Refrigerant Sensor
Important:
• When there is a leak, the electric heater
will stop. When the refrigerant sensor
detects a refrigerant leak, the device shuts
down the compressor, external motor,
electric auxiliary heat or gas heating, and
starts the internal fan to run at the highest
speed, and the digital tube displays X.PL.
• When the main control cannot
communicate with the refrigerant sensor,
the device shuts down the compressor,
external motor, electric auxiliary heat or
gas heating, and starts the internal fan to
run at the highest speed and the digital
tube displays X.Ed.
• When the main control reads the life fault
information of the refrigerant sensor, the
device shuts down the compressor,
external motor, electric auxiliary heat or
gas heating, and starts the internal fan to
run at the highest speed, and the digital
tube displays X.EH. In this case, you need
to replace a correct sensor in time.
• When the main control reads that the
refrigerant sensor has other fault
information, the device shuts down the
compressor, external motor, electric
auxiliary heat or gas heating, and starts
the internal fan to run at the highest speed,
and the digital tube displays X.EL. X is 1/2,
1 represents the inside sensor, and 2
represents the outside sensor.
WARNING
Faulty Codes!
Failure to follow proper R-454B mitigation system
installation instructions could result in death or
serious injury or property damage.
Troubleshoot any listed faulty codes to prevent
system malfunction.
WARNING
Leak Detection System Installed!
Failure to follow instructions below could result in
death or serious injury or equipment damage.
The unit is equipped with electrically powered safety
measures and must be powered at all times after
installation, except during servicing, to detect any
leak.
• The refrigerant leakage sensor can only use the factory
model or the specified model indicated in the
corresponding manual.
• The R454B refrigerant leakage sensor must be used to
activate the refrigerant shut-off device, the alarm
device, incorporated circulation airflow, or other
emergency controls, which gives an electrical signal at
a predetermined alarm set point in response to leaked
refrigerant.
• The installation of the refrigerant leakage sensor
allows access for checking, repair, or replacement by
an authorized person. Function of the refrigerant
leakage sensor can be verified easily.
• The refrigerant leakage sensor is protected to prevent
tampering or unauthorized resetting of the pre-set
value.
• To be effective, the refrigerant leakage sensor must be
electrically powered at all times after installation, other
than when servicing.
• Refrigerant sensor must be replaced after its service
life (15 years) or if the sensor is determined to be faulty
during the service life.
NOTICE
Compressor Damage!
Failure to follow instructions below could result in the
fan to turn on to maximum and stop the compressor
resulting in the compressor failure.
If the refrigerant leakage sensor detects a refrigerant
leak, you must immediately leave the leak area and
notify a professional.
