The HVAC Mirage CGFH121C GALAXY Series is a high-performance 12,000 BTU Traditional 4-Way Ceiling Cassette indoor air handler. Designed for discreet, flush-mount installation in suspended or drywall ceilings, it delivers quiet, multi-directional airflow for single or multi-zone systems.
Engineered for professional integration, this 208/230V cassette unit seamlessly distributes conditioned air across 360 degrees, eliminating hot and cold spots. The unit requires 14/4 AWG stranded communication wire and must be matched with a compatible HVAC Mirage outdoor condenser to form an operational system.

Pro-Installer Tip
Field Note: When installing Traditional 4-Way Ceiling Cassettes, leaking flare connections are a common point of failure for Non-DIY systems. Always use a Digital Torque Wrench to tighten the 3/8" and 7/8" flares to HVAC Mirage factory specifications. This prevents refrigerant loss and E1 communication codes. Furthermore, per EPA Section 608 mandates, the system must hold a vacuum below 500 microns for 15 minutes before opening service valves to ensure long-term efficiency with the R-454B low-GWP refrigerant.

FAQ
Is professional installation required to keep the warranty valid, or is this a true DIY kit?
This is not a DIY kit. Professional installation is required to validate the 7-Year Compressor / 5-Year Parts Limited Warranty, which includes pulling a vacuum below 500 microns and correctly torquing flare connections.
Is the line set included, and if not, what size do I need to buy?
A line set is NOT included. You will need a standard flared line set with 3/8" Liquid and 7/8" Suction connections.
Compliance & Warranty
This component is backed by a 7-Year Compressor / 5-Year Parts Limited Warranty when installed by a licensed professional. It is fully compliant with the 2026 mandate for low-GWP refrigerants (R-454B).
