Coleman‑Mach 46515‑611 2‑Ton Basement AC/Heat Pump — OEM Replacement for 46515‑811 The Coleman‑Mach 46515‑611 is the current OEM 2‑Ton basement‑mounted packaged AC/Heat Pump used in premium RVs and motorhomes. This dual‑compressor system delivers high‑efficiency cooling and full‑capacity heat pump operation while keeping noise and condensate off the roof. The 46515‑611 directly replaces the discontinued 46515‑811 and uses the same service parts, electrical components, and coil assemblies. Ideal for large RVs requiring maximum climate control performance in a compact under‑floor package.
