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 equipment failure, property damage, personal injury, or death. Disconnect all power before servicing.
After installation, perform initial startup and system check.
CAUTION! Do not operate without proper refrigerant charge. Allow unit to stabilize for 10-15 minutes before taking measurements.
Primary control is via indoor thermostat. Unit has internal safety and operating controls.
Thermostat Operation: Set to COOL, AUTO fan, desired temperature. Unit cycles on/off to maintain setpoint.
Internal Controls: High pressure switch (opens on excessive discharge pressure), Low pressure switch (opens on low suction pressure), Compressor internal overload, Fan motor thermal protection, Anti-short cycle timer (typically 5 minutes).
Normal Operation Signs: Steady hum from compressor, Airflow from top discharge, Warm air discharging from top, Condensate draining from indoor unit.
Must be matched with approved American Standard indoor coil or air handler.
Tip: Always refer to the indoor unit installation manual for specific wiring and piping requirements.
Regular maintenance ensures efficiency and longevity. Perform at least annually, preferably before cooling season.
WARNING! Do not use pressure washer on coil fins. Do not bend fins. Electrical work should be done by qualified personnel.
High/Low Pressure Switches: Protect compressor from abnormal operating pressures. Compressor Overload: Internal thermal protection. Anti-Short Cycle Timer: Prevents compressor rapid cycling (minimum 5 minutes off). Fused Disconnect: Provides overcurrent protection at outdoor unit.
Keep unit clear of vegetation, leaves, and snow. Clean coil annually. Inspect base pan for proper drainage.
CAUTION! Always disconnect power before cleaning. Do not use sharp objects to clean fins. Do not operate with damaged coil fins.

| Symptom | Possible Cause | Corrective Action |
|---|---|---|
| Unit does not start | Power off, tripped breaker, thermostat setting, anti-short cycle timer | Check disconnect and breaker. Verify thermostat is in COOL, set below room temp. Wait 5 minutes. |
| Fan runs, compressor does not | Low refrigerant (low pressure switch open), faulty capacitor, compressor overload | Check refrigerant charge. Test capacitor. Allow compressor to cool if overloaded. |
| Compressor short cycles | Dirty coil, restricted airflow, overcharge, faulty pressure switch | Clean condenser coil. Check indoor filter and blower. Check refrigerant charge. |
| Reduced cooling capacity | Dirty air filter, dirty coils, low refrigerant, restricted airflow | Replace filter. Clean indoor and outdoor coils. Check charge and ductwork. |
| Loud or unusual noise | Loose parts, debris in fan, failing fan motor, compressor issue | Turn off power. Tighten cabinet panels. Clear debris. If noise persists, contact technician. |
| Ice on refrigerant lines or indoor coil | Low airflow (dirty filter/coil), low refrigerant charge | Turn system OFF. Replace filter. Check coil cleanliness. Call for service to check charge. |
Reset: Turn thermostat OFF, turn disconnect OFF for 30 seconds, then restore power.
