the same position number can sometimes appear in more than one location on the diagram; this is common with fasteners, clips, sealing rings, and other small hardware that are used at multiple points across the assembly. On this particular unit, positions 41 and 44 are both listed as “Water connection set” (SKU 7014153), and positions 37 and 48 are both listed as “Water out temperature sensor TH5 plug (6×4)” (SKU 7020262) — confirm the location on the diagram before ordering to ensure you are replacing the correct instance. Pay close attention to lettered variants such as 32a and 32b, which denote distinct parts that share a position group but are not interchangeable. If a position in the parts list shows no SKU, the component is not currently sold individually; contact us and we can advise on availability or suitable options.

Main replaceable assemblies on the Flotide/MEGA Xp12Csie Inverter

The fan assembly groups together position 14 (Fan motor YDK-90-6-2 90W, SKU 7021840), position 15 (Fan blade 490 mm × 125 mm with a 12 mm clockwise-rotation bore, SKU 7010540), and position 13 (Fan motor bracket), all of which work together to draw air across the evaporator coil. The refrigerant circuit is the heart of the heat pump and includes position 21 (Compressor), position 63 (4-way valve, which switches the unit between heating and any defrost or cooling mode), position 61 (Electronic expansion valve), position 22 (Liquid reservoir), and position 46 (Titanium heat exchanger, through which pool water absorbs heat from the refrigerant). Refrigerant-circuit health is monitored by position 27 (Pressure gauge, SKU 7010518), position 53 (High pressure switch 3.6–4.2 MPa, SKU 7024793), and either position 56 (Low pressure switch 0.1–0.3 MPa, SKU 7024791) or position 57 (Low pressure switch 0.2–0.35 MPa, SKU 7024792) depending on the specific build variant of the machine. The compressor is protected against cold-start damage by position 23 (Compressor heating belt 230 V 35 W 390 mm, SKU 7020268), a crankcase heater that keeps the refrigerant oil warm during periods of inactivity. Water temperature management is handled by the sensor pair at positions 37/48 (Water out temperature sensor TH5 plug 6×4, SKU 7020262) and position 39 (Water in temperature sensor TH6 plug 6×4, SKU 7020263), together with position 52 (Exhaust temperature sensor TH3 plug 6×4, SKU 7020261) on the discharge side of the compressor. The water-side connections are served by positions 41 and 44 (Water connection set, SKU 7014153) along with the associated sealing rings at positions 42, 43, and 45. The electrical and control section centres on position 67 (PC Board SH0150101-V1.5, SKU 7021834), housed inside the electric box (position 68) behind the electric box cover (position 65), with the user interface presented via the waterproof display box at position 31 (SKU 7010543).

Choosing between variants and pack sizes

Position 32 on this unit splits into two lettered variants — 32a and 32b — that are not interchangeable. Position 32a is the LED display board for the standard Inverter control system (SHHCLEDV2MM101, SKU 7021826), while position 32b is the Controller display with integrated WiFi (SKU 7023600); you must confirm which display type your unit was originally supplied with before ordering. Similarly, positions 56 and 57 are both low pressure switches but are rated to different pressure ranges (0.1–0.3 MPa and 0.2–0.35 MPa respectively), so cross-check the rating printed on your existing switch or consult your installation paperwork before selecting one. Where water-connection sealing rings are concerned — positions 42 (blue rubber ring), 43 (O-type sealing ring), and 45 (red rubber ring) — the colour coding indicates their specific location and material; fitting the wrong seal can result in a slow weep that is difficult to trace, so order by position number and confirm the description matches. If you are unsure which variant applies to your specific unit, quote the parent factory reference 7021087 when contacting us and we will confirm the correct part before you order.
