Installation

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

Location: Place on level concrete pad or approved mounting system, away from obstructions.
Clearances: Maintain minimum 24 inches clearance on all sides, 48 inches above.
Electrical: Connect to dedicated circuit with proper disconnect and fusing as per local codes.
Refrigerant Lines: Connect pre-charged lines to matching indoor coil; ensure tight, leak-free connections.
Condensate Drain: Ensure indoor unit drain line is properly installed and unobstructed.

WARNING! Installation must be performed by a qualified HVAC technician. Improper installation can cause injury, equipment damage, or void warranty.

First-Time Startup

After installation, perform system startup and check.

Power On: Ensure electrical disconnect is ON and indoor thermostat is set to OFF.
System Check: Verify refrigerant charge using superheat/subcooling method.
Thermostat Setup: Set thermostat to COOL mode, temperature below room temp to initiate cooling.
Operation Verification: Listen for normal compressor and fan operation; check for adequate airflow and cooling at indoor vents.
Safety Controls: Verify high and low-pressure switches, compressor overload protection are functional.

CAUTION! Do not operate without proper refrigerant charge. Allow unit to stabilize for 10-15 minutes before taking measurements.

Connecting to Indoor Unit

This unit must be matched with an approved American Standard indoor coil or furnace.

Turn off all power to indoor and outdoor units.
Connect refrigerant lines using flare or braze fittings as per installation instructions.
Connect low-voltage control wires (typically 24V) between outdoor unit and indoor thermostat.
Connect line-voltage power supply to unit disconnect.
Evacuate and charge system according to manufacturer specifications.

Tip: Refer to the indoor unit installation manual for specific compatibility and wiring details.

Operation

Normal operation is controlled by the indoor thermostat.

Set thermostat to COOL mode and desired temperature.
Set fan to AUTO (cycles with compressor) or ON (continuous).
Outdoor unit fan and compressor will engage when cooling is demanded.
Unit will cycle off when set temperature is reached.
For best efficiency, keep thermostat set at constant temperature during cooling season.

WARNING! Do not attempt to operate unit if unusual noises, smoke, or burning smells are detected. Turn off power immediately and contact a technician.

Maintenance

Regular maintenance ensures efficiency and longevity.

Monthly: Visually inspect outdoor unit for debris, damage, or obstruction.
Seasonal (Spring): Clean outdoor coil with gentle water spray (power off). Check refrigerant lines for insulation damage.
Annual (Professional): Have qualified technician check refrigerant charge, electrical connections, compressor operation, and clean indoor coil if accessible.
Filter: Replace indoor air filter every 1-3 months depending on usage.

CAUTION! Always disconnect power before performing any maintenance. Do not use pressure washer on coils.
