c. Check the size of the intake piping is still suitable at the new equivalent length. Should there be
any discrepancies, re-estimate the next larger size and replicate the steps above. The line
may also be sized more precisely by conducting an actual calculation. Intake piping must be
sized to induce no more than 4inches water column vacuum at the compressor when all
compressors are operating. (Use total capacity for this calculation with all compressors running).
For unusual lengths or other circumstances, please contact your Local Amico Source representative for
assistance.
5. Finalize the connection to the distribution piping and size the system piping.
