9) PLANKTON FILTER
This optional filter assembly contains a cleanable
ultra fine monel mesh screen. The mesh screen traps
suspended solids or biological growth such as plankton.
It also provides longer life to the Pre-filter Elements and
in turn provides lower system maintenance costs. As
with all prefiltration components the Plankton Filter mesh
screen must be free of debris in order for the Feed Water
to flow through it.
Problems and Symptoms appearing and caused by the
Plankton Filter:
a)
The Feed Water Pressure into the Plankton Filter is
higher than normal, and the Feed Water Pressure
into the High Pressure Pump is lower than normal.
The pressure differential readings across the
Plankton Filter indicate that the element is filled
with debris blocking the feed water.
Solution : Clean the Plankton Filter Element.
10) MULTI MEDIA FILTER
This optional filter assembly contains a back-washable
bed of sand and gravel. The sand traps suspended
solids larger than 30 microns which provides longer life
to the pleated cartridge prefilter elements minimizing
maintenance intervals, maintenance labor, and filter
element cost. Pressure and flow will be restricted
as the sand bed becomes clogged with debris and
marine growth. The sand bed is washable by reversing
the feed water flow across it. This process is referred
to as Back Washing.
Problems and Symptoms appearing and caused by the
Plankton Filter:
a)
The Feed Water Pressure into the Multi Media
Filter is higher than normal, and the Feed Water
Pressure into the High Pressure Pump is lower
than normal.
The pressure differential readings across the
Multi Media Filter indicate that the Multi Media
Filter requires back washing.
Solution : Back wash the Multi Media Filter.
11) DUAL PRE-FILTER
This two stage filter removes suspended solids first
through a 20 micron cartridge filter element then through
a 5 micron cartridge filter element. By stepping the
filtration both prefilter elements gain longer life and
require less maintenance labor and prefilter element
7) T-CONNECTOR PRESSURE PICK-UP
Booster Pump Outlet/Prefilter Inlet for line pressure
pick up to Low Pressure Transducer #1 between the
outlet of the Booster Pump and the inlet of the first
prefiltration component.
Problems and Symptoms appearing and caused by the
T-Connector Pressure Pick-Up:
a)
The Low Pressure Transducer #1 does not
register pressure.
The 1/4 in. (5 mm) O.D. tube connecting the
T-Connector to the Low Pressure Transducer
Manifold may become kinked or debris may
block the tube.
Solution : Replace any hose or tube that is kinked.
Disconnect each end of the tube and blow air
through the tube to ensure that it is not blocked.
8) LOW PRESSURE TRANSDUCER #1
Booster Pump Outlet or 1st Prefilter Inlet for line pressure
pick up from the Outlet of the Booster Pump to the Inlet
of the 1st Prefiltration component.
The Low Pressure Transducer sends a DC voltage
signal to the System Control Logic. The minimum value
is .5 VDC when no pressure is applied to it, and the
maximum value that the System will accept is 4.5 VDC.
The variation of voltage output from the Transducer is
converted to pressure value by the System Control Logic.
Problems and Symptoms appearing and caused by the
Low Pressure Transducer #1:
a)
The Low Pressure Transducer #1 does not register
pressure or the pressure displayed is inaccurate.
The 1/4 in. (5 mm) O.D. tube connecting the
T-Connector to the Low Pressure Transducer
Manifold may become kinked or debris may
block the tube.
Solution : Replace any hose or tube that is kinked.
Disconnect each end of the tube and blow air
through the tube to ensure that it is not blocked.
The pressure readings at the Touch Pad are
inaccurate. The minimum voltage output is below
.5VDC and or the maximum voltage output is
above 5 VDC.
Solution : Check wiring and connections to and
from the Transducer. Replace the Transducer.
