Operation
Steri Clean Operation
If 56℃ Stericleaning function is needed, please
check in hOn APP.
Introduction to Steri Clean
1st-stage: Self Clean to remove dirt away (It freezes the
evaporator with moisture in the air, and removes away dirt
in melting. The hydrophilic aluminum coating with smaller
angel (ɑ≈5°） helps increase water drainage efficiency.)
2nd-stage: 56℃ high temperature sterilization (It utilizes
smart temperature monitoring and frequency control
technology to adjust the compressor operation, so that we
maintain the evaporator temperature at high temperature
for over 30mins to kill bacteria and virus inside the air
conditioner.)
3rd-stage: Rapid evaporator cooling to enhance the
sterilization performance. The foil surface is coated with
silver nanoparticles whose anti-bacterial efficiency is up
to 99%.
Reminder:
The function lasts 60-80 minutes.
Hot air may come out during the process when
evaporator is heated to 56℃ or maintains at 56℃ in summer.
The function may result in the changes of room air
temperature in winter.
When outdoor ambient temperature is above 36℃,
the function cannot be performed. Instead, Self Clean
function will be turned on and lasts 21mins when Steri
Clean is turned on.

SELF-CLEAN Operation
◆Functional description
the purpose of this function is to clean the evaporator.
◆Entry and exit：
If this function is needed, please check in hOn APP.
Press SELF CLEAN button to enter this function, then
it will display "CL" on the panel of the indoor unit and also
on the remote controller. Maximum running time not more
than 21 minutes, this function will exit automatically with the
" Pi " sound twice, then the unit return to original state.
Under operation process of SELF CLEAN, press the button
repeatedly is invalid and cannot exit, please press the
"power" button or swift to other mode to exit.
◆ Note:
1.This function is invalid in timer / sleep mode.
2.After this mode starts, the air volume may reduce or
even have no airflow,or even cold airflow blowing.
3.It is normal if the unit make some sound like expand with
heat and contract with cold.
4. The "CL" display time may last differently on the remote
controller and panel.
5.If the outside ambient temperature below zero, error
code "F25 "may be occurred during self-cleaning operation ,
which is normal protection, please turn off the power
and to restart after 10 seconds .
6.The best condition to run this mode: the temperature is
20℃~27℃ and the humidity is 35％~60％ in the door,
the temperature is 25℃~38℃（cooling season）out the
door.
7.It is hard to frost if the air is too dry(humidity＜20%). and
if the humidity is too high(humidity＞70%).the condensate
water may increase, which may move away some frost.
