Heat Pump Units
3 to 5 Nominal Tons
WeatherMaker® 50KCQ rooftop units were designed to be easy to install, maintain, and operate, with customer-requested features including a gage port, centralized control center, plug-and-play accessory board, ''no-strip screw'' collars, and handled access panels. Units are field-convertible to horizontal airflow without special adapter curbs or kits, making it easy for the installer to adjust to unexpected jobsite complications. Units are pre-wired and pre-charged with Puron (R-410A) refrigerant and are factory tested.
Performance Features
- ASHRAE 90.1 compliant
- Single-stage cooling capacity control
- Up to 14.3 SEER, 12.2 EER and 8.2 HSPF
- Cooling operating range up to 115 °F (46°C) and down to 25°F (-4°C) using winter start kit
- Innovative non-corrosive composite condensate pan in accordance with ASHRAE 62 Standard, sloping design; side or center drain
- Pre-painted exterior panels and primer-coated interior panels tested to 500 hours salt spray protection
Maintenance Features
- Control terminal board facilitating simple safety circuit troubleshooting and simplified control box arrangement
- Access panels with easy grip handles
