Pad: Place on a solid, level concrete, composite, or plastic pad.
Ductwork Connection: Connect supply and return ducts securely. Seal all joints with approved duct sealant.
Electrical Connection: Connect line voltage (208/230V, 1-phase) to unit disconnect. Connect low-voltage thermostat wiring to control board.
Gas Connection: Connect gas supply line using approved pipe and fittings. Check for leaks with soap solution.
Condensate Drain: Connect PVC drain line from unit to an approved drain location.

WARNING! Installation must be performed by a qualified HVAC technician in accordance with all local codes and the National Fuel Gas Code (NFPA 54) and National Electrical Code (NFPA 70).

First-Time Setup & Startup

After installation, perform initial startup and system check.

Pre-Start Check: Ensure all electrical, gas, and duct connections are secure. Verify correct refrigerant charge.
Power On: Turn on electrical disconnect. Set thermostat to OFF.
Thermostat Configuration: Program thermostat for system type (Gas Heat / Electric Cool) and stages.
Test Mode: Initiate a test cycle for cooling and heating to verify operation. Check airflow at registers.
Final Settings: Set desired fan mode (AUTO or ON) and program temperature schedules.

CAUTION! Do not operate the unit without a properly sized and installed filter. Do not bypass safety devices.

Controls and Settings

Primary control is via a compatible thermostat. Unit control board provides diagnostic LEDs.

Thermostat: Use a compatible 2-stage cooling / 1-stage heat thermostat. Settings include SYSTEM (OFF, HEAT, COOL, AUTO), FAN (AUTO, ON), and temperature setpoints.

Unit Control Board: Located in the control compartment. LED indicators flash codes for normal operation and fault conditions (refer to fault code chart on inside panel).

Blower Speed Taps: Cooling and heating blower speeds are set at factory but can be adjusted by a technician for optimal airflow via taps on the control board.

Gas Valve: Single-stage operation. Gas pressure adjustment requires a qualified technician.

Connecting to Thermostat & Ductwork

Low-voltage thermostat connection and ductwork sealing are critical.

Turn off all power to the unit at the disconnect.
Remove control panel access door.
Connect thermostat wires (R, C, Y1, Y2, W1, G) to the corresponding terminals on the unit's low-voltage terminal strip.
Route low-voltage wire through the provided grommet and secure the access panel.
For ductwork, use rigid metal or approved flexible duct. Insulate ducts in unconditioned spaces.
Seal all duct joints with mastic or UL 181 approved tape.

Tip: Use a 5-conductor (minimum) thermostat cable for full functionality. Label wires at both ends.

Operation Modes

Unit operates in Cooling, Heating, or Fan Only modes based on thermostat signal.

Cooling Mode (Two-Stage): On a call for cooling, thermostat energizes Y1. If cooling demand persists, Y2 is energized for high-stage cooling. Variable-speed blower adjusts airflow.
Heating Mode (Single-Stage): On a call for heat, thermostat energizes W1. Gas valve opens, igniter activates, and blower starts after a warm-up delay.
Fan Only Mode: Thermostat energizes G terminal. Blower runs continuously at a low speed for air circulation.
Automatic Mode: Thermostat controls system selection (Heat or Cool) based on room temperature vs. setpoints.

WARNING! Do not switch system modes rapidly. Allow 5 minutes between cycles for system pressure equalization.

Maintenance Schedule

Regular maintenance ensures efficiency and longevity. Some tasks require a qualified technician.

Task	Frequency	Notes
Inspect/Replace Air Filter	Monthly (During peak use)	Use same size and type
Visual Inspection	Seasonally	Check for debris, corrosion, damaged insulation
Clean Outdoor Coil	Annually (Spring)	Turn off power, use soft brush and coil cleaner
Check Condensate Drain	Annually	Clear any algae or debris
Inspect Electrical Connections	Annually (By Technician)	Check tightness, signs of overheating
Check Refrigerant Charge	Annually (By Technician)	Verify with gauges
Inspect Burner & Heat Exchanger	Annually (By Technician)	Check for corrosion and proper flame
Lubricate Motors (if required)	As per Technician	Most motors are permanently sealed

Care & Cleaning

Turn off power at the disconnect before any cleaning.

Exterior: Wash cabinet with mild soap and water. Rinse thoroughly. Do not use high-pressure water.
Coils: Clean outdoor coil with a commercial coil cleaner and soft brush. Straighten any bent fins with a fin comb.
Area Around Unit: Keep a 24-inch clearance from shrubs, leaves, and debris.
Internal Components: Do not spray water inside the unit. Vacuum loose debris from the interior carefully.

CAUTION! Do not clean the heat exchanger or burners yourself. This must be done by a qualified technician.

Troubleshooting

IMPORTANT: Only basic troubleshooting should be performed by the homeowner. For complex issues or gas/electrical problems, contact a qualified HVAC technician.

Symptom	Possible Cause	Corrective Action
Unit does not start	Power off, tripped breaker, thermostat setting	Check disconnect and breaker. Verify thermostat is set to HEAT or COOL above/below room temp.
No heat	Gas valve off, pilot/ignition issue, dirty filter	Ensure gas valve is on. Check and replace filter. If problem persists, call for service.
No cooling	Dirty filter, blocked coil, thermostat setting	Replace filter. Clear debris from outdoor coil. Verify thermostat set to COOL.
Unit cycles on/off frequently (short cycles)	Dirty filter, blocked airflow, faulty sensor	Replace filter. Ensure registers are open and not blocked. May require technician.
Blower runs continuously	Thermostat fan setting on ON	Set thermostat fan setting to AUTO.
Unusual noise (rattling, buzzing)	Loose panel, debris in blower, failing motor	Turn off power. Check and tighten access panels. Remove visible debris. Call for service if noise continues.
Ice on refrigerant lines or coil	Dirty filter, low refrigerant, low airflow	Turn system OFF. Replace filter. Allow ice to melt completely. If problem recurs, call for service.
LED fault code flashing	System fault detected	Count flashes, refer to fault code chart on unit panel. Note code and call for service.

Reset: For lockout conditions, turn off power at the disconnect for 30 seconds, then restore power.
