Before starting the unit again, you should:
Clean or replace the air filter.
Clean the heat exchanger.
Make sure the drain pipe for drain pan of heat exchanger is
clean; if not, wash it.
Remove air from the water system.
If the unit is not to be used in winter, drain the water system
when appropriate. Otherwise, the water in the system may
freeze, thus causing damage to the unit, or leading to water
leakage, electric shock or damage to furniture.
Start the unit after it has not been used for a long
time
Leave the unit unused for a long period
1) Start and stop
Start or stop the unit using the wired controller or centralized controller.
