Figure 1-11. Shaker on Base Unit
Figure 1-12. Stack on Stand

After positioning the shaker (or stack) in its
final location, it is critical that the unit(s) be as
level as possible. Each of the leveling feet on a
shaker or stand has an adjustment nut (the
lower one, for leveling purposes) and a locknut
(the upper one, for securing the adjustment).
See Figure 1-13.
Using a 3/4” or adjustable wrench, turn the adjustment nut (extend the
leveling foot) to achieve a level condition. Make sure the shaker (or stack)
is leveled side-to-side and front-to-back. This can usually be accomplished
by adjusting only two feet. Verify that all four feet are in full contact with
the floor when leveling is complete. To “tune out” any vibrations, see the
Tuning the Cabinet section. After each leveling (and/or tuning), secure the
adjustment in place by tightening the locknut against the base of the
cabinet/stand.
Caution The leveling feet extend only a very short distance. When the unit
is leveled and tuned, with the leveling feet locked in place, the adjustment
and locking nuts should be no further apart than 1/4 inch. s
Information concerning the two drains on these shakers follows.
A drain is provided in the bottom of the chamber for convenience when
cleaning or removing spills (Figure 1-14). A clear vinyl hose and plastic
valve are connected to the drain and accessed by removing the lower front
panel. The panel has two screws along the bottom and tabs along the top
located in slots.

Figure 1-14. Chamber Drain

A 3/8” O.D. stainless steel condensate drain is located on the right side of
the shaker in the side car (Model SHKE8000-7/SHKE8000-8CE only).
This drain removes any water which may collect in the air ductwork.
Water accumulates into a pan where it is evaporated by the heat from the
refrigeration system. This drain does not require maintenance.
Each flask clip up to 2.8 liters in size comes with a metal spring which
must be installed onto the clip. For flask clips through 500 ml, insert the
end of each spring into the holes on the top of the clip leg as shown in
Figure 1-15.
The 2.0 and 2.8 liter Flask Clips use two metal springs and rubber spring
tubes. On the larger clip, the springs are installed by hooking their ends
together as illustrated in Figure 1-16. The upper spring and spring tubes
should be installed prior to mounting the clip to the platform. The lower
spring and spring tubes however, are placed around the bottom of the clip
legs after the flask clip is fastened to the platform.
The 2 and 2.8 liter clips are supplied with two sets of springs and rubber
tubes.
Note that rubber spring tubes are placed between each clip leg.

The Model SHKE8000/SHKE8000-ICE and SHKE8000-7/SHKE8000-
8CE accommodate glassware in numbers and sizes from ninety-one 25ml
flasks to six 2.8 liter flasks. All platforms have mounting holes for flask
clips and test tube racks made by other manufacturers.
Listed below are the flask clip assemblies and kits available for these
shakers.
Flask clips can be attached anywhere on the shaker platform. The
counterbalanced design of these shakers can accommodate an unbalanced
load.
The flask clips are supplied with the proper screws and are attached to the
platform with a standard Phillips screwdriver or with the screwdriver
provided with the unit.
Figures 1-15 and 1-16 illustrate the installation of the flask clips. Note that
clips for 1, 2 and 2.8 liter flasks use five screws. The 250/300ml flask clip
has an adhesive-backed flask cushion pad which is installed on the flat base
of the clip body. A hole is provided in the pad for the mounting screw.

The Accessory Test Tube Racks and Test Tube Rack Holders are available
in four sizes and are listed in Table 1-2. All the Test Tube Rack Holders are
adjustable in seven positions, swinging and locking at 15°, 30° and 45° in
either direction. Figure 1-17 illustrates the Test Tube Rack Holder with the
rack in place.
To remove the rack, spread the metal tabs on either end of the holder and
lift it out.
To install the Test Tube Rack Holder onto the shaker platform, remove the
rack and rotate the swing-bed of the holder 90° by pulling the knobs of
the locking pins on either end of the holder outward. The pins are locked
in the outward position by turning the knobs 1/4-turn (Figure 1-18).
