05.04. Maintenance
1. During in-depth maintenance, the air conditioner should be cleaned and maintained by rofessional technicians every
2 to 3 years.
2. 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.
3. Preheat the unit in advance.
When the heating season comes, power on the outdoor Unit 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.
4. Complete the following steps before the air conditioner is put out of use for a long period:
• 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 nd have negative health
effects.
• 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.
• 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 customer service 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.
