What is NOT Covered Under Warranty
•Flooding, as a result of failure to clean the drain or drain screen, that damages any
internal electrical or mechanical components of the machine will not be covered
under warranty.
•Failure to regulate and control the water pressure may cause failure of the water
solenoids or overflowing the limits of the drain in the machine (page 8). Damage
caused as a result will not be covered under warranty.
•Corrosion and oxidization as a result of negligent cleaning practices, which affect
the performance of the MultiPrep™ System and components, will not be covered
under warranty. This includes, but is not limited to, the micrometer heads, the
run-out of the platen base and/or platen, and the MultiPrep™ head vertical spindle.
•Damage from abuse, neglect, negligence, accidental breakage, improper use, or
failure to exercise reasonable care and maintenance in accordance with the
instructions accompanying this product will not be covered under warranty.

Installation
The unit should be placed on a clean, dry surface with the control panel facing the front of the
counter/table on which it will be placed.
Electrical
Before installing the plumbing, all electrical functions should be tested. See page 9 for a diagram
of the control panel and pages 10-11 for illustrations of the buttons and their respective functions.
Plug the power cord into the back of the machine (Figure 1), then into the wall socket (the
provided power cord is exclusively for use with the MultiPrep™ System). Turn the main power
switch on at the rear of the machine, above where the power cord is connected. Activate the
control panel by pressing the on/off button on the lower right of the panel. The LED in the
button’s upper left corner will illuminate, as will the LEDs in the timer and RPM display windows.
Using the keypad, enter an RPM value in the range between 5 and 350 (in 5 RPM increments) and
press ENTER, followed by the green RUN button. The platen will rotate in the direction selected.
The direction of the platen is selected using the buttons labeled with clockwise and
counterclockwise circular arrows. An illuminated LED on either button indicates which is activated.
Press the red STOP button and select rotation in the opposite direction. The LED of that button
will illuminate and an audible click will indicate that the relay has switched the motor direction.
Press the RUN button to ensure the platen rotates in the newly selected direction.
Press the COOLANT button and be sure the click of the solenoid is audible. This indicates that the
solenoid is activating properly.
Press the STOP button to turn the activated functions off.

Plumbing
Flow Rate: ½ gallons per minute (1.9 L/minute)
Minimum Inlet Water Pressure: 25 psi (1.76 kgf/cm²)
Maximum Inlet Water Pressure: 50 psi (3.52 kgf/cm²)
Drainage: 1 gal/minute (3.8 L/minute) (recommended @ 30 psi)
Inlet Tubing: ¼" OD (6.35 mm)
Drainage Tubing: 1¼" ID (32 mm)
Water Inlet
Install the supplied inlet water filter between the water source and the MultiPrep™ base.
The inlet fitting on the rear panel of the MultiPrep™ base (Figure 1) only requires the tube to be
inserted until it stops. No tools are required for this installation.
To remove the tubing, press the outer collar of the fitting in and pull the tubing out.
Note:Turn the water off at the source before removing the water tubing.
Drain
With the hose clamp on the drainage hose, position the hose onto the coupling at the rear service
panel (Figure 1). Tighten the hose clamp so the hose does not slip from the coupling. Use the 90
degree elbow fitting to direct the drain hose if the tubing does not bend sharply enough for proper
installation.
Activate the coolant solenoid by pressing the coolant button (water flow may need to be regulated
or adjusted using the valve).
Note: Do not use the valve at the water spout to completely shut off the water flow. It is rated
for 30 psi and is only intended to restrict the water flow during polishing.

MultiPrep™ Base Operation
Faceplate Diagram
Electronics Calibration
The MultiPrep™ System can operate at either 50 Hz or 60 Hz, and it is calibrated to 60 Hz prior to
shipping. If the unit is operated at 60 Hz frequency, no calibration is necessary. Machines
operating at 50 Hz require calibration following installation. Failure to recalibrate the unit
to 50 Hz will result in misrepresentation of the RPM and timer values.
To calibrate the electronics, turn the control panel on, then press 1, 0, 0, followed by ENTER.
Activate the platen by pressing the RUN button. After approximately 30 seconds, press 3, 5, 0,
then ENTER, and allow it to run for another 10 seconds. With the machine running at 350 RPM,
press and hold the ENTER button until two quick beeps followed by four additional beeps are
heard, then release the button. This will begin calibration by storing the accurate speeds into
memory.
The time of the calibration process will vary, but it will usually be complete after about 25 to 30
minutes. When the calibration cycle is complete, the control panel will power itself off. Turn the
main power off at the AC receptacle for at least five (5) seconds, and then back on for normal
operation. During the electronics calibration procedure, only the main power switch can stop the
machine.
Please contact Allied if there are any questions or concerns regarding this process.

Platens
The 8" aluminum platen included with the machine is precision lapped and hard anodized. The
lapping ensures flatness, and the anodizing hardens the aluminum, making it durable and resistant
to scratches and dings. On the underside a center hole is used to help locate the platen on center
with the platen base. The four smaller holes around the center hole are where the nylon drive-
pins engage the platen.
On the platen base, there is a stamped
letter “A” (Figure 2). This is used as a
reference, when placing platens on the
machine, to minimize run-out (page 19).
The platen included with the system has
an “A” stamped on the underside that
indicates where it should be aligned to
the platen base. Additional platens, not
originally purchased with the machine,
will not have this “A”, but they can still be
matched for minimal run-out (page 19).
Note: This is a precision polishing
machine; care must be taken to ensure its
performance. DO NOT DROP the
platen onto the platen base.
Repeated abuse will affect the
precision of the system. Keep the surfaces between the platen and the platen base clean and
dry, so the platen run-out remains within specifications. Excessive water and polishing suspension
buildup will adversely affect the run-out.
Splash Ring
Each machine comes with one (1) splash ring that is designed to collect and direct the water and
polishing liquids into the drain bowl. To maintain cleanliness, avoid contamination, and ensure
safety, it is strongly recommended the splash rings be used during operation. The splash ring
should also be cleaned as needed to prevent buildup of dirt and debris.
Control Panel, On/Off
This button activates and deactivates the control panel.
Platen Controls
The platen controls include buttons for: RPM, START/RUN, STOP/PAUSE, and clockwise and
counterclockwise platen rotation directions, which are illustrated above, respectively. Arrows mark
each platen direction button; an LED, when illuminated, indicates which direction is selected. If
during operation the button for the opposite direction is pressed, all functions are paused. The
new direction becomes active, but the machine will remain stopped until the platen is reactivated
by pressing the START/RUN button. The STOP/PAUSE button stops the platen, coolant, and any
activated MultiPrep™ head controls.
