Installation
Remove your Platform Vari-Mix Rocker from the carton.
Inspect to ensure that the unit has not been damaged
during shipment. Set the rocker on a flat, stable surface
and plug into an appropriate outlet. Remove the white
silicone rubber top from the protective plastic packaging
and place the top on the metal platform.
Set the power toggle switch into the “ON” position. The
green power switch will illuminate to indicate that the unit
is “ON.” Set the pitch and the speed and the timer con-
trol knobs.
INTRODUCTION
Warning
Use a properly grounded electrical outlet
of correct voltage and current handling
capacity.

6
Place the timer control knob in the hold position for con-
stant operation. The platform should rock in a quiet,
smooth motion.
Setting the Speed
Set the speed control knob to the desired speed within the
5-30 rpm range. The speed control reference scale is laid
out in 1 rpm increments.
Setting the Pitch
oosen the knob securing the rocking arm to the drive
wheel. Slide the rocking arm in the groove on the drive
wheel to your desired rocking angle, as indicated on the
drive wheel. Tighten the knob finger tight to secure the
rocking arm.
Setting the Timer
Set the timer control knob to the time required, within the
time range provided (2 hrs for 60 Hz. models, 3 hrs. for 50
Hz. models). Carefully observe the timer reference scale.
The timer reference scale is laid out in 10 minute incre-
ments with 30 minute, 1 hour, 90 minute and 2 hour posi-
tions noted. The outer perimeter scale is referenced for
120/240 volt, 60 Hertz timer motor operation. The inner ref-
erence scale is for 120/240 volt, 50 Hertz timer motor oper-
ation. (It is necessary to provide a dual scale as this rotator
is sold worldwide.) The timer does not include an audible
alarm, so the rotator will simply stop operating when the
set time has elapsed.
Once the pitch, speed and time control knobs have been
set, the platform should rock in a quiet, smooth motion.
Operation
Not
If the equipment is used in a manner
not specified by the manufacturer,
the protection provided by the equip-
ment may be impared.

Operating Tips
1. It is safer to mix reagents and chemicals in
small mouth labware to avoid splashing.
Test vessel stability to ensure vessel will not
tip, teeter, walk or slide. Improvised tie downs
or trays may be used to hold unstable vessels
in position if you prefer.
2. The white silicone rubber top is removable. ift
one corner to remove top. The top must remain
clean to maintain its friction-gripping quality.
Wash with soap and water, dry and reinstall.
3. It is recommended that partial loads be
centered on top to evenly distribute weight for
longer life.
4. When the Platform Vari-Mix Rocker is sued
within an incubator, the incubator temperature
must be stabilized with the rocker on, as the
motor generates heat.
Your rocker requires minimal maintenance. The drive
motor is permanently lubricated.
OPERATION

8
Timer Verification
The timer settings may be verified by setting the indicator
line on the timer knob to a specified reference mark and
timing the elapsed time with a calibrated elapsed timer.
Adjusting the Calibration of the
Speed Control
1. With the speed control knob set at the 10 rpm
setting and the power switch off, plug the unit into
an outlet with the proper voltage.
2. Turn the power switch on and check the rocking
speed of the top with a tachometer. The rocking
speed should be 10 rpm ±1 rpm. If itʼs not, contin-
ue with step 3.
3. ocate the calibration potentiometer on the back
panel. Remove the cap. Insert a screwdriver and
turn the screwdriver clockwise to increase the
rpm and counterclockwise to decrease the rpm.
The maximum speed correction is 2-4 rpm. If
more adjustment is necessary, contact customer
service at 800-553-0039.
Your Platform Vari-Mix Rocker will operate within the speci-
fied operating range of 5-30 rpm under a no-load condition.
You may calibrate the rpm with a specific load using this
procedure. However, loads heavier or lighter than your spe-
cific load may cause an rpm variation.
Maintenance and Servicing
Not
If the equipment is used in a manner
not specified by the manufacturer, the
protection provided by the equipment
may be impaired.

Disassembling the Platform
Vari-Mix Rocker
1. Unplug unit.
2. Remove the nut securing the driver arm
to the rocking platform.
3. Slide the pivot bar out of its sleeve bearings.
Remove the rocking plate.
4. Remove the screws securing the top cover (2
per side and 2 on top). Remove the top cover.
5. All the components in the lower case are easily
accessible for replacement and removal.
However, some assembly tips are given as fol-
lows:
a. Remove the four Phillips head screws holding
the motor to the mounting plate to remove
motor.
b. Removing the timer control knob requires
resetting the red line indicator to the point
where the time elapses and tightening the set
screws. Check timing with a calibrated elapsed
timer.
6. Reassembly may be completed by reversing
the disassembly procedure.
