Installation

Unpack and inspect contents. Place on a level, stable pad away from obstructions.

Position Unit: Place on a concrete pad or approved composite stand. Ensure minimum clearances (24" on all sides, 48" above).
Connect Refrigerant Lines: Braze lineset to unit service valves using nitrogen purge. Ensure connections are leak-tight.
Connect Electrical: Run high-voltage power (240V) and low-voltage control wiring from disconnect and indoor unit to outdoor terminal block.
Connect Drain Line (if applicable): For units with integrated overflow switch.
Evacuate and Charge: Evacuate system to 500 microns, then charge with specified R-410A refrigerant by weight.

WARNING! Installation must be performed by a qualified HVAC technician. High voltage and refrigerant can cause serious injury or death. Follow all local codes and manufacturer instructions.

First-Time Setup & Startup

After installation, perform initial startup and system check.

Power On: Ensure indoor unit power is on. Turn on outdoor disconnect switch.
Thermostat Setup: Configure compatible thermostat (set to COOL, desired temperature below room temp).
System Check: Listen for compressor and fan start-up. Verify correct airflow from indoor vents.
Measure Performance: Check superheat/subcooling, system pressures, and voltage/amperage against specifications.
Customer Orientation: Explain thermostat operation, filter maintenance, and basic troubleshooting.

CAUTION! Do not start unit without proper refrigerant charge and airflow. Ensure electrical connections are tight and correct.

Controls and Settings

Primary control is via the indoor thermostat. Unit has internal safeties and control board.

Thermostat Settings: MODE (COOL, OFF, HEAT* with matched furnace), FAN (AUTO, ON), Temperature Setpoint.

Unit Control Board: Manages compressor timing, fan operation, and system safeties (high/low pressure, compressor overload). No user-serviceable settings on outdoor unit.

LED Diagnostic Light: Located on control board inside service panel. Flash codes indicate system status or fault (see Diagnostics section).

Connecting to System Components

This condenser must be matched with an approved American Standard indoor coil (evaporator) and air handler or furnace.

Turn off all power at disconnect and indoor unit.
Match Lineset: Connect 3/8" liquid and 3/4" or 7/8" suction lines to corresponding service valves.
Connect Control Wiring: Connect low-voltage wires (typically 18 AWG) from indoor unit to terminal block (Y, C, O/B, G, etc.) as per wiring diagram.
Connect Power Wiring: Connect high-voltage lines (L1, L2, Ground) from disconnect to unit terminal block.

Tip: Refer to the unit's wiring diagram on the inside of the service panel door for specific connections.

Operation & Maintenance

For normal operation, set thermostat to COOL and desired temperature.

Regular Maintenance: Schedule annual professional maintenance before cooling season.
Filter Replacement: Replace indoor air filter every 1-3 months to maintain airflow and efficiency.
Outdoor Unit Care: Keep area around condenser clear of leaves, grass, and debris (maintain 24" clearance).
Coil Cleaning: Gently clean outdoor coil with a garden hose (power off) if visibly dirty. Do not use high pressure.
Winterization (optional): In snowy climates, a condenser cover can be used, but ensure unit is powered off.

WARNING! Always turn off power at the disconnect before performing any cleaning or maintenance near the unit.

Diagnostics & Alerts

The control board has an LED that flashes to indicate status.

LED Flash Pattern	Likely Condition
1 Flash	Normal Operation
2 Flashes	Loss of Charge / Low Pressure
3 Flashes	High Pressure Fault
4 Flashes	Compressor Overload / Lockout
5 Flashes	Low Voltage or Power Loss
Continuous On	Control Board Fault

Note: For specific fault codes and advanced diagnostics, a qualified technician with proper tools is required.

Care & Cleaning

Turn off power at disconnect. Use a garden hose to gently rinse dirt and debris from the outdoor coil fins from the inside out. Straighten any bent fins with a fin comb. Keep the top grille free of debris.

CAUTION! Do not use a pressure washer, which can damage the delicate fins. Do not use chemical cleaners unless specified by American Standard.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit not turning on	Power loss, tripped breaker, thermostat setting	Check disconnect switch and circuit breakers. Verify thermostat is set to COOL below room temp.
Fan runs, compressor doesn't	Low refrigerant, faulty capacitor, internal overload	Check for fault code. Call for professional service.
Reduced cooling	Dirty filter, dirty coils, low refrigerant	Replace indoor filter. Clean outdoor coil. Call for service to check charge.
Unit cycles on/off rapidly	Dirty filter, blocked airflow, faulty sensor	Replace filter. Ensure vents are open. Call for service.
Ice on refrigerant lines or indoor coil	Low airflow, low refrigerant charge	Turn system OFF. Replace filter. Call for service once ice melts.
Unusual noise	Debris in fan, loose parts, failing motor	Turn power OFF. Check for and remove debris. If noise persists, call for service.

Reset: Some faults may auto-reset. Turning thermostat OFF for 5 minutes, then back ON may reset minor lockouts.
