OCCLUSION ADJUSTMENT
(on 77201-60, -62 models only)
Adjust occlusion setting near top of pump head. (Figure #5.)
“4” for nominal performance;
“5” for increased pressure/vacuum
with reduced tubing life;
“2” or “3” for longer life with less
pressure and vacuum.
NOTE: For optimum performance,
turn knob to “1” after loading. Start
drive and adjust knob until pump primes
and fluid begins to flow.
NOTE: Occlusion usually does not need
to be readjusted when changing tubing.
MULTI-CHANNEL MOUNTING
L/S EASY-LOAD II Pump Heads can be mounted in tandem (up to four), depending
on the torque capabilities of the drive. (See Figure #6.)
Special mounting hardware is required.
See REPLACEMENT PARTS AND ACCESSORIES for mounting hardware.
Figure #6. Multi-channel Mounting
CAUTION: DO NOT OVER-TIGHTEN SCREWS ORWING NUTS.
NOTE: The L/S EASY-LOAD II Pump Head can be used in any combination with
other L/S EASY-LOAD Pump Heads. The longer L/S EASY-LOAD II mounting
hardware is required (not supplied).
NOTE: The tubing on the inside L/S EASY-LOAD II Pump Head(s) can be changed.

INTRODUCTION AND GENERAL DESCRIPTION
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
