Pad: Install on level, stable concrete pad or approved composite stand.
Electrical: Install dedicated circuit with proper disconnect per NEC codes.
Refrigerant Lines: Connect to matching indoor unit using clean, dry copper lines.
Condensate Drain: Ensure proper drainage from indoor unit.

WARNING! Installation must be performed by qualified HVAC technician. High voltage present. Disconnect power before servicing.

First-Time Setup

After installation, perform initial startup and system check.

Power up: Turn on disconnect switch and indoor unit power.
Thermostat: Set to COOL mode, temperature below room temperature.
System check: Verify proper airflow, refrigerant charge, and electrical readings.
Test run: Allow system to run for 15 minutes, check for unusual noises or vibrations.
Register product: Complete warranty registration online or by mail.

CAUTION! Do not operate without proper refrigerant charge. Ensure all access panels are securely fastened.

Controls and Operation

System controlled by compatible thermostat. No user controls on outdoor unit.

Thermostat Operation: Set to COOL mode for cooling, AUTO for automatic fan, ON for continuous fan. Adjust temperature setpoint as needed.

System Indicators: Outdoor unit has no status lights. Refer to indoor unit or thermostat for system status.

Compressor Protection: Built-in time delay prevents short cycling (minimum 5 minutes between cycles).

Low Pressure Switch: Protects compressor from operating with insufficient refrigerant.

System Configuration

Must be matched with approved indoor units for optimal performance.

Indoor Unit Compatibility: Consult compatibility chart for approved air handlers or furnaces.
Refrigerant Lines: Use correct line size (typically 3/8" liquid, 3/4" vapor).
Thermostat: Use programmable thermostat for energy savings.
Airflow: Ensure indoor unit delivers 800-950 CFM for proper operation.

Tip: Have HVAC technician verify proper match and charge during installation.

Maintenance Procedures

Regular maintenance ensures efficiency and longevity.

Monthly: Check that unit is operating quietly and cooling properly.
Seasonal: Clean debris from around unit, trim vegetation (maintain 24" clearance).
Annual (Professional): Have qualified technician check refrigerant charge, electrical connections, clean coil, check fan motor and blades.
Winter: Cover unit during off-season to prevent debris accumulation (remove before operation).

WARNING! Disconnect all power before performing any maintenance. Do not attempt to service electrical components unless qualified.

Safety Features

High Pressure Switch: Protects against excessive pressure. Low Pressure Switch: Prevents operation with low refrigerant. Compressor Overload: Thermal protection against overheating. Time Delay: Prevents short cycling. Disconnect Requirement: NEC requires disconnect within sight of unit.

Care & Cleaning

Disconnect power before cleaning. Use soft brush or low-pressure water to clean coil fins. Never use high-pressure water which can damage fins.

CAUTION! Do not use sharp objects to clean fins. Do not use chemical cleaners unless specifically approved for HVAC coils.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit not running	Power loss, thermostat setting, time delay	Check disconnect and circuit breaker; verify thermostat settings; wait 5 minutes.
Reduced cooling	Dirty filter, dirty coil, low refrigerant	Replace air filter; clean outdoor coil; call technician for refrigerant check.
Unit cycles on/off frequently	Dirty filter, thermostat location, oversized unit	Replace filter; relocate thermostat if in direct sunlight; consult installer.
Ice on refrigerant lines	Low airflow, low refrigerant	Check/replace filter; ensure registers open; call technician.
Unusual noise	Debris in fan, loose parts, motor issue	Turn off power, remove debris; tighten access panels; call technician.
Water leakage indoors	Clogged condensate drain	Clear drain line; check drain pan.

Reset: Turn off at thermostat, turn off disconnect, wait 5 minutes, restore power.
