Features at a Glance

Key components: Weather-resistant galvanized steel cabinet, Scroll compressor, High-efficiency aluminum coil, Liquid and suction line service valves, Electrical disconnect location.

Installation

Unpack and inspect for shipping damage. Select a level, stable outdoor location with adequate clearance.

1. Place Condenser Pad: Install on a level, solid pad (concrete or composite).
2. Connect Refrigerant Lines: Braze lines to indoor coil; pressure test with dry nitrogen.
3. Connect Electrical: Run high-voltage power (240V) to disconnect; connect low-voltage control wires from thermostat.
4. Evacuate and Charge: Deep vacuum system; charge with specified amount of R-410A.

WARNING! Installation must be performed by a qualified HVAC technician in accordance with all local codes and the National Electrical Code (NEC). Disconnect all power before servicing.

First-Time Setup & Startup

After installation, perform initial startup and system check.

1. Verify Connections: Ensure all electrical and refrigerant connections are tight and secure.
2. Set Thermostat: Install compatible thermostat; set to OFF mode.
3. Power On: Restore power at disconnect and indoor air handler/furnace.
4. Start System: Set thermostat to COOL mode, temperature below room temp. Listen for proper compressor and fan operation.
5. Check Performance: Measure temperature drop across indoor coil (typically 15-20°F). Verify refrigerant pressures are within specified range.

CAUTION! Do not operate without proper refrigerant charge. Allow unit to complete a full cycle before adjusting settings.

Specifications

• Model: 5A7A5024A
• Cooling Capacity: 2 Tons (24,000 BTU/H)
• Energy Efficiency Ratio (EER): Up to 13.0 (varies with indoor unit)
• Refrigerant Type: R-410A
• Electrical Data: 208/230V, 1 Phase, 60 Hz
• Maximum Overcurrent Protection: 25 Amps
• Minimum Circuit Ampacity: 15.2 Amps
• Operating Ambient Temperature Range: 55°F to 115°F

Controls and Operation

Primary control is via the indoor thermostat. The unit features internal protection controls.

Thermostat Operation: Set to COOL, AUTO FAN, and desired temperature. System will cycle automatically.

Internal Safeties: High-pressure switch, low-pressure switch, compressor overload, time-delay relay (typically 5 minutes) to prevent short cycling.

Normal Operation Sounds: Hum of compressor, airflow from fan. A slight hiss after shutdown is normal (refrigerant equalizing).

Connecting to Indoor Unit & Thermostat

This condenser must be paired with a matching American Standard indoor coil and air handler or furnace.

1. Match Systems: Ensure indoor unit is AHRI-certified match for 5A7A5024A.
2. Refrigerant Lines: Connect via field-supplied copper line set of correct size and length.
3. Low-Voltage Wiring: Connect thermostat wires (typically Y, C, G) from indoor unit to condenser terminal strip.
4. Power Wiring: Run dedicated 240V circuit from main panel to outdoor disconnect, then to unit.

Tip: Label all wires during installation for easier future service.

Maintenance Procedures

Regular maintenance ensures efficiency and longevity. Disconnect power before any service.

1. Clean Condenser Coil: Annually, gently clean exterior coil fins with a soft brush or low-pressure water spray. Remove debris (leaves, grass).
2. Check Electrical Connections: Annually, tighten terminal connections at contactor and compressor.
3. Inspect Fan Motor & Blades: Ensure fan spins freely; blades are clean and undamaged.
4. Check Refrigerant Lines: Inspect for insulation damage on suction line.
5. Professional Service: Schedule annual professional maintenance including refrigerant charge check, amp draw measurement, and safety control inspection.

WARNING! Do not use a pressure washer or insert objects into the coil fins. Do not attempt to service refrigerant system.

Safety Features

High and Low Pressure Switches: Shut off compressor if refrigerant pressures are outside safe limits. Compressor Overload: Internal thermal protection. Time Delay: Prevents compressor from restarting for approximately 5 minutes after shutdown to protect it. Fused Disconnect: Required in field-installed power disconnect for overcurrent protection.

Care & Cleaning

Keep area around unit clear (minimum 24 inches on all sides, especially the coil side). Wash outdoor coil with garden hose (nozzle off) annually to remove dirt and pollen. Keep grass and weeds trimmed around pad.

CAUTION! Never operate unit with top grille or panels removed. Do not use chemical cleaners on coil unless specified.
