NOTICE
The R32 refrigerant leakage sensor is a semiconductor detector which may
incorrectly detect substances other than R32 refrigerant. Avoid using chemical
substances (e.g. organic solvents, hair spray, paint) in high concentrations, in the
close proximity of the indoor unit because this may cause misdetection of the R32
refrigerant leakage sensor.
INFORMATION
Lifetime of the sensor is 10 years. The user interface displays error "
CH-05
" 6 months
before the end of the sensor lifetime and error "
CH-02
" after the end of the sensor
lifetime. For more information refer to the reference guide of the user interface and
contact you dealer.
