Before installation and or servicing electricity to the VFD, refer to the VFD
manufacturers’ user manual supplied with the Pressurizer-VS for all safety
warnings and cautions.
Do not connect and or operate the Pressurizer-VS with volts, hertz, or phase other
than that specified on the VFD. This may cause damage to the VFD and will VOID
the product warranty.
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.
