Fits after modification — plan for sheet-metal work

Your CR290426G061 has a replacement — with one honest catch.

Same 4,000 BTU/hr, same 230V. The mounting holes and air cutouts need adjusting to take the AT04RQSXX — routine sheet-metal work from our swap template, so the gasket seats properly.

Fits After Modification

Same cooling capacity and voltage as the CR290426G061 — a solid match, just not bolt-for-bolt. Both the mounting pattern and the air cutouts need adjusting to take the VoltAire AT04RQSXX — routine sheet-metal work on a metal cabinet, no adapter plate required. VoltAire suggests working from the swap template so the mounting holes land right and the gasket seats with proper compression — that's what keeps water out. Call (844) 925-5668 if you'd like us to walk through it before you order.
