Features at a Glance

Key components: Durable cabinet with WeatherGuard™ top, Spine Fin™ coil, Scroll compressor, High and low pressure service valves, Fan motor, Control box with contactor and capacitor.

Installation

Unpack and inspect contents. Place on a level, stable pad or slab.

1. Location: Select a well-ventilated area away from windows, shrubs, and structures that could obstruct airflow.
2. Pad/Base: Ensure a level, solid concrete pad or approved composite base.
3. Electrical Connection: Connect to dedicated 240V circuit with proper disconnect and fusing as per local codes. All wiring must be performed by a qualified technician.
4. Refrigerant Lines: Connect pre-charged, insulated refrigerant lineset from indoor unit. Brazing must be done with nitrogen purge to prevent contamination.
5. Condensate Drain: Ensure proper drainage from indoor unit is established.

WARNING! Installation and service must be performed by a qualified HVAC technician. High voltage and refrigerant under pressure can cause severe injury or death.

First-Time Setup & Startup

After installation, perform initial system startup and check.

1. Pre-Start Check: Verify all electrical connections are tight. Ensure refrigerant lines are connected, insulated, and not kinked.
2. Thermostat Setup: Install compatible thermostat. Set to OFF mode.
3. Power On: Turn on power at disconnect and indoor air handler/furnace.
4. System Start: Set thermostat to COOL mode and a temperature below room temp. The outdoor fan and compressor should engage.
5. Performance Check: Measure superheat/subcooling to verify correct refrigerant charge. Check for proper airflow at indoor registers.

CAUTION! Do not operate without proper refrigerant charge. Allow unit to sit powered off for at least 5 minutes after a shutdown before restarting.

Outdoor Unit Protections: Built-in high and low pressure switches, compressor overload protection, anti-short cycle timer (typically 5 minutes).

LED Status Light: Located on control panel. Steady ON = normal operation. Flash codes indicate specific faults (see Diagnostics section).

Connecting to Indoor Unit

This unit is designed for split-system operation with a matched American Standard indoor coil (evaporator) and air handler or furnace.

1. Ensure indoor unit is installed and refrigerant lineset is routed.
2. Connect the low-voltage control wires (typically 24V) from the indoor unit thermostat terminal to the outdoor unit's control board (Y, C, possibly O/B for heat pump versions).
3. Connect the high-voltage power lines (L1, L2, Ground) from the disconnect to the unit's contactor.
4. Connect the refrigerant lines using a proper brazing technique with nitrogen flow.

Tip: Always refer to the indoor unit's installation manual for specific wiring and compatibility details.

Operation & Maintenance

For normal operation, use the thermostat. Regular maintenance is required for efficiency and longevity.

1. Seasonal Startup: Clear any debris from around the unit. Ensure the condenser coil is clean.
2. Air Filter: Replace or clean the indoor air filter monthly during cooling season.
3. Condenser Coil: Clean the outdoor coil annually with a garden hose (power off). Spray from the inside out.
4. Inspection: Have a qualified technician perform an annual inspection, including check of refrigerant charge, electrical components, and airflow.
5. Winterization: In off-season, consider using a protective cover (ensure it allows moisture evaporation).

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

Diagnostics & Alerts

The unit's control board monitors system operation. An LED flash pattern indicates status.

• Steady ON: Normal operation, call for cooling present.
• 1 Flash: Loss of charge / Low pressure fault.
• 2 Flashes: High pressure fault.
• 3 Flashes: Low voltage or power loss.
• 4 Flashes: Compressor overload / overcurrent.
• 5 Flashes: Fault with outdoor temperature sensor (if equipped).
• Continuous Rapid Flash: Lockout mode due to repeated fault.

For any flash code, power down the system and contact a qualified service technician.

Care & Cleaning

Keep the area around the unit clear of leaves, grass, snow, and shrubs (minimum 2 feet clearance).

Cleaning the Coil: Turn power OFF. Remove the top grille (if serviceable). Use a soft brush to loosen dirt, then gently rinse the coil fins with a garden hose from the inside facing out. Do not use a pressure washer.

CAUTION! Do not bend or damage the delicate aluminum fins on the coil. Do not use chemical cleaners unless specified by American Standard.
