Not a like-for-like — capacity step-down

Your T622226G150 is rated 23,500 BTU/hr at 230V. VoltAire doesn't build a 230V unit at that capacity. The closest 230V option, the AT19RNW20, is 19,000 BTU/hr (about −19% cooling). If you can find a 230V 23,500 BTU/hr unit elsewhere, that's the true like-for-like — if you can't, this one fits with the adapter plate and runs on your voltage.

Adapter Fit

Same 230V supply as your T622226G150 — but 19,000 BTU/hr vs your 23,500 BTU/hr (see the capacity note above). Cabinet cutout dimensions differ, so an adapter plate is required to bridge the mounting pattern between the existing opening and the VoltAire AT19RNW20 — so you're not fabricating a new opening. Plan on some fitting work during the swap; we'll spec the exact adapter for your installation at order review.

Existing nVent unit VoltAire replacement

T6222 to AT19 Adapter plate + provisional cabinet cuts

Plan on the adapter plate plus some cabinet cutting — the red areas show where the new openings reach beyond the existing cutout. The red areas come from the manufacturer's spec sheet and must be confirmed against your actual unit before cutting.

Existing nVent AC outline Existing nVent opening Existing service/access opening Adapter plate New VoltAire unit outline Stamped VoltAire opening Existing cabinet metal that may need removal — verify first

The red hatching shows cabinet metal outside the existing openings; verify it against your actual unit before cutting.

Step 1 of 4 Start with the existing T6222 cabinet pattern.

The green adapter plate covers the existing pattern and contains the VoltAire stamped openings; use the supplied plate for final dimensions, holes, gaskets, and cut locations. The two manufacturer drawings are centered on each other for visual comparison only, because a shared mounting reference between the two units has not been verified. Verify every opening against your actual unit before any cutting or mounting. The AT19 cutout starts 1.84 inches from the top and ends at 42.62 inches, leaving 10.41 inches of cabinet below the opening. The separate 8.57-inch lower drawing section is not part of the airflow cutout. This comparison is a visual guide, not a cutting or drilling template. Openings can vary with voltage and production run — verify against your actual unit before any cutting or mounting, and follow the manufacturer's installation template.

T622226G150 Replacement — Common Questions

What replaces the McLean T622226G150?

The VoltAire AT19RNW20 — 19,000 BTU/hr at 230V, NEMA 4, UL/cUL Listed and built in Orlando, FL. Adapter fit — mounts to your existing cutout with the included adapter plate. Note: this is a capacity step-down — 19,000 BTU/hr vs your unit's 23,500 BTU/hr — the closest 230V option VoltAire builds; the difference is spelled out in numbers on this page.

Is the T622226G150 discontinued?

Yes. nVent has discontinued the T622226G150. The VoltAire AT19RNW20 is an in-production replacement at the same voltage and in the same capacity class, backed by a 12-month warranty.

Will the VoltAire AT19RNW20 fit my T622226G150 cutout?

Yes, with the adapter plate included in the quoted total. It bridges your existing T622226G150 cutout to the AT19RNW20 mounting pattern so you're not fabricating a new opening — but plan on some fitting work during the swap. The dimensions table on this page compares both units side by side; if anything looks off for your cabinet, call (844) 925-5668 before you order.

How much does a T622226G150 replacement cost?
