WARNING
If the installation configuration does not allow for
the kit to be mounted on the cased coil, the leak
mitigation kit can be installed on a nearby wall or
surface as shown in Fig. 3-9.
When the mitigation kit detects refrigerant or other operating faults, perform the following operations.
LED1 Number
of green
flashes
Fault Description Fault cause Unit response & handling method
The refrigerant sensor
communication fails.
Fails to communicate with the
refrigerant sensor for 30
consecutive seconds or the
refrigerant sensor is faulty.
LED1 of the KIT board blinks green once,
turns off the outdoor unit signal, shuts
down the compressor, forcibly outputs the
air supply signal to the gas furnace, turns
off the heating signal of the gas furnace for
5 minutes, and turns on the maximum
airflow of the gas furnace.
Contact the after-sales personnel of the
manufacturer.
Refrigerant concentration
exceeds the limit alarm
value.
A refrigerant leak has been
detected
1, maintain ventilation, cut off the outdoor
unit signal, turn off the compressor to
reduce refrigerant circulation, and avoid
open flame;
2. Force the output air supply signal,
disconnect the heating signal of the gas
furnace, and open the highest wind gear of
the gas furnace for 5 minutes until the
refrigerant concentration is reduced to a
safe value.
The refrigerant sensor is
faulty.
The refrigerant leakage sensor
determines the fault by itself,
such as the sensor's own
communication error, and the
detection concentration exceeds
the limit value.
Turn off the outdoor unit signal, shut down
the compressor, force out the air supply
signal of the gas furnace, turn off the
heating signal of the gas furnace for 5
minutes, open the maximum airflow of the
gas furnace, and replace with a new
refrigerant detection sensor.
Life reminder.
The refrigerant sensor expires.
Turn off the outdoor unit signal, shut down
the compressor, force out the air supply
signal of the gas furnace, turn off the
heating signal of the gas furnace for 5
minutes, open the maximum airflow of the
gas furnace, and replace with a new
refrigerant detection sensor.
