Press the “Booster Pump” switch, then the
“Start” switch, and finally the “Stop” switch.
Ensure that the High Pressure Pump Electric
Motor and the Booster Pump Electric Motor
turned in the proper rotation. If either or both
motors turned in the wrong direction refer to
the wiring diagrams in Section 11 to correct.
18. Multi Media Filter Preparation
The Multi Media Filter should be loaded
with gravel and #20 silica sand. When new,
the media must be back washed then rinsed
prior to use. These procedures fluff and clean
the silica sand base. During back washing the
suspended solids are discharged. Follow the
Backwashing Instructions on Page 9 – 5.
When Backwashing is complete, make sure
to position the Multi Media Filter Valves for
Normal Operation.
19. To start the system press the “Start” Switch, or
press the “Booster Pump” Switch and then the
“Start” switch.
If the system automatically shuts off after
several seconds of operation this may be due
to a system fault. Look at the Touch Pad to
confirm whether a fault has occurred.
20. Bleed all air from the Commercial Pre-filter
[14] and Oil/Water Separator [17] by opening
the air bleed valve located at the top of the
each housing [16 & 18] and close when water
displaces all of the air.

21. Slowly adjust the Back Pressure Regulator
Valve [33] by turning clockwise to increase
the pressure to the proper setting (850 psi for
35,000 ppm seawater).
For BRACKISH WATER operation, adjust
the pressure from 100 to 850 psi so the
product water output, is within the system
specifications.

CAUTION
: Do not exceed product water
flow specifications.
22. If any abnormality develops, stop the System
and correct the problem.
23. Use the Product Water Flow Meter [42] to
measure the product flow. The system may
not produce “potable” water for up to 30
minutes. The salinity of the Product Water
diminishes gradually, until it reaches the
factory setting at which time it is directed
to the “potable” (good water) position. This
allows product water to pass into the Post
Filtration components, and onto the Ship’s
Storage Tank [46].
16. Check for:
a. A constant feed water flow.
b. A consistent system pressure.
c. Leaks in the system.
d. Unusual noises or other occurrences.
