Safety & Install Notes
- Install per national/local codes; provide clearances for service, piping, and condensate lines.
- Keep coil level for proper drainage; when wider than the furnace, use a field-fabricated adapter/transition.
- Connect the refrigerant leak sensor wiring to the leak-mitigation control kit as specified; avoid exchanger temps > 200°F that could affect the sensor.
- Use two 3/4" condensate connections (one plugged); add a properly sized trap and pitch the drain line to an open drain; consider a secondary pan where required.
- Do not install in moist, corrosive, obstructed, or hazardous locations; equipment must be grounded. Installation and servicing should be performed by qualified personnel.
Environmental & Efficiency Features
