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 lo gic, RAM memory, and t he controller's real-time clock and date function. T he
electronics are mounted on the back of the controller.

Figure 2 - Pump Assembly
Figure 3 - Keypad
Figure 4 - Liquid Sensor - Continuity Type
The Manning Model YB8 employs a high speed, dual
roller, vertically mounted, peristaltic pump. The pump is
belt driven by a 12VDC industrial grade mo tor. 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
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, t he 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 o f the pump
(rollers will be mo ving 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. T he rinse o ption 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.
It makes it possible fo r t he sampler to deliver precise, repeatable samples even in changing lift conditions.
Peristaltic Pump

MODEL YB8 INSTALLATION AND OPERATION
April 1999/Manning Environmental Inc. Page A-5
Figure 5 - Refrigerator
Figure 6 - Intake Hose
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 t he 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 the 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.
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 t he sample bottles. I f the source liquid t o be sampled is a non-priority pollutant (Non-
Toxic) t hen 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 t he 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.

Figure 7 - Strainers
Figure 8 - Pump Tubing
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.
®
Bottle Full Sensor
The bottle full sensor is o nly used o n single bottle applications. I t 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 t hings to keep in mind before installing t he refrigerator. T he lo cation 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 three-
pronged 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 t he customer t o 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 mo tor will start and stop often. I t must do t his t o maintain t he t emperature yo u
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 t o t he grill can o ccur.
F. For all cleaning of the refrigerator, mix 2 tablespoons baking soda into 1 quart warm
water o r use mild soap. D o not use strong cleaners o r scouring powders o r 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 tems are o ften packed inside t he unit t o minimize
shipping space. Check the items you have received against the packing list. Call Manning
immediately if yo u cannot match t he packing list to t he it ems shipped. M anning strives fo r 100%
accurate shipments, but mistakes do happen, so please call Manning immediately if t here is a
discrepancy.

Figure 12 - Refrigeration Hole Placement
1. Once you have unpacked the unit, locate the four feet
for the refrigerator (they are in a small plastic bag inside
the refrigerator, with the refrigerator owners manual).
2. With the refrigerator empty, carefully tip it and screw a
foot into the threaded hole in the bottom of each
corner.
3. Adjust the feet so the refrigerator is level and does not
rock.
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 mo re accurate representation of the actual temperature of the
samples o nce sampling begins. Y ou should allow at least 24 hours fo r t he 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 t he paint minimize this protection.
Electronics Enclosure
1. On top of t he refrigerator there will be 4 screws inserted into 4 plus nut holes. R emove 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 fit s into t he 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.

Single Bottle Sampling
1. Center the sample bottle in the refrigerator.
2. Run the discharge hose through the Bottle Full sensor ring and then place it at the
desired height in t he bottle. T o adjust t he position simply slide t he bottle full
sensor either up or down the discharge hose.
3. Connect the Bottle Full sensor probes to the female contacts on the bottle full
cable comming from the electronics enclosure into the refrigerator.
Multiple Bottle Sampling
Suspension Plate Installation
Position the suspension plate so the handles are on the sides. Slide the plate onto the top
rails in the refrigerator. The plate should be flush with the front of the refrigerator so it
does not interfere with the drain trough in the rear.
Distributor Assembly
1. Verify t hat the spout is correctly aligned on the distribution bracket. The spout should be centered
on the bracket side when the spout is rotated to the side (3 o'clock position).
