Unpack and inspect unit for shipping damage. Select a suitable outdoor location.
WARNING! Installation must be performed by a qualified HVAC technician. Incorrect installation can cause property damage, personal injury, or death. Handle refrigerant according to EPA regulations.
After installation is complete and verified, power on the system.
CAUTION! Do not operate without proper refrigerant charge. Allow unit to run for at least 10 minutes to stabilize before taking measurements.
Primary control is via the indoor thermostat. The condenser unit has no user-serviceable controls internally.
Thermostat Operation: Set to COOL, HEAT (if paired with furnace/heat pump), FAN (ON/AUTO), and desired temperature. The thermostat sends a signal to start the condenser and indoor fan.
Unit Operation: When cooling is demanded, the contactor in the condenser energizes, starting the compressor and condenser fan motor. The high and low-pressure switches provide safety shutdown.
Normal Sounds: Hum from compressor, airflow from fan, refrigerant flow. A soft click may be heard when contactor engages/disengages.
This condenser must be matched with an approved American Standard indoor coil and air handler or furnace.
Tip: Refer to the indoor unit installation manual for specific wiring diagrams and compatibility requirements.
Regular maintenance is required for efficiency and longevity. Disconnect power before any service.
WARNING! Do not attempt to service refrigerant circuit. Only EPA-certified technicians may handle refrigerant.
High-Pressure Switch: Opens electrical circuit if discharge pressure becomes excessively high, stopping the compressor.
Low-Pressure Switch: Opens electrical circuit if suction pressure becomes too low, protecting the compressor.
Compressor Overload: Internal thermal protector.
Fused Disconnect: Required field installation provides overcurrent protection.
Disconnect power at the disconnect switch before cleaning.
Condenser Coil: Clean annually or as needed. Use a soft brush to remove loose debris from fins. Flush gently with a garden hose from the inside (fan side) outward. Straighten any bent fins with a fin comb.
Cabinet: Wipe exterior with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
CAUTION! Never use a pressure washer. Do not spray water directly into electrical compartments or fan motor. Ensure unit is completely dry before restoring power.
This product complies with applicable U.S. safety and performance standards. The refrigerant circuit contains R-410A, a non-ozone-depleting HFC. Proper recovery and reclamation of refrigerant is required by EPA Section 608 regulations. This equipment is designed for installation in accordance with National Electrical Code (NEC) ANSI/NFPA 70 and local building codes.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Unit does not start | Power off, tripped breaker, blown fuse, thermostat setting | Check disconnect and breaker. Verify thermostat is set to COOL below room temp. Check fuses in disconnect. |
| Fan runs, compressor does not | Low refrigerant charge, faulty capacitor, internal overload tripped | Call for professional service to check charge and electrical components. |
| Unit cycles on/off frequently (short cycles) | Dirty filter/coil, low charge, oversized unit, thermostat location | Replace air filter. Clean coils. Have technician check charge. |
| Reduced cooling capacity | Dirty air filter, dirty coils, low refrigerant charge, restricted airflow | Replace filter. Clean indoor and outdoor coils. Call for professional service. |
| Unusual noise (rattling, grinding) | Loose parts, debris in fan, failing motor or compressor | Turn unit off. Check for loose panels or debris. Call for professional service. |
| Ice on refrigerant lines or indoor coil | Low airflow (dirty filter/coil), low refrigerant charge | Turn system off. Replace filter. Allow ice to melt. Call for professional service. |
Note: Most repairs require a qualified HVAC technician. Do not attempt to repair electrical or refrigerant components yourself.
