SAFETY PRECAUTIONS

Loading Tubing

WARNING: Turn off drive before removing or installing tubing.

Fingers or loose clothing could be caught in the rollers.

1. Rotate tubing retainer knob, Figure 2, counterclockwise to release retainer,
then pull to open cover.

2. Lift latch to open occlusion bed.

Figure 2. High-Performance Pump Head

INTRODUCTION

The MASTERFLEX®L/S®High-Performance Pump Head delivers in excess of
3 L/min flow at normal MASTERFLEX operating speeds and pressures. It is
designed for optimal pumping in the clockwise direction. There are two mounting
positions. Tubing entry and exit are either on the left side or on top of the pump
when mounted on a MASTERFLEX

®

L/S®Drive. The pump will operate with any

MASTERFLEX

®

L/S®drive with 180 oz-in (13 kg•cm) or more output torque.

SETUP AND OPERATION

Pump Drive Compatibility

The High-Performance Pump Head has a standard shaft interface to
accommodate MASTERFLEX

®

L/S®Pump Drives. Pump drive must provide
180 in-oz (13 kg•cm) torque. (NOTE: These drives are usually designated as
capable of driving two or more pump heads.)

Mounting Pump Head to Drive

1. Check that pump drive is turned OFF.

2. Align pump shaft tang with slot in motor shaft.

3. If pump drive has alignment pins, slide pump head alignment holes over

pins.

4. Secure pump to pump drive with the two mounting screws (furnished).

a. For left side tubing entry and exit, use round mounting holes.

(Labeled "A" in Figure 1.)

b. For top tubing entry and exit, use hexagonal mounting holes.

(Labeled "B" in Figure 1.)

Selecting Tubing

Pumps accept only L/S®15, L/S®24, L/S®35 and L/S®36 tubing. Use only
MASTERFLEX tubing that is surface-printed with the tubing designation.

3. Insert the MASTERFLEX tubing inside tubing guide and around rotor with the

ends of the tubing extending out of the tubing entrance and tubing exit as
shown in Figure 3. Center tubing on roller.

4. Press the occlusion bed against the tubing, and snap the latch closed.

5. Close the cover, then pull the tubing snug (do not stretch) around the rotor

assembly. Tighten the tubing retainer by rotating the tubing retainer knob
clockwise sufficiently to prevent the tube from moving. Pump is now ready
for operation.

Operation

1. Connect pump tubing to desired source and destination.
