Maintenance and cleaning
The equipment is maintenance-free. It is only sub-
ject to the natural wear and tear of components
and their statistical failure rate.
Cleaning
For cleaning disconnect
the main plug!
Use only cleaning agents which have been ap-
proved by IKA
® to clean the instrument.
Dirt Cleaning agent
Dye isopropyl alcohol
Construction material water containing tenside/
isopropyl alcohol
Cosmetics water containing tenside/
isopropyl alcohol
Foodstuff water containing tenside
Fuel water containing tenside
For materials which are not listed, please request
information from IKA
® .
Wear protective gloves during cleaning the instru-
ment.
Electrical devices may not be placed in the cleansing
agent for the purpose of cleaning.
Do not allow moisture to get into the equipment
when cleaning.
Before using another than the recommended
method for cleaning or decontamination, the user
must ascertain with IKA
® that this method does
not destroy the instrument.
When cleaning the unit, take particular care not
to bring substances containing oil or grease into
contact with the running surfaces of the cone pul-
ley and the friction wheel. This would substantially
reduce the frictional coefficient resulting from the
pairing of the friction wheel and cone pulley ma-
terials, and would impair power transmission in
the unit.
Spare parts order
When ordering spare parts, please give:
- machine type
- manufacturing number, see type plate
- item and designation of the spare part see
www.ika.com, spare parts diagram and spare
parts list
- software version.
Repair
Please send equipment for repair only after it
has been cleaned and is free from any materials
which may constitute a health hazard.
For repair, please request the “Decontamination
Certificate” form IKA ® or use the download
printout of it from IKA ® website: www.ika.com.
If you require servicing, return the equipment in its
original packaging. Storage packaging is not suffi-
cient. Please also use suitable transport packaging.
Check whether the voltage given on the type plate
corresponds to the available mains voltage.
The socket used must be
earthed (fitted with earth
contact).
If these conditions have been met, the machine is
ready to operate when the mains plug is plugged in.
If these conditions are not met, safe operation is not
guaranteed and the machine could be damaged.
During commissioning of the machine the output
shaft starts to run at the last speed set. Therefore
check the setting of the control knob (B). Also
ensure that the speed set is suitable for the test
medium selected.
Switching on the device
If in doubt, set the speed knob to the lowest
speed. In case of doubt use the rotary knob (B, see
Fig. 1) to set the lowest speed and set the drive at
the lowest speed position (back side, refer to the
attachment on side of overhead stirrer).
The unit starts to run when the rocker switch (A, see
Fig. 1) is switched to I position.
If the unit has not been used for some time, a knock-
ing noise will be heard when switching on, which is
due to the preload on the friction lining of the fric-
tion wheel drive. This has no detrimental effect on
the function of the unit, and the knocking noise will
disappear after a short running-in period.
