The maximum water depth is 35 millimetres below the tank rim. This level is just beneath the cradle
wheels support rail and you should use this rail as a guide.
The minimum filling level is 30 millimetres above the bottom of the oscillating cradle, or approximately 50
millimetres from the bottom of the water tank.
If the water level falls below this minimum level during operation, the water bath should be powered off,
disconnected from the mains electrical supply and the water level topped up with cold water. Be aware
that this will result in the rapid decrease in the water bath water temperature and the effect of this in
relation to the current procedure being carried out must be considered.
No liability will be accepted if in the normal course of operation the contents of the containers being
heated and oscillated are damaged due to insufficient water levels or inappropriate temperatures being
applied as a result of re-filling.

CAUTION
CAUTIONCAUTION
CAUTION
When working with glass tubes, flasks, bottles, breakable or other brittle or fragile articles it is important
to use an appropriate retaining rack or fixture that ensures individual vessels are supported
independently and cannot come into contact with one another.
For example, if using glass test tubes, each tube should be retained in it’s own division of a test tube
rack, and the rack itself should be wide enough to be retained by the base of the oscillating cradle
without sliding around during oscillation. A powder coated stainless steel test tube rack is
recommended for retaining test tubes.
No vessel should be allowed to come into contact with any other vessel during high speed oscillation in
order to prevent breakage and a potentially hazardous situation from being created.
ALWAYS use appropriate tools (such as silicon insulated tongs) to load and unload items from the
water to avoid your hands coming into contact with sharp, broken or contaminated vessels.
- Turn power Off to the oscillating cradle by setting the Oscillation On/Off mains power switch (element
6 in Figure 1) up to the setting marked with a circle.
-When loading, use appropriate tools (such as silicon insulated tongs) to place the required rack,
container or accessory onto the oscillating platform. Ensure the item is adequately retained by the 2
retaining walls on the bottom of the cradle. If the item is too small to be adequately retained, it should
be loaded into another suitable rack or tray which will be adequately retained by the retaining walls.
-When unloading, use appropriate tools (such as silicon insulated tongs) to slowly remove the items
and place them onto a water-proof and heat-proof surface.
-Continue to load or unload your containers, racks or accessories until complete.

NE ER touch the water tank or heating element whilst conducting the Over-Temperature Safety Cutout
Test as serious burns and scalding could result.
The test involves water reaching boiling temperature and the resulting steam present could cause serious
burns or scalding.
ALWAYS wear eye protection during the Over-Temperature Safety Cutout Test.
ALWAYS maintain a safe working distance from the water bath during the Over-Temperature Safety
Cutout Test.
-Connect power to the water bath as per the section of this User Manual labeled “Connecting Power”.
-Switch on the heating system as per the section of this User Manual labeled “Switching On The Water
Heating”. There is no need to switch on the oscillating cradle for the test.
-Ensure the temperature set-point is set higher than the temperature of the water used to fill the tank,
this ensures the heating element will remain on during the test. Refer to the section of this User Manual
labeled “Setting the Required Water Temperature”.
-The water bath will begin heating the water and the Heating Element Indicator (element 7 in Figure 1)
will light up.
-Prepare 600mL of cold water ready to fill the water tank on completion of the test.

-After a period of less than 60 seconds following the surface of the heating element being completely
dry, the over-temperature cutout should activate. When the cutout activates, a small click sound may be
heard and the Heating Element Indicator (element 7 in Figure 1) light will go out. If the over-temperature
cutout has failed to operate within 60 seconds of the heating element being completely dry, the test has
failed and the water bath should be turned off immediately to prevent damage to the water bath.
-Depending on the quality of the water being used, an unpleasant smell may also be noticed as a result
of the impurities in the water becoming hot. This is normal.
-Once the test has been completed (either the cutout activated or 60 seconds has passed following the
element being completely dry and the cutout has not activated), turn off all power to the water bath
immediately by setting both mains power switches (elements 6 and 8 in Figure 1) to the up position
marked with a circle and refill the water tank with 600mL of cold water to cool the element by referring
to the section in this User Manual labeled “Filling The Water Tank”. This will help to maintain the
working life of the over-temperature safety device.
-If the over-temperature cutout has failed to operate, contact Ratek using the contact details provided in
the section of this User Manual titled “Ratek Service Contact Information”.
