Connect Electrical: Run dedicated circuit from main panel to disconnect box, then to unit. Follow local codes.
Connect Communication Wiring: Run 4-conductor thermostat cable between outdoor unit, indoor unit, and thermostat.
Connect Condensate Drain: Ensure proper drainage from indoor coil to prevent water damage.
Evacuate and Charge: Evacuate system to 500 microns, then charge with specified amount of R-410A.

WARNING! Installation must be performed by a qualified HVAC technician. Incorrect installation can cause property damage, personal injury, or death. Disconnect all power before servicing.

First-Time Setup

Power on system; configure communicating network.

Power Up: Turn on power at disconnect box and indoor unit.
System Handshake: The AccuLink™ thermostat will automatically detect and configure the outdoor and indoor units.
Configure Thermostat: Set date, time, desired temperature schedules, and system preferences (Cool, Heat, Auto, Off).
Test Operation: Run system in cooling and heating modes to verify correct operation and airflow.
Check Pressures & Temperatures: Verify refrigerant pressures and temperature drop/rise are within specifications.

CAUTION! Do not attempt first-time setup without proper training. System requires correct refrigerant charge and airflow for safe and efficient operation.

Controls and Settings

Primary control is through the AccuLink™ thermostat. Outdoor unit has a diagnostic LED and a service test mode.

AccuLink™ Thermostat: POWER, SYSTEM (Off, Heat, Cool, Auto), FAN (Auto, On), TEMPERATURE adjustment, MENU, HOLD, SCHEDULE, FILTER reminder reset, DIAGNOSTICS menu.

Outdoor Unit LED: Steady Green = Normal operation. Flashing Codes indicate specific faults (e.g., 1 flash = Communication error, 2 flashes = High Pressure, 3 flashes = Low Pressure).

Service Test Mode: Activated via thermostat or by jumping test terminals on the control board. Allows manual operation of compressor and fan for diagnostics.

Configuration DIP Switches: Located on control board for optional settings (e.g., thermostat type, fan delay).

Connecting Components

System requires connection between outdoor unit, indoor unit (air handler/furnace), and thermostat.

Turn off all power at disconnect box and indoor unit.
Run high-voltage power wiring (L1, L2, Ground) to outdoor unit.
Run 4-conductor communication cable (R, C, 1, 2) between all components.
Connect refrigerant lines (Liquid and Vapor) using flare or braze fittings.
Connect condensate drain line from indoor coil to suitable drain.
Restore power. The system will perform an automatic communication check.

Tip: Use wire nuts and conduit as required by code. Label all wires for future service. Ensure communication wiring is not run parallel to high-voltage lines to avoid interference.

Operating the System

Use the AccuLink™ thermostat for daily operation.

Set Mode: Select HEAT, COOL, AUTO, or OFF.
Set Temperature: Use up/down arrows to set desired temperature. In AUTO mode, set both heating and cooling setpoints.
Set Fan: Select AUTO (fan runs only when heating/cooling) or ON (fan runs continuously).
Schedule Programming: Use SCHEDULE menu to set different temperatures for different times of day (Wake, Leave, Return, Sleep).
Temporary Override: Press HOLD to temporarily maintain current settings, overriding the schedule.
Filter Reminder: The thermostat will alert you when it's time to check/replace the air filter. Reset the reminder after maintenance.

WARNING! Do not set thermostat temperature extremely low in cooling or extremely high in heating, as this can cause the system to run continuously and potentially freeze the coil or overheat.

Maintenance Schedule

Regular maintenance is required for optimal performance and warranty compliance.

Frequency	Task	Description
Monthly	Check/Replace Air Filter	Inspect indoor air filter. Clean or replace if dirty.
Annually (Spring)	Pre-Cooling Season Check	Performed by a qualified technician: Clean outdoor coil, check refrigerant charge, inspect electrical connections, check system controls.
Annually (Fall)	Pre-Heating Season Check	Performed by a qualified technician: Inspect heating components (if heat pump), check defrost cycle, verify airflow.
As Needed	Clear Area	Keep area around outdoor unit free of leaves, grass, snow (at least 2 feet clear).

Care & Cleaning

Turn off power before any cleaning.

Outdoor Coil: Gently clean with a soft brush or low-pressure water from the inside out. Do not use a high-pressure washer.
Outdoor Unit Fins: Straighten any bent fins with a fin comb.
Indoor Coil & Drain Pan: Access may require removing panels. Vacuum coil gently. Pour a cup of diluted bleach or vinegar through the drain line to prevent algae.
Cabinet: Wipe exterior with a damp cloth. Do not use harsh chemicals.

CAUTION! Never use water to clean electrical components. Do not operate the system without the service panels securely in place.

Troubleshooting

Symptom	Possible Cause	Corrective Action
System not turning on	Power loss, tripped breaker, blown fuse	Check disconnect box and main panel. Reset breaker or replace fuse. Ensure thermostat batteries (if any) are fresh.
No cooling/heating	Thermostat setting, dirty filter, closed registers	Verify thermostat mode and setpoint. Check/replace air filter. Ensure supply and return vents are open and unblocked.
Reduced airflow	Dirty filter, blocked coil, failing blower motor	Replace filter. Inspect indoor coil for dirt. Listen for unusual blower noises; contact technician.
Unit cycles on/off frequently (short cycling)	Dirty filter, low refrigerant, faulty sensor	Replace filter. Check for ice on lines. Flashing LED code indicates need for professional service.
Ice on outdoor or indoor unit	Low airflow, low refrigerant charge	Turn system OFF. Check/replace filter. Allow ice to melt completely. If problem recurs, call for service.
Unusual noises (grinding, squealing)	Loose parts, failing motor or compressor	Turn system OFF immediately. Check for loose panels or debris in fan. Contact technician.
Water leakage indoors	Clogged condensate drain	Turn system OFF. Locate drain line and clear blockage. Use wet/dry vacuum on drain port.
Diagnostic LED flashing	System fault detected	Count the flashes and refer to the fault code chart on the inside of the service panel. Call for service.

Reset: Turning power OFF at the disconnect for 5 minutes and then back ON may clear transient faults.

Service: For all complex issues, flashing LED codes, or refrigerant-related problems, contact a qualified American Standard dealer. 1-800-628-4516; www.americanstandard.com
