The no marketing proviso for seriously underfilled units forces the filler to either systematically overfill as foreseen in the regulations or to install check-balances or other devices to actively control a high percentage (ideally 100%) of the containers and either discard or recycle under-filled ones. 

The level of site acceptance testing should be such as to demonstrate satisfactory operation of the system functions in conjunction with the manufacturing process equipment and may involve control loop tuning. Site acceptance testing in its basic form should include installation checks, power-up, diagnostic checks, and commissioning of process and safety-related operational I/O, controls, sequencing, interlocks, alarms, and reports. 

Evaluate the pump chosen for the installation. Check the specific speed of a centrifugal pump using the method given in Example 6.20. Once the specific speed is known, the impeller type and approximate operating efficiency can be found from Fig. 6.12.

A disadvantage of pulsed columns is the need for a pulsing pump. However, similar pumps are needed in any case for transfer of liquids. In fact, the pulsing can also be used for transfer by installing check valves in the piping between the columns, although with some sacrifice in operating flexibility. 

When you replace a belt, always check the tension immediately after Installation. Check it again after 24 hours of operation.
