Installation Requirements

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

Location: Place on a level, stable pad (concrete or composite) with adequate clearance (min 24" on sides, 48" above, 60" front).
Electrical Connection: Disconnect all power. Connect field-supplied wiring to unit terminal block per NEC and local codes. Unit requires 208/230V, 1-phase, 60 Hz power.
Refrigerant Lines: Connect matched indoor coil using clean, dehydrated, ACR copper tubing. Braze with nitrogen purge. Insulate suction line.
Condensate Drain: Ensure indoor unit drain line is properly installed and trapped.

WARNING! Installation and service must be performed by a qualified HVAC technician. Incorrect installation can cause injury, property damage, or equipment failure.

First-Time Startup & Commissioning

After installation, perform the following startup procedure.

Pre-Start Check: Verify all electrical connections are tight. Ensure service valves are open. Check refrigerant line insulation.
Thermostat Setup: Set compatible thermostat to OFF. Configure for two-stage cooling if applicable.
Power On: Restore power at disconnect and indoor air handler/furnace.
System Check: Set thermostat to COOL, temperature below room temp. Listen for proper compressor and fan engagement.
Measurements: Measure superheat/subcooling per charging chart on unit. Adjust refrigerant charge if necessary. Verify system pressures and temperature drop across indoor coil.

CAUTION! Do not operate without correct refrigerant charge. Allow 5 minutes between compressor cycles.

Controls and Operation

Unit operation is controlled by a compatible indoor thermostat. The unit's internal control board manages compressor staging, fan operation, and safety lockouts.

Normal Operation: Thermostat calls for cooling. Control board engages condenser fan and activates compressor (Stage 1 for moderate cooling, Stage 2 for high demand).

LED Status Light: Located on control board. Steady ON = normal operation. Flashing patterns indicate specific fault codes (see Troubleshooting).

Safety Controls: Internal high and low-pressure switches will shut down compressor if pressures exceed safe limits. Compressor has internal overload protection. System includes anti-short cycle timer (approx. 5 minutes).

Connecting to Indoor Unit & Thermostat

This condensing unit must be connected to a matched American Standard indoor coil (evaporator) and air handler or furnace.

Indoor Unit: Ensure indoor coil is properly installed and matched for 2-ton capacity.
Low Voltage Wiring: Run 24V control wiring (minimum 18 AWG) from indoor unit to outdoor unit terminal block (Y1, Y2, C, O/B, etc., as applicable). Follow wiring diagram on unit access panel.
Thermostat: Install a compatible two-stage thermostat. Connect wires per thermostat and indoor unit instructions.
System Communication: For systems with communicating capabilities, ensure proper data wire connection.

Tip: Always verify low-voltage connections are correct and secure to prevent erratic operation.

Maintenance Procedures

Regular maintenance ensures efficiency and longevity. DISCONNECT ALL POWER SOURCES BEFORE SERVICING.

Annual Inspection: Have a qualified technician inspect the system before each cooling season.
Coil Cleaning: Gently clean condenser coil fins with a soft brush or low-pressure water from the inside out. Straighten any bent fins.
Clear Area: Maintain at least 24 inches of clear space around the unit. Remove leaves, grass, and debris.
Fan & Motor: Inspect fan blades for cracks and balance. Lubricate fan motor per manufacturer instructions if not permanently sealed.
Electrical Check: Technician should check contactors, capacitors, and wiring for wear or corrosion.
Refrigerant Check: Technician should check system charge and for leaks.

Safety Features

High-Pressure Switch: Opens on excessively high discharge pressure. Low-Pressure Switch: Opens on excessively low suction pressure. Compressor Internal Overload: Protects against overheating. Anti-Short Cycle Timer: Prevents compressor from restarting for approximately 5 minutes after shutdown. Crankcase Heater: Activates during off cycles to prevent liquid refrigerant accumulation in compressor oil.

Care & Seasonal Shutdown

For seasonal shutdown in winter:

Turn off power to the unit at the disconnect switch.
Consider installing a waterproof cover to protect from ice and debris, but ensure it does not trap moisture and allows for ventilation.
Do not run the air conditioner when outdoor temperatures are below 55°F.

CAUTION! Never use a sharp object to clean coils. Do not use pressure washers. Keep electrical components dry.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit will not start	Power off, blown fuse/breaker, thermostat setting, safety lockout	Check disconnect and breakers. Verify thermostat is in COOL and set below room temp. Wait 5 minutes for anti-short cycle.
Compressor runs but fan does not	Fan capacitor failed, motor wiring loose, motor seized	Power off. Check capacitor with multimeter. Inspect wiring. Call for service.
Fan runs but compressor does not	Compressor capacitor, low/high pressure switch open, control wiring fault	Power off. Check compressor capacitor. Check pressure switch continuity. Verify control voltage at contactor. Call for service.
Insufficient cooling	Dirty filter/coils, low refrigerant charge, restricted airflow	Replace indoor air filter. Clean outdoor coil. Check for blocked registers. Call technician to check charge.
Unit cycles on/off frequently (short cycles)	Dirty filter/coil, overcharge/undercharge, oversized unit, faulty sensor	Clean/replace filter. Call technician to check charge and system sizing.
LED flashing a code	System fault (pressure, sensor, communication)	Count flashes, refer to fault code chart on unit panel or manual. Call for service.
Unusual noise	Loose panels, debris in fan, failing motor or compressor	Power off. Tighten access panels. Clear debris from fan. Call for service if internal noise.

Reset: For lockout conditions, turn thermostat to OFF, turn off power at disconnect for 30 seconds, then restore power and thermostat.
