2 How to Perform a Test Run
Configuring the Outdoor Unit DIP Switches (Check)
CAUTION
z
Before accessing the DIP switches, make sure that all of the LEDs on the PCB are
off after the power source is turned off. Attempting to access the DIP switches with
any LED lit can result in an electrical shock due to electricity remaining in the
circuit.
Be sure to check the DIP switch settings even if it is not necessary to change them from the factory
default settings.
After changing any DIP switch setting or connector, you have to turn the power off and on again for the
new setting to take effect.
When you want to reset the outdoor unit power supply, turn off the power and make sure that none of the
LEDs on the PCB are lit before turning the power on again. An attempt to reset the power supply with a
LED lit may fail due to electricity remaining in the circuit.
