Bosch 8733982683 Inverter Condenser 5 Ton 18 SEER2

Product Description

The BOSCH 8733982683 is a fully-modulating inverter-driven heat pump condenser designed for residential and light-commercial split systems in warmer climate zones. It operates on R-454B, an A2L refrigerant with low global warming potential (Low-GWP), aligning with current and upcoming refrigerant transition requirements. The unit delivers up to 15.2 SEER2 seasonal efficiency and 8.5 HSPF2 heating efficiency. The inverter drive continuously adjusts compressor speed to match actual load, reducing short-cycling and energy consumption compared to single-stage or two-stage equipment. Licensed HVAC technicians handle installation and commissioning of this unit.

This condenser is suited for residential split-system installations in warmer climates where cooling efficiency is the primary design consideration. Its inverter-drive architecture makes it a strong fit for new construction and retrofit projects that require high-efficiency ratings to meet energy code requirements. The R-454B refrigerant charge requires A2L-certified handling procedures and compatible line sets, service equipment, and indoor coil or air handler pairings. Installers should verify that the matched indoor unit is rated and approved for use with A2L refrigerants before beginning work.

Key Features

• Fully-modulating inverter drive adjusts compressor speed continuously to match load demand
• R-454B (A2L) refrigerant with low global warming potential meets current Low-GWP requirements
• Up to 15.2 SEER2 cooling efficiency rating
• Up to 8.5 HSPF2 heating efficiency rating
• 5-ton nominal capacity for larger residential or light-commercial applications

Compatibility

Designed as an OEM inverter heat pump condenser for split-system applications. All matched indoor components must be rated and approved for use with R-454B A2L refrigerant. Consult BOSCH system matching guides to confirm compatible air handlers or fan coils before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician certified for A2L refrigerant handling, as R-454B is a mildly flammable refrigerant class requiring specific safety protocols and approved service equipment. Power down and lock out the electrical supply to the system before making any wiring or refrigerant connections. Follow all applicable local mechanical codes and NEC requirements for disconnect sizing, wire gauge, and ground connections. Do not use service equipment, line sets, or indoor coils that are not rated for A2L refrigerant use.
