Installation

Unpack and inspect all components. Ensure proper location for outdoor and indoor units.

Install outdoor unit: Place on level concrete pad with proper clearance.
Install indoor unit: Mount in designated space with adequate airflow.
Connect refrigerant lines: Braze copper lines with nitrogen purge.
Connect electrical: Wire according to electrical diagram with proper disconnect.
Connect drainage: Install condensate drain line with proper slope.
Connect thermostat: Wire to control board following color coding.

WARNING! Installation must be performed by qualified HVAC technician. Refrigerant handling requires EPA certification.

First-Time Setup

Power on system; configure thermostat settings.

System startup: Turn on power at disconnect switch and circuit breaker.
Thermostat programming: Set date, time, and operating schedule.
Mode selection: Choose heating, cooling, or auto mode based on season.
Temperature settings: Set desired temperature points for comfort and efficiency.
Fan settings: Configure continuous or auto fan operation.
Test operation: Run system through complete cycle to verify performance.

CAUTION! Allow system to complete initial startup cycle before adjusting settings.

Connecting Components

Outdoor unit to indoor unit: Refrigerant lines and electrical. Thermostat to control board: Low-voltage wiring.

Turn off all power before making connections.
Connect refrigerant lines with proper flare fittings and torque.
Wire high-voltage connections with proper gauge wire and conduit.
Connect low-voltage thermostat wires following terminal designations.
Connect condensate drain with proper trap and vent.

Tip: Use nitrogen when brazing to prevent oxidation in refrigerant lines.

Operating Modes

Supports multiple operating modes for year-round comfort.

Heating Mode: Extracts heat from outdoor air for indoor heating.
Cooling Mode: Removes heat from indoor air and rejects outdoors.
Auto Mode: Automatically switches between heating and cooling.
Emergency Heat: Uses backup heat strips when heat pump efficiency drops.
Fan Only: Circulates air without heating or cooling.
Program Mode: Follows programmed schedule for energy savings.
Vacation Mode: Maintains minimum temperature during absence.

WARNING! Do not switch between heating and cooling modes rapidly; allow 5-minute delay.

Maintenance Features

Filter reminder: Programmable filter change indicator. Diagnostic codes: LED flash codes for troubleshooting. Service ports: Standard access for pressure and temperature measurements.

Care & Cleaning

Turn off power before maintenance. Clean outdoor coil with coil cleaner. Replace air filters monthly during peak season. Clean condensate drain line annually.

CAUTION! Do not use high-pressure water on electrical components. Keep outdoor unit clear of debris.

Troubleshooting

Symptom	Possible Cause	Corrective Action
System not starting	Power/thermostat	Check circuit breaker; verify thermostat settings; check disconnect switch.
No heating/cooling	Mode settings/filter	Verify correct mode selection; check air filter; ensure outdoor unit running.
Reduced airflow	Dirty filter/blockage	Replace air filter; check for blocked registers; inspect blower wheel.
Ice on outdoor unit	Low refrigerant/dirty coil	Defrost system; check refrigerant charge; clean outdoor coil.
Water leakage	Clogged drain line	Clear condensate drain line; check drain pan; verify proper slope.

Reset: Turn power off for 5 minutes then restart.
