2. Transportation and Installation
2 - 4
2.2.3 Air piping
•
Connection to the inlet and outlet of compressed air should be made removable by using union and so on.
•
Hold the hexagonal fitting with spanner and so on, and connect the air piping fittings to the unit.
•
Prevent the weight of the piping or unreasonable pressure that is caused in the process of piping from loading
on the product.
•
Be careful not to let the vibration of the air compressor transmit.
•
If the temperature of compressed air at the inlet side is higher than 50
o
C, place an after-cooler after the air
compressor outlet line.
•
Use a material with low moisture absorption and dust generation, stainless steel, copper, Teflon® etc. for piping
of the compressed air inlet and outlet. Be sure to insulate to the outlet the piping. If piping is not insulated the
controlled outlet air may affected by piping outside temperature.
•
If the air supplied to the dryer contains a lot of oil or foreign matter, this can cause deterioration in performance.
Please install a main line filter or mist separator in the compressed air supply line to this dryer.
•
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.
*Be sure to install Valve 1 and Valve 2 as shown in “3.2 Operation”. We recommend installing a
silencer for the discharge of valve 1.
2.2.3 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 unit,
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.
