i Safety Instructions
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 involved, to receive 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 ON-OFF switch on dryer panel and wait 3 minutes. After this step, turn on the
switch to restart. Whenever open the cover panel of this unit, do not miss to turn off the ON-OFF switch,
because dryer may start itself when the power supply is recovered.
Connections to a power source where the equipment 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.
i-1-1 Hazard, Warning, and Caution Used in This Manual
This equipment is designed with the first priority on safety. However, there are some inherent risks
that cannot be eliminated. This manual classifies these risks into the following three categories
according to the severity: DANGER, WARNING and CAUTION. Read the warning statements
carefully and thoroughly understand them before operating or performing maintenance on the unit.

i Safety Instructions
i - 3
i-2-2 Hazard of Electricity
Warning
Inside of this equipment, there is a power-supplying section with high voltage
separated by the cover panel. Do not operate the equipment with the cover panel off.
i-2-3 Hazard of Hot Surface
Warning
Since this equipment has parts that become hot during operation, there is the danger
of burn-associated injuries. These parts remain hot even after power is off. Wait until
the unit has cooled down before touching.
i-2-4 Hazard of Rotating Fan Motor
Warning
Since this equipment has parts that rotate during operation, there is the danger of
injury resulting from direct contact. The fan and rotor will start/stop automatically.
Thus, do not work on them when power is on.
i-2-5 Danger of Compressed Air Circuit
Warning
Before replacing or cleaning parts, be sure to relief the pressure remained inside of the
equipment until the gauge indicates “0”. High pressure can propel object at high
velocity and cause injury.
