I created the waterbox using the following tutorial:

http://www.ks.uiuc.edu/Training/Tutorials/namd/namd-tutorial-unix-html/node7.html

In t-leap, first i generate a new pdb because i need to rename the
number of residues because i have the different monomers, so in this
way, i obtain one.
After, i load this pdb and follow the next steps:

        Welcome to LEaP!
        Sourcing leaprc: /opt/amber10//dat/leap/cmd/leaprc
        Log file: ./leap.log
        Loading parameters: /opt/amber10//dat/leap/parm/parm94.dat
        Loading library: /opt/amber10//dat/leap/lib/all_nucleic94.lib
        Loading library: /opt/amber10//dat/leap/lib/all_amino94.lib
        Loading library: /opt/amber10//dat/leap/lib/all_aminoct94.lib
        Loading library: /opt/amber10//dat/leap/lib/all_aminont94.lib
        Loading library: /opt/amber10//dat/leap/lib/ions94.lib
        Loading library: /opt/amber10//dat/leap/lib/water.lib


        loadAmberParams parm99.dat

        loadpdb xxxx.pdb (this is the pdb with the new atom numeration)

the result i obtain is :

        .......
        (Residue 9990: WAT, Terminal/last, was not found in name map.)
        (Residue 9991: WAT, Terminal/last, was not found in name map.)
        (Residue 9992: WAT, Terminal/last, was not found in name map.)
        (Residue 9993: WAT, Terminal/last, was not found in name map.)
        (Residue 9994: WAT, Terminal/last, was not found in name map.)
        (Residue 9995: WAT, Terminal/last, was not found in name map.)
        (Residue 9996: WAT, Terminal/last, was not found in name map.)
        (Residue 9997: WAT, Terminal/last, was not found in name map.)
        (Residue 9998: WAT, Terminal/last, was not found in name map.)
        (Residue 9999: , Terminal/last, was not found in name map.)
        Unknown residue: number: 9999 type: Terminal/last
        ..relaxing end constraints to try for a dbase match
          -no luck
        Joining NGLU - ALA
        Joining ALA - SER
        Joining SER - SER
        Joining SER - ALA
        Joining ALA - PHE
        Joining PHE - ILE
        Joining ILE - VAL
        Joining VAL - VAL
        .....
        Creating new UNIT for residue: sequence: 10000
        Created a new atom named: within residue: .R< 10000>
          total atoms in file: 191739
          The file contained 1 atoms not in residue templates
