CAUTION
To avoid deformation of the filter, do not use fire or a burning appliance to dry the filter.
If the filter is dirty, use a soft brush and neutral detergent to clean it, then shake off the water and dry it in
a cool place.
Non-professionals should not disassemble, replace or repair the filter.
4
Reinstall the filter.
5
Reinstall and close the air inlet grille by following steps 1 and 2 above in reverse.
Maintenance
During in-depth maintenance, the air conditioner should be cleaned and maintained by
professional technicians every 2 to 3 years.
For the indoor unit 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 outdoor unit master unit for preheating more than
12 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.
CAUTION
Before the air conditioner is idle for a long time, the internal components of the outdoor units 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 outdoor unit and indoor unit after long periods of use to see if
they are blocked; if an inlet/outlet is blocked, clean it immediately.
Wooden buildings, newly renovated houses, and frequent use ofdisinfectants may contain acidic
components in the air, such as formic acid, acetic acid, and hypochlorous acid, which can corrode copper
pipes and solder joints, leading to refrigerant leaks.
Factories, chemical plants, livestock farms, vegetable markets, sewage pits, and other environments may
contain sulfides, acid gases such as sulfur dioxide, ammonia, and chlorides in the air.
These places may cause corrosion to the copper pipes and joints of the indoor unit, and it is necessary to
have a professional inspection every six months.
