Installation
If the installation check, as detailed in these installation instructions, does not pass successfully and cannot be resolved by calling 1-855 DAIKIN1, option 3 for further assistance, the installer must replace the furnace or modular blower with an R-32 compatible furnace or modular blower.
The Non-A2L Furnace Integration Kit was designed to support the HVAC replacement market for systems containing 1) a Furnace, Indoor Coil and Outdoor Air Conditioner or Heat Pump unit or 2) a Modular Blower, Indoor Coil and Outdoor Air Conditioner or Heat Pump unit. If either the indoor coil or outdoor unit needs to be replaced, both must be upgraded to R-32 models. If the furnace or modular Blower is still operational, it does not need to be replaced.

Operation
NON-A2L FURNACE INTEGRATION KIT is designed to read R-32 sensor concentration and utilize existing function of indoor PCBs to mitigate R-32 leakage in the unlikely event of a leak in the system. The integration kit continuously monitors the system for R-32 leaks and does not impact the normal operation of the unit when no leak/sensor fault is detected.
A simplified version of the operating principle of the integration kit is described here. For a more in-depth understanding of the integration kit’s operating principle, please contact technical service. The integration kit has two screw terminal headers – Indoor Unit (Green) and Thermostat (Black). The integration kit is connected between the thermostat and indoor unit, and it controls the traffic of signals between the thermostat and indoor unit, based on the R-32 concentration.
- R-32 Concentration detection: The integration kit is connected to a refrigerant sensor, which detects R-32 concentration. The sensor transmits the concentration, and the integration kit acts based on the concentration.
- When R-32 concentration is at a safe level, the integration kit does not interfere between the thermostat and the indoor unit. All signals are passedthrough.
- When R-32 concentration is above a certain level, or the R-32 sensor or the integration kit encounters a fault, the integration kit energises the G (fan) terminal in the indoor unit by sending a 24VAC signal.
- It also disconnects the R signal to the thermostat and/or disconnects ClimateTalk® communication, as applicable. This action will terminate all HVAC operation (Cooling or Heating) while keeping the main blower on to dissipate any refrigerant gas.
NON-A2L FURNACE INTEGRATION KIT PRE-CHECKS
The NON-A2L FURNACE INTEGRATION KIT works successfully if the following are true for the thermostat and furnace or modular blower. While these conditions are true for most thermostats and furnaces or modular blower, please consult the user manual of the thermostat and furnace or modular blower to verify.
If the thermostat, furnace, or modular blower does not conform to these common operating principles, please contact technical service to identify a compatible thermostat and/or furnace or modular blower. Do not installthe R-32 coil and/or outdoor unit if the thermostat, furnace or modular blower is not compatible.
- Standard 24VAC Thermostat: R signal of the thermostat is the source of Y1/Y2, W1/W2, G and other signals. Please verify this by disconnecting the R signal in the thermostat. If the thermostat powers off, then the thermostat is compatible.
- Non-communicating Indoor Unit: Noncommunicating indoor units must activate the blower fan within 15 seconds when a G call is presented to activate the blower fan.
- Communicating Indoor Unit: Communicating indoor units must prioritise 24VAC calls over ClimateTalk® communication and activate the lower fan within 15 seconds when a G call is presented over a 24VAC signal. This is true for all ComfortNet systems.
- Recommended: A flexible light source so that indoor unit terminals can be illuminated hands-free. It is also recommended to have sufficient light near the indoor unit terminals.

Integration Kit Work Scope
During installation of the kit:
- Disconnect wires coming from the thermostat and outdoor unit to the indoor unit.
- Connect appropriate wires from the thermostat to the integration kit’s “Thermostat” terminals.
- Use new wires to connect the integration kit’s “Indoor Unit” terminals to the indoor.
- If applicable, disconnect 4 wires for EEV coil from Indoor unit, and connect them to PCB’s “Indoor Unit” terminal per the wiring diagram provided on page 10.
- Complete the verification step.
- Verify normal operation.
- Verify mitigation function.
- Verify system returns to normal operation.
- Install and mount the kit.
Non-Communicating Outdoor Air Conditioner or Heat Pump
Perform the control R-32 leakage test for all modes of operation one by one – Cooling, Heating, Emergency heating, Constant fan and Idle. Each test will take approximately 2 to 15 minutes.
- Set the thermostat to one of the operation modes and ensure the system is running properly in that mode. Note which mode is being tested. The test sequence will need to be run again under the other modes as well.
- Locate the push button on the Non-A2L Furnace Integration Kit control and press it two times.
- The HVAC operation that was chosen should turn off (compressor, electric heat, gas heat) after a short period of time (times will vary depending on the installed system, but Electric Heat or Gas Heat should turn off within 30 seconds,s and the outdoor unit should turn off within 2 minutes).
- The indoor blower will begin to operate within 30 seconds and remain running.
- Once steps c and d have been confirmed, the test is successful. It is recommended to wait for the full 5-minute test to expire.
- Wait for the system to return to the state it was in after the first step, to confirm the system will automatically recover, and then repeat the tests on the Goodman NON-A2L Furnace Integration Kit using the other HVAC modes not previously tested.

Perform the control R-32 leakage test for all modes of operation one by one – Cooling, Heating, Emergency heating, Constant fan and Idle. Each test will take approximately 2 to 15 minutes.
- Set the thermostat to one of the operation modes and ensure the system is running properly in that mode. Note which mode is being tested. The test sequence will need to be run again under the other modes as well.
- Disconnect the R32 sensor from the Non-A2L Furnace Integration Kit control board.
- Electric heat or gas heat will turn off after a short period of time (times will vary depending on the installed system, but Electric Heat or Gas Heat should turn off within 30 seconds).
- The indoor blower will begin to operate within 30 seconds and remain running.
- Once steps C and D have been confirmed, the test is successful. Reconnect the R32 sensor.
- Wait for the system to return to the state it was in after the first step, to confirm the system will automatically recover, and then repeat the tests on the Goodman NON-A2L Furnace Integration Kit using the other HVAC modes not previously tested.
Mitigation Performance
If an R-32 leak is detected, the Non-A2L Furnace Integration Kit control will automatically enter R-32 Mitigation mode. R-32 Mitigation mode provides the same performance as seen during the test mode. The NonA2L Furnace Integration Kit will ensure all HVAC system functionality (Heating and Cooling) is off, and the indoor blower is running.
After the R-32 sensor, the Goodman NON-A2L Furnace Integration Kit no longer detects refrigerant, the system will remain in mitigation mode for an additional 5 minutes. During these 5 minutes, the red LED will change from a rapid flashing pattern to being continuously on. After 5 minutes, the Non-A2L Furnace Integration Kit will allow the system to return to normal operation, and the red LED will start a slow flashing pattern again (2 seconds on and 2 seconds off).
Before Starting Installation
Check that all the cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of ageing or continual vibration from sources such as the furnace blower or the modular blower.
