1.4 Filter System Assembly
Placing, Arranging, and Leveling Vessel(s)
Skid mounted systems:
a) Place system skid in desired location and level skid.
NOTE: If system was shipped assembled, the pipe assembly may be loose at flanges to
avoid flex damage. Some systems will be shipped broken down to avoid damage from flexing.
b) Arrange vessels with valves front.
c) Multi vessel systems are labeled and should be arranged in order from left to
right. (Use lower pipe manifold as guide for spacing and leveling vessels.)
CAUTION! WARNING! CAUTION!
PERSONAL INJURY MAY RESULT!
READ FOLLOWING CAREFULLY BEFORE PROCEEDING!
TIPPING HAZARD may exist on empty, freestanding, multi-vessel systems with upper
manifold attached.
READ THE FOLLOWING PARAGRAPH BEFORE PROCEEDING!
With vessels properly aligned and leveled and with lower manifold and pipe stands
attached, add base (stone) media. (See media addition sec 6 in this manual).
This will counter balance the system and reduce tipping hazard.
NOTE: Be sure that vessels are properly placed and aligned before adding base
media. Vessels will be difficult to move with media added.

46/07
Assembling Manifolds
NOTE: Flange bolts, and gaskets are packed in separate cardboard box contained in
filter shipping crate.
a) Align upper and lower manifolds with vessels. Install flange gaskets and bolt
manifold flanges to vessel(s). Do not tighten flange bolts at this time. Minor
adjustments in vessel alignment may be necessary at this time.
b) Assemble all interconnecting manifold flanges and secure unions. Tighten all
connecting bolts at this time.
WARNING:
DAMAGE TO MANIFOLD MAY RESULT IF THE MANIFOLD IS PLACED UNDER STRESS OR IF
FLANGE BOLTS ARE OVER TIGHTENED!
Valve Control Wiring
For single vessel systems: valve wiring is pre-wired at factory.
For multi-vessel systems: valve wiring for vessel A is pre-wired at factory. Wiring for
remaining vessels is coiled at each vessel. Wires are tagged with number
corresponding to the output number on the PLC. (Ref: drawing TBIO)
1.5 Electrical
General:
NOTE: Filter control panel and all pumps must have a solid earth ground. Conduit and water
pipe are NOT acceptable ground.
a) All wiring must be properly sized, rated, and connected in accordance with local,
state, and national electrical codes.
b) Filter system should be on a dedicated circuit originating at a service disconnect
panel.
NOTE: If filter pump motor starter is not factory supplied it must be wired with a
dedicated disconnect.
c) Penetrations to filter control panel should be made with watertight connectors to
preserve panel NEMA 4X rating.

56/07
Control / Motor Starter Package (Ref: Drawing CPMS)
a) Factory installed motor starter package includes a service disconnect, motor starter,
and transformers pre-wired to the PLC. These systems require a single point
electrical connection to the service disconnect. Line service must be rated to pump
motor requirements.
Standard systems are factory set for 460V, 3ph service. Optional power supply
factory wired as ordered.
b) Wire the pump motor from the motor starter with seal tight (provided).
NOTE: If optional backwash booster pump is used and a second motor starter is
factory supplied, refer (drawing CPMS) for proper connection points.
NOTE: Do not operate pump(s) dry. Damage to pump seal and shaft may occur.
Control Package (Ref: Drawing CPIO)
a) The control package is pre-wired at factory
b) Two sets of terminals, located in the control panel, are provided for pump control.
Reference drawing CPMS for terminals.
c) Power for motorized valves is supplied from control panel terminal strip.
(See Section 1.4 for instructions).
d) Fuse holders connected to output terminals 9 & 11 are intentionally left with no
fuses. Fuses should not be installed or removed unless specific instructions are
received from AmeriWater 800.535.5585.
Output #9 will be fused, (if applicable), at start up to convert from city water to
system water backwash.
e) Output #11 will be fused, (if applicable) to change timed backwash from 24 hours to
7 days. Timed backwash should be changed only for systems operating on a
closed loop and only after consultation with AmeriWater.
NOTE: Changes to these options without instructions from AmeriWater may void
the filter warranty.

66/07
1.6 Pipe Connections
Recommended pipe size for all pipe connections are noted in schedule.
(Ref: Drawing CW)
Connecting pipe should be of materials compatible in construction to filter manifold.
Dielectric fittings are highly recommended if dissimilar metals are used.
For pipe runs exceeding 20 feet from filter system consult AmeriWater for pipe size
recommendations.
The companion full-face flange to the suction side of the filter pump is to be provided by end-
user or contractor.
Basket or Y strainer (with gauges before and after strainer) is recommended ahead of filter
pump.
Ref: Drawing CWT for typical installation.
Properly secure all pipe runs with M & F clamps (or similar). Pipe movement may cause filter
and / or pipe damage.
Supply and Return Lines
NOTE: Isolation valves are recommended convenient to filter.
a.Connect influent (supply) line from pre-selected point in cooling system to
suction side of filter pump.
NOTE: A foot valve / check valve should be installed on suction side of self-priming
pump to prevent loss of pump prime.
b. Connect effluent (return) line from the outlet connection to the pre-selected point in the cooling
system (downstream of inlet connection).
NOTE: Filter return must be connected to a point in the cooling system where cooling system
pressure is equal to or less than pressure to filter pump suction.
NOTE: Filter supply and return lines should be connected to the cooling system where they
are in an area of 'common' flow.

76/07
Backwash Supply
NOTE: If filter is designed to use cooling system water for backwash, no backwash supply pipe
is required in this section. (Skip to waste line section)
NOTE: Clean water supply is always recommended for closed loop filters.
Backwash supply requires min / max 30/70 psig. An isolation valve is
recommended, convenient tofilter. Backflow preventer is recommended and
commonly required bylocal codes when potable water is used for backwash. A
pressure gauge is recommended atthe discharge of the backflow preventer.
NOTE: An efficient backflow preventer will create approximately 12 psig loss in line
pressure. A minimum of 30 psig must be available at outlet side of backflow
preventer. If backwash and cooling tower make up are connected to the same
supply, be sure 30 psig is available when tower is calling for water.
Connect properly sized backwash supply line to inlet side of backwash flow control device.
Waste Line
NOTE: Ensure drain is adequately sized and free flowing to handle backwash flow.
A swing check valve is recommended for waste lines with a vertical lift. Check valve should be
installed immediately after the filter waste line connection.
Ball Type or Spring Type Checks Are Not Acceptable.
For drainpipe runs exceeding 20 feet or an 8-foot lift from filter system, consult AmeriWater for pipe
size recommendations.
Connect properly sized drain line to filter backwash drain.
