Installation Requirements

Unpack and inspect contents. Place on a level, stable outdoor pad.

  1. Select Location: Minimum 24 inches clearance on all sides, away from windows and vegetation.
  2. Prepare Pad: Use a level, concrete pad or approved composite pad.
  3. Connect Refrigerant Lines: Braze lines to service valves following EPA guidelines.
  4. Connect Electrical: Run 208/230V power and low-voltage control wiring from indoor unit.
  5. Connect Condensate Drain: Ensure proper drainage from indoor coil.
  6. Evacuate and Charge: Deep vacuum system and charge with R-410A refrigerant per nameplate.

WARNING! Installation must be performed by a qualified HVAC technician. Disconnect all power before servicing. Refrigerant handling requires EPA certification.

First-Time Setup & Startup

After installation, perform initial startup and system check.

  1. Power On: Restore power to indoor air handler/furnace and outdoor unit.
  2. Thermostat Setup: Set compatible thermostat to COOL mode, temperature below room temp.
  3. System Check: Listen for compressor and fan start. Verify airflow from indoor vents.
  4. Measure Performance: Check superheat/subcooling, system pressures, and temperature drop across indoor coil.
  5. Final Inspection: Ensure all access panels are secure and area is clear.

CAUTION! Do not operate without proper refrigerant charge. Allow 5 minutes between shutdown and restart to prevent compressor damage.

Specifications

Controls and Operation

Primary control is via the indoor thermostat. Unit has internal safety controls and a contactor.

Thermostat Operation: Set to COOL, select desired temperature. Fan can be set to AUTO or ON.

Unit Operation: On a call for cooling, thermostat energizes the contactor in the outdoor unit, starting the compressor and fan.

Safety Controls: High and low pressure switches will shut off compressor if pressures exceed safe limits. Internal time delay prevents short cycling.

LED Status Light (if equipped): Blink codes indicate normal operation or fault conditions (see Troubleshooting).

Connecting to Indoor Unit

Must be matched with an approved American Standard indoor coil and air handler or furnace.

  1. Match Capacity: Ensure indoor unit capacity matches 5-ton outdoor unit.
  2. Refrigerant Lines: Connect liquid and vapor lines using correct size tubing.
  3. Control Wiring: Connect low-voltage (24V) wires (Y, C, O/B, G, etc.) between thermostat, indoor unit, and outdoor unit.
  4. Line Voltage: Connect L1 and L2 from disconnect to outdoor unit terminals.

Tip: Refer to the indoor unit installation manual for specific wiring diagrams and requirements.

Maintenance Procedures

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

  1. Annual Professional Service: Recommended before each cooling season.
  2. Clean Condenser Coil: Gently brush debris from fins. Use coil cleaner if heavily soiled. Rinse with low-pressure water from inside out.
  3. Clear Area: Keep 24-inch perimeter free of grass, leaves, and debris.
  4. Inspect Fan Motor & Blades: Check for smooth operation and cracks.
  5. Check Electrical Connections: Tighten any loose connections in disconnect and unit panel.
  6. Inspect Refrigerant Lines: Look for insulation damage or signs of leaks.

WARNING! Do not use a pressure washer. Do not bend or damage aluminum fins. Only qualified technicians should check refrigerant charge or electrical components.

Safety Features

High-Pressure Switch: Opens circuit if discharge pressure is excessive. Low-Pressure Switch: Opens circuit if suction pressure is too low. Internal Time Delay: Prevents compressor from restarting for approximately 5 minutes after shutdown. Compressor Overload Protection: Built-in thermal protection. Fused Disconnect: Required in field-installed disconnect box.

Care & Cleaning

Disconnect power at the disconnect switch before cleaning.

Exterior: Wipe cabinet with a damp cloth. Do not use harsh chemicals or abrasives.
Coil: Clean as described in Maintenance. Keep fins straight.
Surrounding Area: Keep free of obstructions, mulch, and grass clippings.

CAUTION! Never insert objects into fan grille while power is connected. Ensure unit is completely dry before restoring power.

Troubleshooting

SymptomPossible CauseCorrective Action
Unit does not startPower off, blown fuse, tripped breaker, thermostat settingCheck disconnect and breaker. Verify thermostat is in COOL mode below room temp. Wait 5 minutes for time delay.
Fan runs, compressor does notLow refrigerant charge, faulty capacitor, pressure switch openCheck for refrigerant leak. Test capacitor and pressure switches. Call a technician.
Unit cycles on/off frequently (short cycles)Dirty filter/coil, low charge, oversized unit, thermostat locationClean indoor filter and outdoor coil. Check charge. Ensure proper unit sizing. Call a technician.
Reduced cooling capacityDirty air filter, dirty coils, low refrigerant, restricted airflowReplace filter. Clean indoor and outdoor coils. Check ductwork for obstructions. Call a technician for charge check.
Unusual noiseLoose panel, debris in fan, failing motor or compressorTurn unit off. Tighten access panels. Clear debris from fan. If noise persists, call a technician.
Ice on refrigerant lines or coilLow airflow (dirty filter/coil), low refrigerant chargeTurn system OFF. Let ice melt. Replace filter. Clean coils. If problem recurs, call a technician immediately.

Reset: Turn thermostat to OFF. Turn off power at disconnect for 1 minute. Restore power and thermostat.
