Bosch bova-36rxb-m15s 3 Ton Heat Pump Inverter 15 SEER2

Product Description

The BOSCH bova-36rxb-m15s is a 3-ton inverter-driven heat pump condensing unit from the BOVA Light Series, rated at 15 SEER2 and designed to operate on R454B refrigerant. The unit uses an inverter-driven rotary compressor with a modulation range of 33% to 128% speed in 1% increments, allowing the system to match load demand closely and reduce short-cycling. Rated for 208-230/1/60 electrical service, this condensing unit is sized for residential and light-commercial split-system applications. HVAC technicians install and commission this unit as the outdoor component of a matched split system.

The bova-36rxb-m15s is intended for residential and light-commercial split-system heat pump installations where inverter-modulated capacity control is required. It is designed around R454B, a lower-GWP A2L refrigerant, which means installation must follow applicable local codes and equipment-manufacturer guidelines for A2L refrigerant handling. The unit is AHRI certified and ETL listed, making it suitable for permitted installations in jurisdictions that recognize those certifications.

Key Features

• Inverter-driven rotary compressor with 33% to 128% speed range, modulating in 1% increments
• Intelligent Oil Return Technology for compressor longevity during variable-speed operation
• Crankcase heater and compressor sound blanket included as standard equipment
• Multiple protection circuits: high-pressure switch, low-pressure transducer, liquid return protection, high/low compression ratio protection, compressor high-temperature protection, high/low voltage protection, overcurrent protection, and IPM and control board high-temperature protection
• Outdoor coil passes 1000-hour salt spray testing per ASTM B117 standard for corrosion resistance
• AHRI certified and ETL listed

Compatibility

Designed as an OEM inverter heat pump condensing unit for use in matched BOSCH split-system configurations. Specific matched indoor unit requirements should be confirmed against BOSCH AHRI-certified combination data before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified to handle A2L refrigerants, as R454B has a mild flammability classification requiring specific handling and ventilation practices under applicable codes. Disconnect and lock out all electrical power to the system before making any wiring or refrigerant connections. Follow local mechanical and electrical codes, including applicable sections of the NEC and equipment-manufacturer installation instructions, for line-set sizing, electrical disconnect requirements, and refrigerant line brazing or flaring procedures. Do not operate the unit without verifying refrigerant charge, system static pressures, and airflow through the matched indoor coil.
