Gree OWC18HP230V1R32AH One Way Ceiling Cassette Indoor Unit 18000 Btu/h R32 230V Mini Split Air Handler

Product Description

The GREE OWC18HP230V1R32AH is an 18,000 BTU/h one-way ceiling cassette indoor unit designed for ductless mini-split systems operating on R32 refrigerant at 230 volts. This unit delivers directional airflow through a single discharge louver with swing louver control, making it well suited for narrow or elongated spaces where targeted conditioning is required. An internal condensate drain pump with a sentry float switch manages moisture removal without requiring a gravity drain. DC inverter-driven operation and copper tube and aluminum fin coil construction are standard. Licensed HVAC technicians install this unit as part of a complete mini-split system paired with a compatible outdoor unit.

The OWC18HP230V1R32AH is designed for residential and light commercial applications where ceiling-mounted, concealed air distribution is preferred. It is compatible with GREE Multi21 R32 multi-zone outdoor units and GREE All Match single-zone outdoor units. The unit is rated under AHRI Certificate 215417456 (Vireo R32), 215417449 (Envo R32), and 215416022 (Sapphire R32), confirming performance validation across multiple matched system configurations. Typical installs include offices, retail corridors, hotel rooms, and residential spaces with finished ceilings.

Compatibility

Compatible with GREE Multi21 R32 multi-zone outdoor units and GREE All Match single-zone outdoor units. AHRI-certified performance is validated under certificate numbers 215417456, 215417449, and 215416022 for matched Vireo R32, Envo R32, and Sapphire R32 system configurations respectively.

Installation Notes

Installation must be performed by a licensed HVAC technician holding an EPA Section 608 certification, as this system uses R32 refrigerant, which is classified as mildly flammable (A2L). Power to the indoor and outdoor units must be disconnected at the breaker before any service work begins. Ceiling structural support must be verified before mounting the cassette chassis, and all refrigerant line connections, electrical wiring, and condensate drain must be confirmed per local mechanical and electrical codes before commissioning.
