WARNING: Tubing breakage may result in fluid being sprayed from pump. Use appropriate measures

to protect operator and equipment.

CAUTIONS: Tubing for use with the MASTERFLEX C/L Pump Systems is Microbore Autoanalysis Tubing. See

Appendix A for specifics. Use of tubing other than that specified will result in poor pumping perfor­mance and/or pump system damage and voiding of applicable warranty.

Do not close the occlusion bed by pulling up on the locking tabs. Damage to the tabs may occur.

The MASTERFLEX C/L Pump System is designed to pump
fluid through Microbore tubing by means of peristaltic action
at very low flow rates. It is ideal for sanitizers, reagent dis-

pensing, analyzers, printing systems, controlled feeding and
non-human infusion procedures.

GGEENNEERRAALL DDEESSCCRRIIPPTTIIOONN

The MASTERFLEX C/L Pump System,
Figure 1, is enclosed in a plastic 1/4 DIN
Case.

Rubber Feet, supplied with the unit, can be
attached to the bottom of the Case for oper­ating on a bench or other flat surface and for
stability when stacking multiple units. The
enclosure allows panel mounting using
optional Mounting Brackets (see Accessory
Section for Part No. and page 6 for mount­ing instructions).

The Pump System accommodates one tube
at controlled speeds as low as 1.7 rpm.
Tubing is held in place by spring-loaded
Tubing Retainers. For a list of tubing sizes
for use with the Pump System, refer to
Appendix A.

The latching Occlusion Bed allows quick

Head Rotor contains four rollers for
minimum pulsation. All units operate from
an External DC Power Supply. The AC mod­els are supplied with a Universal Power
Supply, which provides a DC output for
connection to the Pump Drive.

The single-turn, adjustable Speed
Control, Figure 2, provides variable flow -
operation. The green PWR On indicator
lights whenever the pump is operating. The
Power On/Direction Switch turns power on
when either clockwise or counterclockwise
pump rotor direction is selected. The MAX
Button is used for priming and purging and
operates the pump at maximum speed while
depressed.

Appendix A provides a list of tubing sizes which will work
efficiently with the MASTERFLEX C/L Pump System. This
list includes tubing diameters, flow rates in µL/min and the
maximum flow rates at 10 rpm, 80 rpm and 300 rpm. Tubing
is listed by part number.

WARNING: Be sure the Pump Drive is turned off

before proceeding. Loose clothing
could be caught in the rollers.

1. Place the Power On/Direction Switch, Figure 2, in the
center (Off) position.

2. Open the Door, Figure 2, by grasping the finger recesses
on either side and pulling away from the pump.

3. Release the Occlusion Bed, Figure 4, by squeezing the
Locking Tabs, Figure 4, together and sliding the bed down
towards the door hinge.

4. Insert the selected tubing into one of the Tubing Retainers,
Figure 4, by moving the retainer toward the center of the
pump and placing the tubing in the v-notch of the retainer.
Release the retainer so that the tubing is secured in place.

5. Wrap the tubing around the Rollers, Figure 4, and then
secure it in the other tubing retainer as in step 4. The tubing
should be stretched slightly around the rollers so that there
is no excess tubing between the rollers and the retainers.

6. Close the occlusion bed by pushing up on the recessed
area at the bottom, Figure 5, until the locking tabs snap into
place against the Bed Stops, Figure 5, on the housing.
Verify that there is no excess tubing between the rollers
and the retainers - any excess can be removed by pulling
slightly on the tubing outside of the pump.

CAUTION: Do not close the occlusion bed by

pulling up on the locking tabs. Damage
to the tabs may occur.

7. Close the door. The locking tabs must be on the outside of
the door and the door fully closed for proper operation.

The optional Mounting Brackets are used to attach the 1/4
DIN Case to a Mounting Rack. Use Mounting Brackets Part
No. 77120-03, (2/set).

1. Be sure the panel bezel is on the pump, then slide the
pump system through the front of the mounting rack.

2. Place a Mounting Bracket, Figure 6, between the grooved
bracket retainers on one side of the Case and slide the
Mounting Bracket back to lock into the retainer grooves.

3. Tighten the bracket screw against the back of the rack to
hold the Pump System in place.

4. Repeat steps 2 and 3 for the second Mounting Bracket
on the opposite side.

Four rubber feet are provided for operating the Pump System
on a bench or other flat surface and for stability when stack­ing multiple units. The feet should be installed at the four cor­ners on the bottom of the unit. Remove the
protective paper from the adhesive surface of each foot
and press the foot firmly on the bottom surface about
one-eighth inch in from and parallel to the outer edges.

Depending on the Pump System model, primary power may
be 100-240V AC or 12V DC. The DC models can be con­nected to any DC* supply and are not supplied with a
Universal Power Supply unit. Connect the External Power
Supply to the applicable input voltage source and
the output of the External Power Supply to the DC input
connector on the pump unit.

*Refer to Specifications for current supply voltage.

NOTE: The Power Supply output connection is center
positive (+).

Terminals 1 and 2 on the rear panel Barrier Terminal Strip,
Figure 3, provide a means for connecting a backup DC power
source. The positive (+) terminal is terminal 1. The negative
(–) terminal is terminal 2. Connection to these terminals would
usually be made only for emergency type operation in con­junction with an External Power Supply, or a stand-alone
operation for the DC models.

NOTE: Input voltage must not exceed 15V DC or equipment
may be damaged. A minimum of 11.0V DC is required for
proper operation.

Terminals 3 and 4 on the rear panel Terminal Strip, Figure 3,
are used for remote start/stop operation. Pump direction and
speed are not remotely controllable. In non-remote operation,
these terminals are connected together by a Shorting Bar.

For remote control by switch closure, remove the Shorting
Bar and connect the two terminals of the remote control
switch to terminals 3 and 4. A closure of the remote control
switch contacts will start the Pump System. Opening the
contact will stop the Pump System.

OOPPEERRAATTIIOONN

This section describes the procedures for obtaining desired
performance. Flow rate is determined by the drive speed and
the tubing size.

WARNING: Tubing breakage may result in fluid being

sprayed from pump. Use
appropriate measures to protect
operator and equipment.

The Pump System can be set to operate in either a clockwise
or a counterclockwise direction. The same control used to
select direction also turns power on or off. Select direction of
pump operation desired. PWR indicator should light.

SSeettttiinngg PPuummpp SSppeeeedd

Pump speed is controlled by the variable Speed Control.
Turning the control clockwise increases the speed. Tube life
is decreased with increased operating speed.

The MAX Push Button is used for priming and purging the
Pump System. When MAX is depressed, the pump operates
at maximum speed in the selected direction until the button is
released. Approximately two feet of tubing length can be
filled or emptied per minute using the MAX Push Button on
the 10 rpm units.
