Gree SAP18HP230V1R32AH Sapphire Single Zone Wall Mount Mini Split Air Handler 18000 Btu/h R32 230V

Product Description

The GREE SAP18HP230V1R32AH is a single-zone wall-mount indoor air handler from the Sapphire R32 series, designed for use in ductless mini split heat pump systems. Rated at 18,000 BTU/h for both cooling and heating, it operates on 230 volts and uses R32 refrigerant, a lower-GWP alternative to R410A. High-efficiency DC inverter technology allows the system to modulate output to match load conditions, reducing energy consumption compared to fixed-speed units. The unit ships with Wi-Fi capability factory installed and supports a wired controller interface. Licensed HVAC technicians handle installation and commissioning of this equipment.

This air handler is suited for residential and light commercial single-zone applications where a wall-mount evaporator is preferred. The wide operating range supports cooling down to -20 degrees F and heating down to -22 degrees F, making it a strong candidate for northern climates with cold winters. The Sapphire series targets spaces that demand quiet, precise temperature control with minimal footprint. A 7-speed crossflow indoor fan delivers airflow flexibility across different room configurations.

Key Features

• 18,000 BTU/h cooling and heating capacity at 230 volts
• R32 refrigerant with DC inverter compressor technology for variable-speed operation
• Cooling operating range: -20 degrees F to 122 degrees F; heating operating range: -22 degrees F to 86 degrees F
• Wi-Fi included factory installed; wired controller interface also supported
• 7-speed crossflow indoor fan with auto-clean function
• Indoor coil: copper tube and aluminum fin with anti-corrosion coating (blue fin, 50-hour salt spray rated); outdoor coil: copper tube and aluminum fin with gold anti-corrosion coating (1,500-hour salt spray rated)

Compatibility

The SAP18HP230V1R32AH is the indoor air handler component of the GREE Sapphire R32 single-zone mini split system. It is designed to pair with the corresponding GREE Sapphire R32 outdoor unit (SAP18HP230V1R32AO) as a matched set. It may also be compatible with select GREE multi-zone outdoor units; verify outdoor unit compatibility with GREE documentation before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician holding the appropriate EPA Section 608 certification for handling R32 refrigerant. Power must be disconnected at the breaker before any electrical work, and refrigerant lines must be leak-tested and evacuated to proper micron levels before charging. Wall penetration, line set routing, and electrical connections should comply with local mechanical and electrical codes. Do not operate the system without verifying refrigerant charge and confirming all electrical connections are secure.
