2 Transportation / Installation

 

 

 

 

Circumstances where too much force 

and weight are put on the body of the 

equipment that causes it to deform. 

 

Circumstances where enough spaces 

cannot be taken to do maintenance (in 

the plant where the equipment is 

operated). 

Spaces needed for maintenance 

Front 

: 600 mm 

Rear 

: 600 mm 

Top 

: 600 mm 

Right 

: 600 mm 

Left 

: 600 mm 

 

Locations the ventilation grille of the 

equipment can be blocked. 

 

Place where rejection style air of air 

compressor or other driers (hot wind) is 

inhaled.

Warning 

Do not use and store in environment having compressed air or ambinet atmosphere which 

includes the following substances. It could result in failure of the product and damage of 

components, which leads to injury.  

- Corrosive gas, Organic solvent, Chemicals

 

2 - 2 - 2  Anchorage 

 

The air dryer should be installed on a vibration-free, stable, horizontal flat surface.

 

 

Refer to “Chapter6 6-2 Dimensions” for the dimensions.

 

 

Fix by bolts to prevent falling down. The bolts can be prepared separately as an accessory.

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. 

 

Prevent the weight of the piping or unreasonable pressure that is caused in the process of piping from 

loading on the equipment. 

 

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 80

o

C, place an aftercooler after the 

air compressor. Or, make the temperature of the place where the air compressor is installed lower than 

80

o

C. 

 

Flush pipes and fittings before connection to prevent dust or chips from entering the air dryer. Those 

dusts or oil entered in the piping cause incomplete refrigeration and failures of the equipment. 

 

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. 

 

 

 

 

 

 

 

 

 

We recommend the bypass piping sets that 

 we are selling separately as accessories.
