718446-YTG-A-0811 • Top Discharge - The top discharge condenser fan does not disrupt neighboring areas or dry-out vegetation surrounding the unit. The warm air from the top mounted fan is blown up away from the structure and any landscaping. This allows compact location on multi-unit applications. • Condenser Coil Grille - All models utilize a stamped “Louvered” design which provides superior impact protection against smaller objects during transit and after installation.
718446-YTG-A-0811 control and less than 1% leak rate. Includes hood and mesh bird screen filter integrated into the hood, dry bulb sensor and relief damper. Separate field accessories of single enthalpy and dual enthalpy are also available. A built-in barometric relief of 25% is provided. • Single Enthalpy Sensor - Sensor replaces dry bulb sensor standard in economizer kit. Provides improved economizer operation by sensing the dry bulb temperature from outdoors plus the enthalpy content of the outdoor air.
718446-YTG-A-0811 Indoor (Evaporator) Fan Assembly Fan shall be direct drive design. Fan wheel shall be double-inlet type with forward-curved blades, dynamically balanced to operate smoothly throughout the entire range of operation. Airflow design shall be constant air volume. Bearings shall be sealed and permanently lubricated for longer life and no maintenance. Fan assembly shall be “Slip Track” (slide-out) design for easy removal and cleaning.
