7) For remote operation, the product is turned on/off using the external switch while the yellow switch
(main unit / remote selector switch) is turned ON. Allow at least 3 minutes before restarting remote

being stopped, the protection circuit will be activated, and the dryer will not start.
When operation does not start, restart it referring to the Chapter 6 Troubleshooting.
4.5 Check points before restart
When starting operation, check the following points. Immediately stop operation if any abnormalities
occur. Turn on the black switch (stop) and then shut off the power supply breaker.
There should be no leakage of compressed air.
Compressed air pressure, temperature, flow rate and ambient temperature are within the
specifications of the product.
Confirm that drain comes out of the drain tube.
The evaporation thermometer is in the green area.
Drain should not be exhausted from the compressed air outlet of the air dryer.
There should be no abnormality with noise or vibration or odor from the product.
Cooling water flows.
4.6 Cautions when the product is shut down for an
extended period of time
When the product is not used for a period longer than 24 hours, turn on the black switch (stop) or turn
off the power supply. It is recommended to discharge the residual pressure and drain from the
compressed air piping.
The residual drainage in the air dryer may splash over the outlet when the operation is re-started, so it
is recommended to install a filter on the outlet of the air dryer.
Stop feeding water to the cooling water pipes and discharge the water from the water release plug.
