The IRIS vacuum mixer (R-080518) is used
to make investmets, plaster and similar
mixtures. The machine has been designed
as a simple and reliable tool for Dental Labs.
For optimum performance and a long
service life, please read the instructions for
use carefully.

INSTALLING THE UNIT

1. Carefully unpack your IRIS vacuum
mixer, and check for these fittings in the
packaging:
•
Power cable.
•
Spare filter.
•
550 cc. mixing bowl (D).
•
Kit to secure the mixer to the wall.
•
Plastic spatula for plaster-alginate (R-
060002).
2. Choose a wall well away from any
sources of heat, vibrations or moisture to
set up the mixer unit. It must also be
positioned on a firm, rigid, level surface.
3. Make two marks with a marker pen
exactly 80 mm. apart at the chosen
location. Ensure that the imaginary line
linking the two
horizontal. A level may be used if
required.
4. Drill out the holes marked by hand using
a 10 mm. widia bur.
5. Insert the nylon studs included in the
vacuum mixer kit in the drill holes. Then
screw in the cheese-head shed bolts,
allowing the heads to protrude around 4
mm.
6. Use the bolts to secure the IRIS vacuum
mixer firmly to the wall.
7. Use the pen to mark the position of the
fixing eye on the lower section of the
unit. Remove the mixer and drill out the
hole manually. Insert a nylon stud in the
orifice and put the unit back on.
8. Use a wrench to put the bolt through the
lower hole. Ensure the unit has been
firmly secured.
9. Hook up the mixer's power cable to 230
V, 50/60 Hz with earthing.

OPERATING THE MIXER

The mixer is now ready for use:
1. Use the main switch (E) to turn on the
machine.
2. Put the mixing ingredients into the bowl
(D). Pre-mix the products in the bowl
manually with a spatula.
3. Use gentle pressure to position the bowl
and the mixer connection (F) with a
good sealing, and then select the mixing
time in seconds by turning the timer
control (A) clockwise. The unit will then
start up.
4. Use the v acuum meter (B) to check the
vacuum in the bowl. If there is no
vacuum in the bowl, move it gently to
improve its seating. Keep hold of the
bowl until the meter needle reaches
yellow. You may now release the bowl.
5. During mixing operations, the needle
must remain in the green section. When
the pre-set time has elapsed, the unit
will stop.
6. Use the vacuum drain valve (C) to
remove the bowl from the unit. The mix
is now ready to be used.
A cycle may be cancelled during operation
by moving the timer control anticlockwise to
"0".
This machine has a "diaphragm" vacuum
pump. If the unit is started at very low room
temperature, the membrane rubber may not
be sufficiently elastic for best operation.
Thus we recommend that the mixer be run
for approximately 1 minute before starting
operations in cold environments.
