Energy tandards. ll units are manufactured to meet extensive quality control protocol from start to finish through an automated control system, which provides continuous monitoring of each unit and performs quality control checks as equipment progresses through the production process. orrosion protected, heavy gage galvanized sheet metal lined with / 2 in. thick, / 2 lb. acoustic type insulation. ompressor isolating springs are specially selected for each compressor size. ermanent split capacitor () three-speed blowers lower motors operate at lower temperatures ealed refrigerant circuit provided with a standard thermostatic expansion valve (TXV) include a rotary, reciprocating, or scroll compressor. eversing valve (4-way valve) -to-refrigerant coaxial (tube in tube) coil Enhanced aluminum fin/rifled copper tube air-to-refrigerant heat exchanger coil an motor insulation and compressor springs for sound isolation ow speed blowers are utilized for quiet operation through reduced outlet air velocities our airflow configurations for horizontal units Horizontal units are field convertible from left or right discharge to back discharge Three airflow patterns for vertical units with right or left return tandard water temperature range between 60 and 95 TDD UIT ETUE Extended water temperature range between 20 and 0 flow rates as low as.5 gpm per ton High-pressure switch ow-pressure sensor to detect loss of refrigerant ow air temperature sensor to safeguard against freezing loop temperature monitoring Voltage protection coil freeze protection tandard electronic condensate overflow shutdown ll units are pre-wired and factory charged with refrigerant Horizontal units are provided with factory-installed hanger isolation brackets. Vertical units are provided with an internally trapped condensate drain to reduce labor associated with installing an external trap for each unit. connections (T) and condensate drains (T) are anchored securely to the unit cabinet. omplete solid-state control system provides control of unit compressor, reversing valve, fan, safety features, and troubleshooting fault indication features. 2
