Mounting The Noise Elimination Frame - Fuji Electric FSJ Instruction Manual

5.4. Mounting the noise elimination frame

Remove the noise elimination frame screws, and apply acoustic coupler uniformly to the entire surface of the inside of the
noise elimination frame.
Check that the noise elimination heat-resisting rubber is not damaged and the double-sided tape is not peeled off.
Mount three noise elimination frames to which acoustic coupler has been applied to the pipe.
Install each noise elimination frame so that there is an interval of 50 mm between them as shown in the following diagram.
After securing the noise elimination frame screws with an Allen wrench, tighten them fully with torque of 1.4 Nꞏm using a
torque driver or torque wrench (M5, width across flat of 4 mm).
Note) When it is difficult to tighten the screw, unscrew it and check that it has no foreign substances on and the
engagement has no problem. Apply lubricating oil to the screw, and slowly tighten it to prevent it from being jammed.
Note) When using high-temperature grease (long-term type), pay attention to the following:
・Use the gloves attached to the product to apply the grease. If the grease gets on your skin, wash it off with plenty
of soap and water.
・Before using the product, refer to the grease precautions and safety data sheet attached to the product.
・Reapply the grease if the pipe temperature drops below -15°C when the equipment is shut off for a long time.
Note) Perform the work while making sure that water does not splash on the acoustic coupler.
Note) Store the acoustic coupler indoors in a cool and dark place. Since ultraviolet rays and foreign object contamination
may cause deterioration, store it after securely closing the lid.
Note) Tighten all screws uniformly. If screws are overtightened at one particular location only, the noise elimination frame
may become deformed, it may not be possible to obtain sufficient noise elimination benefit, and a measurement error
may occur.
Note) Wipe any protruding acoustic coupler with a cleaning cloth, etc.
