11.13 Replacing a Main Control Module or PSU

The procedure for replacing a PSU is similar to that of replacing a main control
module. The following uses the main control module as an example.
Prerequisites
●
●
● The new module must be installed in the same slot of the original one.
Otherwise, the smart cooling product may fail to work properly.
● Before replacing the main control module, remove the cables from the module.
After replacing it, download the software and
website, and upgrade it on the display module.
Procedure
Step 1 Open the rear door and remove the air filter.
Step 2 Tap Shutdown on the home screen of the display module, and turn off the active
power switch QF1 and standby power switch QF2.
Exercise caution because the device is still energized after it is shut down on the
home screen of the display module.
Step 3 Disconnect cables from the main control module and remove the module.
