Operation
Steri Clean Operation
(This function is unavailable on some models.)
When the 56℃ Steri-clean function is required,
please access in the hOn APP.
Introduction to Steri Clean
Stage 1 - Self Clean: to remove dirt away this function
freezes the evaporator with moisture in the air, and
removes dirt during the melting process.The hydrophilic
aluminium coating with smaller angel (ɑ≈5°） helps
increase water drainage efficiency.)
Stage 2 - 56℃ high temperature sterilisation: 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 any bacteria and virus inside the air
conditioner.
Stage 3 - Rapid evaporator cooling to enhance the
sterilisation performance. The foil surface is coated with
silver nano-particles which has an anti-bacterial efficiency
up to 99%.
Attention:
1.The function lasts 60-80 minutes.
2.Hot air may come out during the process when evaporator
is heated to 56℃ or maintains at 56℃ in summer.
3.This function may cause changes in room air temperature
in winter.
4.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.
HEALTH Operation
(This function is unavailable on some models.)
Press HEALTH button , the remote controller will show
and the Health function will start.
Press the HEALTH button again and the health function will be
cancelled.
UV sterilization function: it uses the c-band with the most
effective sterilization effect in ultraviolet radiation to remove
harmful micro-organisms such as bacteria in the air, which has
remarkable effects to make the air healthy.
Attention：
1. It is recommended to turn on the UV sterilization function for
1-2 hours in one day, longer time will affect the life of the UV
lamp.
2.Do not look directly at the UV lamp or touch it with your hand
when the sterilizing function is on. Please turn off the sterilizing
function before opening the panel.
3.Tinged blue light may appear near the air conditioning inlet
when the sterilizing function is on.
4.Only when the internal fan starts and health function turned
on, the UV lamp will be lighted.
SELF-CLEAN Operation
◆Functional description
the purpose of this function is to clean the evaporator.
◆Entry and exit：
If this function is needed, please select in the hOn APP.
Press SELF CLEAN button to enter this function. The
display will show "CL" on the panel of the indoor unit and
on the remote controller. Maximum running time in this
function is no more than 21 minutes. This function will exit
automatically with the " Pi " sound twice, then the unit
return to original state.During SELF CLEAN operation,
pressing the button repeatedly will not exit the process.
Press the"power" button to exit this mode.
◆ Note:
1.This function is invalid in timer / sleep mode.
2. After this mode starts, the air volume may reduce,
have no airflow, or even cold airflow blowing.
3. It is normal if the unit make some sound when the air
expands with heat and contract with cold.
4. The "CL" display time may last dif ferently on the
remote controller and panel.
5. If the outside ambient temperature is below zero, error
code "F25 "may be show up during self-cleaning
operation,which is normal protection, please turn of f the
power and restart after 10 seconds .
6. The best condition to run this mode, is when the
temperature is 20℃~27℃ and the humidity is 35％ ~60
％ indoors, the temperature is 25℃~38℃（ cooling
season）outdoors.
7.It is hard for the air to frost if the air is too dry
(humidity＜20%). and if the humidity is too high
(humidity＞70%) the condensate water may increase.
