Every instrument, control panel, field device, and control valve should be inspected by site inspectors to ensure that they have been installed correctly in accordance with approved installation details. In addition, instrument and other manufacturers should be on-site to certify that their equipment has been installed correctly. Manufacturer-authorized representatives should then certify installation in writing by providing an installation certificate. This will ensure that equipment or device malfunctions discovered during testing are not caused by improper installation. It is also a good idea to involve the owner or facility personnel at this stage so that they can identify any concerns they have with installation.
