Features at a Glance

Key components: Outdoor condenser unit with variable-speed compressor, AccuLink communication module, Thermostat interface, Refrigerant lines, Electrical disconnect.

Installation

Unpack and inspect all components. Select appropriate location for outdoor unit.

1. Position outdoor unit: Place on level concrete pad or mounting brackets, minimum 24 inches clearance on all sides.
2. Connect refrigerant lines: Braze copper lines between indoor and outdoor units following EPA guidelines.
3. Connect electrical: Run 240V power to disconnect box, then to unit terminals (L1, L2, Ground).
4. Connect communication wiring: Run 4-conductor cable between outdoor unit and indoor AccuLink interface.
5. Connect thermostat wiring: Run cable from indoor unit to thermostat location.
6. Evacuate and charge system: Pull vacuum to 500 microns, charge with R-410A per nameplate specifications.

WARNING! Installation must be performed by qualified HVAC technician. High voltage present. Refrigerant handling requires EPA certification.

First-Time Setup

Power on system; configure through thermostat interface.

1. System initialization: Power on outdoor unit and indoor handler; wait for communication handshake (approximately 2 minutes).
2. Configure thermostat: Set language, date/time, and preferences through thermostat menu.
3. Calibrate zoning: If installed, run zoning calibration through thermostat zoning menu.
4. Set comfort settings: Program desired temperatures for different times of day.
5. Test operation: Run system in cooling mode to verify proper function.

CAUTION! Do not attempt setup without proper training. Incorrect settings may damage equipment.

Connecting Thermostat & Zoning

AccuLink system requires compatible thermostat and optional zoning panel.

1. Turn off power at disconnect before wiring.
2. Connect thermostat: Use 8-conductor cable to terminals (R, C, Y1, Y2, G, O/B, ACC+, ACC-).
3. Connect zoning panel: If using zoning, connect zone dampers and zone sensors to zoning panel.
4. Connect outdoor unit: Ensure communication wiring (4-conductor) is properly terminated.
5. Power on and test communication.

Tip: Use shielded cable for communication wires and maintain separation from power cables.

Operating Modes

System offers multiple operating modes for comfort and efficiency.

1. Cooling Mode: Maintains set temperature with variable-speed adjustment.
2. Dehumidification: Enhanced moisture removal in high humidity conditions.
3. Fan Only: Circulates air without cooling.
4. Auto Mode: Automatically switches between heating and cooling based on setpoints.
5. Zoning Operation: Different temperatures in different zones simultaneously.
6. Vacation Mode: Maintains energy-saving temperature while away.
7. Smart Recovery: Learns system performance to reach setpoints at scheduled times.

WARNING! Do not set temperature below 68°F in cooling mode for extended periods to prevent coil freezing.

Maintenance Schedule

Regular maintenance ensures optimal performance and longevity.

Care & Cleaning

Turn off power before any cleaning. Keep area around outdoor unit clear of debris.

1. Outdoor unit: Remove leaves and debris from coil fins using soft brush or vacuum.
2. Condensate drain: Pour 1 cup vinegar through drain line annually to prevent clogs.
3. Electrical connections: Inspect for corrosion; clean with electrical contact cleaner if needed.
4. Cabinet: Wash with mild detergent and water; avoid high-pressure spray.

CAUTION! Do not bend coil fins. Do not use harsh chemicals. Keep electrical components dry.
