Section 4
Installation, Initial Start-Up and Operation
4.1 Piping Installation
The following procedures are to aid the operator in installing, operating and maintaining
the Thrush Pressurizer-VS. All procedures are to be performed by experienced, trained,
and certified personnel only.
Before the unit is installed, the unit should be visually inspected for any irregularities that
may have occurred during shipping. If any parts are missing or damaged, contact your
representative. If no issues are detected, continue with installation.
Before making any piping connections, assure that all piping is clean and free of
any foreign materials such as debris or scale. Foreign material in the piping can
cause damage to the unit and or affect the performance and operation. Manual
shutoff valves should be installed upstream and downstream of the system to act
as an isolation device. These valves should be in the closed position and remain
so until the installation is complete.
