Remove rotor.
◊ Open protection lid and remove pump head hoses.
◊ Open flexible black lid located on the rotor centre.
◊ With a Phillips screwdriver to remove the central screw positioning.
◊ Pull the rotor hub off its axis.
◊ Between the hub and the shaft is a split collet. If the collet is retained by the shaft, pull it off, loosening, if necessary, using
light strokes. Do not try to remove it by prying with a screwdriver. If the collet is retained within the bucket, remove, if
necessary, slightly loosen the screw reinserting central locating and tapping the screw head.
Rotor replacement.
◊ Reassemble the split collet on the shaft, rotating it until it is fully inserted. Fit the body of the
rotor drive shaft as a unit.
◊ Open the flexible black cover of the centre rotor. With a Phillips screwdriver to tighten the
screw positioning a pair of 3 Nm to prevent the collet slipping during work. If the assembly
is correct, the guide rollers of the hose should be aligned with the outer surface of the track.
Close the flexible lid rotor.
◊ Close the cover and make sure the rotor is separated from it, watching the first rotation of the rotor.
Placing the tubes (hoses)
The 5000 pump heads are factory set to accommodate tubes from 1,6mm wall. Pumping performance may be adversely
affected if the tubes are not used right.
◊ Check hose length 225mm. to be placed inside the head. Please note,
if you put more than 225mm can be seen shortened tube life.
◊ Open the bottom clamp (spring) and put the hose to the first mark
of 225mm. aligned with the inside of the bracket that has the dock.
Loosen the clamp.
◊ Disengage the rotor clutch fully depressed the yellow button on the side of the rotor hub and rotor
turning the hub a few degrees, while maintaining the button. Now the rotor can give a complete
revolution independently of the gearbox and engine. If the clutch re-engages before the hose is
fully assembled, press the button again and turn the rotor a few degrees.

7
◊ Place the tubing around the track head, turning the rotor properly. Make sure the hose is not twisted or pinched between
the guide rollers and track. Check that the second mark of the 225mm. is located along the inner edge of the upper clamp.
◊ Open the upper hose clamp with spring and place the hose, making sure the hose does not twist and is supported
centrally between the guide rollers of the hose. Loosen the clamp
◊ Hose clamps, with spring, holding the hose must be strong enough to keep it from
Moving in or out of the pump head, but should not be tightened too much or choke the
passage of fluid. The clamps have a yellow slide that can be placed in two positions
while the clamps are open. The external position allows tightly hold the hose clamps,
while the inner position leaves him weaker. Adjust the sliders to prevent tube
movement during a test a few turns the rotor.
◊ Close the cover by pushing it fully until the latch engages
◊ Remember that it is appropriate, after 30 minutes of operation, tighten the hose back,
which can lengthen as it accommodates.
Tighten the hose so that the 225mm. hose are located between the parts of the hose
clamp that carry spring.
6- OPERATING
1. - Consult the table of dosages and install the appropriate tube (see maintenance section).
Remove the plastic cover of the pump head. Installing the tube with their terminals of fixation. When you settle the new
tube, should remain centred on the rollers to avoid the rotor to break the tube. Place the cover again. With each pump the
sizes of tube are giving. The feeding and discharge tubes could have any thickness of wall. But the tube that settles in the
pump head should have 1,6mm thickness of wall, except for pump head 1500-2r pump, 5000-2r and CF-3r with code pump
1.9747.24 which uses tube of 2,4mm wall thickness.
2. - Proceed to the programming of the cyclic timer. Seeing Description.
3. - Make sure that the voltage is 240V. Insert feeding and discharge tubes in the terminals of the pump head. Turn the - O -
reverse flow control button. Choose the speed acting on the digital speed control. Digital speed control can be set 0 - 99% in
1 % increments with 100 % repeat accuracy. Connect the cable plug. Push ON.
Because the friction of the tubes with the rollers increases with the tube diameter, the adjustable minimum speed increases
as much as big is the tube. Starting from the tube of 4,8mm the necessary minimum speed is the following one: tube 4,8mm
/ 5%, tube 6,4mm/10 %, tube 8mm/15 %.
It is not convenient to use smaller speed although the motor starts up since in any moment it can stop and to cause an
excessive heating of the regulation circuit that could be damaged if it remains in this situation for a lot of time.
When you use several CCF-3r pump head simultaneously in the pump 9745, tube diameter could be limited especially in
tubes of high hardness
7- REMOTE CONTROL
In the rear part of the pump there is a connection for a foot switch that is given as accessory with the order code 1.9740.02
When push the foot switch the dosage begins.
8- CHANGE TUBES
Press OF switch. Pump head 50: remove the three screws. To take out the tube together with their terminals of fixation. The
new tube should be centered on the rollers to avoid that the rotor breaks it. To take advantage of the turn of the slow rotor to
introduce the new tube. It is avoided this way to force the motor-axis when one tries to place the tube with the stopped rotor.
Take care
During the first minutes of operation some tubes, newly installed, undergo an elongation that alters the distances of
the tube and their fixings with the rollers. Readjust the tube in the pump head to prevent the rollers break the tube
unexpectedly.
Marking the tube with a marker makes it easier to detect a faulty attachment of the tube to their pump head which
will cause the tube to break through the rollers.
Place again the cover. Pump head CF, see “Description section”.
The supply and discharge tubes can have any thickness wall, but the tube that settles in the pump head should have a
thickness wall of 1,6mm. For pump with pump head 1500-2r and 5000-2r the wall thickness is 2,4mm. Also pump code
1.9745.24 with especial pump head CF-3r for 2,4mm thickness wall tube.
All the pumps are supplied with medical /alimentary degree silicone tube according to FDA norms and USP. It can sterilise.
Range of use until 250º C and half duration.

12-MAINTENANCE / SPARES
Before proceeding to any exam or repair it is necessary to disconnect of the mains. All initiative should be made by qualified
personnel to avoid bigger wrongs.
Trust their apparatus to a technical service authorized by DINKO Instruments.
The motor and block of the dispenser pump don’t require lubrication for what they don’t have maintenance. It is convenient
to lubricate the rollers lightly with silicone grease.
The tubes should be replaced periodically to avoid the break.
