Avoid the intake of foreign bodies when using in vacuum mode.
1. Description
With their adjustable and precise dispensing pressure, the compressed air operated dispensing
systems KDS808/834A/824A provide a reliable flow control for low to high viscosity fluids
or soldering paste. An automatic timed pulse guarantees repeatable dispensed quantities,
while an adjustable vacuum feature prevents uncontrolled dripping by low viscosity media.
KDS808
A simple dispenser with an integral pressure regulator from 0 – 7 bar and pressure gauge.
Adjustable vacuum prevents dripping by the dispensed medium. The dispensed quantity is
controlled by the operator with a foot switch - there is no automatic timer control.
KDS834A
This is a microprocessor controlled dispenser with an integral pressure regulator from
0 – 7 bar and a pressure gauge. Adjustable vacuum prevents dripping by the dispensed
medium. Digital timer control for repeatable dispensed quantities. Dispensing pulses
adjustable from 0.01 to 99.99 sec. Timer pulse is initiated by a foot switch.
KDS824A
This is a microprocessor controlled dispenser with an integral pressure regulator from
0 – 7 bar and pressure gauges. Adjustable vacuum prevents dripping by the dispensed
medium. Digital timer control for repeatable dispensed quantities. Dispensing pulses
adjustable from 0.01 to 99.99 sec. Timer pulse is initiated by a foot switch.
It has an additional compressed air outlet for accessories, e.g. vacuum gripper.

2. Commissioning
Unpack the unit and check for any damage sustained while in transit. Notify the carrier of
any damage found.
KDS808
1. Fit the quick-release coupling for the compressed air hose OD 6mm to the rear of the
unit ( 7 ) (12 mm spanner).
2. Connect filtered compressed air supply max. 7 bar with air hose OD 6mm ( 7 ).
Important: Check the compressed air system for damage and ensure that the
compressed air hoses and couplings are seated properly. Protect the quick-release
coupling for the air supply against twisting.
3. Ensure that the unit is turned off.
4. Set the slide switch ( 9 ) to the correct mains supply voltage.
5. Connect the mains plug ( 10 ).
