Installation
Model SHKE435HP and SHKE436HP onsole Orbital Shakers are
shipped with the following materials:
2 - Keys for the lid lock (packaged and attached to outside of unit)
1 - T-handle 5/32” hex wrench
2 - Platform alignment studs ¼-20
1 - Shaker platform
6 - Grade 8, 5/32” hex socket flat head screws (provided with platform)
2 - 3/4” Open end wrench
2 - ¼-20 x 7” Stand-off bolts with rubber caps
1 - Phillips screwdriver for flask clip installation and removal
1 - 8¾” Phillips screwdriver for flask clip installation and removal
1 - Line cord (country of destination)
To secure the console shaker to
the shipping pallet, hold-down
brackets are attached to slots in
both sides of the cabinet. The
brackets are fastened to the
wood pallet with lag screws
(Figure 1-2).
Install the shaker on a firm, level surface in an area free of dust and dirt.
To allow for lid opening, the back of the shaker must be at least 4 ½
inches from the wall. As the electrical plug is the “mains disconnect” for
the unit, the electrical wall outlet must remain accessible at all times.
To maintain the 4½ inch minimum distance between the rear of the unit
and the wall to allow for unobstructed lid opening, two ¼-20x7” bolts are
included in the parts bag.
Screw the bolts into the threaded holes on the back of the shaker cabinet
(Figure 1-3). The bolts
should be screwed in by
hand to the limit of the
threads. Further tightening
is unnecessary. Put the
protective rubber caps, also
supplied in the parts bag,
over the heads of the bolts.

A drain is provided in the bottom of the chamber for convenience when
cleaning or removing spills (Figure 1-4). A clear vinyl hose and plastic
valve is connected to the drain and accessed by removing the front grille
assembly and the lower front panel. The grille is removed by gently pulling
it off. It is held in place by six push-in type retainers.
To remove the cabinet panel located in back of the grille, remove the six
Phillips screws; three on the top and three on the bottom. It may also be
necessary to loosen the two left side Phillips screws which hold the foot
pedal assembly to the shaker frame.
A 1/4” stainless steel condensate drain
is located on the back of the shaker to
remove any water that may collect in
the air ductwork. Refer to Figure 1-5.
The lid of the console shaker is counterbalanced for ease of opening and
closing. A foot pedal on the lower right of the front of the cabinet is also
provided for operator convenience and ready access to the chamber.

Caution Remove the shipping bracket and install the shaker platform
before plugging in or attempting to operate the unit. s
After removing the orbital mechanism shipping bracket and installing the
platform, remove this protective decal from the control panel to begin
shaker operation.
Figure 1-7. Shipping Bracket
To protect the shaker’s orbital mechanism during shipment, a sheet metal
shipping bracket (Figure 1-7) is installed and must be removed before the
unit can be operated. Using a 7/16” and 9/16” hex wrench, remove the
three 1/4” and the single 3/8” screws. Retain this hardware for future
shipping.
This shaker accommodates either a 5/16” nominal heavy-duty, 29.5” wide
x 18” front-to-back platform.
All shaker platforms are attached to their orbital mechanisms with six 1/4-
20 hex socket flathead screws Grade 8. These screws are hardened and
should not be exchanged with any other screw type. The 5/32” hex socket
wrench, included with the shaker, must
be used when attaching the platform.
Refer to Figure 1-8.

7. Tighten all screws using the T-handle wrench.
Caution Use only the hex socket flat screws to fasten the platform, and
only the T-handle wrench to tighten the screws. Torque these screws to 10
ft-lbs. heck these screws monthly if the unit is operated at or near
maximum speed (525 RPM). s
Each Flask lip up to 6.0 liters in size comes with a metal spring that must
be installed onto the clip. For flask clips through 500 ml, insert the end of
each spring into the holes at the top of the clip leg (Figure 1-11).
The 2 liter, 2.8 liter, 4 liter, 5 liter, and 6 liter Flask lips use two sets of
metal springs and rubber spring tubes. On these larger clips, the springs are
installed by hooking their ends together as illustrated in Figure 1-12. 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.
Note that the rubber spring tubes are placed between the clip legs.

Model SHKE435HP and SHKE436HP shakers accommodate glassware in
numbers and sizes from ninety-one 25 ml flasks to four 6 liter flasks. All
platforms have mounting holes for flask clips and test tube racks made by
other manufacturers. Listed below are the dedicated platform kits available
for these shakers.
Table 1-1. Dedicated Platform Kits
Flask clips can be attached anywhere on the platform and flasks can be
inserted into any flask clip as the counter-balanced design of these shakers
compensates for unbalanced loads.
The flask clips are supplied with the proper screws and can be attached to
the platform with a standard Phillips screwdriver or the screwdriver
provided with the unit.
Figures 1-11 and 1-12 illustrate the installation of the flask clips. Note that
clips for 1, 2, 2.8, 4, 5, and 6 liter flasks use five screws. The 250/300ml
flask clip has an adhesive-backed flask cushion pad that is installed on the
flat base of the clip body. A hole is provided in the pad for the mounting
screw.

cable with RJ-11 plugs and an RJ-11 to DB-25 adapter are required. Refer
to Figure 1-18 for connector locations on the shaker back panel. Figure 1-
15 identifies the RS-232 and Remote Alarm pin contacts.
The data is “dumb terminal” formatted, which permits interfacing with
either a computer or a serial printer.

Model SHKE435HP and SHKE436HP shakers transmits= time, RPM
and temperature information one minute after power is first applied to the
unit, then every 60 minutes thereafter unless the shaker receives either a
< trl><Q> or a < trl><S>.
The shaker’s microprocessor responds to two commands from the remote:
<Ctrl><Q> (XON)
The shaker will immediately transmit time, speed, and temperature data
upon receiving a < TRL><Q> and will reset the 60 minute data
transmission interval timer.
<Ctrl><S> (XOFF)
The shaker will stop serial data transmission upon receiving a < trl><S>
until a < trl><Q> is received or power is cycled.
An internal SPDT relay is provided to monitor alarms and is connected by
a RJ-11 (telephone style) jack on the rear of the cabinet. The remote alarm
provides NO (normally open) and N (normally closed) output. Figure 1-
16 identifies the pin contacts and may be wired to a central remote alarm
location or to an independent alarm system. Figure 1-15 identifies the pin
contacts. Figure 1-18 shows the location of the Remote Alarm onnector.
A modular to modular cable (Stock No. 190388) and an RJ-11 telephone
style terminal converter (Stock No. 190392) or equivalent may be used to
convert the remote alarm output to a screw terminal connection. Refer to
Figures 1-16 and 1-17.
To protect the contents of
the shaker or prevent
tampering or unauthorized
access, a security lock is
located on the right side of
the lid (Figure 1-18). Two
keys for this lock are in the
parts package attached to the
outside of this unit when
shipped.

Section 2 Operation
Model SHKE435HP and SHKE436HP shakers are microprocessor-
controlled incubated orbital console shakers designed to accommodate a
wide variety of flasks, test tubes and other glassware. The control system is
easily programmed and stores the user-defined time, temperature and
speed settings in battery-supported memory that remain even when the
shaker is turned off and unplugged.
The platform speed controller continuously adjusts for line voltage
fluctuations and provides smooth transitions with consistent control. The
circuitry is designed to slowly bring the platform up to speed and down to
a stop to prevent liquid splashing from flasks or test tubes.
An insulated lid with viewing port is counter-balanced for easy opening by
hand or foot pedal. A safety interlock requires that the lid be closed for the
drive motor, circulating fans and heating elements to operate.
Caution It may take up to one minute to bring the platform up to full
speed. Never leave the shaker unattended when starting it.
Caution Make sure all flasks and test tube racks are firmly seated in the
clips and check the security of the flask clip and platform attachment
screws monthly.
Caution Do not operate the shaker at maximum speed without a load. s
