Connect electrical: Run 240V power to outdoor unit and 120V to indoor unit per local codes.
Connect communication wiring: Run 4-conductor thermostat cable between indoor unit and thermostat.
Connect condensate drain: Install PVC drain line from indoor unit to proper drainage.
Evacuate and charge system: Pull vacuum to 500 microns, then charge with R-410A to specified weight.

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

First-Time Setup

Power on system; configure settings via thermostat.

Power up: Turn on breakers for indoor and outdoor units.
Configure thermostat: Follow AccuLink thermostat setup wizard to select system type (4A7V8X60A1000A).
Test communication: Verify thermostat displays system status and can control both units.
Calibrate sensors: Allow system to run for 15 minutes to calibrate temperature and pressure sensors.
Set preferences: Configure temperature setpoints, schedules, and fan modes.
Test modes: Verify cooling, fan-only, and emergency heat (if equipped) operations.

CAUTION! Do not attempt first-time setup without proper HVAC training. Incorrect settings can damage equipment.

WARNING! Do not switch between heating and cooling modes rapidly. Allow 5 minutes between mode changes.

Maintenance Schedule

Regular maintenance ensures optimal performance and longevity.

Frequency	Task
Monthly	Check/clean air filter; inspect condensate drain
Seasonally	Clean outdoor coil; check refrigerant charge; inspect electrical connections
Annually	Professional maintenance: clean indoor coil, check capacitors, measure airflow, verify operation
Every 3-5 Years	Have technician perform comprehensive check: motor bearings, compressor, control board

Care & Cleaning

Turn off power before cleaning any components.

Outdoor Unit: Remove debris from around unit; clean coil with coil cleaner and gentle water spray.
Indoor Unit: Clean evaporator coil annually; ensure drain pan is clear; replace air filter regularly.
Thermostat: Clean with dry cloth only; no liquids or cleaners.
Condensate Drain: Flush with 1:1 vinegar/water solution quarterly to prevent algae.

CAUTION! Do not use pressure washer on outdoor coil. Do not bend coil fins. Keep electrical components dry.
