Installation Guidelines

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

1. Location: Place on a stable, level pad (concrete or composite) with adequate clearance for airflow and service.
2. Electrical Connection: Connect power supply wiring to the unit's disconnect box per local codes and unit rating plate. Ensure proper grounding.
3. Refrigerant Lines: Connect pre-charged, insulated copper linesets from the indoor unit. Brazing with nitrogen purge is recommended.
4. Communication Wiring: Run low-voltage wiring from the communicating thermostat to the terminal block.
5. Final Check: Ensure all connections are tight, service valve caps are installed, and the unit is level.

WARNING! Installation must be performed by a qualified HVAC technician in accordance with all national and local codes. Incorrect installation can cause equipment failure, property damage, personal injury, or death.

First-Time Startup

After installation is complete, perform the following startup procedure.

1. Power Up: Turn on power at the disconnect and indoor air handler/furnace.
2. Thermostat Setup: Follow the thermostat manual to configure system type (Heat Pump), stages, and desired settings.
3. System Check: Set thermostat to COOL mode, a temperature below room temp. Verify the outdoor fan and compressor start.
4. Performance Verification: Measure superheat/subcooling, system pressures, and temperature drop across the indoor coil to confirm proper charge and operation.
5. Finalize: Explain basic operation and filter maintenance to the homeowner.

CAUTION! Do not operate the unit without the service panel securely in place. Keep the area around the unit clear of debris and vegetation.

Controls and Operation

Primary control is through a compatible communicating thermostat (e.g., American Standard AccuLink™). The outdoor unit's internal board manages compressor speed, fan operation, and system diagnostics.

Thermostat Functions: Mode selection (Cool, Heat, Auto, Off), Temperature Setpoint, Fan Control (Auto, On), Scheduling, System Status, Alerts.

Outdoor Unit Diagnostics: The control board monitors system parameters. Fault codes are indicated by flashing sequences on the onboard LED and communicated to the thermostat.

Normal Operation: In cooling mode, the variable-speed compressor will modulate to match the cooling load, maintaining steady temperature and humidity levels efficiently.

Connecting to Thermostat

For optimal performance, use a compatible communicating thermostat.

1. Turn off power to the indoor and outdoor units.
2. At the outdoor unit, locate the low-voltage terminal block (typically labeled COMM1, COMM2, etc.).
3. Run a minimum 18 AWG shielded communication cable (2-4 conductor) from the thermostat sub-base to this terminal block.
4. Connect the wires to the corresponding terminals as per the thermostat and unit installation instructions.
5. Restore power. The system will perform a self-check and establish communication.

Tip: Using the recommended thermostat unlocks full functionality, including advanced diagnostics, efficiency reports, and precise comfort control.

Maintenance Procedures

Regular maintenance ensures efficiency, longevity, and reliable operation. Always disconnect power before servicing.

1. Visual Inspection: Annually, check the unit for physical damage, corrosion, and secure electrical connections.
2. Coil Cleaning: Gently clean the outdoor coil with a soft brush or low-pressure water spray to remove dirt, leaves, and debris. Do not use a pressure washer.
3. Clearance Check: Ensure at least 24 inches of clearance on all sides (especially the coil side) and 60 inches above for proper airflow.
4. Fan Inspection: Verify the fan blades are clean, undamaged, and spin freely.
5. Professional Service: Schedule annual maintenance with a qualified technician to check refrigerant charge, electrical components, system pressures, and performance.

WARNING! Do not attempt to open the refrigerant circuit. Only EPA-certified technicians should handle refrigerant.

Safety Features

This unit includes multiple integrated safety protections:

• High/Low Pressure Switches: Shuts down the compressor if refrigerant pressure is too high or too low.
• Compressor Overload Protector: Protects the compressor from overheating.
• Anti-Short Cycle Timer: Prevents the compressor from restarting too quickly after shutdown, protecting it from damage.
• Frost Control (Heat Pump): Manages the defrost cycle to maintain heating performance in cold weather.
• Lockout Mode: In the event of a persistent fault, the system will lock out and require a manual reset or technician service.

Care & Cleaning

Keep the area around the unit clean and unobstructed.

1. Regularly remove leaves, grass clippings, and other debris from the top and sides of the unit.
2. Gently rinse the coil with a garden hose (from the inside out) during seasonal maintenance to improve airflow and efficiency.
3. Keep shrubs and plants trimmed back to maintain the recommended clearance.
4. In winter, keep the top and sides clear of snow accumulation. Do not let ice build up inside the unit.

CAUTION! Never use sharp objects to clean the coil fins. Do not operate the unit with the top grille or service panels removed.
