1.2 QuickStart Mounting
1.2.1 Transmitter/Antenna
1. The device is manufactured as one unit that includes the
transmitter and antenna.
2. Remove any protective material from the antenna before
installing.
3. Install the transmitter/antenna into the process connection.
If threaded, tighten securely by hand using the housing for
grip. Ensure there is no cross-threading and do not over
tighten as this may cause damage to the plastic threads.
4. Adjust the beam position by turning the internal launcher
adjustment (Fig ??). The internal launcher adjustment is
numbered 1-18 that equates to 10-180 degrees of adjust-
ment; 9 is the midpoint where long axis of the beam is at
45 degrees to the Display (Fig ??). After positioning the
transmitter display, rotate the launcher adjustment so the
beam is at an angle of 45° to a line from the radar unit to
the nearest tank wall (Fig ??). Do not optimize the Quality
(signal strength) at one level in the vessel.
• Do not place insulating material around any part of the
Radar transmitter including the antenna process connection.
1.3 QuickStart Wiring
NOTE: Make sure the electrical wiring to the R82 radar transmitter is
complete and in compliance with all regulations and codes.
1. Remove the cover of the wiring compartment.
2. Attach a conduit fitting and mount the conduit plug in the
spare opening. Pull the power supply wire through the con-
duit fitting.
3. Connect shield to an earth ground at power supply and
leave floating at the transmitter.
4. Connect the positive supply wire to the (+) terminal and the
negative supply wire to the (-) terminal. For Explosion

2.0 Complete Installation
This section provides detailed procedures for properly
installing, configuring, and, as needed, troubleshooting the
R82 Radar Level Transmitter.
2.1 Unpacking
Unpack the instrument carefully. Make sure all components
have been removed from the packing material. Check all the
contents against the packing slip and report any discrepancies
to the factory.
Before proceeding with the installation, do the following:
• Inspect all components for damage. Report any damage to
the carrier within 24 hours.
• Make sure the nameplate model number on the transmitter
agree with the packing slip and purchase order.
• Record the model and serial numbers for future reference
when ordering parts.
2.2 Electrostatic Discharge (ESD)
Handling Procedure
Magnetrol’s electronic instruments are manufactured to the
highest quality standards. These instruments use electronic
components that may be damaged by static electricity pres-
ent in most work environments.
The following steps are recommended to reduce the risk of
component failure due to electrostatic discharge.
• Ship and store circuit boards in anti-static bags. If an anti-
static bag is not available, wrap the board in aluminum foil.
Do not place boards on foam packing materials.
• Use a grounding wrist strap when installing and removing
circuit boards. A grounded workstation is recommended.
• Handle circuit boards only by the edges. Do not touch
components or connector pins.
• Make sure that all electrical connections are completely
made and none are partial or floating. Ground all equip-
ment to a good, earth ground.
10
2.3 Before You Begin
2.3.1 Site Preparation
Each R82 Radar transmitter is built to match the specific
physical specifications of the required installation. Make
sure the antenna connection is correct for the threaded or
flanged mounting on the vessel or tank where the transmit-
ter will be placed. See Mounting, Section 2.4.
Make sure that the wiring between the power supply and
Radar transmitter are complete and correct for the type of
installation.
When installing the Radar transmitter in a general purpose
or hazardous area, all local, state, and federal regulations and
guidelines must be observed. See Wiring, Section 2.5.
2.3.2 Equipment and Tools
No special tools are needed. The following items are
recommended:
• Threaded antenna and transmitter . . . . . . 2" (50 mm)
• Torque wrench . . . . . . . . . . . . . . . . . . . . . highly desirable
• Flat-blade screwdriver
• Digital multimeter or volt/ammeter . . . . . Optional
• 24 VDC (23 mA) power supply. . . . . . . . Optional
2.3.3 Operational Considerations
Radar applications are characterized by three basic conditions;
Dielectric, Distance (measuring range) and Disturbances
(turbulence, foam, false targets, multiple reflections and rate
of change).
2.3.3.1 Maximum Distance
The chart below shows the maximum measuring range
(Distance) of each antenna based on fundamental condi-
tions of Dielectric, Distance and Turbulence. Maximum dis-
tance is calculated as Tank Height + Sensor Offset
(see page 17). It is measured from the Sensor Reference
Point (bottom of NPT thread, top of BSP thread or face of
a flange).
2.3.3.2 Minimum Distance
If the liquid level is allowed onto the antenna, noise and
media build-up drastically decrease reliable measurement.
Liquid should not be allowed closer than 15 inches
(380 mm) from the bottom of the antenna mounting
threads (or face of sanitary flange).

2.3.3.3 Problematic Applications; GWR Alternative
Some application concerns can be problematic for Radar.
For these, Guided Wave Radar is recommended:
• Extremely low dielectric media (εr<2.0)
• Very weak reflections from the liquid surface, particularly
during turbulence, can cause poor performance.
• Tanks heavily cluttered with false targets (mixers, pumps,
ladders, pipes, etc.)
• During times of very low liquid levels of low dielectric media,
the metal tank bottom may be detected deteriorating per-
formance.

• Foam can either absorb or reflect the microwave energy
depending upon the depth, dielectric, density and wall
thickness of the bubbles. Due to typical variations in the
amount (depth) of foam, it is impossible to quantify per-
formance. It may be possible to receive most, some or none
of the transmitted energy.
• Extremely high liquid levels (Overflow) conditions when
liquid very near the antenna can cause erroneous readings
and measurement failure.
2.4 Mounting
The R82 Radar transmitter can be mounted to a vessel
using a variety of process connections. Generally, either a
threaded or flanged connection is used.
2.4.1 Installing the Antenna
Before installing, make sure:
• Process temperature, pressure, dielectric, turbulence and
distance are within the antenna specifications for the
installation.
• End of antenna is protected from bending or breaking.
• Insulating material is not placed around any part of the
Radar transmitter including the antenna flange.
• Antenna is being mounted in the optimal location. See fol-
lowing sections: Location, Beam Angle, Obstructions and
Nozzles for specific information.
2.4.1.1 Location
Ideally, the Radar transmitter should be mounted providing
an unobstructed signal path to the liquid surface where it
should illuminate (with microwave energy) the largest,
possible surface area. See Section 2.4.1.2, Beam Angle.
Unavoidable obstacles will produce reflections that must be
minimized during field configuration. See Section 2.6.5.1,
Target Rejection. Mount in a location equal to 1⁄2the radius
of tank top. Do not mount in center of vessel nor closer
than 10" (25 cm) of tank wall.
2.4.1.2 Beam Angle
The various antenna designs exhibit different beam patterns.
Ideally, the beam pattern should illuminate the maximum
liquid surface with a minimum striking other objects in the
vessel including the tank wall. Use these drawings to deter-
mine the optimum installation location.

58-610 Model R82 Radar Transmitter
2.4.1.3 Obstructions
Almost any object that falls within the beam pattern will
cause reflections that may be misinterpreted as a false liquid
level. Although Model R82 has a powerful False Target
Rejection routine, all possible precautions should be taken
to minimize false target reflections with proper installation
and orientation.
2.4.1.4 Nozzles
Improper installation in a nozzle creates “ringing” which
will adversely affect measurement. Refer to Figure 9???. Two
Antenna extension lengths are offered to allow the R82
transmitter to work reliably in a variety of nozzles.
The Minimum Blocking Distance of 15" (380 mm) is
always measured from the bottom of the threads or face of
a flange. The related distance as measured from the end of
the antenna varies depending on the antenna extension
chosen. See Figure ??.
The narrow beam width of the 26 GHz, R82 does allow
mounting so that the antenna can be recessed inside the
nozzle. Optimally, the recessed dimension should never
exceed 2×the nozzle diameter. See Figure??????
NOTE: If the antenna is recessed in a nozzle it is mandatory that Echo
Rejection is run to eliminate any possibility of false reflections.
14 58-610 Model R82 Radar Transmitter
2.4.1.5 Standpipes and Stillwells
The R82 can be mounted in a standpipe or stillwell but
certain considerations should be given:
• Metal stillwells only: 2" (Sched 40 max.) to 4" (50–100 mm).
• Diameter must be consistent throughout length; no reducers.
• Stillwell length must cover complete range of measurement
(i.e., liquid must be in stillwell).
• Welds should be smooth.
• Vents: holes <0.125" diameter, slots <0.125" width.
• If an isolation valve is used, it must be a full port ball valve
with an I.D. equal to the pipe diameter.
• Bridles/Bypass Installations: The launcher should be rotated
90° from process connections.
• Configuration must include an entry for PIPE I.D.
See Section 2.6.5.1, Item 34- PIPE I.D.
• There will be some increased dielectric sensitivity; system
GAIN will be reduced when PIPE ID >0.
2.4.2 Installing the Transmitter
Install the Transmitter with its integral antenna by threading
into the vessel. DO NOT OVERTIGHTHEN as this may
cause damage to the plastic threads.
• Do not place insulating material around any part of the
radar transmitter including the antenna flange.
• Installation for NEMA 6P/IP 68- the transmitter can be
installed to allow for temporary submergence to 6 feet (1.8m):
- use TFE paste to seal conduit entries and antenna process
connection
- Do not overtighten housing cover; O-ring develops
water-tight seal without excessive tightening
2.4.2.1 Orientation
The R82 transmitter utilizes a linearly polarized, microwave
beam that can be rotated to improve its performance. Proper
orientation can minimize unwanted target reflections, decrease
sidewall reflections (multipath) and maximize direct reflec-
tions from the liquid surface.
The internal launcher mechanism can be turned to optimize
performance. The launcher has index marks numbered
1–18 (representing 10–180 degrees). The Polarization
pattern is at 45 degrees to the transmitter display when
the mechanism is at the #9 position.

58-610 Model R82 Radar Transmitter
2.4.2.2 Initial Installation
Ideally, the transmitter should be mounted half the radius
from the tank wall. In a typical vertical tank, the Launcher
should be adjusted so the polarization pattern is 45 degrees
to the closest tank sidewall. See Figures ? & ?.
For horizontal cylindrical vessels, aim beam down the long
axis of the vessel. Do not optimize the Quality (signal
strength) at one level in the vessel.
A transmitter mounted within 10" (25 cm) of a tank wall
may demand orientation adjustments to limit multipath
and optimize performance. See Section 2.4.2.3, Poor Echo
Strength.
2.4.2.3 Poor Echo Strength
Poor signal quality has many potential causes. Following are
two initial areas for investigation.
Launcher Orientation: Initial launcher orientation is always
45 degrees (see Sections 2.4.1 & 2.4.2). In tall vessels and
when antenna is mounted close to the tank wall, improve-
ment in signal quality may be attained by rotating the
launcher to 90 degrees.
Signal Loss: If the Level signal is lost repeatedly at a specific
point in the vessel, it is usually a symptom that multipath
(side-wall reflections) are causing cancellation by returning
to the transmitter exactly 180° out of phase with the Level
signal. Utilize the following procedure:
• Go to transmitter screen #5 which shows both Level and
Echo Strength.
• Bring the Level up (or down) to the exact point where the
signal is repeatedly lost. Monitor the Echo Strength this
point is being approached. The Echo Strength will degrade
to a low point before it begins to increase.
• At the poorest Echo Strength slowly rotate the launcher
1–2 notches. Allow the unit to stabilize for approximately
one minute. Repeat this process until the Echo Strength is
optimized.

2.5 Wiring
Caution The R82 Radar transmitter operates at voltages of 16–36
VDC (GP) and 16-28.6 VDC (IS). Higher voltage will dam-
age the transmitter.
Wiring between the power supply and the Radar transmitter
should be made using 18–22 AWG shielded twisted pair
instrument cable. Within the transmitter enclosure, con-
nections are made to the terminal strip and the ground
connections. Trim excess wiring to minimize clutter, noise
issues and allow access to Launcher adjustment (see
Figure ??). The directions for wiring the Radar transmitter
depend on the application:
• General Purpose or Non-incendive (Cl I, Div. 2)
• Intrinsically Safe
NOTE: For ATEX installation guidelines refer to bulletin BE 58-610.
2.5.1 General Purpose or Non-incendive (Cl I, Div. 2)
A general purpose installation does not have flammable
media present. Areas rated non-incendive (Cl I, Div. 2) have
flammable media present only under abnormal conditions.
No special electrical connections are required. If flammable
media is contained in the vessel, the transmitter must be
installed per Cl I, Div. 1 standards of area classification.
To install General Purpose or Non-incendive wiring:
1. Remove the cover to the wiring compartment of the trans-
mitter. Install the conduit plug in the unused opening.
2. Install a conduit fitting and pull the supply wires.
3. Connect shield to an earth ground at power supply and
leave floating at the transmitter.
4. Connect an earth ground wire to the nearest green ground
screw per local electrical code (not shown in illustration).
5. Connect the positive supply wire to the (+) terminal and
the negative supply wire to the (-) terminal.
6. Replace cover to the wiring compartment of transmitter.

2.6 Configuring the Transmitter
The Radar transmitter comes factory-calibrated and can be
configured in minutes for specific applications.
Before configuring the transmitter, collect the operating
parameters information. Then, power-up the transmitter
on the bench and follow through the step-by-step proce-
dures for the menu-driven transmitter display. Information
on configuring the transmitter using a HART communica-
tor is given in Configuration Using HART (Section 2.7).
2.6.1 Operating Parameters
Some key information is needed to configure the Radar
transmitter. If necessary, complete the configuration infor-
mation table in Section 1.1.2.
2.6.2 Setting Up for Shop Configuration
The Radar transmitter can be configured at a test bench by
connecting a 24 VDC power supply directly to the trans-
mitter terminals. The connections are illustrated in the
accompanying diagrams. An optional digital multimeter is
shown if current measurements are desired.
When using a HART communicator for configuration, a
minimum 250 Ωline load resistance is required. See the
HART communicator manual for more information.
2.6.3 Transmitter Display and Keypad
The R82 transmitter has a local user interface consisting of
a 2-line by 16-character liquid-crystal display (LCD) and
4-push-button keypad. All transmitter measurement data
and configuration information is shown in the LCD.
The transmitter default display is the measurement screen.
It cycles every 5 seconds to display *STATUS*, *LEVEL*,
*ECHO STRENGTH*, *%OUTPUT*, *LOOP CUR-
RENT* and *LOCAL TAG* information. The transmit-
ter defaults to this display after 5 minutes if no keystrokes
are sensed. You can also access each of these screens indi-
vidually. The display will not return to the default screen
if left in one of these screens. For example, the device can
be left to read only LEVEL indefinitely if left in this
screen.

2.6.5 Password Protection (Default = 0)
The Radar transmitter is password protected to restrict
access to certain portions of the menu structure that affect
the operation of the system. When the proper password is
entered, an exclamation point (!) appears as the last charac-
ter of the first line of the display. The password can be
changed to any numerical value up to 255. The password
is required whenever configuration values are changed.
The default password installed in the transmitter at the fac-
tory is 0 (password disabled). The last step in the configura-
tion menu provides the option to enter a new password. If
0 is entered as a password, the transmitter is no longer pass-
word protected and any value in the menu can be altered
(except diagnostic values) without entering a confirming
password.
NOTE: If the password is not known, the menu item New Password
(Section 2.6.6.1, item #39) displays an encrypted value repre-
senting the present password. Call the factory with this
encrypted value to determine the actual password.

3.1 Description
The Model R82 is a two-wire, 24 VDC level transmitter
based on the concept of pulse burst radar operating at
26GHz. The electronics are mounted in a metal or plastic
housing with an innovative, internal launcher orientation
mechanism.
3.2 Theory of Operation
3.2.1 Pulse Burst Radar
The Model R82 is a top-mounted, downward-looking pulse
burst radar operating at 26 GHz. Unlike true pulse devices
that transmit a single, sharp (fast rise-time) waveform of
wide-band energy, the R82 emits short bursts of 5.8 or
26GHz energy and measures the transit time of the signal
reflected off the liquid surface. Distance is calculated utiliz-
ing the equation Distance = C ×Transit time/2, then devel-
oping the Level value by factoring in Tank Height and
Sensor Offset information. The exact reference point for
distance and level calculations is the Sensor Reference
Point—bottom of an NPT thread, top of a BSP thread or
face of a flange.

The exact level measurement is extracted from false echo
reflections and other background noise via the use of sophis-
ticated signal processing. The new R82 circuitry is extreme-
ly energy efficient so no duty cycling is necessary to accom-
plish effective measurement. For this reason, the R82 can
track high rates of change that were heretofore impossible
with existing loop-powered radar transmitters.
3.2.2 Equivalent Time Sampling
ETS, or Equivalent Time Sampling, is used to measure the
high speed, low power EM (electromagnetic) energy. ETS is
a critical key in the application of Radar to vessel level
measurement technology. The high speed electromagnetic
energy (1000 ft/µs) is difficult to measure over short dis-
tances and at the resolution required in the process industry.
ETS captures the EM signals in real time (nanoseconds) and
reconstructs them in equivalent time (milliseconds), which
is much easier to measure with today’s technology.
ETS is accomplished by scanning the tank to collect thou-
sands of samples. The round-trip event on a 40-foot (12.3m)
tank takes only 82 nanoseconds in real time. After it is
reconstructed in equivalent time it measures 123 milliseconds.

3.3 Troubleshooting
The Model R82 transmitter is designed and engineered for
trouble-free operation over a wide range of operating
conditions. Common transmitter problems are discussed
in terms of their symptoms and recommended corrective
actions.
WARNING! Explosion hazard. Do not remove covers unless power
has been switched off or the area is known to be non-
hazardous.
Use of the included PACTware™PC program is highly
recommended and invaluable for troubleshooting and
advanced calibration. A HART RS232 or USB modem
(purchased separately) is required. See Magnetrol
PACTware™bulletin 59-101.
Symptom Problem Solution
Level reading drops out at a
repeatable position in the
vessel
Multipath is cancelling good
level signal
Orient launcher to reduce multipath; turn launcher 10–20 degrees (1–2 index
marks) at a time until multipath at this point disappears. Refer to Section 2.4.2.3
Level reading locked onto a
value that is not correct
Level
Measurement engine finding
a reflection it believes is
level signal
1. Is high dielectric (ε>10) foam present
2. Run False Target Rejection routine with Level below this point (or with Empty
tank) to eliminate false echoes
LEVEL, % Output and LOOP
values are all inaccurate
Basic configuration data
questionable
1. Check validity of all configuration data
2. Check DISTANCE value of device against manually measured distance
LEVEL readings are repeat-
able but consistently high (or
low) from actual by a fixed
amount
Configuration data does not
accurately match tank
dimensions
1. Ensure proper values for Tank Height and Sensor Offset
2. Check vessel for present liquid level. Trim Level can be used to ensure
exact measurement
3. Reconfigure LOOP values if necessary
LEVEL reading on Display is
correct but LOOP is stuck at
4 mA
HART Poll Address set a
value of 1-15
Set HART Poll Address to 0
LEVEL reading on Display
stuck at value related to
Blocking Distance
Device believes antenna is
flooded (level very near or
on antenna)
Check actual level. If antenna is not flooded, power down, then power up
transmitter with the level well below the antenna.

3.3.2 Error Messages
The Model R82 Radar transmitter utilizes a 3-section
hierarchy for reporting diagnostic conditions: FAULTS,
WARNINGS, and INFORMATION. This information
will be shown in the Home screen when the message is
active. A chronological listing of messages can be viewed
in the HISTORY screen.
FAULT: The highest level in the hierarchy of diagnostics
annunciating a defect or failure in circuitry or software that
precludes reliable measurement. The current (mA) value
unit defaults to 3.6, 22, or HOLD and the Home screen
will freeze showing the highest priority Fault. Other Faults
can also be viewed using the UP/DOWN arrows. A chrono-
logical listing of messages can be viewed in the HISTORY
screen.
WARNING (MESSAGE): The second level in the hierar-
chy of Diagnostics annunciating conditions that are not
fatal but may affect measurement. The highest priority
Warning will be placed on the main (rotating) screen when
a Warning is detected but will not affect output current.
Other Warnings can also be viewed using the UP/DOWN
arrows. A chronological listing of messages can be viewed
in the HISTORY screen.
INFORMATION (MESSAGE): The lowest level in the
hierarchy of diagnostic conditions providing operational
factors that are not critical to measurement. A chronological

Relative Dielectric (εr) A unitless number that indicates the
relative permittivity of a material.
Repeatability The maximum error between two or more output
readings of the same process condition.
RFI Radio Frequency Interference Electrical noise that can have
an adverse affect on electrical circuits, particularly low-power
devices.
Safety Zone A user-defined area just below the Blocking
Distance where level measurement still has a high degree of relia-
bility. Radar can develop ambiguous readings when the level
reaches the region of the antenna. An alarm can be annunciated
in this area for critical applications where reliable measurement is
a necessity for safety reasons.
Safety Zone Height The height of the region below the
Blocking Distance where an alarm will be annunciated upon
detection of liquid.
Safety Zone Fault An optional condition added, when necessary,
to ensure safe, reliable high-level readings in critical applications.
Choices are 3.6 mA, 22 mA, Latch 3.6 or Latch 22. If Latch 3.6
or Latch 22 are chosen, the loop current will remain in alarm
until it is cleared in SZ Latch menu screen.
Safety Zone Alarm Reset Use screen for clearing a Latched
Alarm set in Safety Zone Fault (above)
SnsrOfst Sensor Offset The distance (+ or -) between the
customer’s 100% reference point (tank top) and the Sensor
reference point (bottom of NPT thread, top of BSP thread
or face of flange).
Span The difference between the upper and lower limits of the
range.
Specific Gravity (SG) The ratio of the density of a material to
the density of water at the same conditions.
Sensitivity The amount of amplification applied to the Level
signal; a higher value aids in measuring low dielectric media; a
lower number assists in ignoring nearby objects.
Status The current state of the transmitter’s diagnostics; screen
updates every 10 seconds.
Targets Objects in the vessel that create reflections of the radar
signal (microwave energy).
Targ Rej Target Rejection The ability to ignore reflections from
objects in the vessel that are not the liquid level, i.e., false targets
(e.g. pipes, ladders, baffles).
Tank Ht Tank Height The tank measurement between the 0%
(tank bottom) and 100% (tank top).
Tank Top The 100% point in a vessel. Also considered for the
type of tank top; e.g. flat, dome, etc., which affects the develop-
ment of multiple echoes during high level conditions. Multiple
echoes can appear as an invalid Level signal.
TDR (Time Domain Reflectometry) Uses a waveguide to carry
EM energy to and from the surface of the media to measure dis-
tance; similar to conventional through-air Radar but much more
efficient. Also called Guided Wave Radar.
Trim 4/Trim 20 Built-in system capability to fine tune the
4 mA and 20 mA points so the transmitter output corresponds
exactly to user’s meter, DCS input, etc.
Trim Lvl Trim Level An offset parameter used to account for
various deviations in measurement. It is an offset value that can
force the transmitter to read the exact level reading.
Turbulnc Turbulence Agitation, or disturbance, of the liquid
level surface; greater the agitation, greater the scattering of the
radar signal (microwave energy).
Two Wire An electrical instrument design that uses one set of
wires to provide both the supply power and process measure-
ment signal. The process measurement is achieved by varying the
current of the loop. Also called Loop Powered.
Units The engineering units used to measure level in the
system. The choices are in (inches) and cm (centimeters).
Warning (message) The second level in the hierarchy of
Diagnostics annunciating conditions that are not fatal but may
affect measurement. A message will occur on the main (rotating)
screen when a Warning is detected but will not affect output cur-
rent. Further information can be obtained by viewing the Status
or Diagnostic screens.

Service Policy
Owners of Magnetrol/STI controls may request the return
of a control or any part of a control for complete rebuild-
ing or replacement. They will be rebuilt or replaced
promptly. Controls returned under our service policy
must be returned by Prepaid transportation.
Magnetrol/STI will repair or replace the control at no cost
to the purchaser (or owner) other than transportation if:
1. Returned within the warranty period; and
2. The factory inspection finds the cause of the claim to
be covered under the warranty.
If the trouble is the result of conditions beyond our con-
trol; or, is NOT covered by the warranty, there will be
charges for labor and the parts required to rebuild or
replace the equipment.
In some cases it may be expedient to ship replacement
parts; or, in extreme cases a complete new control, to
replace the original equipment before it is returned. If this
is desired, notify the factory of both the model and serial
numbers of the control to be replaced. In such cases, cred-
it for the materials returned will be determined on the
basis of the applicability of our warranty.
No claims for misapplication, labor, direct or consequen-
tial damage will be allowed.
Return Material Procedure
So that we may efficiently process any materials that are
returned, it is essential that a “Return Material
Authorization” (RMA) number be obtained from the fac-
tory, prior to the material's return. This is available
through Magnetrol/STI's local representative or by con-
tacting the factory. Please supply the following informa-
tion:
1. Company Name
2. Description of Material
3. Serial Number
4. Reason for Return
5. Application
Any unit that was used in a process must be properly
cleaned in accordance with OSHA standards, before it is
returned to the factory.
A Material Safety Data Sheet (MSDS) must accompany
material that was used in any media.
All shipments returned to the factory must be by prepaid
transportation.
All replacements will be shipped F.O.B. factory.
