come in contact with any metal components on your lab bench.
2.3. Installation
Using desired tray, place the tray into the bath, the tray is self
positioning and only needs to be located into the approximate
center of the tank.
The bath is capable of providing an orbital shake or a reciprocating
shake by simple reversing the tray. If an orbital shake is desired,
place the tray into the bath so that the word “Orbital” (which is
stamp onto the tray) is position towards the font of the bath. If a
reciprocating shake is desired, align the tray with the word
“Orbital” towards the rear.
Be certain that the drain hose assembly is removed from the drain
port prior to filling with the tank.
Use water only, fill bath to a minimum of 2” above the base of the
tank and the maximum of 3“ from the top of the tank when the
bath is fully loaded. A lid must be used with the bath at
temperatures above 60°C. After bath is filled with water, connect
the power line cord to the unit.
The power switch is located on the front panel and is used to turn
the unit on and off.

4.1 Universal Tray (290410)
The Universal Tray accommodates a wide variety of different vessels. The
configuration of the springs can be changed to accommodate the number of each
size of Erlenmeyer flask as follows:
The Universal Tray is designed so that springs may be added, moved, or removed
to accommodate different shaped vessels. The tray has a series of holes
positioned along both the long side and short sides. These holes can be used to
attach the springs to fit specific sized vessels.
NOTE: The bottom of the Universal Flask Tray is comprised of magnets.
Take care to ensure magnets do not come in contact with any metal
components on your lab bench.
4.2 Tray for Test Tube Racks (290420)
The Test Tube Tray will accommodate up to 5 Test Tube Racks. The Test Tube
Racks are available in 6 different test tube sizes. The chart below describes the
each Test Tube Rack item number, the size and quantity of test tubes that it can
hold.

4. Accessories (cont’d)
4.3 Perforated Tray (290430)
The perforated tray is used to convert the bath to an ordinary unstirred water bath.
To install, remove the tray that is presently installed in the tank. Place the
Perforated Tray directly on the bottom of the tank, positioned over the roller ball
bearings.
4.4 Gabled Lid, Stainless Steel (290320)
4.5 Bath Algaecide (B1906001)
5. Maintenance and Service
The adjustable high temperature alarm cutout should be tested periodically by
setting the high temperature alarm value below the set temperature value, when
this condition is present the unit should go into high temperature alarm failure as
indicated in step 3.4.6
The unit is equipped with circuit breaker(s) on the rear of the unit. The breakers
are reset by depressing fully.
To ensure optimal performance of the shaking mechanism, the tray, and bottom of
the tank including the transfer ball assembly should be cleaned periodically to
remove any scale build up. The tray and the bottom of the tank can be cleaned
with warm soapy water. If desired, the transfer ball assembly can be removed and
cleaned with warm soapy water as well. To remove the transfer ball assembly,
remove the 3 nuts holding it in place. Be certain not to remove any of the 4
transfer balls, the positioning of these balls is critical to the operating of the
unit, and their location has been factory calibrated.
If bath is going to unused for more than a couple of days, it is recommended to
drain the water from the tank. This will prevent the any possibility of corrosion
which can occur with distilled or deionized water and even some tap water, even
with the high grade of stainless steel used in the manufacture of this unit.
When the bath is used under certain conditions, algal growth can occur which can
be mistaken for rust. This can easily be cleaned off using warm soapy water.
Boekel recommends the use of a bath algaecide, item # B1906001 to help maintain
the bath water. Apply treatment at a dose of 20 drops per 1 gallon of distilled
water, free of visible algae.
