CABINET—Galvanized steel with powder coat paint finish. The powder coat paint finish is high gloss, durable and capable of withstanding a 1000-HR salt spray test per ASTM B117. The unit is of the frame and panel type of construction which allows all access panels to be opened or removed without affecting the structural strength of the unit. Fastening screws are also of the 1000-HR type. Stamped louver panels offer 100% protection for the condenser coil
BASE PAN—Galvanized steel with powder coat paint finish
SERVICE ACCESS—Control box with separation between line and control voltages, as well as compressor and other refrigerant controls are accessible through removable panel without affecting normal operation of unit
FAN MOTOR—Condenser fan motor(s) are mounted on removable top panel(s) which bring the motor(s) out to you and expose entire condenser coil for cleaning
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. Compressors have an internal pressure relief assembly to protect against excessive pressure differential. There is a separate compressor compartment for easy service access
COMPRESSOR CRANKCASE HEATER—External wraparound heater helps prevent refrigerant migration to the compressor oil during long off periods
CONDENSER 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 450 PSIG internal pressure
REFRIGERANT CONNECTIONS—All field sweat joints are made external of the unit and are located close to the ground for a neat looking installation
LOW AMBIENT CONTROL—A pressure sensitive fan cycling control allows operation of units down to 0°F [-18°C].
HIGH PRESSURE CONTROL—Manual reset control deactivates system if abnormally high pressure occurs
LOW PRESSURE CONTROL—Automatic reset control deactivates system if abnormally low pressure or refrigerant loss occurs
SERVICE VALVES—Standard on liquid and suction lines
CONDENSER FAN MOTORS—Direct drive, single-phase permanently lubricated “PSC” motors with inherent overload protection
TRANSFORMER—50VA step-down type, from Line to 24 volts
CONTACTOR—The contactor is an electrical switch which operates the compressor and condenser fans. Its 24 volt coil is activated through the High Pressure Control and Low Pressure Control on a call for cooling
EQUIPMENT GROUND—Lug for field connection of ground wire
TESTING—All units are run tested at the factory prior to shipment. Units are shipped with a holding charge of nitrogen
CONTROL BOX—The control box is located in the top corner of the cabinet providing for easy access through a service panel
COMPRESSOR TIME DELAY CONTROL—Compressor will remain off for five minutes after power or thermostat interruption, allowing system pressures to equalize. (Model No. RXMD-B01)
FILTER/DRIER—A liquid line filter drier is shipped with each unit for field installation.
