Note: Our technical personnel, who will visit when the ModuSat has been installed to
arrange for its final commissioning and calibration, do not perform the role of inspector
and/or approval officer for the system. Its compliance with standards and instructions
remains the exclusive responsibility of the installation company.
The ModuSat may have been transported and handled many times if you consider the on-
site storage, handling and installation, therefore it is vitally important that all unions and
connections are checked and tightened as required.
