Accessories
• The threaded barbed adapter may be cleaned by washing them with a
65% alcohol/water solution (per manufacturer’s instructions). The parts
must be thoroughly dry before they are used.
Because of the variability of the cleaning processes, Maxtec cannot provide
specific instructions. Therefore, we highly recommend referring to the manu-
facturer’s instructions on the details of method.
