Maintenance and cleaning
The equipment is maintenance-free. It is only subject to the
natural wear and tear of components and their statistical
failure rate.
Cleaning
For cleaning disconnect the mains plug!
Use only cleaning agents which have been approved by IKA
to clean IKA devices.
These are water (with tenside) and isopropanol.
Wear protective gloves during cleaning the devices.
Electrical devices may not be placed in the cleansing agent
for the purpose of cleaning.
Do not allow moisture to get into the device 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 device.
Maintenance
• Remove the top cover: by unscrewing the 4 screws on
bottom.
• Examine hoses visually for cracks. If cracks have developed
or the hose becomes brittle, replace with suitable new
ones.
• To clean the housing of the device, use only water with a
detergent that contains tensides, or use isopropylalcohol
for stubborn soiling.
Connect vacuum hose from inlet nozzle to recipient. Plug
in power socket to mains and flip rocker switch (
A , see Fig.
1 ) to “ I ” position to switch on the device.
Unscrew the 4 screws

Using the gas ballast valve
• Ensure that when the gas ballast valve is
open, the air/gas that enters through the
gas ballast valve doesn’t come in contact
with any hazardous, explosive or other-
wise dangerous mixtures that the vacuum
pump is pumping at its inlet.
• Venting the receptacles or the vacuum
pump using ambient air may under some
circumstances create a risk of serious dam-
age to the equipment and/or surrounding
installations and a risk to personnel of
serious injury or even death, due to the
formation of hazardous and/or explosive
mixtures if a reaction between the air and
the medium that is being pumped occurs
either within the pump or at its outlet.
For pumping condensable vapours (water vapour, solvents,
etc.):
• Let pump run with gas ballast valve closed until pump
reaches its operating temperature.
• Open gas ballast valve (refer to figure below).
Open
• Gas ballast valve is open when the notch on the cap is
aligned with the notch on the nozzle (Gas ballast valve
can be closed by rotating cap at least 90°).
• When gas ballast valve is opened, ultimate vacuum will be
reduced and pumping speed will decrease.
• Use inert gas at air inlet to avoid formation of explosive
mixtures.
Spare parts order
When ordering spare parts, please give:
• device type.
• serial number, see type plate.

Please only send devices in for repair that have been
cleaned and are free of materials which might pres-
ent health hazards.
For repair, please request the “ Safety Declaration ( De-
contamination Certificate )” from IKA or use the down-
load printout of it from IKA website at www.ika.com .
If your appliance requires repair, return it in its original pack-
aging. Storage packaging is not sufficient when sending the
