NOTE: Do not run the system dry for any length of time as this will cause excessive wear of the
polymer feed pump components and the Mixing chamber motor shaft seal. Momentary operation
to verify power and shaft rotation is acceptable.
CAUTION! The Mixing chamber is rated for 150 PSI. Do not exceed this pressure – operation of
the unit at pressures greater than 150 psi can cause injury or equipment damage.
