Evaporative Air Cooler
21
E3
”E3” flashing indicates, the voltage supply to air cooler is under-voltage, (lower than 140V or phase
failure). Please break the power off, and check the power supply.
E8
"E8" flashing indicates, the wall controllers can’t receive the signal from air cooler, tr y to pull out the
signal line, and re-plug, pay attention to the good connection on communication interface.
E9
“E9” flashing indicates, the failure in water supply, if the water supply action can’t be finished within 15
minutes, please turn the COOL function off, and check the water supply system.
Restart the COOL function, the machine will add water again, that can solve the water failure caused
by small water flow.
Maintenance
(1). It is to be noted to change the water while the cooler is in work to avoid incrustation.
(2). The filter pads should be cleaned more often to keep the cooling efficient. Do not use wat er above 40
℃
.
Banister brush can be used softly to scrub away the dust on the pads.
(3)The water supply should be shut off to avoid bacteria as well as cold weather. It is also recommended
covering to protect the cooler in some dusty and snowy cities.
Cleaning:
(1).All the type of this series has the function of auto timing cleaning. (the cooler will operates auto cleaning
function after accumulative 8 hours under persistence power supply.)
(2).We recommend to clean the pad every month to keep the cooler under best condition.
