TROUBLE SHOOTING
This section is intended to serve as a general guide for identifying the potential functional problems
which occur in operation of Amico manifolds.
When an asterisk (*) appears beside the CORRECTIVE ACTION, the recommended procedure is
to replace the whole unit in question, with a substitute unit, until repairs are completed on the original
equipment.
Components removed for maintenance, must be serviced, repaired and tested, only by personnel
qualified to work on equipment used in medical service. Only original manufacturer’s parts, as
supplied by Amico, may be used in the maintenance of Amico manifolds.
