WARNING: To reduce risk of electrical shock, connect only to a

properly grounded, grounding-type receptacle.

WARNINGS: Turn drive off before removing, adjusting or installing

tubing. Fingers or loose clothing could be caught
in the rollers.

(The rotor is partially exposed when the Actuator
lever is in the open position.)

Do not remove back cover. The strong spring inside
may cause injury.

Tubing breakage may result in fluid being sprayed
from pump. Use appropriate measures to protect
operator and equipment.

WARNING: Risk of crushing. Keep fingers away from rotor while

pump is in operation. Stop pump before loading or
unloading tubing.

Fingers may be trapped between rollers on the
pump rotor.

INTROD UC TION AND GENERAL DESCRIPTION

This L/S®EASY-LOAD®3 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 tub ing sizes for a wide range of flow rates. The
unique lever actuator design and automatic tubing retention allow quick tubing changes.
This pump is designed to transfer or dispense liquids of various viscosities, as well as solids
suspended in liquids. It is NOT intended to pump flammable or explosive substances.

A mounting kit adapts this pump to MASTERFLEX L/S drives. The kit includasterflexting plate
and four screws, which are used to attach the mounting plate to a drive. Pumps are easily
and quickly attached to the mounting plate, or another pump, by means of the bayonet feature
on the back of the pump. The pump may be mounted with tubing entering and exiting to the
left, right, up or down. Mounting orientation options may be limited with some drives. Pumps
are just as easily removed, using the one-finger release lever on the upper left side of the
pump. The tang on the pump shaft couples the pump to standard MASTERFLEX drives, for
power transmission.

Each pump is supplied complete with a 17-inch (43-cm) length of tubing, one mounting kit and
this manual. A Phillips screwdriver is required to complete installation.
