What This Part Does

The transformer kit is item 2 on the JXi / IXI electrical system diagram, with the one part number, R0456301, for both heater sizes.

The heater comes factory-wired for a 230 V, 50 Hz supply, and its wiring diagram (Astralpool IXI manual, Figure 17) shows the transformer feeding the heater's 24 VAC control wiring. The transformer is reached through the default front panel, together with the ignition control, power interface board and voltage selector board.

The Rating Plate Rule (rev. IXJ-1.0)

Identify the part by the heater it came from:

1. Find the rating plate. It is inside the heater, on the outside of the combustion chamber, and shows the model number, serial number and gas type. Zodiac's JXi manual says these are needed to identify the correct part.
2. Check the badge. Astralpool IXI and Zodiac JXi heaters use the same part number for this part, so either badge is fine.
3. Check the size. R0456301 is listed for both the 200 and the 370, so the heater size doesn't change the part.
4. Match the diagram. On the electrical system diagram this part is item 2. The diagrams are on our IXI / JXi parts page.

Worked Example

Say the rating plate on your heater reads Astralpool IXI 370 and you need the transformer kit. The IXI and the JXi share this part, and R0456301 covers both the 200 and the 370, so R0456301 is the part to order. A Zodiac JXi 200 takes the same R0456301.

Fitting Notes From the Manual

A summary for the qualified technician doing the job. It does not replace the manufacturer's manual.

1. Electrical work must be done by a licensed electrician. Turn off all power to the heater at the breaker before starting.
2. Access is through the heater's front panel: remove its four screws to expose the electrical raceway, which releases and swings free for service.
3. Label all wires before disconnecting them. The manual warns that wiring errors can cause improper and dangerous operation.
4. Verify proper operation after servicing. Don't use the heater if any part of its control system has been under water; have a qualified service technician inspect it and replace any affected part.
