• Make sure that the PN indicated on the body valve (PN16) complies with the operating condition of the plant;<br />
• Make sure that the body and sreen materials comply with the operating conditions of the plant (type of fluid);<br />
• Before installation clean the strainer inside to remove any foregn matter;<br />
• Install strainer according to the flow arrow casted on the body;<br />
• Install strainer avoiding strenghts and stresses which could cause breakage.<br />
USE R<strong>EC</strong>OMMENDATIONS<br />
• Avoid water hammering and sharp temperature and pressure changes;<br />
• Use suitable protections in presence of explosive, inflammable, toxic or corrosive fluids or if high or low operating<br />
temperature are present.<br />
OPERATING INSTRUCTIONS<br />
Following to the direction of the flow indicated on the body with the flow arrow, this strainer acts automatically the function to<br />
filter the fluid. No manual action is required.<br />
WARNINGS<br />
The pressure <strong>equipment</strong>s, due to their characteristics and to the fluids which they are in contact with, may represent<br />
an hazard to people and environment. To prevent and limit the risks deriving from the pressure <strong>equipment</strong> operation and to<br />
avoid personal injuries, the final user/maintenance technician must be sufficiently trained and expert.<br />
This operating and maintenance instructions are useful but not sufficient to prevent the risks deriving from the non correct use<br />
of pressure <strong>equipment</strong>s; the installer will find indications to minimize the effects deriving from intrinsic risks which cannot be<br />
eliminated.<br />
