Cautions about Reinstallation 

 

Caution 

No one but someone who has enough knowledge about the product and incidental 
devices should reinstall in another place. And following instructions must be executed. 

If you move the product and reinstall it into another place after some operations (including trial running), 
instructions that are not only following ones but also all of those in the chapter 2 should be followed. 

 
Disassembly of the power cable 

Cut off the power source when you disassemble the power cable. 

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. 

Disassembly of the air piping 

Warning 

No one but qualified personnel should do the air piping. 

Separate the compressor from the product for safety before removing the iping. Do not 

remove any piping when there is remaining compressed air pressure inside of it.

 

Remove the s

eal tape completely after detaching the piping. Remained tape will cau

se imperfect 

cooling and failure by entering into the body of the product.  

 

Residual compressed air pressure release procedure 

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. 

Make sure the ball valve located next to the auto drain opened. 

Case Assembly

The ramainder depressure cock.

It opens when turning in the

    drection og the arrow of figure.

Open the auto drain residual pressure release valve
