Amana Introduces ALXS4N and ALXS4B R32 Condensers

Amana Introduces ALXS4N and ALXS4B R32 Condensers

Amana is introducing new R32 14.3 SEER2 condensers to replace the existing R410A condensers. The old ASXN4 will transition to the new ALXS4N and the old ASXH4 will transition to the new ALXS4B.

Background:

• This change is a part of the transition to A2L refrigerants.
• Daikin is getting a head start on the transition to prepare for the installation cutoff at the end of 2025.

Changes to Note:

• There is a one-to-one model change, as shown on the right.
• The new units use R32 and will require R32 coils and air handlers to match.
• When matched to a non-UL2-40 furnace, Furnace Integration Kit 0230K00044 (.489914) is required.
• R32 equipment uses significantly less charge than R410A.
• The condensers have been upgraded in some aspects to conform to UL Standard 60335-2-40 (aka UL2-40).
  • Contactors are enclosed, with lug connections.
  • The grille top is now compliant.
• In some cases the units are smaller. See Appendix Two.

Additional Items to Note:

• DO NOT mix R32 and R410A equipment to make a system.
• R32 equipment uses a much smaller charge. Remember to check the IOM.
• Sign up to receive your R32 certification! It is not required, but is best practice.
• Have the proper tools to work with R32 and R454B equipment.

Transition

HVAC Distributors will continue to stock the old models, then transition to the new models when inventory is depleted.
