Installation

Unpack and inspect all components. Ensure proper location with adequate clearance.

Select location: Minimum 24 inches clearance on all sides, level concrete pad required.
Connect refrigerant lines: Braze copper lines using nitrogen purge to prevent oxidation.
Connect electrical: Follow local codes, connect to disconnect switch and thermostat.
Connect condensate drain: Install 3/4-inch PVC pipe with proper slope.
Evacuate and charge: Deep vacuum to 500 microns, charge with specified R-410A amount.

WARNING! Only qualified HVAC technicians should install this equipment. Follow all safety codes and wear appropriate PPE.

First-Time Setup

After installation, perform initial system commissioning.

Power on system: Turn on disconnect switch, verify proper voltage at unit.
Check airflow: Ensure proper airflow across indoor coil, adjust blower speed if needed.
Set thermostat: Program cooling setpoints and fan operation mode.
Verify operation: Monitor system pressures, superheat/subcooling, and temperature drop.
Test safety controls: Verify high-pressure switch, low-pressure switch, and compressor protection.

CAUTION! Do not operate without proper refrigerant charge. Overcharging or undercharging can damage compressor.

Controls and Settings

Access control board via service panel. LED indicators show system status.

Thermostat Controls: COOL/HEAT/OFF mode, FAN AUTO/ON, temperature setpoints, program schedules.

Unit Controls: Compressor protection delay (minimum 5 minutes), fan speed settings (high/medium/low), diagnostic LED codes (1-7 flashes indicate specific faults). Safety Controls: High-pressure switch (cutout at 600 psi), low-pressure switch (cutout at 30 psi), compressor thermal overload, fan cycle control.

Connecting Components

Connect to matching indoor unit (air handler or furnace), thermostat, and electrical supply.

Turn off all power at disconnect before making connections.
Match refrigerant lines: Liquid line (3/8") and suction line (3/4") with proper insulation.
Connect thermostat wires: R (24V power), C (common), Y (compressor), G (fan).
Connect power: L1 and L2 to contactor, ground to chassis.

Tip: Use nitrogen when brazing to prevent copper oxidation and system contamination.

Operating Modes

Cooling operation controlled by thermostat.

Cooling Mode: Thermostat calls for cooling, compressor and outdoor fan engage.
Fan Mode: Indoor fan operates independently of compressor.
Off Mode: System completely off, thermostat display active.
Dehumidification: Enhanced dehumidification in cooling mode with proper airflow settings.
Compressor Protection: Built-in 5-minute time delay prevents short cycling.

WARNING! Do not operate below 55°F outdoor temperature without low ambient kit. Condensate can freeze and damage coil.

Maintenance Features

Easy-access service panels for filter changes and coil cleaning. Diagnostic LEDs for troubleshooting. Service ports for pressure measurements.

Care & Cleaning

Turn off power before servicing. Clean outdoor coil annually with coil cleaner and gentle water spray. Keep area around unit clear of debris and vegetation.

CAUTION! Do not use high-pressure water spray on coil fins. Bent fins reduce efficiency. Wear eye protection when cleaning.

Troubleshooting

Symptom	Possible Cause	Corrective Action
Unit not running	Power loss, thermostat setting	Check disconnect switch, circuit breaker, thermostat batteries and settings.
Poor cooling	Dirty filter, low refrigerant	Replace air filter, check for refrigerant leaks, clean outdoor coil.
Unit cycles on/off frequently	Dirty coil, improper charge	Clean indoor/outdoor coils, check refrigerant charge and superheat.
Ice on refrigerant lines	Low airflow, low charge	Check filter, blower operation, and refrigerant charge.
Unusual noises	Loose parts, fan issues	Tighten all fasteners, check fan blade and motor bearings.
Water leakage	Clogged drain line	Clear condensate drain line, check drain pan and trap.

LED Diagnostic Codes: 1 flash - Low pressure, 2 flashes - High pressure, 3 flashes - Low voltage, 4 flashes - High voltage, 5 flashes - Compressor overload, 6 flashes - Fan fault, 7 flashes - Communication error.
