GENERAL
This work package contains information and instructions for removal and installation of the 0.75-inch (19.05-mm)
pilot-operated solenoid valves on the Ultrafiltration (UF) module used in the Lightweight Water Purifier (LWP).
There are seven valves in the UF module; three valves with a 0.052-inch hole drilled inside the housing are at the
top in the UF reject piping, one valve in the middle in the tank inlet piping, and three valves at the bottom in the
fast flush piping.
REMOVAL
1. Determine solenoid valve to be replaced. See WP 0054 00 through WP 0060 00. See Figure 1.
