When your ROSS Mixer arrives, inspect the packaging/crating prior to accepting from the shipper for signs of
possible damage during transit. Inspect all packing slips and bills of lading to ensure that all listed parts
boxes or packages have been delivered with the shipment.
Since all shipments are normally shipped F.O.B. the ROSS factory, any damage or loss is the responsibility of
the carrier and should be reported to them immediately. If the terms of the sale are F.O.B. destination, and
there is damage, contact your ROSS representative or the factory immediately. Mail/fax a copy of the inspec-
tion report and the delivery receipt indicating the problem areas at the time of delivery to:
www.mixers.com
Carefully uncrate the machinery. Do not discard the shipping crate or any packing materials until the contents
of the crate/box have been carefully compared with the shipping documents. If any material is unsatisfactory
or missing, notify Charles Ross and Son Company at the above address and phone/fax numbers.
Rental machinery must be returned in its original and reusable packaging or crating to avoid additional
charges. Mark/tag the original crating and store in a secure area.
1. Crating.
All ROSS rental equipment is shipped in reusable crates or containers made up of heavy duty skids and slatted
crating. Smaller units are shipped in formed foam boxes. These crates/containers should be stored and used for the
return of the rented equipment. A "crate" charge will be assessed if the equipment is returned without the original
crating/container.
2. Cleaning.
All rental equipment is required to be returned completely cleaned and free of product. Since contamination is
always a possibility, an MSD sheet pertaining to the product(s) made on the equipment is required to accompany
the returned equipment.
To insure the safety of our personnel who will be cleaning and/or reconditioning the rented unit, the customer must
include the MSD sheet(s) of the material(s) that have been mixed in the rented unit. The MSD sheet(s) are to be
returned with the rented unit.
If the MSD sheet(s) is not returned with the rented unit the rental will continue until the MSD sheet(s) is received
by our plant.
4. Returning process.
When ready to return rented equipment to ROSS:
- Use the original crate/container.
- Secure all loose parts in boxes and secure all boxes to the skid.
- Include the operating and maintenance manual.
- Include all auxiliary equipment such as, inverters, heating/cooling units, controls ,etc.
- Include all MSDS sheets.
5. Freight.
All rental equipment is to be returned freight prepaid. The cost of freight on these units returned freight collect will
be billed to you with an additional $250.00 administrative charge.
2. All electrical installations should be performed by a licensed electrician and conform to the national, state
and local electrical codes.
3. Integrated and pre-wired control systems are standard with the DPM line of laboratory mixers. Noninte-
grated systems such as separate variable speed frequency inverter drives and/or operator controls are avail-
able as options. Mechanical variable speed drives are also available as an option. Standard control panels
are supplied rated as NEMA 12. Other Nema rated control systems are available such as Nema 1, 4, 4X, as
well as explosion proof Nema 7&9 or Nema 4 gas purged. Control system voltage must be specified at the
time of ordering, input voltage can be 115v 1/60Hz, 230v 3/60 Hz or 460v 3/60 Hz (380v, 575v, 50Hz).
4. Disconnects equipped with breakers or fuses should be installed between the power source and the equip-
ment control panel(s) or motor(s). Unless otherwise specified, the standard power requirements of the equip-
ment is 230v 3ph 60 Hz. Please refer to the wiring diagram and/or nameplate on the control system for
details. If there are any questions regarding proper electrical installation, contact the factory.
5. Install all required ground leads and/or grounding cables for static dissipation.
6. The standard integrated control panel comes completely wired for simple one point electrical power
hookup. Install the power leads to the terminals provided in the control panel as noted on the "electrical
wiring diagram" included in this manual. Polarity will not be a concern for the inverter drive system since the
"reverse" mode in the frequency inverter will be "locked-out" via the programmed settings. Note: If the
polarity is reversed, machines with motorized hydraulic pumps will "cavitate" and not raise when the
"raise and safety" buttons are depressed. Machines with mechanical variable speed drives will rotate
in reverse. In both these cases, two of the three power leads will need to be switched.
7. To avoid possible damage to the equipment or personal injury, the electrical installation and all electrical
systems must be checked and tested prior to starting the equipment.
a. With the disconnect in the "off" position and the E-stop button depressed, apply power to the system.
b. Check the line voltage on each leg.
c. If the line voltage is within +/-10% of the rated voltage, apply power to the controls by turning the
disconnect to the "ON" position and pulling out the emergency stop button.
d. All systems should have power at this time.
e. DO NOT START THE DRIVES OR MOTORS AT THIS TIME!
f. Check the operation of all limit switches, proximity sensors and other electrically operated safety
devices.
g. Check the rotation of the shaft by "jogging" the drive/motor. Correct shaft rotation will be clock-
wise. If the direction is reversed, Lockout all power to the controls and reverse the connection of any
two of the three main (hot) power leads. Check the direction again before start-up.
h. Check all systems, motors and drives for proper operation and rotation. 8

C. LUBRICATION.
1. Before starting the mixer, all oil/fluid levels for the hydraulic system, mechanical seals, bearings, planetary
gearbox and reducer must be checked for proper levels. NOTE: All required lubrication, including greasing
of bearings and lubricating fluids have been properly filled and maintained prior to shipping.
2. Reducer. The oil level in the reducer must be checked and properly filled along with the vent plug removed
and reinstalled correctly. The fill plug is located on the top of the reducer, the level plug is on the side and the
drain plug in on the bottom of the reducer. Follow the lubricating instructions on the nameplate of the reducer
or in the manufacturer’s literature provided in teh Appendix - Vendor Literature section of this manual. A
suitable oil is AGMA Lubricant 7EP or 8EP, ISO-ASTM viscosity grade 460-680. If the mixer is to
operate in an unusually high temperature room, over 90 degrees F, a synthetic or heavy duty oil must be used.
Do not mix synthetic and petroleum based oils.
3. Hydraulic Lift System. Check the fluid level in the hydraulic fluid reservoir by viewing the oil level
through the sight glass mounted on the side of the machine while the machine is in the fully down position. If
needed, fill the hydraulic fluid reservoir with any non-foaming hydraulic oil with an ISO-ASTM viscosity
grade 46 (ISO-46, AW-46) or equivilent. The fill plug is located on the top of the sheet metal enclosure and
the drain plug islocated under the base.
4. Planetary Gearbox. The planetary gearbox has been lubricated at the factory with the correct amount and
requested type of grease. Typically a high temperature synthetic grease is recommended although another
grease such as a Dupont Krytox (GPL-206) or Food Grade Grease can be used. Check the gearbox for proper
grease volume every 250 hours. Do not overfill the gearbox with grease! Overfilling will cause the grease to
be forced out between the shafts and seals or bushings. The gears in the planetary gearbox should have a good
coating of grease on them, the cavity in the gearbox should not be full.
5. The motor bearings are "sealed" and have been greased at the factory, no greasing should be required.
2. Attach the vacuum line to the FNPT fitting located on the side of the vacuum hood or at the back of the
mixer bonnet. Install shut-off and bleed valves on the vacuum line at this same fitting.
E. MIX CAN.
1. Before starting the mixing operation the mix can must be securely attached to the mixer using the locating
pins and lugs. This will ensure proper alignment with the stirrer blades and vacuum hood as well as closing
the limit switch connection.
2. The mix can is positioned and held in place by two locking pins and lugs located on the sides of the mix can
and the stainless steel riser bars mounted on the base of the mixer.
3. Mix cans' fitted with casters have been shimmed at the factory to raise and level the mix can to the vacuum
cover/hood and stirrer blades. Adjustment should not be required.

F. AIR/OIL HYDRAULIC LIFT SYSTEM (STANDARD).
1. The standard DPM laboratory mixer is equipped with an AIR/OIL HYDRAULIC lift system which is
shipped completely assembled and ready to operate. Check the fluid level in the hydraulic fluid reservoir by
viewing the oil level through the sight glass mounted on the side of the machine while the machine is in the
fully down position. If needed, fill the hydraulic fluid reservoir with any non-foaming hydraulic oil with an
ISO-ASTM viscosity grade 46 (ISO-46, AW-46) or equivilent. The fill plug is located on the top of the
sheet metal enclosure and the drain plug islocated under the base.
2. All hydraulic connections have been made at the factory and should be checked for leaks on initial start-up.
3. Any leaks detected will need to be sealed prior to applying pressure/power to the system. Leaks may cause
air to enter the system. If this occurs, you may experience a "chatter" in the movement of the lift. The system
will need to be bled free of air to eliminate the problem. The bleed point will be the highest point in the
system which should be at the top of the hydraulic cylinder.
4. Clean, dry, shop air rated at 80-100psig and 4-5scfm is required to operate the air/oil lift system.
5. Attach the appropriate shop air to the FNPT fitting located at the back end of the mixer base.
6. After installing the proper air supply and checking the hydraulic fluid level, check the system by switching
the "RAISE/LOWER" switch to the "RAISE" position and depressing both the green and red "SAFETY"
buttons. The machine should raise to its full height in 8-12 seconds.
2. All hydraulic connections have been made at the factory and should be checked for leaks on initial start-up.
3. Any leaks detected will need to be sealed prior to applying pressure/power to the system. Leaks may cause
air to enter the system. If this occurs, you may experience a "chatter" in the movement of the lift. The system
will need to be bled free of air to eliminate the problem. The bleed point will be the highest point in the
system which should be at the top of the hydraulic cylinder.
4. After installing the proper power supply and checking the hydraulic fluid level, check the system by switch-
ing the "RAISE/LOWER" switch to the "RAISE" position and depressing both the green and red "SAFETY"
buttons. The machine should raise to its full height in 8-12 seconds.

H. V-BELT SYSTEM.
1. The DPM laboratory double planetary mixer incorporates V-belt drives for power transmission. The drive
system includes a V-belt and a set of pulleys to help produce the desired speed and torque ranges.
2. The V-belt in this system will "stretch" during its life especially when it is new. The V-belt system requires
tension adjustment when first installed and as the belt wears or stretches.
3. A new V-belt drive should be checked frequently, after the first 15 minutes, every hour for the first 4 hours
of operation and periodically thereafter.
4. Remember to disconnect and lockout all power to the drive before removing guards or attempting any
maintenance.
5. Refer to the "Maintenance" section of this manual for specific details regarding proper V-belt tension.
I. THERMOCOUPLE (OPTIONAL).
The thermocouple is located in the side wall (flush type) of the mix can. The thermocouple is attached to the
temperature readout via the cord and plug assembly provided or it can be connected to any suitable hand-held
temperature meter using the proper thermocouple wire. The standard thermocouple used in these mixers is a
type "J". The indicator/readout and thermocouple wire must be matched with the type of thermocouple. Refer
to the indicator/readout product literature for detailed installation and programming information.
K. BENCH.
1. An optional bench is available to mount the machine on. This bench is sized to provide the correct height
and constructed to support the machine properly.
2. The bench and mixer base are joined by four bolts that install from below the mixer base.

OPERATION
DPM - LABORATORY DOUBLE PLANETARY MIXER
C. MIX CAN.
1. Before starting the mixing operation the mix can must be securely attached to the mixer base. The can is
positioned and held in place by two locking pins and locating lugs mounted on the side of the mix can and
riser bars. Appropriate grounding cables should also be attached to the mix can.
2. The machine will not operate without the mix can in place and the safety limit switch contacted.
2. Machines equipped with a frequency inverter as the control panel will utilize the "start" and "stop" buttons
located on the key pad of the inverter to start/stop the mixer unless the controls are explosion proof and the
inverter has been located in a remote location. In this case, "START' and "STOP" buttons along with a
"SPEED" potentiometer will be supplied..
H. DIGITAL READOUTS.
1. Many machines are equipped with operator control stations that may include digital readouts for mixer
speed, motor amps, vacuum and/or batch temperature for monitoring of the mixing process.
2. These readouts are preset at the factory and should require no programming or adjustment for use. If
adjustment or programming is required, refer to the specific product information located in the "Vendor
Product" section of this manual.
I. TEMPERATURE.
Temperature monitoring can be accomplished using a simple digital or analog readout (mounted in the control
panel or handheld) or with a temperature controller that can be programmed to turn on/off cooling/heating
fluids, sound alarms and shut down the mixer.
J. MIXING.
The art of "Mixology" is not always as simple as just putting all of the materials into the mixer and turning it
on. To achieve the best quality and consistency, proper selection of materials, formulation and equipment
must be matched with proper mixing technique. There are typically 3 stages to the "wet" mixing operation:
- Incorporation.
- Wetting.
- Breakdown of particle clusters (aggregates and agglomerates).
2. Turn on the appropriate mixing blade(s) and run at a speed sufficient to allow incorporation of the
next material.
3. If the next material is a powder, meter the powder into the fluid at a rate that will allow proper
"wetting" of the powders into the fluids. Dumping large lumps into the batch may cause damage to
mixing blades and will increase the mixing time.
K. VACUUM MIXING.
Mixing under vacuum is normally used to remove air from the batch but may also increase the evaporation of
other volatiles such as solvents or wetting agents. The reaction of each formula to vacuum is different and
should be closely monitored during trial runs. The horsepower requirements may change when mixing under a
vacuum along with the product viscosity. Air attached to "dry" particles or between wet surfaces will be
removed which will effect the rheological aspects of the batch.
1. Induction of dry powders while operating under vacuum is only recommended when introduced
from below the fluid level and into a "shear zone" to prevent dusting and quick wetting of the powders.
Normally this is done through a valve installed in the bottom of the mixing vessel (SISAL).
F. GEAR REDUCER.
1. After 50 hours of operation, the gear oil in the reducer housing should be drained and thoroughly flushed.
2. Refill with new oil to the proper level.
3. Change the gear oil every six (6) months or 2500 operating hours thereafter, more often in severe operating
conditions. Check the oil level more frequently if there is any sign of leakage. Refer to manufacturer’s
instruction sheet for additional information.
G. ELECTRIC MOTOR.
1. Most small motors are supplied with sealed-for-life bearings and require no lubrication.
2. Do not allow dust, dirt or other foreign materials to buildup on the outside of the motor. This will reduce
the heat exchange through the motor housing which will reduce the life of the motor.
3. Refer to the “Appendix - Vendor Product Information” section for additional information.

M. LUBRICANTS LIST.
Below is a specifications list of the lubricants used in this machine. Please note that specific brand names or
manufacturers are not mentioned. Your local grease/oil distributer will be able to provide a product based on
these specifications. Matching brand names is not important.
1. Reducer - Synthetic AGMA lubricant 7EP or 8EP, ISO-ASTM viscosity grade 460-680.
2. Bearings - Motor bearings are "sealed" and have been greased for life at the factory, no greasing should be
required although any high temperature synthetic bearing grease could be used.
3. Planetary Gearbox - high temperature synthetic grease is recommended although another grease such as
a Dupont Krytox (GPL-206) or a Food Grade Grease is also acceptable.
