Installation

Unpack and inspect for shipping damage. Select a suitable outdoor location.

Location: Place on a level, stable pad (concrete or composite). Ensure clear airflow (min 24" clearance on all sides, 48" above).
Electrical: Connect to a dedicated 230V, 60Hz circuit with proper disconnect and overcurrent protection as per NEC and local codes.
Refrigerant Lines: Connect pre-charged, insulated copper lineset from indoor unit. Brazing must be done with nitrogen purge.
Condensate Drain: Ensure indoor unit drain line is properly installed and trapped.
Final Check: Verify all electrical connections are tight and lineset is insulated and sealed.

WARNING! Installation must be performed by a qualified HVAC technician. Incorrect installation can cause property damage, personal injury, or death. Disconnect all power before servicing.

First-Time Setup & Startup

After installation, perform initial startup and system check.

Pre-Start Check: Verify correct refrigerant charge using subcooling method. Check electrical voltage at unit.
Thermostat: Set indoor thermostat to OFF. Restore power to indoor and outdoor units.
Startup: Set thermostat to COOL mode, temperature below room temp. Unit should start after a short delay.
Performance Check: Listen for normal operation. Check for adequate airflow from indoor vents. Measure temperature drop across indoor coil (typically 15-20°F).
Finalize: Register product online for full warranty coverage.

CAUTION! Do not operate without correct refrigerant charge. Ensure fan guard is secure before powering on.

Controls and Operation

Primary control is via the indoor thermostat. Unit has internal protection controls.

Thermostat Operation: Set to COOL, AUTO FAN, desired temperature. System cycles automatically.

Unit Controls & LEDs: Control board includes diagnostic LED. Normal operation: steady light. Fault codes indicated by flash patterns (see Troubleshooting).

Protections: High-pressure switch, low-pressure switch, compressor overload, anti-short cycle timer (approx. 5 min).

Connecting to Indoor Unit

Must be paired with a matched American Standard indoor coil (e.g., TXC) or furnace coil.

Ensure indoor unit is installed and lineset is routed.
Connect refrigerant lines to service valves. Flare or braze connections.
Connect low-voltage control wires (typically 24V) from indoor unit to outdoor terminal block (Y, C, O/B if heat pump).
Connect high-voltage power lines through disconnect to terminal block (L1, L2).

Tip: Always use a vacuum pump to evacuate the lineset and coil to below 500 microns before opening service valves.

Maintenance Procedures

Regular maintenance ensures efficiency and longevity. Perform at least annually, preferably before cooling season.

Power Off: Turn off power at disconnect and indoor unit.
Clean Coil: Gently brush debris from outdoor coil fins. Use a coil cleaner if heavily soiled, rinse with low-pressure water.
Clear Area: Remove leaves, grass, and debris within 2 feet of unit.
Check Fan: Inspect fan blades for cracks and ensure it spins freely.
Inspect Electrical: Check for loose connections, corrosion, or damaged insulation.
Check Refrigerant Lines: Inspect insulation and look for signs of oil (indicates leak).
Restart: Restore power and verify normal operation.

WARNING! Do not insert fingers or tools into fan area. Do not use a pressure washer on the coil.

Safety Features

High and Low Pressure Switches: Protect compressor from abnormal pressures. Compressor Overload: Internal thermal protection. Anti-Short Cycle Timer: Prevents rapid cycling. Fused Disconnect: Required for overcurrent protection.

Care & Cleaning

Keep unit clear of obstructions. Clean coil annually as described. Wipe cabinet with damp cloth if needed.

CAUTION! Do not use harsh chemicals or abrasive cleaners on cabinet or coil. Never operate unit with side or top panels removed.

Regulatory Information

This product complies with applicable U.S. safety and performance standards. R-410A refrigerant is non-ozone depleting. Proper refrigerant recovery is required by EPA Section 608.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit does not start	Power off, thermostat setting, blown fuse/breaker, safety lockout	Check power at disconnect & breaker. Verify thermostat settings. Wait 5 mins for anti-short cycle. Check diagnostic LED.
Unit runs but does not cool	Dirty filter/coil, low refrigerant, faulty thermostat	Check/change indoor air filter. Clean outdoor coil. Check for ice on lines. Call technician for charge check.
Unit cycles on/off rapidly (short cycles)	Dirty coil, overcharge/undercharge, restricted airflow	Clean coils. Check filters and indoor blower. Call technician.
Loud or unusual noise	Loose parts, debris in fan, failing motor or compressor	Turn off power. Check for loose panels or debris. If internal, call technician.
Ice on refrigerant lines or outdoor unit	Low airflow, low refrigerant charge	Turn system OFF. Check/replace air filter. Ensure vents are open. Call technician when thawed.

Diagnostic LED: Steady ON = normal. Flashing = fault code (refer to service manual for pattern interpretation).

Service: Contact your qualified American Standard HVAC dealer. Do not attempt major repairs yourself.
