Be sure to read and comprehend important cautionary
notifications in this operation manual before use

i-1 Warning: Before Using Air Dryer

In this chapter, the stated contents are especially about safety.
This Air Dryer is installed downstream of the air compressor to remove moisture. The manufacturer is not
responsible for any misuses or misapplications.

This air dryer operates with high voltage and hot surfaces during operation. In addition, this air dryer
has high speed rotating fan and motor, which can cause serious injury upon accidental contact. It is
advised that you contact the factory or SMC authorized dealer for spare parts or other servicing needs .

We strongly recommend that any one who is working with this air dryer need to read and understand the
instructions in this manual beforehand. Often, it’s necessary for the people invo lved, to r eceive training
in order to address the issues of safety and proper application.

When short period power shortage (including instantly recovered shortage) is recovered, it may take a
longer starting period than usual starting or may not start due to the protective devices.
In this case, turn off the Switch with lamp on dryer panel and wait 3 minutes. After this step, turn on the
switch to restart. When the cover panel of this unit is open, the Switch with lamp must be in the off
position, because dryer may start itself when the power supply is recovered.

Connections to a power source where the product is exposed to transient stresses exceeding
overvoltage category II (as defined in IEC60664-1).
Only connect to TN-S power distribution systems with N conductively connected to PE.
