INSTALLATION
BF Series Down and Back Draft Workstation Installation Instructions
Locate package of smaller items (dissection board, tissue boxes, or filters)
When removing from the shipping platform, be careful if the unit has a foot pedal. The unit should be removed from
the shipping platform as to not cause damage to the copper plumbing attached to the foot pedal
Leveling and Setting Unit in Place
The unit should be off the floor and resting on the leveling pads. The unit should be leveled to ensure proper drainage.
This allows water to evaporate or dry in case of a leak without getting trapped by the base of the unit Ensure there is a
Minimum of 6.5” from the wall to the back of the unit. This allows for elevating units to move freely without any
obstructions to the wall.
Utility Connections
The only connections necessary are the Electric, Cold and Hot water supply, the drain connection and the HVAC
connections if in house ventilation. The unit is already pre-wired and plumbed for the options ordered.
Electrical Connection
All electrical, water and ventilation stubs should be prepared in accordance with our rough-in dimensions shown on
rough in diagram from your approval process.
The electrical service provided for the MB600 must include:
1) A switch or circuit breaker for each circuit to which the wiring harnesses from the workstation will be
connected.
Each BF Series Workstation has a eight-foot line cord with a hospital grade plug. It is possible to order with a 3 foot
whip to permanently hard wire the unit to the electrical connection. The whip leads are labeled L1 and C1 for the unit
electrical options such as lights and fans if a recirculation unit.
There are three wires:
Black Labeled as L1
White Labeled as C1
Green w Yellow Stripe Ground
Flexible water tight conduit and connections are the preferred conduit and is not provided with the unit. This is due to
an unknown length needed and variances possible in the rough in process.
Drain Connection
The BF500, BF510 and BF550 workstations are equipped with 1.5” Diameter drain and connections. DO NOT modify
the drain line or connections without contacting MOPEC first. The Units are built in accordance with the rough in
drawings specific to the unit. The height is per the rough in drawings provided at the time of the order.
Water Supply Connection
The water supply connections are ½” DIA copper pipe. The unit has been cleared of water and debris during the
manufacturing and testing of the unit. The rough in drawing for the unit suggests a 1/4 turn valve to be connected to
the wall. This is to allow the water to be localized and disconnected should the need arise to work on plumbing in the
future. Before connecting the unit to the facility water supply, check the lines in the facility for debris by flushing the
lines for a moment. After the connections are made remove the aerator from the faucet and turn the water on and
open the faucet and other water options after the faucet to allow any debris to evacuate the system. This is the time
to look for leaks or other plumbing issues. The plumbing is tested for leaks and function at the facility and is put under
pressure for 45 minutes to check for leaks. However, the plumbing is hard copper and soldier connections. During
transport a unit may experience a failed soldier joint. Contact MOPEC immediately if there is a leak.

Ventilation Connection
Ventilation is one of two types for the BF Workstations; In House Ventilation or Recirculation. For in house the unit is
connected to the facility ventilation system via duct work.
In House
BF450 the connection is a 4” x 18” rectangular stub on the top back of your unit. The duct work is not provided by
Mopec unless specifically ordered.
MB550 the connection is a 4” x 18” rectangular stub on the top back of your unit. The duct work is not provided by
Mopec unless specifically ordered.
Recirculation
BF400, BF500 and BF510 the filters will need to be installed. You should have a minimum of 2 inches or more behind
the workstation for the filtered air to discharge. Air flow is generated by multiple fans in the recirculation models. They
are controlled by a rheostat to control volume/speed.
The ventilation diverter should be placed no more than 15CM (Approx 6” from the front/ Please see the photo below.
The grid plate must be installed with the holes to the back and the finger holes to the front as shown below
The next step is to open filter access door (it the unit is a recirculating air unit) by unlatching both side latches pivoting
the access door open and removing filters.
Each filter can be removed simply by pulling it toward you and out of the module. Both the activated charcoal filters
are wrapped in plastic and must be removed before installation. You may notice some loose charcoal particles due to
transportation which is normal.
Once the plastic is removed slide the filter in the slot and close the door.
** Caution ** These are general guidelines and installation is specific for each of the BF Series units. Professional
installation is recommended.

System and a large lighted work area.
BF510 is a Portable Grossing Station with a Recirculation Ventilation System, a Hand Spray Rinse
System and a large lighted work area.
The BF400 and BF500 workstations are designed with a down and back draft ventilated work surface.
The design allows air to flow through the grid plate. The BF400 is designed with a catch pan to collect fluids if
necessary while the BF500 is freestanding with a built-in drain connection that fluids can flow directly into
the drain.
The BF400 is designed to fit onto a standard countertop. The BF500 is free standing complete with
drain connection. The BF Series air flow is achieved in one of two ways; the unit can be connected to the
ventilation system of the facility or with the built-in fans and filters.
The blower motor must be turned on with the red switch next to the fan speed control. The variable speed
fan is operated by turning the control to 100 and turning the knob to the desired speed. This allows the fan
to attain its full speed and then adjust to the requested speed.

AIR HANDLING
BF Series Back and Down Draft Workstation Design Parameters:
The BF Series Workstations are designed with the basis of fulfilling one goal and that is to adequately ventilate the
work surface. An adverse effect of ventilation is noise that has been considered but does not govern the ultimate
design criteria. Our design criteria are the most stringent utilizing exerts as outlined from “Industrial Ventilation” by
Committee on Industrial Ventilation and Escape Velocity Parameters. Design data is unfortunately based on the table
as a completely flooded vat of formaldehyde. Ideal conditions in a grossing environment obviously do not warrant such
a large amount of formaldehyde, yet concentration levels are on a higher extreme regarding design data parameters
available. Therefore, assumptions are made regarding grossing practices and ultimately formaldehyde concentrations.
Two (2) blowers are supplied with the BF400, BF500 and BF510 are designed with an adjustable control to regulate the
speed and consequentially the airflow. The BF450 and BF550 workstations are in house ventilation and do not have
blowers or filters With all the above considered, below is a chart of actual ventilation parameters for MB Series
Grossing Workstations along with their respective definitions:
Identification Description Ventilation Volume
System Requirements
BF400 Down and Backdraft workstation Re-circulating 300 cfm
BF450 Down and Backdraft Workstation In-House 300 cfm
BF500 Down and Backdraft workstation Re-circulating 300 cfm
BF510 Down and Backdraft workstation Re-circulating 300 cfm
BF550 Down and Backdraft Workstation In-House 300 cfm
a Re-circulating (Self-contained exhaust Systems): This system is simply a self-contained exhaust system provide with
the Workstation. Air is ventilated through the exhaust grill and circulated through potassium permanganate filters and
exhausted out the back of the Grossing Workstation. The exhaust fans are internal and are provided.
The grill for the MB600 is 8” high at an angle of 60 Degrees and 48” Long with (994) 3/16” x 5/8” holes.
The vent grill is perforated with 3/16” x 5/8” slots on 13/16” x 3/8” staggered centers, yielding a 30% open area.
b Both specifications for Fan 1 and Fan 2 are “Free Air” cfm.
When connected to the building ventilation system, volumetric flow rates should be adjustable and be between 300
and 350 CFM (Cubic Feet per Minute. This variable will allow the user a means of adjusting the airflow to their comfort
level and work conditions. Calculations are based on 125 LFM (Linear Feet per Minute) face velocity through the grid
plates. It should be noted that the working environment is totally open therefore existing room conditions and air
currents have a serious effect on the efficiency of the ventilation.
The design parameters for the BF Series Workstations are suggested ventilation requirements and are based on
stringent ventilation requirements and ideal conditions. Personalized conditions and practices may warrant an increase
or decrease of the ventilation
GOOD PRACTICE WILL OPTIMIZE OUR PROTECTION:
1. Never block the ventilation grill.
2. Placing open containers as close to the exhaust grill as possible, yet never blocking the ventilation grill.
3. Grossing should be accomplished as close to the exhaust grill as possible.
4. Strategically locate the Grossing Station away from room air currents.
5. Practice complete rinsing of residual formaldehyde with hand held spray.
Although the Mopec Grossing Workstation can be the answer to formaldehyde exposure, Mopec cannot assume
responsibility of exposure since good laboratory practices and room conditions are beyond Mopec’s control.

CLEANING AND MAINTENANCE
EVALUATING FILTERS FOR REPLACEMENT
The filters in your MB unit contain alumina pellets impregnated with potassium permanganate, KMnO4, which is a fast
oxidizer. Formaldehyde passing through the filter is converted to carbon dioxide and water. The filter’s life depends
entirely on the amount of formaldehyde fumes passing through the filter.
The pellets are bright purple when new and become dark brown when spent. Once the inner part of the pellet is
brown it is totally spent and must be replaced.
This chemistry is very effective and essentially removes all formaldehyde as long as there is active KMnO4 available.
The efficiency drops off as the filter media approaches its maximum capacity. The last 15-20% capacity will exhibit
some pass through of formaldehyde.
PROCEDURE - EVALUATING FILTERS FOR REPLACEMENT
One side of the filter will have a small tab which can be opened just enough to allow one or two pellets to be removed.
(See photo)
To determine when the KMnO4has been exhausted, remove a pellet and slice it in half.
Eye protection is recommended based on the above “Health Hazard Data”.
The usefulness of the filter is approximately 80% diminished when the purple color
first disappears from the core.
The filter saturation rate depends on hours of operation and fumes to be filtered.
Instructions on how to change and check the saturation of the filters
Place the sliced pellet(s) on a paper towel and add a few drops of water. The water running off the pellet(s) should be
initially purple and then turn a deep iodine color. If no purple coloration is present, the KMnO4(Potassium
Permanganate) material is totally spent.
When the purple color first disappears from the core of the pellet as described above, the rate at which
formaldehyde is removed from the air stream is slowed considerably.
(See Summary on Following Page)
PROCEDURE –SUMMARY OF EVALUATING FILTERS FOR REPLACEMENT
From a practical standpoint, it may be desirable to perform the tests on the preceding page more frequently during
initial usage of the filters to determine when the purple first begins to disappear from the core of the sliced pellet.
Based on these early observations, the user can establish a Replacement Testing Cycle with occasional re-checks for
verification. Filter Evaluation Video Link
The filter saturation rate depends on hours of operation and fumes to be filtered. Instructions on how to change and
check the saturation of the filters are shown in the following links
Dispose of contaminated filters in accordance with your facility, state and federal procedures for hazardous materials
disposal. See the SDS for the chemicals exposed to the filters for directions.
Health Hazard Data - Alumina Permanganate Filter Media
Effects of Exposure –The filter media is non-toxic upon oral, skin, and inhalation exposure and is non-irritant of the
skin. Breathing of dust may cause sneezing. Skin may feel dry after contact. The filter media is an eye irritant.
Emergency Treatment –Flush eye with large quantities of water and seek medical attention.
