7.5 TON FEATURES & BENEFITS

1. 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. All access panels can be opened or removed without affecting the structural strength of the unit. Stamped louvered panels offer 100% protection for the condenser coil.

2. EQUIPMENT GROUND—Lug for field connection of ground wire.

3. CONTACTOR—The contactor is an electrical switch which operates the compressor and outdoor fans. Its 24 volt coil is activated on a call for cooling or heating.

CONTROL BOX

4. TRANSFORMER—75 VA step-down type, from Line to 24 volts

with resetable circuit breaker.

5. CAPACITOR—Help provide starting torque necessary to boost the condenser fan motor to operating speed by directing their stored energy to the starter winding in step with the running winding.

6. DEMAND DEFROST CONTROL—Used when unit is in heating mode to defrost outdoor coil.

7. AUTO-RESET HIGH PRESSURE CONTROL, AND AUTO-

RESET LOW PRESSURE CONTROL—To provide compressor

protection under abnormally high head pressure conditions (outdoor fan failure, restriction, dirty coil, etc.) or abnormally low suction pressure conditions (restrictions, TEV failure, loss of charge, indoor blower failure, etc.) while eliminating nuisance tripping sometimes experienced with conventional control systems.

7.5 TON

FEATURES & BENEFITS

8. COIL—Constructed with copper tubes and aluminum fins mechan -

ically bonded to tubes for maximum heat transfer capabilities. All coil assemblies are leak tested up to 550 PSIG (3792 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.

9. BASE PAN—Galvanized steel with powder coat paint finish.

10. 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 top reduce vibration and noise.

11. TX VALVE—Used when unit is in heating mode and outdoor coil functions as evaporator.

12. CRANKCASE HEATER—Minimizes refrigerant migration to com pres sor cump.

13. SUCTION LINE ACCUMULATOR—To prevent liquid slugginig of compressor.

14. REFRIGERANT CONNECTIONS—All field sweat joints are made external of the unit and are located close to the ground for a neat looking installation.

15. SERVICE VALVES—Standard on liquid line and vapor line.

16. REVERSING VALVE—Sized for maximum capacity and efficiency,

24V coil, energized in heating.

8. 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 550 PSIG [3792 kPa] internal pressure.

LOW AMBIENT CONTROL—A pressure sensitive fan cycling control

allows cooling operation of unit down to 0°F [-18°C].
