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. 

 

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. 

 

 

 

 

 

 

 

 

We recommend the bypass piping sets that 

 we are selling separately as accessories.

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.

Wiring 

 

Warning 

No one but qualified person should do the wiring work. 

 

Before wiring, you must cut the power off for safety. Do not work under any 
energized conditions. 

 

Supply power from a stable place, which is free from the effect of surge.             
Ensure that an Ground Fault Circuit Interrupter(GFCI) with appropriate capacity for 
earth leakage and load is used in the power supply of the product to prevent 
electrical shock and burnout of the compressor motor. See “6-1 List of 
specifications” for details. 

 

Supply power for the product should meet the specifications. 

 

The product should be grounded for safety. 

 

Do not connect the earth to a water pipe, a gas pipe, or a lightening. 

 

Do not plug too many leads into a single socket. That causes exothenmic heat or fire.

 

Do not convert the wiring to use. 

 

In European countries, a circuit breaker that meets the IEC standard should  

 

be used for the supply power. 

 
How to connect wiring 

Take off the front panel in front of the product and connect the power supply (AC200V) to the  

terminal base.  

Install an Ground Fault Circuit Interrupter(GFCI) to the power supply

 (Prepare by yourself)
