Subassemblies

The sampler consists of three major subassemblies: the electronics enclosure, the refrigerator, and the wetted
parts. As a unit these subassemblies form an environmentally resistant enclosure.

Electronics Enclosure

The electronics enclosure includes the microprocessor-based controller, the
peristaltic pump, and the liquid sensor. Constructed of structural resin, the
enclosure conforms to Nema 4X,6 requirements when latched.

The Controller

The controller electronics consists of 1 board. The board converts outside
power to the appropriate internal use and controls the input/output signals
associated with the sampler. The CPU board contains a Z180 microprocessor,
RAM and ROM memory, and interfaces for the keyboard, and the display. The micro board also contains the
logic for the liquid sensor and the RPM counter. The user communicates to the sampler via a 24 key multiple
function membrane switch. The keys are clearly marked with their designated functions. An internal battery
maintains the program logic, RAM memory, and the controller's real-time clock and date function. T he
electronics are mounted on the back of the controller.

INSTALLATION AND OPERATION MODEL YB8

Peristaltic Pump

The Manning Model YB8 employs a high speed, dual
roller, vertically mounted, peristaltic pump. The pump is
belt driven by a 12VDC industrial grade motor. T his
ensures quite, smooth performance even while the unit is
subjected to very intense performance conditions. It
utilizes a face plate constructed of clear PVC for easy
visual identification of pump parameters, such as tube
alignment, and spindle and roller operation. The pump
body is made of impact and corrosion resistant Delrin
plastic for long life. It securely holds the pump tubing in
place by firmly clamping the two halves of the pump
case together. The pump is capable of vertical lifts of up
to 28 feet and produces sample transport velocities of

2.0 feet per second over a wide range of draw heights

Liquid Sensor

®

Figure 3 - Keypad

The Model YB8 utilizes a liquid sensor, located near
the entrance to the peristaltic pump, which is capable of
detecting the presence of source fluid as it approaches
the pump inlet. The sensor is either a continuity type
probe (base) or an ultrasonic sensor (optional).
The liquid sensor is used for two reasons.It enables the
sampler to rinse the intake line. After the initiation of a
sampling sequence the first operation is to turn on the
peristaltic pump. The pump begins rotating
counter-clockwise causing air to be forced out of the
intake tubing. After the set amount of purge time has
elapsed, the unit will reverse the pump so the rollers are
moving in a clockwise direction. This creates vacuum in
the pump tube, which in turn causes the source liquid, to
begin traveling up the intake line. As soon as the fluid
reaches the liquid sensor, the sampler will immediately
recognize that fluid has reached the inlet to the pump. It
will instantaneously reverse the direction of the pump
(rollers will be moving in a counter-clockwise rotation),
sending the water that had been drawn up back out of
the intake line. This in effect rinses the line. When the
unit has performed the set number of rinses, a sample
will be drawn. The rinse option is set in *99
(configuration mode). The sampler can be programmed
to not rinse the line or to rinse the line up to 3 times.

Figure 2 - Pump Assembly

Figure 4 - Liquid Sensor - Continuity Type

It makes it possible for the sampler to deliver precise, repeatable samples even in changing lift conditions.

Page A-4

April 1999/Manning Environmental Inc.

MODEL YB8 INSTALLATION AND OPERATION

Whenever a sampling sequence is initiated the sampler follows the steps outlined above, and draws a sample.
The controller then determines the transit time of the sample to reach the liquid sensor. Assume for example
there was an increase in the amount of lift from the source liquid to the unit. This would increase the time
needed for a sample to reach the liquid sensor and the pump. The controller, in a case such as this, will
automatically compensate for the change in lift by increasing the amount of time the peristaltic pump is able
to pull source liquid. This ensures the sampler has enough time to collect the correct amount of sample fluid.
The compensation applies to either an increase or decrease in lift height.

Refrigerator

The refrigerator is an industrial grade unit with the ability t o cool and maintain
samples at the EPA recommended 4ºC. Modifications have been performed on the
refrigerator that enable it to withstand event the harshest environments. The
condenser has been baked dip-coated with enamel and the copper refrigerant lines
are coated with asphalt cork tape to prevent hydrogen sulfide gas from attacking
the copper lines and the brazed joints. The thermostat is located inside the
refrigerator which affords it additional protection from the environment. The
evaporation coils and cabinet both have two coats of baked on acrylic enamel with
the cabinet having the additional protection of an iron phosphate pre-treatment.
Both the fan motor and t he compressor are designed for greater durability and
resistance to atmospheric attack. The unit boasts extensive insulation for
maximum cooling retention, and a full perimeter magnetic door gasket with a
urethane coating to resist corrosion and seal the cold inside. The door is also
available with an optional locking hasp to prevent unauthorized entry. The sample containers, suspension
plate, and distributor arm for multiple bottle operation are located within the environmentally controlled
chamber of the refrigerator.

Figure 5 - Refrigerator

Wetted Parts

Wetted parts are those pieces of the sampler that come in direct contact with the sample liquid. The main
components of the wetted parts for the Manning Model YB8 are the intake hose and strainer, the pump
tubing, the discharge tubing, the bottle full sensor (in single bottle units) the distribution assembly (in multiple
bottle units) and the sample bottles. If the source liquid t o be sampled is a non-priority pollutant (Non­Toxic) then all parts that touch the liquid are either PVC (Polyvinyl Chloride), medical grade silicone rubber,
ABS (Acrylonitrile Butadiene Styrene) plastic, or Stainless Steel. Parts in contact with a sample source that
is a priority pollutant (Toxic) are required to be Teflon , glass, stainless steel, or medical grade silicone

®

rubber. These materials are recognized and accepted as non-contaminating materials. This permits the
sampling of a wide variety of toxic pollutants such as hydrocarbons and chlorine-based compounds.

Intake Hose

The 3/8" ID by 5/8" OD intake hose is constructed of either PVC (Polyvinyl
Chloride) or PTFE. Y ou can differentiate the hoses by
their physical characteristics. The PVC is flexible and slightly tacky to the
touch. T he PTFE is not very flexible and is also very
smooth and slick to the touch.

INSTALLATION AND OPERATION MODEL YB8

Bottle Full Sensor

Strainer

The 3/8" ID strainer is available in stainless steel, or PVC. By placing
holes no larger than 3/8" ID along the length of the strainer, the intake of
large particles that can plug the hose or any part of the sampler is
prevented. Since the strainer is also weighted, it keeps the hose inlet at the
desired level in the source liquid.

Pump Tubing

The pump tubing Manning Environmental Inc. supplies for the Model
YB8 is medical grade silicone rubber.

Discharge Tubing

The 3/8" ID by 5/8" OD discharge tubing is also medical grade silicone rubber.

The bottle full sensor is only used on single bottle applications. It is a
cylinder, with a hole in the middle, to allow the discharge tube to pass
through. Constructed of PVC it has two stainless steel rods that protrude
vertically downward from the main body of the sensor. The user positions
the bottle full sensor in the container with the ends of the rods at the highest
point water should be allowed t o rise. O nce the water level has risen and
contacts the rods, a change in continuity is detected alerting the sampling
unit that the liquid in the container has reached the maximum level allowed by the user.
This ends the sampling cycle

Assembly

Assembling the Model YB8 Sampler

The unit is normally shipped assembled with accessories packed inside the refrigerator.

Refrigerator

There are several things to keep in mind before installing the refrigerator. T he location is important.
It is best to locate the unit out of direct sunlight and away from heat sources. It is best to locate the
unit at least two inches away from any kind of wall. Ventilation is required from the bottom front
section of the unit. Keep this area open and clear of any obstructions. It is recommended not to use
a power cord to power the unit. It is best if the unit can be plugged directly into the appropriate
power supply outlet. The refrigeration system is equipped with a power supply cord that has a three­pronged grounded plug. It must be plugged into a mating grounding type receptacle in accordance
with the National Electrical Code and applicable local codes and ordinances. If the circuit does not
have a grounding type receptacle, it is the responsibility and obligation of the customer to exchange
the existing receptacle in accordance with the National Electrical Code and applicable local codes an
dordinances. Th ethird ground prong should not under any circumstances, be cut or removed. All
U.L listed refrigerated products are equippedd with this type of plug, except hazardous location
models which are to wired to comply with the National Electrical Code, Article 501-4 for Class I
Divisions 1 and 2

Things to remember about the refrigerator:

A. Allow 24 hours for your refrigerator to reach a new temperature setting.

B. The motor will start and stop often. I t must do this to maintain the temperature you

select.
C. Keep you refrigerator as level as possible
D. Unplug the refrigerator before working on anything with the electrical system.
E. Exercise caution when sweeping, vacuuming or mopping near the front of the unit.

Damage to the grill can occur.
F. For all cleaning of the refrigerator, mix 2 tablespoons baking soda into 1 quart warm

water or use mild soap. D o not use strong cleaners or scouring powders or pads.
G. Keep all flame or sparks away from flammable material storage refrigerators when

opening the door to remove or store commodities.
H. Disconnect electrical power before removing electrical plug

Unpack the refrigerator by removing the bands at the top and bottom of the refrigerator box and
lifting the box off of the refrigeration unit. Open the refrigerator door and check for various
components that might be inside the refrigerator. I t ems are often packed inside the unit to minimize
shipping space. Check the items you have received against the packing list. Call Manning
immediately if yo u cannot match the packing list to the items shipped. M anning strives for 100%
accurate shipments, but mistakes do happen, so please call Manning immediately if t here is a
discrepancy.

4. Plug the refrigerator in and begin the cooling the unit down. Manning recommends using a
water proof thermometer and a liter of water to monitor the temperature of the water within
the refrigerator. T his will give a more accurate representation of the actual temperature of the
samples once sampling begins. Y ou should allow at least 24 hours for the refrigerator to
reach a stable condition.

NOTE: Be careful not to scratch any painted surfaces. The surfaces are painted with corrosion

resistant paint. S cratches in the paint minimize this protection.

Electronics Enclosure

1. On top of the refrigerator there will be 4 screws inserted into 4 plus nut holes. Remove the
screws from the holes and set them aside in a safe place.

2. Place the electronics enclosure on top of the refrigerator so the holes in the PVC mounting
bars match up with the threaded inserts in the refrigerator. The front (latches are in the front)
should be facing the door of the refrigerator and the peristaltic pump should be on the right.

3. Insert the screws and tighten snugly.

4. Thread the discharge tube into the center hole in the refrigerator. There
will be a black rubber plug that fits into the discharge hole. T his plug is
split to accept either the bottle full sensor cable or the stepper motor
cable depending on the configuration that you ordered. The cable fits
inside the plug.

4. Mate the black connectors. ( Applying non-conductive grease will help if d isassembly
is required later.)

There are wire racks inside the refrigerator so the distribution assembly can be parked out of the way when
removing the suspension plate and/or bottles. This makes it unnecessary to remove the discharge tube from
the spout union or to de-mate the connector when removing the plate.

Spout Position

If the suspension plate was removed from the refrigerator,
replace it. Place the spout over the last bottle in the series,
since the first action of the sampling cycle is a spout
advance.

Installing The Sampler

Install the sampler on a firm, level surface adjacent to the sampling point. If the sampler is installed outdoors,
consider enclosing it in a shelter or under some sort of protection. T his will improve the performance and life
of the unit. The Manning Parts Department can supply an optional full-size NEMA 3R insulated fiberglass
enclosure designed for this purpose.

Connecting Power

The YB8 sampler was designed with components which operate on 12 VDC power. Recognizing
that 115 VAC power has to be available to run the refrigerator, the sampler takes advantage of the
constant supply by employing an AC/DC converter to provide power to the system. The converter is
located inside the electronics enclosure. It comes equipped with a power cord, but it can be hard
wired if desired. A power switch, which controls flow of current to the controller and peristaltic

INSTALLATION AND OPERATION MODEL YB8

pump, is located on the front of the electronics enclosure. The refrigerator has its own individual
power cord. By using the AC/DC converter the user does not have to be concerned with replacement
of batteries, charging of batteries, or any other factors which affect 12 VDC systems. The system has
been thoroughly tested using 115 VAC and will provide outstanding service, reliability, and longevity.
To power t he unit up follow these simple steps:

1. Check to make sure that the pump cover is
securely fastened to the pump housing and that
the unit is ready to be powered up.

2. Locate the power plug coming out of the
electronics enclosure.

3. Plug the AC/DC converter into the appropriate
receptacle.

4. Turn the power switch, located on the right side
of the electronics enclosure, to "ON". Verify, by
looking at the display, that power is being
applied to the system. If the display does not light up, confirm that the appropriate
connections have been made. I f the unit does still not power up, call the Manning Service
Department. T hey will be able to provide assistance in getting the unit operat ional.

WARNING: Hard-wiring should only be done by a certified electrician.

Sample Intake Line

Attach the intake hose to the connector at the end of the pump tubing.

Intake Hose Placement

Place the intake hose strainer directly in the channel flow, not in an eddy or at the edge of the flow.
In channels with debris, provide deflection to prevent clogging of strainer holes. The weight supplied
with the intake hose is usually sufficient to prevent the intake from being pulled to the surface of a
fast channel.

The correct vertical position of the strainer depends on the type of sample being taken. Placing the
strainer at the bottom of the flow results in a heavier concentration of solids in the sample, while
placing the strainer at or near the top of the flow results in heavier concentration of oils, fats, and
other floating or suspended contaminants.

The intake hose should be positioned so the hose can drain between sample cycles and no low spots
exist which would trap water. The correct and incorrect hose placements are shown below.

Running A Test Cycle

While it is not mandatory to run a test cycle, it is recommended to assure proper operation and to become
familiar with the various functions and modes of operation. Run a test cycle before programming any
operational modes into the sampler.

1. Turn the main power switch to the “ON” position. The display should read “Sampler Ready”.

2. If the multiple bottle option is being used, rotate the spout so it is over a bottle.

3. Submerge the strainer of the intake hose in a container of clean water. The amount of water
should be enough to keep the strainer covered completely for several test cycles.

4. Press the TEST CYCLE key on the keypad to initiate the test cycle. Y ou will be prompted
for the number of samples you want to take. Enter the number and press <ENTER>.

The Sampling Cycle

Refer to the errata (pages 9-11) at the end of this manual for sampler theory of operation.

There are two types of sample events. The first is time-based. In this type a time interval is defined and the
sampler places a sample in each bottle based on that time interval.

The second type of sample event is flow-based. In this type an external flowmeter provides one of two types
of signals: a contact closure when a specified amount of liquid has flowed past the measurement point; with
the analog option, an analog signal proportional to flow rate.

April 1999/Manning Environmental Inc.

Page A-15

INSTALLATION AND OPERATION MODEL YB8

Whether the sample event is triggered by a flowmeter or by a time interval, the actual sampling cycle is the
same. For the multiple bottle option, the first action is the advance of the spout to the next bottle. (For single
bottle samplers, this step is omitted.) Next, the sampler turns on the peristaltic pump. The pump begins
rotating counter-clockwise causing air to be forced out of the intake tubing. This clears the intake hose of
any contents or obstructions that may inhibit proper sample collection. After the set amount of purge time
has elapsed, the unit will then reverse the pump so that the rollers are now moving in a clockwise direction.
This causes vacuum to be created in the tube, which causes the source liquid, to begin traveling up the intake
line. I f the unit was programmed to rinse, as the source liquid rises in the intake line it will reach the liquid
sensor. T he sampler will immediately recognize that fluid has reached the inlet to the pump. It will
instantaneously reverse the direction of the pump (rollers will be moving in a counter-clockwise rotation),
sending the water that had been drawn up back out of the intake line. This in effect rinses the line. If the unit
was not set for a rinse the above steps wil be ommited. U pon completion of the last rinse, source liquid will
again be drawn up the intake line. The system monitors the flow of liquid and when the preset amount has
passed through, the pump will reverse operation again (rollers moving counter-clockwise). T his purges
excess fluid out of the pump and clears the intake line. Depending on how the unit is programmed or
configured, after completing the post sample purge, the sampler will now stop operation or continue
performing those functions which it has been programmed. F or a complete description of programming the
sampler see the programming section in this manual.

If the multiple bottle option is being used, the distribution spout remains stationary until the next sample
event. This delay prevents cross-contamination of the next sample.

Sample Recovery

Immediate sample recovery is not required since the sampler will automatically shut down when the sample
container is full (single bottle only), a pre-set number of samples have been taken, or when the program is
complete. However, sample analysis may require quick recovery to maintain sample freshness or to add
chemicals.

If the intent is to leave the containers in the suspension plate, caps can be installed over the suspension
collars. Remove the suspension plate (with bottles) from the refrigerator. Lift the distribution assembly off
the suspension plate and place it on the wire racks mounted in the refrigerator.

It may be easier to remove the distribution assembly first, and then install the bottle caps. To seal the 350ml
glass bottles, replace cap liners, then place caps on bottles.

MODEL YB8 INSTALLATION AND OPERATION

External Connections

Refer to the errata (page 3) for more information on connecting to an external device.

DANGER: Turn the sampler off at the power switch and unplug the power supply before

making connections. Injury can result if the power is present when making
connections.

The following chart describes the external connections which are necessary to operate the sampler:

Contact In & Analog In Connections

Purpose Connector Designation Color Polarity

Contact In A Red No Polarity

Contact In B Black No Polarity

Analog In (+)

Analog In ( - )

Bottle Full/Stepper Motor

The Model YB8 can utilize both a Bottle Full Sensor and Stepper Motor (not at the same time).
Connections for the Bottle Full Sensor and the Stepper Motor are hardwired to the unit. If the unit was
purchased as a single bottle unit only, the wires for multiple bottle operation are not run. If multiple bottle
operation is desired, a conversion of the unit to multiple bot tle operation will need to be done at the factory.
To connect them follow the instructions listed below:

D White Positive

C Green Negative

A) Locate the cable comming out of the bulk head fitting on the left front of the electronics

enclosure. It runs down through the top of the refrigerator. For single bottle units, there are two

female contacts on the end. For multi-bottle units, there is a black connector.

Contact Closure

This enables the sampler to accept a contact closure from, an external device. The parameter to be measured
is set, recorded, and totalized by the external device. When the set limit is met, a contact closure will be sent to
the sampler. T his in turn will initiate the sample collection process.

The sample comes standard wtih a 3 foot cable for connecting to external devices.

To connect the external device to the sampler follow the steps listed below:

A) Locate the connector on the left side of the electronics enclosure.
If the sampler has the Analog Option, it will be labeled Contact In/Analog In.

B) Wire the red and black wires to the external device's contact closure output.

C) Re-connect the cable to the connector on the enclosure.

This should complete the installation of the contact closure. Test the connection by
initiating a closure through the external device to verify the wiring is correct and the
sampler is initiating a sampling cycle when a closure is received.

In/Analog In Cable

Analog Signal (Optional)

With this option, the sampler can accept an external 4-20mA signal from an external device. The flow
volume is internally totalized by the sampler*s controller. The analog option is not available as a field retrofit.
Contact the Manning Parts Department to discuss a factory modification. To connect the external device to
the sampler follow the steps listed below:

A) Locate the connector on the left side of electronics enclosure which is labeled "Contact/Analog In".

MODEL YB8 INSTALLATION AND OPERATION

B) Wire the white (+) and green (-) wires to the external device’s analog output.

C) Re-connect the cable to the "Contact/Analog In" connector.

This should complete the installation of the contact closure. Test the connection through the external device
to verify the wiring is correct and the sampler is initiating a sampling cycle when the signal is received. See
the *08 Mode in the Programming section for additional information.

This completes the installation of the sampler. The unit should now be operational. Proceed to the
programming instructions to program the sampler for operat ion.
