1. CABINET—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.
4. TRANSFORMER—75 VA step-down type, from Line to 24
volts with resetable circuit breaker.
5. AUTO-RESET HIGH PRESSURE CONTROL, AND AUTORESET 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.
6. COIL—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.
7. 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.
8. BASE PAN—Galvanized steel with weather-resistant baked
enamel finish.
9. 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.
10. SUCTION LINE ACCUMULATOR—To prevent liquid slugging of compressor.
11. REFRIGERANT CONNECTIONS—All field sweat joints are
made external of the unit and are located close to the ground
for a neat looking installation
12. SERVICE VALVES—Standard on liquid line and vapor line.
