This L/S EASY-LOAD II Pump Head, when combined with a MASTERFLEX® L/S®

drive or compatible system, is designed to provide a simple, easy-to-use peristaltic

pump system. The pump head accepts several different tubing sizes for a wide

range of flow rates. The unique over-center cam design and automatic tubing

retention allow quick tubing changes and greatly reduced maintenance time.

Each pump is supplied complete with a 15 in (38-cm) length of tubing, one

mounting hardware package and this manual. A flat-bladed screwdriver or Phillips

is required to complete installation.

DRIVE COMPATIBILITY AND SETUP

The L/S EASY-LOAD II Pump Head is compatible with most MASTERFLEX® L/S®

drives with a standard tang interface. Mount the pump head using the 2 screws

provided. (See Figure #1.)

TUBE LOADING

1. Be sure the pump drive is turned off.

2. Rotate the lever to the left to open the pump.

3. Load the correct size tubing. Center the tubing between the

retainers.(Figure #2.)

4. Rotate the lever to the right to close.(Figure #3.)

WARNING:

Stop the drive when changing the tubing or its

position in the rotor mechanism (the rotor is partially exposed when the LOADING LEVER is in the open position).

NOTE: For optimum tubing life, keep tubing straight where it enters and exits the pump.
