PRESSURE ADJUSTING 

1 

 

 

 

[Figure1]

 [Figure1] Open the cap of pressure range adjusting screw 

and the differential pressure adjusting screw.

 


 

If any flammable materials are around, never open.

Make sure that the power is completely shut off.


  

[Figure 2] 

 [Figure 2] Loosen the lock as a hexagon wrench and turn the open.


  


         [Figure 3]                [Figure 4] 

 


 

[Figure 4]. Insert a screwdriver into the screw hole of the open differential pressure regulation 

and pressure ranges, such as turning the screw to adjust the pressure.

 

     - After pressure adjustment,

       be sure to close the lid of the compartment and tighten the cap of screw for the explosion-proof features.

 

 

  

                           

1. Turn the pressure range adjusting screw to suit the 

   maximum pressure required.

 

2. Turn the differential pressure adjusting screw to suit 

   the needs of differential pressure 


3. While operating within a set pressure range, it will be 

  ON state  if it reaches the set differential pressure.

 

 

■ ATTENTION

All installation/maintenance work must be carried out by skilled staff. Always check that the system is gas-tight after installation. 

Failure to follow this manual can result in dangerous situations or damage to the product.

 

 

■ INSTALLATION

1. Warning

  - Select a product based on the operating pressure,depending on the model specifications table in

     this manual before installation.

  - All the gas supply must be shut off before installation.

  - Make sure that the pipeline is free from impurities and vibration-free before installation.

  - Only the "Pressure adjusting screw" and "Differential pressure adjusting screw" can be adjusted.

  - Do not bend sharply when pipe connections occur.

  - Keep the line length slightly longer to prevent vibration.

  - Before opening be aware of risks of dangerous ignition. 

  - Close the cover tightly before operating.

  - Function and holding tests must be carried out after installation.

  - When installing to ammonia system, please contact us.

 

 

2. Installation Location

  - This product can be installed in any position.

 

 

■ ADJUSTMENT

Before connecting the pipe, adjust setting value first. 

 

 

■ Standards and specifications of this product are subject to change without prior notice for improved performance.
