SAFETY PRECAUTIONS

WARNING: Tubing breakage may result in fluid being sprayed

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

CAUTION: 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.

WARNING: PRODUCT USE LIMITATION

These products are not designed for, nor intended for use in patient­connected applications; including, but not limited to , medical and dental
use, and accordingly have not been submitted for FDA approval.

These products are covered by one or more of the following U.S. and corresponding foreign patents:

INTRODUCTION

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 dispensing, analyz ers, printing systems, controlled
feeding and non-human infusion procedures.

GENERAL DESCRIPTION

The MASTERFLEX® C/L® Pump System, Figure 1, is enclosed in a plastic
1/4 DIN Case. The enclosure allows panel mounting using optional Mounting
Brackets (see Accessory Section). Rub ber Feet, supplied with the unit, can be
attached to the bottom of the Case for operating on a bench or other flat surf ace.
The Pump System can accommodate two tubes simultaneously for the 6 and
60 rpm systems at controlled speeds as low as 1 rpm. The 200 rpm system
accommodates one tube at controlled speeds as low as 35 rpm. Tubing is held
in place by spring-clip Tubing Retainers. For a list of tubing sizes f or use with the
Pump System, refer to Appendix A. The latching Occlusion Bed allows quick
loading or changing of tubing. The Pump Head Rotor contains six rollers for
minimum pulsation. All units operate from an Exter nal DC Power Supply. The
115V AC and 230V AC models are supplied with an External Power Supply,
which provides a DC output for connection to the Pump Drive.

Figure 1. MASTERFLEX® C/L® Pump System

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 cloc kwise 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.

The rear panel, Figure 3, contains a DC power input jack for connection of
primary power and a 4-terminal barrier str ip for connection of remote start/
stop and for a DC backup supply.

SETUP

Use only Microbore Autoanalysis tubing with MASTERFLEX® C/L® pumps

to ensure optimum performance.

Use of other tubing may void applicable warranties.

Selecting Tubing Size

Appendix A provides a list of tubing sizes which will work efficiently with the
MASTERFLEX
µL/min and the maximum flow rates at 6 rpm, 60 rpm and 200 rpm. T ubing is listed by
part number. For best results, when using two tubes, select tubes that provide flow
rates within a 10:1 range. (T ube diameter ratios should be within approximately 3.5:1.)
Silicone tubing should not be used with TYGON® or NORPRENE®.

Installing Tubing in Pump Head

®

C/L® Pump System. This list includes tubing diameters, flow r ates in

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. Press down on the Occlusion Bed Latch, Figure 4, to release the
Occlusion Bed from the rotor.

3. Gently stretch the tubing and insert the tubing into the spr ing-loaded left
rear Retainer.

4. While maintaining the slight amount of stretching, wrap the selected tubing
around the lower Rollers and secure the tubing in the right rear spring­loaded Retainer. If a second tubing is to be installed, secure the tubing in
the same manner using the front spring-loaded Retainers.

5. Lift up on the outer edge of the Occlusion Bed until it locks in position
holding the tubing against the bottom Rollers.

Installing Panel Mount Mounting Brackets

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 5, between the groo ved brack et 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.

Figure 5. Mounting Bracket Installation

Installing Rubber Feet

Four rubber feet are provided for operating the Pump System on a bench or
other flat surface. The feet should be installed at the four corners on the bottom
of the unit. Remo ve the protectiv e paper from the adhesive surf ace of each foot
and press the foot firmly on the bottom surface about one-eighth inch in from
and parallel to the outer edges.

7

Connecting Primary Power

Depending on the Pump System model, primary power may be 115V AC,
230V AC, 12V DC or 13.5V DC . The DC models can be connected to any DC*
supply and are not supplied with an External 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 (+).

Backup Battery Connection

Terminals 1 and 2 on the rear panel Barrier Terminal Strip, Figure 3, provide a
means for connecting a backup DC pow er source. The positive (+) terminal is
terminal 1. The negativ e (–) 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 f or the DC models.

NOTE

For Models 77120-30, -35, -40, -45, -52 and -62, input voltage
must not exceed 16V DC or equipment may be damaged. A
minimum of 11.5V DC is required for proper operation.

For Models 77120-20, -25 and -70, input voltage must not exceed
15V DC or equipment may be damaged. A minimum of 11.0V DC
is required for proper operation.

Remote Start/Stop Connection

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.

OPERATION

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.

Turning Pump System On and Selecting Direction of Operation

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.

Setting Pump Speed

Pump speed is controlled by the variable Speed Control. Turning the control
clockwise increases the speed. Tube lif e is decreased with increased oper ating
speed.

Priming Pump System

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 6 rpm units.

Cleaning

Clean exterior surfaces of case, control panel and pump rollers using dry or
damp cloth. Never immerse nor use excessive fluid.
