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 (50
o
C), 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.

Turn on the breaker of the main power supply. Then, turn ON the ON/OFF switch. The lamp will light up. Few minutes later, the cooling fan will rotate and hot air will be exhausted from
the ventilation grille. Location of the ventilation grille: Right Side
Open the IN/Out side valve slowly. Make sure the bypass valve is completely closed. Confirm there
are no air leaks.
Depending on the condition of compressed air or ambient temperature, the cooling fan sometimes
alternates between start/stop at the beginning. Then, the refrigerant compressor will start and the pointer of the evaporating temperature will indicate in the green zone. If the pointer indicates higher than the green zone, refer to Chapter 5 Troubleshooting.
After running for a while, moisture will be discharging from the drain tube automatically.
Caution
Avoid frequent On/Off operation, which may cause problems. The auto drain used for the equipment has a structure that closes the valve with air
pressure higher than 22psi0.15MPa. Therefore, until the pressure increase, air will be emitted form the drain outlet at the begining of opening the IN side valve. Keep in mind that sometime the pressure cannot increase enough with air compressor that has low dischage flow rate. Avoid using this product under the condition which has sudden pressure/flow rate changes. Otherwise, drain (condensed water) may flow out to the secondary piping.

Maintenance of the air dryer should only be carried out by someone with sufficient knowledge and
experience of air dryers and related equipment.
Before carrying out maintenance, the important warnings in this manual must be thoroughly read and
understood.
When replacing or cleaning parts of the air dryer, be sure to remove the compressed air pressure inside
the air dryer to “0”. Never remove the case assembly when the air dryer is operated or air pressure remains inside. It is extremely dangerous if compressed air pressure remains inside the air dryer, as parts may come flying off at speed when loosened, or other unexpected accidents.
This product has parts that become hot during operation and a power supply with high voltage applied.
There is a risk of burns due to heat or electrification by high voltage. Even when operation is shut down after switching off the air dryer’s illuminated light, there are also charging lines. When working on the charged sections, be sure to switch off the earth leakage breaker installed before starting work.
As some parts of the air dryer will remain hot, there is a risk of burns due to residual heat after the
power is switched off. So do not carry out replacement work until the temperature of these parts has fallen to 50 or less. Wait for about 10 to 15 minutes as a guide.
When carrying out maintenance work on the auto drain strainer and auto drain, there is a risk of
touching the drain fluid during work. Please follow the safety procedure for operators specified by customer.Example: carry out work wearing safety glasses, apron and gloves to prevent discharged fluid from touching the human body.
Use neutral detergent solution to clean parts such as the auto drain strainer and auto drain. Never
use solvent such as thinner.
When removing the outer casing panel or case assembly of the auto drain, wear gloves to prevent
injuries.
How to clean and replace the case assembly.

IDFB22E / 37E / 55E / 75E
Compressed Air Circuit
Humid hot air entering air dryer is cooled in the cooler. At this time , the condensate is separated from the air by the drain separator and automatically discharged. The dry air is heated by the re-heater until it gets about the same temperature as that of ambient air. It is then discharged from air dryer outlet.
Refrigerant Circuit
The Fluorocarbon charged in the refrigerant circuit is compressed by the compressor and cooled by the condenser to become liquid. Then, going through the capillary tube, the refrigerant pressure and temperature (evaporating temperature) decreased rapidly. Passing through the cooler part, it draws heat from the hot compressed air and intensely boils. Finally, it is sucked into the compressor again. The hot gas bypass valve opens to prevent compressor from freezing when compressed air is too cold.

The heat of humid hot air entering to the air drier enters to the cooler and is cooled and dehumidified by cold fleon, separating the moisture. The cold air is released from the air dryer.
Refrigerant Circuit
The Fluorocarbon charged in the refrigerant circuit is compressed by the compressor and cooled by the condenser to become liquid. Then, going through the capillary tube, it is decreased the pressure to reach a low temperature. Passing through the cooler part, it draws heat from compressed air and intensely boils. Finally it is inhaled into the compressor again. The capacity control valve opens to prevent dew drops from freezing when compressed air is cooled enough.
