9.3. Decontamination.
If the equipment has been exposed to spillage or contamination,
the responsible body is responsible for carrying out appropriate
decontamination. If hazardous material has been spilt on or inside
the equipment, decontamination should only be undertaken under the control
of the responsible body with due recognition of possible hazards. Before
using any cleaning or decontamination method, the responsible body should
check with the manufacturer that the proposed method will not damage the
equipment.
If the dry block cartridge comes into contact with liquids in cases of flask breakage or
light spillage, the procedure is:
1. Disconnect the Omni Reaction Station from the electrical supply.
2. The dry block should be removed from the control unit when cool to touch.
3. Remove any broken glass or solids from the dry block.
4. Place the dry block in a low temperature oven at 60-80°C in order to evaporate the
spilled fluid.
Only carry out oven drying procedure after ensuring that there is no low flash
point in the substance present with respect to 60–80°C drying temperature.
Replace the dry block back into the control unit of the Omni Reaction Station.
Prior to further use, the responsible body shall check the electrical safety of
the unit. Only if all safety requirements are met can the unit be used again.
The above procedure is intended as a guide. Should spillage occur with a toxic
or hazardous fluid then special precautions may be necessary.

This product should be serviced by a Bibby Scientific Service Engineer or by an agent
on behalf of Bibby Scientific l. If in doubt contact Bibby Scientific. See Section 10.
9.4. Calibration
9.4.1. Recalibration
•
Have a precision reference thermometer of calibrator to hand. Ensure that
OS1=0 and SIM=0
•
Switch the controller off and on again.
•
During the auto-test phase, press buttons button’s
+
and
keep them pressed until the controlled shows 0AD.
•
With buttons
and
selected 0AD or SAD;0AD allows a
calibration of 0, inserting a constant corrective over the while scale of
measurement. SAD allows a calibration of the top part of the measurement
scale with a proportional correction between the calibration point and 0
•
Press
o display the value and then use
+
or
to make the read value coincide with the value measured by the
reference instrument.
•
Exit from calibration by pressing button
.
9.5. Spillage and Decontamination.
In the event of spillage switch off and unplug this product from the mains electrical
supply. Wipe off all excess liquid from the unit and surrounding area using an

The coolant is piped through the plug via insulated standpipes terminated with quick-release
sealed connectors. Mating right-angled connectors are provided to allow the customer
’s
chilled coolant supply to be linked into the standpipe connectors
.
The customer
’s
chilled coolant supply must be below 3 bar pressure. Ensure
there is a free flow of coolant through the cooling plug
–
do not apply coolant flow until
the outlet pipe-work has been connected and unobstructed.
The Cooling Plug should only be inserted or removed from the dry block at coolant
temperatures
above 0
C
, to prevent icing problems.
The controller display will provide sub-zero temperature readings when the external probe
and cooling plug are used in tandem.
WARNING!
Do not leave a disconnected cooling plug in a dry block whilst heating.
Pressure may build up inside to cooling plug from previously used coolant and
cause a rupture of boiling fluid.
