refrigerant except the trained professional technicians, otherwise it may
cause personal injury.

control panel with your hands during the operation of the air conditioner,
please be careful to avoid scalding.
• In order to prevent the refrigerant from volatilizing into the atmosphere
and causing harm to the ozone layer, please recycle the refrigerant as
much as possible when it needs to be discharged during air conditioning
maintenance, and do not release it directly into the atmosphere.
• Before using the defroster, check whether the defroster operates normally,
whether the defroster vent is open, and whether the defroster vent angle is
adjusted to the best position.

the rear of the radiator before use in winter each year to prevent the sundries
in the air inlet area from being sucked into the fan, affecting the normal
operation of the fan and causing failure.
