Installation

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

Select Location: Choose a level area with adequate clearance (min 24 inches on all sides).
Set Pad: Place on a concrete pad or approved condenser pad.
Connect Refrigerant Lines: Braze lines to unit service valves using nitrogen purge.
Connect Electrical: Run high-voltage power from disconnect to unit; connect low-voltage thermostat wires.
Evacuate and Charge: Evacuate system to 500 microns, then charge with R-410A per nameplate.

WARNING! Installation must be performed by a qualified HVAC technician. Disconnect all power before servicing.

First-Time Setup

After installation, perform initial startup and system check.

Power On: Ensure disconnect switch and indoor unit are powered.
Thermostat Setup: Set thermostat to COOL mode and desired temperature.
System Check: Verify proper airflow at indoor registers, listen for unusual noises.
Measure Performance: Check superheat/subcooling per manufacturer specifications.
Test Safety Controls: Verify high-pressure and low-pressure switches function.

CAUTION! Do not operate without proper refrigerant charge. Ensure electrical connections are tight.

Controls and Settings

Primary control is via the indoor thermostat. Unit includes internal safety and operational controls.

Thermostat Settings: COOL, FAN (ON/AUTO), Temperature Setpoint.

Unit Controls: High-pressure switch, Low-pressure switch, Compressor overload, Fan delay on shutdown.

Adjustments: Fan speed may be adjustable at indoor air handler. Refrigerant charge should be set per subcooling method for fixed orifice systems or superheat for TXV systems.

Connecting Components

Connect to matched indoor coil or air handler, thermostat, and power supply.

Indoor Unit: Connect refrigerant lines (liquid and suction) between units.
Thermostat: Connect low-voltage wires (R, C, Y, G) at both indoor unit and condenser.
Power Supply: Install a dedicated disconnect switch within sight of unit. Connect line voltage (L1, L2, Ground).
Drain Line: Ensure indoor unit condensate drain is properly installed and routed.

Tip: Use correct line set size (typically 3/8" liquid, 3/4" suction for 1.5 ton). Insulate suction line.

Operation

Normal cooling operation is controlled by the thermostat.

Startup: Thermostat calls for cooling, energizing contactor in condenser.
Cooling Cycle: Compressor and condenser fan start. Refrigerant circulates, absorbing heat indoors and rejecting it outdoors.
Fan Operation: Indoor blower runs simultaneously (FAN ON AUTO) or continuously (FAN ON).
Shutdown: Thermostat satisfied, contactor de-energizes. Condenser fan may run briefly to dissipate residual heat.
Seasonal Use: For winter, cover unit to protect from debris (optional).

WARNING! Do not block airflow around unit. Keep area clear of leaves, grass, and shrubs.

Maintenance

Regular maintenance ensures efficiency and longevity. Perform annually, preferably before cooling season.

Clean Coil: Gently clean outdoor coil with water hose (no high pressure). Remove debris.
Check Electrical: Inspect wiring for damage. Tighten connections.
Inspect Fan: Ensure fan blades are clean and undamaged. Motor bearings may need lubrication (if applicable).
Check Refrigerant Lines: Inspect for leaks, ensure insulation on suction line is intact.
Clear Area: Maintain 24-inch minimum clearance around unit.

CAUTION! Turn off power at disconnect before performing any maintenance. Hire a professional for refrigerant-related service.

Regulatory Information

This unit complies with applicable U.S. safety and performance standards. R-410A refrigerant is non-ozone depleting. Proper disposal required at end of life. Manufactured by American Standard Heating & Air Conditioning. For technical support or warranty service, contact your local American Standard dealer or visit www.americanstandardair.com.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit does not start	Power off, tripped breaker, faulty thermostat	Check disconnect and breaker. Verify thermostat settings and batteries.
Unit runs but no cooling	Low refrigerant, dirty coil, faulty compressor	Check refrigerant charge. Clean outdoor coil. Contact technician.
Unit cycles on/off rapidly	Dirty filter, low refrigerant, restricted airflow	Replace indoor air filter. Check for blocked registers or ductwork.
Loud or unusual noise	Loose parts, debris in fan, failing motor	Turn off power. Tighten cabinet panels. Clear debris from fan. Inspect motor.
Ice on refrigerant lines or coil	Low airflow, low refrigerant charge	Replace air filter. Check for blocked return. Contact technician for charge check.

Reset: Turn thermostat to OFF, wait 5 minutes, then back to COOL. Reset circuit breaker if tripped.

Service: Contact a qualified American Standard dealer for repair. Do not attempt to repair refrigerant system yourself.
