5.2 Troubleshooting

CA UTION

Do not maintain or replace outdoor units during thunderstorms. Otherwise, your

personal safety will be in danger.

NO TICE

● You are not advised to maintain or replace outdoor units in rainy days. If

unavoidable, take protective measures to prevent water from entering the

outdoor unit.

● When opening the electric control box cover, clear water from the cover.
● Certain circuits in the smart cooling product have lethal voltages. Only

professional technicians are allowed to perform maintenance.

● Exercise caution during troubleshooting with power on.
● If jumpers are used for troubleshooting, always remove them after

troubleshooting. Connected jumpers may affect control functions and damage

equipment.
