• Refer to “Chapter6 6-3 Dimensions” for the dimensions.
• The air dryer should be bolted by anchor bolts to prevent falling. We recommend the anchor bolt sets
that
2-2-3 Air piping
•Connection to the inlet and outlet of compressed air should be made removable by using union and so on.
•Pressing the hexagonal fitting with screw wrench and so on, connect the air piping fittings to the body.
•When mounting any part such as an air filter on the fitting at the compressed air inlet or outlet port, support the
part to prevent excessive force from being applied to the product.
•Be careful not to let the vibration of the air compressor transmit.
•If the temperature of compressed air on the inlet side is higher than 50
o
C, place an aftercooler after the air
co0mpressor. Or, make the temperature of the place where the air compressor is installed lower than 50
o
C.
•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.
If a metallic flexible tubing is used for the air gateway piping, the allophone might be generated in piping. In that
case, please change to the piping of the steel pipe.
•Please set up the filter in the drier secondary for the drain dispersion prevention when a rapid pressure
fluctuation and the fluid velocity variation happen.
2-2-4 Drain Tube
•A polyurethane tube of 10mm external diameter is attached to the drain tube. The outlet end of the tube is
released to atmosphere. And let drain flow through the tube into a scupper and so on.
•Using the pressure of the compressed air, drain will be discharged periodically. Fix the outlet end of the tube so
as not to swing during discharge.
•Prevent the drain tube from riser piping.
•Prevent the drain tube from being folded or flatted. Since the drain tube is coming from the bottom of the body,
be careful to avoid the body from stomping over the tube during installation.
Warning
During drain work, follow the procedure that you define to keep the safety of worker (ex. Put on
protective glass, apron, and gloves).
In case that oil gets mixed in the wasted water that is discharged from the auto drain, the waste liquid treatment
is necessary. Handle it following the bylaw or regulation of local government.
We recommend the bypass piping sets that
we are selling separately as accessories.

•Even while the dryer is removed, only when compressed air is needed,
open the bypass piping valve.
•Close the compressed air inlet and outlet valve.
•Unscrew the front panel fixing screw (in 2 points) and remove the
front panel with upholding it a little.
•Open the residual pressure release cock of auto drain tube, and
release compressed air pressure left inside of the product.
Refer to the figure at right .
Warning
No one but qualified personnel should do the electric wiring.
Cut off the power supply for safety before the wiring. Do not work under energized
condition.
Warning
No one but qualified personnel should do the air piping.
Separate the compressor from the product for safety before removing the piping.
Do not remove any piping when there is remaining compressed air pressure inside
of it.

3 Operation/Shutdown
Caution
No one but someone who has enough knowledge and experience about the product and
incidental devices should operate or shut down the product.
3-1 Check points before operation
Before trial run, check the following points:
• Installed Conditions:
By visual inspection , check that the product is level.
make sure the product is tied down with anchor bolts.
Do not place heavy objects on the top of the product.
Ensure the piping does not apply load to the unit.
• Power cord, and the ground should be connected firmly.
• Drain tube should be connected correctly.
• Make sure the piping for compressed air is connected correctly.
3-2 Operation
Start operation according to the procedure below.
•Turn on the breaker of the main power supply. Then, turn on the illuminated switch.
•The lamp will light up. Few minutes later, the cooling fan will rotate and hot air will be exhausted from the
ventilation grille.
Place of the ventilation grille: Right Side Ventilation Grille
•Open the IN / Out side valve slowly. Make sure the bypass valve is completely closed. Confirm there is no air
leakage.
•Depending on the condition of compressed air or ambient temperature, the cooling fan sometimes alternates
between rotation and stop at the beginning. Then, the refrigerator will go into continuous run and the pointer of
the evaporation thermometer will indicate in the green zone. If the pointer of the evaporation thermometer
indicates higher than the green zone, refer to “Chapter5 Troubleshooting.”
•After a while from the start of flowing the compressed air, drain will be discharged from the drain tube
automatically.
•Keep the condition of continuous run to use.
Caution
Avoid frequent On/Off operation, which may cause problems.
The auto drain used for the product has a structure that closes the valve with air pressure
higher than 0.15MPa. Therefore, until the pressure increase, air will be emitting from the
drain outlet at the start of opening the “IN” valve. Keep in mind that sometimes the
pressure cannot increase due to under-sized air compressor.
