XI. TOXICOLOGICAL INFORMATION

Silicosis: The major concern is silicosis, caused by inhalation and retention of respirable crystalline silica dust.
Silicosis can exist in several forms, chronic (or ordinary), accelerated, or acute.

Chronic or Ordinary Silicosis (often referred to as Simple Silicosis) is the most common form of
silicosis, and can occur after many years of exposure to relatively low levels of airborne respirable crystalline silica
dust. It is further defined as either simple or complicated silicosis. Lung lesions (shown as radiographic opacities)
less than 1 centimeter in diameter characterize simple silicosis, primarily in the upper lung zones. Often, simple
silicosis is not associated with symptoms, detectable changed in lung function or disability. Simple silicosis may be
progressive and may develop into complicated silicosis or progressive massive fibrosis (PMF). Complicated
silicosis or PMF is characterized by lung lesions (shown as radiographic opacities) greater than 1 centimeter in
diameter. Although there may be no symptoms associated with complicated silicosis or PMF, the symptoms, if
present, are shortness of breath, wheezing, cough and sputum production. Complicated silicosis or PMF may lead to
death. Advanced complicated silicosis or PMF can result in heart disease secondary to the lung disease (cor
pumonale).

Accelerated Silicosis can occur with exposure to high concentrations of respirable crystalline silica over a
relatively short period; the lung lesions can appear within five (5) years of the initial exposure. The progression can
be rapid. Accelerated silicosis is similar to chronic or ordinary silicosis, except that the lung lesions appear earlier
and the progression is more rapid.

Acute Silicosis can occur with exposures to very high concentrations of respirable crystalline silica over a
very short period of time, sometimes as short as a few months. The symptoms of acute silicosis include progressive
shortness of breath, fever, cough and weight loss. Acute silicosis can be fatal.

Cancer:

IARC: The International Agency of Research on Cancer (IARC) concluded that there was “sufficient

evidence in humans for the carcinogenicity of crystalline silica in the forms of quartz and cristobalite from
occupational sources”, and that there is “sufficient evidence in experimental animals for the carcinogenicity of quartz
and cristobalite.” The overall IARC evaluation was that “crystalline silica inhaled in the form of quartz or

Page 4 of 7

Prepared January, 2 2018

12

cristobalite from occupational sources is carcinogenic to humans (Group 1).” The IARC evaluation noted that
“carcinogenicity was not detected in all industrial circumstances studies. Carcinogenicity may be dependent on
inherent characteristics of the crystalline silica or on external factors affecting its biological activity or distribution
of it polymorphs.” For further information on the IARC evaluation, see IARC Monographs on the Evaluation of
Carcinogenic Risks to Humans, Volume 68, “Silica, Some Silicates…” (1997).

NTP: The National Toxicology Program, in its Ninth Annual Report on Carcinogens, classified “silica,
crystalline (respirable)” as a known human carcinogen.

OSHA: Crystalline silica (quartz) is not regulated by the US Occupational Safety and Health
Administration as a carcinogen.

There have been many articles published on the carcinogenicity of crystalline silica, which the reader should consult
for additional information. The following are examples of recently published articles:

SEQUENCE OF OPERATION
This section describes the operation of standard High Efficiency Filter Systems as they are
shipped from the factory. It is intended to be an aid to understanding the general operation
of the unit for the equipment operator and should not be considered a technical reference.

Modes of operation

There are two modes of operation for the CW Series.

Service mode – Incoming water is pumped into the top of the filter tank(s), through the filtering
media, out the bottom of the tank(s) and returned to the cooling system.

Backwash mode – This is the CW Series self-cleaning mode. Water is directed to enter the bottom of
the tank at a controlled flow rate. The media bed is lifted and separated loosening the trapped
particles. The water exits the top of the tank carrying away the previously filtered particulates to the
drain.

Start-up

When power is applied to the CW Series filter, the filter cycle valves will advance to the service mode.
In service mode, all service valves (1&2) will be open and all backwash valves (3&4) will close. The
filter pump will be disabled for a period of 60 seconds to allow the cycle valves to move into proper
position.

Applying power to the control box also starts a timing mechanism that initiates automatic
backwash cycles at predetermined intervals.

Initiating the backwash cycle

There are three ways to initiate the backwash cycle.

Automatic – The PLC has a built-in timer that is designed to initiate a backwash cycle every 24 hours.

On-demand – A differential pressure gauge monitors the input and output water pressures and
sends a signal to the PLC to start a backwash when the difference between inlet and outlet water
pressure reaches the preset threshold. This feature is also automatic.

Manual – The backwash cycle can be initiated manually at any time by pressing and holding the
“manual backwash” pushbutton on the front of the control box, for a period of 20 seconds. Once
initiated, the backwash cycle will commence without operator assistance.

23 6/07

Backwash sequence of operations

Once a backwash has been initiated by any of the above methods, the sequence of events that
follows will always be the same. The sequence is as follows:

1) If a filter is using city water for backwash, the pump goes off. If the filter uses system

water for backwash, the pump will be deactivated until the cycle valves turn , and the pump is
reactivated.

2) On single and multiple tank filters, all service valves (1&2) close at the same time. Event time is 60

seconds.

3) Tank #1 backwash indicator light is illuminated.

4) Tank #1 backwash valves (3&4) open. Backwash duration is 5 minutes.

5) When Tank #1 backwash is complete the indicator light is extinguished.

6) Backwash valves (3&4) close.

7) Steps 3 through 7 are repeated for each additional tank for multi-tank systems.

8) After all tanks have been backwashed, all service valves open. Event time is 60 seconds.

9) The pump returns to run mode and the CW Series Filter returns to service mode.

Aborting the backwash

In certain situations, it may be desirable to abort a backwash. A backwash in progress can be
aborted by pressing and holding the “manual backwash” pushbutton for a period of 10 seconds.

NOTE: If the backwash is being initiated by demand from the differential pressure switch, the
backwash will be delayed only briefly. Demand for a backwash will continue until the
differential pressure is brought below the preset threshold.

Automatic backwash timer

The backwash timer will automatically initiate a backwash at pre-determined intervals. The standard
interval is every 24 hours. This can be changed to a 7-day interval by installing a fuse in the fuse
holder labeled 7 for closed loop systems. Consult your AmeriWater representative for information.

Setting the automatic timer

The 24 hour or 7 day automatic backwash timer can be reset to zero by pressing and releasing the
“manual backwash” pushbutton on the control box 5 times within a 5 second interval. All backwash
indicator lights will flash twice to confirm the change. Thereafter, the CW Series will backwash 24
hours or 7 days from the time you reset the timer, unless a manual or on demand backwash is
initiated.

Note: In the event that electrical power is removed from the control box, the timer cannot continue
counting but will maintain the count it held when power was lost and continue counting when
power is restored. The backwash schedule will be delayed by the amount of time the power was off.
If the backwash time is important, the timer will need to be reset to bring it back on schedule. See
above paragraph for timer resetting instructions.

24 6/07

System Backwash Pump Enable

The CW Series is a pressurized filter system designed to operate at a specific water flow rate. To
achieve the specified flow rate, a pump is integrated into the CW Series . Normally, this pump runs
continuously whenever the system is in service mode and is turned off during backwash. Optionally,
the controls can be set up to operate the pump during backwash, as described in the backwash
sequence of operations (Step 1). This is accomplished by installing a fuse at the appropriate location
in the control box labeled P. Consult your AmeriWater representative for information. To disable
(turn off) the pump for maintenance, etc., rotate the pump selector switch on the control box to the
“off” position. This will disable the pump in all modes of operation.

External interface options

Inputs

performance will be lowered.

1.4. Always use horsepower-rated switches, contactor and

starters.

1.5. Motor Protection

1.5.1. Single-phase: Thermal protection for single-

phase units is sometimes built in (check name­plate). If no built-in protection is provided,
use a contactor with a proper overload. Fusing
is permissible.

1.5.2. Three-phase: Provide three-leg protection with

properly sized magnetic starter and
thermal overloads.

1.6. Maximum Operating Limits:

seal
250ºF (120ºC) with high

temperature seal.
Working Pressure: 75 PSI with standard seal

125 PSI with optional seals.
Starts per Hour: 20, evenly distributed.

1.7. Regular inspection and maintenance will increase

service life. Base schedule on operating time. Refer
to Section 8.

2. INSTALLATION

2.1. Locate pump as near liquid source as possible (below

level of liquid for automatic operation).

2.2. Protect from freezing or flooding.

2.3. Allow adequate space for servicing and ventilation.

2.4. All piping must be supported independently of the

pump, and must “line-up” naturally.

DESCRIPTION and SPECIFICATIONS:

The Model MCC is a close coupled, end suction, cen­trifugal pump for general liquid transfer service, booster
applications, etc. Liquid-end construction is cast iron and
AISI Type 316 stainless steel. Impellers are fully enclosed,
non-trimmable to intermediate diameters.

All units have NEMA 48Y or 56Y motors with square
flange mounting and threaded shaft extension.

Never draw piping into place by forcing
the pump suction and discharge connec-

tions.

2.5. Avoid unnecessary fittings. Select sizes to keep fric-

tion losses to a minimum.

2.6. Units may be installed horizontally, inclined or verti-

cally.

Do not install with motor below pump.
Any leakage or condensation will affect

the motor.

2.7. Foundation must be flat and substantial to eliminate

strain when tightening bolts. Use rubber mounts to
minimize noise and vibration.

2.8. Tighten motor hold-down bolts before connecting

piping to pump.

3. SUCTION PIPING

3.1. Low static suction lift and short, direct, suction pip-

ing is desired. Consult pump performance curve for
Net Positive Suction Head Required.

connection of the pump. Smaller size will degrade
performance.

3.3. If larger pipe is required, an eccentric pipe reducer

(with straight side up) must be installed at the pump.

3.4. Installation with pump below source of supply:

3.4.1. Install full flow isolation valve in piping for

inspection and maintenance.

5. ROTATION

5.1. Correct rotation is right-hand (clockwise when

viewed from the motor end). Switch power on and
off quickly. Observe shaft rotation. To change rota­tion:

5.1.1. Single-phase motor: Non-reversible

5.1.2. Three-phase motor: Interchange any two

power supply leads.

Do not use suction isolation valve to
throttle pump.

3.5. Installation with pump above source of supply:

3.5.1. Avoid air pockets. No part of piping should be

higher than pump suction connection. Slope
piping upward from liquid source.

3.5.2. All joints must be airtight.

3.5.3. Foot valve to be used only if necessary for

priming, or to hold prime on intermittent
service.

3.5.4. Suction strainer open area must be at least

triple the pipe area.

3.6. Size of inlet from liquid source, and minimum

submergence over inlet, must be sufficient to prevent
air entering pump through vortexing. See Figures 1
through 4.

3.7. Use 3 to 4 wraps of Teflon tape to seal threaded con-

nections.

4. DISCHARGE PIPING

4.1. Arrangement must include a check valve located

between a gate valve and the pump. The gate valve
is for regulation of capacity, or for inspection of the
pump or check valve.

4.2. If an increaser is required, place between check valve

and pump.

4.3. Use 3 to 4 wraps of Teflon tape to seal threaded con-

nections.

6. OPERATION

Pumped liquid provides lubrication. If

pump is run dry, rotating parts will seize
and mechanical seal will be damaged. Do not operate
at or near zero flow. Energy imparted to the liquid is
converted into heat. Liquid may flash to vapor. Rotating
parts require liquid to prevent scoring or seizing.

6.1. Before starting, pump must be primed (free of air

and suction pipe full of liquid) and discharge valve
partially open.

6.2. Make complete check after unit is run under operat-

ing conditions and temperature has stabilized. Check
for expansion of piping.

7. MAINTENANCE

7.1. Ball bearings are located in and are part of the mo-

tor. They are permanently lubricated. No greasing
required.

8. DISASSEMBLY

Complete disassembly of the unit will be described. Pro­ceed only as far as required to perform the maintenance
work required.

8.1. Turn off power.

8.2. Drain system and flush if necessary.

8.3. Remove motor hold-down bolts.

8.4. Disassembly of Liquid End

8.4.1. Remove casing bolts (370).

8.4.2. Remove back pull-out assembly from casing

(100).

8.4.3. Remove impeller locknut (304).

Do not insert screwdriver between impel-

ler vanes to prevent rotation of close­coupled units. Remove cap at opposite end of motor. A
screwdriver slot or a pair of flats will be exposed. Using
them will prevent impeller damage.

8.4.4. Remove impeller (101) by turning counter-

clockwise when looking at the front of the
pump. Protect hand with rag or glove.

Failure to remove the impeller in a

counter-clockwise direction may damage
threading on the impeller, shaft or both.

8.4.5. With two pry bars 180 degrees apart and

inserted between the seal housing (184) and
the motor adapter (108), carefully separate

the two parts. The mechanical seal rotary unit
(383) should come off the shaft with the seal
housing.

8.4.6. Push out the mechanical seal stationary seat

from the motor side of the seal housing.

9. REASSEMBLY

9.1. All parts should be cleaned before assembly.

9.2. Refer to parts list to identify required replacement

items. Specify pump index or catalog number when
ordering parts.

9.3. Reassembly is the reverse of disassembly.

9.4. Observe the following when reassembling the liquid-

end:

9.4.1. All mechanical seal components must be in

good condition or leakage may result. Re­placement of complete seal assembly, when­ever seal has been removed, is good standard
practice. It is permissible to use a light lubri­cant, such as glycerin, to facilitate assembly.
Do not contaminate the mechanical seal faces
with lubricant.

9.4.2. Inspect casing O-ring (513) and replace if

damaged. This O-ring may be lubricated with
petroleum jelly to ease assembly.

9.5. Check reassembled unit for binding. Correct as

required.

9.6. Tighten casing bolts in a star pattern to prevent O-

ring binding.
