This is a manufacturer's specification plate from Bard Manufacturing Co., Inc. for HVAC equipment, specifically detailing electrical and operational specifications for multiple heating unit models.

The plate documents a single-package vertical air-handling unit assembled in the U.S.A. with serial number 404L1330625S28-02. The document specifies technical requirements across multiple heater package options, including approved heater packages with specific electrical ratings (208/230 volts, 60 Hz, single or three-phase configurations), minimum fuse ratings, and circuit breaker requirements. Key electrical ratings include compressor and motor specifications, with outdoor units operating at 238/208 volts and indoor units at 240/208 volts. The unit includes a factory refrigerant charge with R-410A at 100 PSI and 448 PSI high/236 PSI low design pressures. Standard clearance requirements are specified: 1/4 inch minimum outlet duct clearance and 10 inches minimum for inlet duct clearance. The specification plate notes that only approved Bard heater packages are suitable for use with this unit, and any other heater package voids warranty and creates a safety hazard. The unit meets AHRI certification standards and is certified to ARI Standard 390-2003 for non-residential, commercial applications. Installation instructions indicate that when the optional Bard heater package is installed, the serial plate must be permanently marked to reflect the heater package addition. An Intertek certification mark and AHI certified designation are displayed on the plate.
