6. Disassembly, Cleaning and Reassembly
Excessive amount of foreign substances inside the product reduces filtration area and
hampers fluid flow. If the product is kept for such condition, the screen is damaged and
results in adverse effect on the piping system due to excessive pressure difference.
6.1 Precaution for disassembly and inspection
Warning
1. Completely discharge the pressure inside of the product, piping and equipment prior to disassembly
and inspection. When fluid is hot, cool down the product.
* Failure to follow this notice may result in scalds or injury due to the residual pressure.
1. After checking the pressure gauge to make certain there is no pressure inside the body [1], remove
the cap or cover [2] and screen [3]. Clean up the screen [3] by compressed air or water.
6.2 Precaution for reassembly
Caution
1. Clean the gasket contact surfaces of both the body and the cap or cover.
* Improper cleaning may cause fluid leakage at the gasket resulting in scalds or injury.
2.
When installing caps and bolts, apply anti-galling agent to the threads.
* If you do not apply anti-galling agent, you may not be able to remove the cap and bolt.
1. After cleaning the gasket contact surfaces of both the body [1] and the cap or cover [2], attach a
new gasket [4] to the cap or cover [2], and then attach the cleaned screen [3] into the groove on the
cap or cover [2]. Install the assembly (cap or cover [2], gasket [4], and screen [3]) to the body [1].
