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®L/S®compact pump are Masterflex®two-stop tube sets.

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 patient-connected applications, including,
but not limited to, medical and dental use and, accordingly, have not been submitted for FDA approval.

GENERAL DESCRIPTION

The MASTERFLEX®L/S®Compact
Pump System,

Figure 1,

is enclosed in

an epoxy-painted metal housing.
The Pump System can accommodate

one or two tubes simultaneously
(depending on model) at controlled
speeds as low as 20 rpm. Tubing is held
in place by stops bonded to the tubing
and slots in the Tubing Retainer
brackets. For a list of tube sets for 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 three rollers
for optimum flow and positive flow
checking. All units operate from an
External DC Power Supply and are
supplied with a Universal Power Supply
(see Input Specification for operating
voltage/frequency). This power supply
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 when
depressed.

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

SETUP

Use only MASTERFLEX®L/S®tubing sets to ensure
optimum performance. Use of other tubing may
void applicable warranties.

Selecting Tubing Size

Appendix A provides a list of tubing sets which will work
efficiently with the MASTERFLEX

®

L/S®Compact Pump
System. This list includes tubing diameters, flow rates in
mL/min and the maximum flow rates per revolution at 20 rpm
and 100 rpm. Tubing is listed by part number. For best
results, when using two tubes (two channel models only),
select tubes that provide flow rates within a 10:1 range.
(Tube diameter ratios should be within approximately 3.5:1.)
Silicone tubing should not be used with TYGON

®

or PHARMED®.

Installing Tubing in Pump Head

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. Push the Occlusion Bed Latch, Figure 4, to the right to

release the Occlusion Bed from the rotor.

3. Insert the tube set into the slot on one side of the tubing

retainer bracket with the tubing stop on top of the bracket
(opposite side from the rotor).

4. Wrap the tubing around the rollers and insert the tubing

into the slot on the opposite side of the bracket, stretching
the tubing slightly so that the second tubing stop is also on
top of the bracket.

5. For two channel modes, the tubing must be in the same

slots on both sides of the bracket (i.e. both in front slot or
both in rear slot). If two tubes are being installed, repeat 3
and 4 above with the second tube set.

6. Lift the occlusion bed up against the tubing and push the

occlusion bed latch to the left until it locks in place in the
cutout on the occlusion bed.

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.

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

Connecting Primary Power

Terminals 1 and 2 on the rear panel Barrier Terminal Strip,
Figure 3, provide a means for connecting a remote DC power
source. The positive (+) terminal is terminal 1. The negative (–)
terminal is terminal 2.

NOTE: 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 life is
decreased with increased operating speed.

Priming Pump System

The MAX Push Button is used for priming and purging the
Pump System. When the MAX button is depressed, the pump
operates at maximum speed in the selected direction until the
button is released.

MAINTENANCE

Cleaning: Keep the drive enclosure clean with mild
detergents. Never immerse nor use excessive fluid.

Motor/Brush Replacement: The motor used in this
inexpensive drive is not serviceable or repairable and has
brushes which cannot be replaced. The motor is rated for a
continuous duty life of 1500 operating hours minimum.
Operation at other than continuous duty cycles will result in
longer motor life. If motor failure for whatever reason occurs,
the motor must be replaced.
