This manual is intended for use with ANSU WOM-3 and WOM-4
Water Oscillating Monitors.
Those who install, operate, maintain, or service these monitors
should read this entire manual. Specific sections will be of particular
interest, depending upon one’s responsibilities.
Water oscillating monitors are mechanical devices. They need peri-
odic care. Maintenance, to provide maximum assurance that the
monitor will operate effectively, should be performed every six
months or more frequently if desired.
Discharge testing should be conducted at intervals in accordance
with end-user policies or with the authority having jurisdiction,
whichever is more strict.
