7) Install the baffle and baffle adapter.
• Unscrew nut and be careful not to lose the 2 ferrules underneath.
• Place the round end of the baffle in the bottom of the baffle adapter.
• Place the PTFE ferrule (white) flat end up down the shaft of the baffle.
• Place the Nylon ferrule (clear) with the flat end down, down the end of the baffle shaft.
• Place nut down the baffle shaft and screw loosely.
• Place baffle and adapter in a straight port on the reaction lid.
• Adjust to desired height in vessel and tighten nut.
(MAKE SURE BAFFLE DOES NOT TOUCH IMPELLER)
8) Mount the stirrer motor and stirrer rod coupling.
• Make sure the center of the locking handle on the top adjusting plate is facing toward the back
of the unit.
• The top motor adjusting plate on the stand should be as high as possible, make sure both knobs
are tight.
• Place stirrer rod in the hole and roughly adjust it to be lined up with the stirrer shaft. (There
should be about 3 to 4 inches between the stirrer shaft and glass stirrer rod).
9) Motor, coupling and stirrer rod assembly.
• Place the assembled stirrer coupling on the stir shaft and tighten the Allen screw.
• Carefully lower the top of the motor support down to the coupling and stop. Make sure that
everything is lined up!
• Lower the motor down so the shaft goes into the coupling about 3/4 of the way and tighten the
motor support bracket.
• Lift coupling with stirrer rod attached the rest of the way up. (This is to make sure the lower
impeller is not rubbing against the bottom of the reaction vessel.)
• Tighten the Chuck on the Stirrer motor.
