Installation Requirements

Unpack and inspect unit for shipping damage. Select appropriate outdoor location.

Location: Place on level concrete pad or approved mounting system with minimum 24" clearance on all sides.
Electrical: Connect to dedicated 208/230V circuit with proper disconnect and overcurrent protection as per NEC.
Refrigerant Lines: Connect pre-charged lineset to indoor coil; ensure proper brazing and evacuation.
Condensate Drain: Ensure proper drainage from indoor unit.
Final Connections: Connect low-voltage control wiring between indoor and outdoor units.

WARNING! Installation must be performed by qualified HVAC technician. Disconnect all power before servicing. Use proper personal protective equipment.

First-Time Setup & Startup

After installation, perform initial startup procedure.

Verify electrical connections: Ensure proper voltage at disconnect.
Check refrigerant charge: Use manifold gauges to verify correct superheat/subcooling.
Start system: Turn on power at disconnect, then set thermostat to cooling mode.
Monitor operation: Check for proper airflow, temperature drop, and unusual noises.
Final inspection: Verify all access panels are secure and area is clear.

CAUTION! Do not operate without proper refrigerant charge. Ensure fan rotates freely before energizing.

Controls and Operation

Unit operation is controlled by indoor thermostat. No user controls on outdoor unit.

Thermostat Settings: COOL, OFF, FAN AUTO/ON. Set desired temperature.

Normal Operation Signs: Compressor runs quietly, fan blows warm air upward, condensate drains from indoor unit.

Cycle Times: Normal cycles are 10-15 minutes minimum; frequent short cycling indicates issues.

Connecting to Indoor Unit

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

Refrigerant Lines: Connect liquid and suction lines using proper brazing techniques.

Electrical: Run high-voltage power to disconnect, then to unit.

Control Wiring: Connect 24V control wires (Y, C, O/B if heat pump) between outdoor unit and indoor unit/thermostat.

Drain Line: Ensure indoor unit condensate drain is properly installed and routed.

Tip: Always evacuate system to 500 microns before releasing refrigerant charge.

Maintenance Procedures

Regular maintenance ensures optimal performance and longevity.

Monthly: Clean debris from around unit, check for unusual noises.

Seasonal (Spring): Clean condenser coil with coil cleaner, straighten bent fins.

Annual (Professional): Check refrigerant charge, inspect electrical connections, check capacitor values, verify proper airflow.

Fan Maintenance: Lubricate motor if required (check manufacturer specifications).

Winter Preparation: Install cover if unit will be idle during freezing temperatures.

WARNING! Always disconnect power before performing any maintenance. Coil cleaning chemicals can be hazardous.

Safety Features

Built-in protection devices: High-pressure switch, low-pressure switch, compressor overload, time delay between cycles (typically 5 minutes).

Care & Cleaning

Disconnect power before cleaning. Use garden hose to gently rinse condenser coil from inside out. Do not use pressure washer.

CAUTION! Do not bend fins during cleaning. Keep electrical components dry. Never operate with dirty or blocked coil.

Troubleshooting

Symptom Possible Cause Corrective Action

Unit not running Power loss, thermostat setting, safety lockout Check disconnect and circuit breaker; verify thermostat settings; wait 5 minutes for reset.

Fan runs but compressor doesn't Capacitor failure, low refrigerant, pressure switch open Check run capacitor; verify refrigerant charge; check pressure switches.

Compressor runs but fan doesn't Fan capacitor, motor failure, obstruction Check fan capacitor; verify fan spins freely; check for voltage at fan motor.

Insufficient cooling Dirty coil, low refrigerant, restricted airflow Clean condenser coil; check refrigerant charge; check indoor filter and coil.

Unit cycles on/off frequently Dirty filter, oversized unit, low refrigerant Replace air filter; verify proper sizing; check refrigerant charge.

Unusual noises Loose parts, debris in fan, compressor issue Tighten access panels; clear debris from fan; contact technician if compressor noise.

Ice on refrigerant lines Low airflow, low refrigerant Check air filter and indoor coil; verify proper refrigerant charge.

Reset: Turn thermostat to OFF, disconnect power for 5 minutes, restore power, wait 5 minutes, then turn to COOL.

Service: Contact qualified HVAC technician. American Standard dealer locator: www.americanstandardair.com/dealer-locator
