Features at a Glance

Key components: Durable cabinet, scroll compressor, aluminized steel tubular heat exchanger, multi-speed direct-drive blower motor, electronic ignition system, integrated control board with diagnostic LED.

Installation

Unpack and inspect unit for shipping damage. Select a level, stable outdoor location with proper clearances.

1. Position unit: Place on a solid, level concrete pad or approved rooftop curb.
2. Connect ductwork: Attach supply and return ducts to unit flanges using approved methods.
3. Connect electrical: Run proper gauge wiring from disconnect to unit terminal block per local codes.
4. Connect gas line: Use approved pipe and fittings; install shut-off valve and sediment trap.
5. Connect condensate drain: Install 3/4" PVC line with proper slope away from unit.

WARNING! Installation must be performed by a qualified HVAC technician in accordance with all local codes and ordinances. Gas and electrical connections present serious hazards.

First-Time Startup & Commissioning

After installation is complete, perform the following startup procedure.

1. Verify all connections: Ensure electrical, gas, and drain lines are secure and correct.
2. Check gas pressure: Use manometer to verify correct inlet and manifold pressure per rating plate.
3. Set blower speed: Adjust motor taps for correct CFM based on cooling/heating capacity.
4. Power on: Turn on disconnect and indoor thermostat. Set to COOL mode.
5. Check operation: Verify compressor starts, blower operates, and cooling is produced.
6. Check heating: Set thermostat to HEAT mode. Verify ignition sequence and flame.
7. Measure temperatures: Check supply/return air temperature split (typically 16-22°F for cooling).

CAUTION! Do not operate without proper refrigerant charge or with blocked airflow. Ensure combustion air is unobstructed.

Controls and Settings

Primary control is via the integrated circuit board and the indoor thermostat.

Control Board (Integrated): Manages ignition sequence, blower delays, compressor lockout, and safety limits. Features a diagnostic LED that flashes error codes.

Thermostat Settings: Set system mode (HEAT/COOL/AUTO/OFF), fan mode (AUTO/ON), and desired temperature.

Blower Speed Taps: Located on blower motor. Adjust for correct airflow (CFM) based on duct static pressure and system capacity. Refer to wiring diagram for cooling/heating speed selection.

Gas Valve Adjustment: Factory set. Do not adjust unless converting to LP gas (requires conversion kit).

Connecting Components

Thermostat: Connect low-voltage wires (R, C, W, Y, G) to indoor air handler/furnace and outdoor unit terminal block.

1. Turn off all power (high and low voltage) before making connections.
2. Run 24V thermostat wires from indoor unit to outdoor unit control board.
3. Connect high-voltage wires (L1, L2) from disconnect to unit terminal block.
4. Connect ground wire to unit ground lug.
5. Connect gas line with approved pipe dope or sealant.

Tip: Label all wires before disconnecting. Verify all electrical connections are tight.

Operation

Unit operates based on signals from the indoor thermostat.

1. Cooling Cycle: Thermostat calls for cooling (Y & G energized). Outdoor fan and compressor start. Indoor blower starts after a short delay.
2. Heating Cycle: Thermostat calls for heat (W & G energized). Inducer motor starts, then hot surface igniter glows. Gas valve opens, flame is sensed. Indoor blower starts after a heat exchanger warm-up delay.
3. Fan Operation: With thermostat fan set to ON, the indoor blower runs continuously. In AUTO mode, blower cycles with heating or cooling demand.
4. Safety Controls: High-pressure switch, low-pressure switch, flame rollout switch, and high-limit switch will shut down system if unsafe conditions occur.

WARNING! Do not attempt to override safety controls. If unit locks out on a safety, diagnose and correct the root cause before resetting.

Maintenance

Regular maintenance is required for safe, efficient, and reliable operation. Perform these tasks at least annually, preferably before each cooling and heating season.

1. Inspect & Clean Air Filter: Replace disposable filter or clean permanent filter in the indoor return air duct.
2. Clean Outdoor Coil: Gently brush debris from fins. Use coil cleaner if heavily soiled. Rinse with water from the inside out.
3. Inspect & Clean Indoor Coil & Drain Pan: Check for dirt and microbial growth. Clean as needed. Ensure drain pan and line are clear.
4. Inspect Electrical Connections: Tighten any loose connections. Check for signs of overheating.
5. Inspect & Clean Burners & Heat Exchanger: Remove rust or debris. Check for cracks or corrosion.
6. Check Refrigerant Charge: Using gauges, superheat/subcooling method.
7. Check Gas Pressure & Leaks: Use manometer and leak detection solution.
8. Lubricate Motors: Most motors are permanently lubricated. Verify per specification.
9. Check & Adjust Blower Speed: Ensure CFM is correct for the application.

CAUTION! Disconnect all power before performing any maintenance. Only qualified personnel should handle refrigerant.

Care & Cleaning

Keep area around outdoor unit clear of leaves, grass, snow, and debris (minimum 24 inches clearance). Clean cabinet with mild soap and water; do not use harsh chemicals. Keep indoor vents unobstructed.

CAUTION! Do not use a pressure washer on the coil fins. Do not bend or damage fins.
