Introduction
This manual provides the information needed for the shop mechanic to determine the condition of the Micropump
Model 668-400-2 Pressurematic Water System and enable him/her to restore it to serviceable status if necessary.
The manual first describes the Pressurematic Waster System. It then presents detailed procedures in a logical
sequence, detailing how to assess serviceability, disassemble and clean, check, repair, assemble, and store. An
Illustrated Parts List concludes the manual.
All procedures are shop verified; that is, the manufacturer has used the procedures presented herein.
The way to use the manual depends mainly on the immediate objective. For example, to reach a go-no go decision
on a Pressurematic Water System, one need only refer to Testing and Troubleshooting... to make a repair, refer to
Repair... and so on. If the objective is a complete overhaul, however, one must make use of the whole manual.
Note: The manual covers the overhaul and maintenance of the Model 668-400-2 Pressurematic Water System with
the P/N 9978-Motor and Switch Assembly.
