Cleaning Air Outlets and Exterior Panels
Maintenance

Wipe the air outlet and panel with a dry cloth.
If a stain is hard to remove, clean it with clean water or neutral detergent.
Do not use gasoline, benzene, volatile agents, decontamination powder or liquid insecticides. Otherwise, the
air outlet or panel may become discolored or deformed.
Do not expose the inside of the IDU to moisture, as it may result in electric shock or fire.
When cleaning the louver with water, do not scrub it violently.
If the air conditioner is used without an air filter, the accumulation of dust in the air conditioner will often
cause malfunctions due to the failure to remove dust from the indoor air.
Caution
During in-depth maintenance, the air conditioner should be cleaned and maintained by
professional technicians every 2 to 3 years.
For the IDU in constant speed mode, the primary efficiency filter is usually cleaned every three
months.
When operating in a dusty environment, the air flow and capacity of the filter will decrease. The filter
may even become blocked, and the air conditioner performance and indoor air compromised.
Preheat the unit in advance.
When the heating season comes, power on the ODU master unit for preheating more than 4 hours
before use. The preheating time depends on the weather temperature. This can make the air conditioner
operate more stably and help the refrigeration oil in the air conditioner compressor to maintain the best
lubrication state, which can prolong the service life of the compressor.
Complete the following steps before the air conditioner is put out of use for a long period:
①
If the air conditioner is not in use for a long time due to seasonal changes, keep the unit running for 4-5
hours in fan mode until the unit becomes completely dry. Otherwise, it may grow mold indoors and
have negative health effects.
①
When not in use for a long time, power off or unplug the power plug to reduce standby power
consumption, and wipe the wireless remote controller with a clean soft dry cloth and remove the
battery.
①
Turn on the power switch 12 hours before using the air conditioner again. In addition, in seasons
when air conditioners are frequently used, keep the power switch on. Otherwise, failures may occur.
Before the air conditioner is idle for a long time, the internal components of the ODUs should be checked
and cleaned regularly. For more details, please contact the local air conditioner customer service center or
special technical service department.
Check the return air inlet and outlet of the ODU and IDU after long periods of use to see if they are blocked;
if an inlet/outlet is blocked, clean it immediately.
