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.

to rainwater, moisture, salt water or oil.
Locations where the equipment is exposed to
dust or particles
Locations where the equipment is exposed to
flammable, combustible or explosive fumes.
Locations where the equipment is exposed to
corrosive gas or solvent.
Locations where the equipment is exposed to
direct sunlight or radiated heat.

(when there is no drain water
inside of the piping)
Locations where temperature changes rapidly.
Locations where strong electromagnetic noise
is generated.
Circumstances where static electricity is
produced or discharged through the body of the
equipment
Locations where strong high frequency shock
wave is generated
Locations where danger of thunder is apparent.
Locations where loading on vehicles, marine
vessels, and so on
Locations where altitude is higher than 2,000
meters
Circumstances where strong vibration or
impact are transmitted.
Circumstances where too much force and
weight are put on the body of the equipment
that causes it to deform.
Circumstances where not enough clearance
spaces to do maintenance

IDX-OM-K021
2-2-2 Tie Down
The air dryer should be installed on a vibration-free, stable, horizontal, flat surface.
Refer to “Chapter6 6-3 Dimensions” for the dimensions.
This model should be installed using anchor bolts (not included) to prevent shifting during a potential
earthquake.
2-2-3 Air piping
Connection to the inlet and outlet of compressed air should be made removable by using union or similar
connection.
Support the IN/OUT ports with a wrench during tightening or loosing of fittings.
Do not allow the equipment to support the weight of the piping.
Isolate the vibration generated by the compressor.
If the temperature of compressed air on the inlet side is higher than 122°F (50oC), place an aftercooler
unit after the air compressor.
If the air supply makes high pressure fluctuation (pulsation), take any countermeasures such as
installing air tank.
Clean pipes and fittings before use and select a suitable filter to prevent dust, oil or chips from entering the
air dryer, which can cause failure to the equipment.
Use pipes and fittings that can withstand the operating pressure and temperature of the compressed air.
Make sure all connections are leak-free.
Provide bypass piping to make it possible to do maintenance without stopping the air compressor.
2-2-4 Drain Tube
A polyurethane tube (3/8inch) O.D. is attached to the auto drain. The end of the tube is open to
atmosphere to let drain flow through the tube into a collector or drain pipe.
The compressed air is used to push out the drain periodically. Fix the outlet end of the tube in order to
prevent whipping action during discharge.
Install the drain tube in such a way so that no drain is trapped.
During installation, make sure the dryer does not sit on the drain tube which is at the bottom of the unit. Be
careful to avoid the dryer from crushing the tube during installation.
We recommend the bypass piping sets
available separately as accessories.

Warning
・To handle drain discharge, follow the safety guidelines such as wearing protective
goggles, apron, and gloves.
・In cases where oil is mixed in the wastewater discharged from the auto drain, the liquid
would be considered as toxic waste and treatment is necessary in accordance with local
regulations.
2-2-5 Electric Wiring
Warning
Only properly trained and qualified personnel are allowed to perform wiring
work.
Before wiring, you must disconnect the power. Do not work under any
energized conditions.
Supply power from a stable source that is free from the effect of surge.
Referring to “6-1 Specifications,”make sure to install a GFCI breaker that has
the right short circuit capacity and load capacity.
Supply power of the equipment should meet the specifications on page 6-1.
The equipment must be grounded for safety.
Do not connect ground wire to a water pipe, a gas pipe, or a lightening rod.
Do not plug too many leads into a single socket.
The customer must prepare for countermeasures of the power failure.
The dryer may not start normally at the moment of power failure.
Circuit breaker must be properly selected to meet safety standard of local
regulations.
Always be sure to connect the protective conductor first, disconnect it last in
respect to the other connections.
Be sure that the protective conductor has some additional length in respect to
the live conductors, so that it is not subject to mechanical stresses.
Be sure to install the circuit breaker correctly so that it disconnects all live
conductors and so that the operating handle can be easily accessible.
How to connect wiring
・Take off the front panel in front of the product and connect the power supply (AC230V) to the
terminal base.
・Install a Ground Fault Circuit Interrupter(GFCI) to the power supply. (Prepare by yourself)
[sensitivity of leak current: 30mA and below, Rated current 10A (IDU75E…Rated current 20A) ]
Specification of power cable
Prepare following power cable.
Power cable: 16AWG (1.25mm2), Three-cores (including the ground cable) [IDFB22E/37E], Four-cores
(including the ground cable) [IDFB55E/75E], External diameter: about 0.3inch (8mm) to 0.5inch (12mm).
Additional length of about 4inch (0.1m) is needed to wire inside of the equipment.
