IXED SPEED INSTRUCTIONS
The Fixed Speed Vortexer runs at only 3200 rpms.
1. The vessel you are using must be pushed down to achieve motion. To get the desired mix, vary the angle of contact and pressure against the
mixing head.
2. The Fixed Speed Vortexer will return to standby when the tube is lifted off the cuphead.
3. Your Fixed Speed Vortexer can become warm to the touch with constant use. There is nothing wrong with it. At high performance settings the
motor (UL recognized component) simply puts out more heat.
Operating notes:
DO NOT use large accessories on this unit. This unit is designed for use with cuphead or 3" head only.
To Disconnect the Fixed Speed Vortexer from power mains, unplug the line cord.

NALOG INSTRUCTIONS
1. For intermittent operation, push switch to "Auto" position. For continuous operation, push switch to "On" position.
2. In either case, turn speed control to "1". In the "On" position, you will see the head in motion immediately. In the "Auto" position, the vessel
you are using must be pushed down to achieve motion. To get the desired mix, vary the speed of the motor and/or the angle of contact and pres-
sure against the mixing head.
3. When finished with either continuous or intermittent operation, return switch to "Off" position in the center.
4. The continuous "On" mode is for the larger accessories. In continuous "On" mode, DO NOT run above 900 rpm (analog speed setting of "5").
5. The intermittent "Auto" mode is intended for short mixing times of one minute or less at full speed. A rest period of 2 minutes is recommended
to minimize the possibility of overheating the motor. Your Vortex Mixer can become warm to the touch with constant use. There is nothing wrong
with it. At high performance settings the motor (UL recognized component) simply puts out more heat.
Operating notes:
IMPORTANT: When using larger accessories (insert retainer with foam inserts or ampule tube holders), DO NOT run analog above a 900 rpm, (analog
speed setting of "5"). UNIT DAMAGE WILL OCCUR.
