IDFA Series
If the temperature of compressed air on the inlet side is higher than 50
o
C, place an aftercooler after
the air compressor. Or, make the temperature of the place where the air compressor is installed
lower than 50
o
C.
If the air supply makes high pressure fluctuation (pulsation), take any countermeasures such as installing air
tank.
Flash the piping sufficiently in order to avoid any foreign substances such as dust, sealing tape, liquid
gasket, etc. when piping before piping connection. Foreign substances in the piping can cause
cooling failure or drainage failure.
Use pipes and fittings that have enough endurance against the operating pressure and temperature.
And connect it firmly to prevent air leakage.
Provide bypass piping to make it possible to do maintenance without stopping the air compressor.

Drain Tube
A polyurethane tube (10mm) 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.
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.
We recommend installing the bypass piping
set that is available separately as an
accessory. The part number of bypass
piping is shown in the Catalogue.
