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.

4.5 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.
