Zodiac – Evaporator Z400 MD7/TD7 – R0813300

The Zodiac Evaporator Z400 MD7/TD7 (R0813300) is a genuine OEM replacement evaporator unit designed specifically for the Zodiac Z400 heat pump range, compatible with the MD7 and TD7 models. The evaporator is the critical heat-exchange component responsible for extracting thermal energy from the ambient air and transferring it into the refrigerant circuit. It is an essential element of the heat pump’s refrigeration cycle, directly influencing the system’s efficiency and heating capacity.

As a factory-matched spare part, this evaporator ensures full compatibility with the Z400 MD7 and TD7 heat pump units, maintaining the performance standards set by the original equipment. Using a genuine Zodiac replacement component helps preserve the energy efficiency rating and the reliable operation of the heat pump over its service life. This part is intended for installation by a qualified technician, as it forms an integral part of the sealed refrigerant circuit.

Technical characteristics and compatibility

The R0813300 evaporator is engineered to the precise specifications of the Zodiac Z400 MD7 and TD7 heat pump models. The evaporator assembly is constructed to withstand outdoor operating conditions and the thermal stresses associated with continuous heat pump operation. It interfaces directly with the refrigerant circuit and the air-side fan assembly of the Z400 unit. Because the Z400 series heat pumps are designed for residential pool heating, this evaporator is dimensioned to match the thermal capacity requirements of these models. Replacement of this component restores the heat pump to its factory performance specification, including its rated coefficient of performance (COP) and heating output.

Installation requires recovery of the refrigerant charge by a certified HVAC or pool heating technician prior to removal of the existing evaporator, followed by correct reassembly, leak testing, and recharging. This is not a user-serviceable part and should only be fitted by a qualified professional.

Suitability and application

This evaporator is exclusively suited to Zodiac Z400 heat pumps in the MD7 and TD7 configurations. It is the correct replacement part when the existing evaporator shows signs of corrosion, refrigerant leaks, physical damage, or reduced thermal efficiency that cannot be resolved by cleaning or maintenance alone. Pool operators using the Zodiac Z400 MD7 or TD7 for residential outdoor or indoor pool heating will find this genuine replacement part the most reliable route to restoring full system performance. Always verify your Z400 model variant before ordering to ensure correct fitment.
