The HVAC Mirage 12000 BTU 18 SEER2 Condenser (OFWB120D) is a high-efficiency outdoor unit designed to provide reliable cooling when paired with a compatible indoor air handler.
As a standalone inverter-driven condenser, the OFWB120D is engineered for variable speed comfort and high-efficiency performance. It is explicitly designed to be paired with compatible HVAC Mirage indoor units to complete a single-zone configuration. Featuring eco-friendly low-GWP refrigerant, this unit meets rigorous efficiency standards while delivering reliable outdoor performance.
Outdoor Condenser
- Electrical: Requires a dedicated 110V (115V / 60Hz 1Ph) circuit.
- Line Set: Requires 3/8" Liquid x 7/8" Suction copper line set (NOT INCLUDED).
- Note: Indoor air handler and remote control are NOT INCLUDED.
- Note: Wall sleeve or mounting bracket is NOT INCLUDED.
Pro-Installer Tip: When installing the OFWB120D condenser, always ensure flare fittings are torqued to factory specifications using a Digital Torque Wrench. To prevent refrigerant loss and ensure system longevity, pull a vacuum below 500 microns for at least 15 minutes before opening service valves. Use 14/4 AWG stranded wire between the indoor and outdoor sections to prevent "E1" communication codes, strictly following EPA Section 608 mandates.
- 18 SEER2 efficiency rating for reduced energy consumption and operational savings.
- Inverter-driven compressor ensures precise, variable speed climate control.
- Durable, weather-resistant cabinet engineered for harsh outdoor elements.
- Quiet operation optimized for residential or light commercial environments.
