7.5 TON FEATURES AND BENEFITS
BASE RAILS—Commercial grade base rails for handling any rigging.
HIGH PRESSURE CONTROL—Manual reset control deactivates system if abnormally high pressure occurs.
CABINET—Galvanized steel with powder coat paint finish. The powder coat paint finish is high gloss, durable and capable of withstanding a 1000-hour salt spray test per ASTM B 117. The unit is of the frame and panel type of construction secured by 1000-hour screws. This allows all access panels to be opened or removed without affecting the structural strength of the unit. Stamped louvered panels offer 100% protection for the condenser coil.

COILS—Constructed with copper tubes and aluminum fins mechanically bonded to tubes for maximum heat transfer capabilities. All coil assemblies are leak tested up to 300 PSIG [2068 kPa] internal pressure.
SERVICE ACCESS—Control box with separate line and control voltages, as well as compressor and other refrigerant controls are accessible through access panels. An electrical access cover may be opened or removed without affecting normal operation of the unit. Condenser fan motors are equipped with molded plugs for easy removal. Louver panels and end access panel can be removed for coil cleaning.
BASE PAN—Galvanized steel with powder coat paint finish.
COMPRESSOR—The Scroll Compressor is hermetically sealed with internal high temperature protection, and durable insulation on motor windings. The entire compressor is mounted on rubber grommets to reduce vibration and noise.
TX VALVE—Used when unit is in heating mode and outdoor coil functions as evaporator.
FILTER DRIER—Installed in liquid line.
CRANKCASE HEATER—Minimizes refrigerant migration to compressor
sump.
HOT GAS SENSOR (Discharge Line Thermostat)—Control prevents damage to compressor under abnormal conditions; loss of charge protection.
REVERSING VALVE—Sized for maximum capacity and efficiency, 24V coil, energized in heating.
LOW PRESSURE CONTROL—Automatic reset control deactivates system if refrigerant loss occurs. Located in suction line.
SUCTION LINE ACCUMULATOR—To prevent liquid slugging of compressor.
REFRIGERANT CONNECTIONS—All field sweat joints are made external of the unit and are located close to the ground for a neat looking installation.
SERVICE VALVE—Standard on liquid line, optional on vapor line.
CONDENSER FAN MOTORS—Direct drive, single-phase permanently lubricated “PSC” motors with inherent overload protection.
LOW AMBIENT CONTROL—A pressure sensitive fan cycling control
allows cooling operation of unit down to 0°F [-18°C]
