5. Maintenance

5.1 Precaution for installation

Caution

1. When installing, check the direction of the product so that the fluid flowing and the arrow marked on

the product are in the same direction.

* Setting the product in wrong directions prevents the product from performing as intended.

2. When installing, secure the space to remove the screen.

* Failure to follow this notice hampers cleaning of the screen.

3. Do not apply excessive load, torque or vibration to the product.

* Failure to follow this notice may result in fluid leakage.

4. Do not apply excessive load, torque or vibration to the product.

* The foreign matter corresponding to the specified mesh size may not be completely caught

constitutionally.

1. Clogging inside the product can be known from the differential pressure measured, when pressure

gauges are installed in upstream and downstream of the product. [See Fig. 1 in “7. Piping
Example.”]

2. The product shall be installed with its cap or cover faced downward.

* If drainage or similar problem occurs in a steam line, incline the product to the position at which

the cap or cover is kept horizontally.

3. If the product can only be installed to run the fluid from the bottom to the top, make sure to install a

blow valve in order to remove the scale accumulated at the bottom of the riser pipe. [See Fig. 2 in
“7. Piping Example.”]

4.When the fluid is steam, connect piping so that the cap or cover faces sideways in order to minimize

the pooling of drain. [See Fig. 3 in “7. Piping Example.”]

5.2 Precaution for operation

Warning

1. When the product is used for hot fluid, do not touch the product with bare hands.

* Failure to follow this notice may result in scalds or injury.

2. Do not retighten the cap or cover after leading fluid into the product.

* Failure to follow this notice may damage the gasket and cause outside leakage.
* Failure to follow this notice may result in scalds or injury.

Caution

1. Use the product under a maximum pressure loss below 0.1 MPa. Periodically clean the screen.

* Failure to follow this notice may damage the screen.
