SETUP AND DRIVE OPERATION
1. Unpack the drive: save packaging material until proper
product operation has been verified.
2. Select and mount Pump Head and load tubing
(see Pump Head manual).
3. For 77200-20 plug in Universal Power supply and connect
to the back of the drive. (See Figure #3.)
4. For 77200-12 supply 11.0 to 15V DC to terminal strip
positions 1 and 2. (See Figure #3.)
5. The drive system can be set to operate in either a clock-
wise or a counterclockwise direction. The same control
used to select direction also turns power on or off. To
operate in a clockwise direction place direction control
switch in the "up" position. The POWER indicator should
light and the fluid will flow from right to left. To operate in
a counterclockwise direction, place direction switch in the
"down" position. The POWER indicator should light and
the fluid will flow from left to right. To turn pump off, place
switch in the "center" position.
6. The pump speed is controlled by the variable speed con-
trol. Turning the control clockwise increases the speed.
Tubing life is decreased with increased operating speed.
Speed can be controlled up to a 6:1 range.
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 3000 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.
Pump Heads Accepted: Only the MASTERFLEX
®
L/S
®
STANDARD, QUICK LOAD and EASY-LOAD are acceptable
for use with this pump drive. Only one Pump Head at a time
can be used with this drive unit.
CAUTIONS: Use of Pump Heads other than those
specified will result in unsatisfactory
performance, damage to the drive unit
and voiding of applicable warranties.
The drive system can only be used
with one Pump Head at a time. Use of
this drive unit with multiple Pump
Heads will result in unsatisfactory per-
formance, damage to the drive unit
and voiding of applicable warranties.
When mounting the Pump Head to the
drive unit, the mounting screws should
only be tightened fingertight. Excessive
tightening of the mounting screws will
result in binding and unsatisfactory
performance.
Tubing Accepted: The Pump Heads accepted for use with
drive can be used with MASTERFLEX precision tubing sizes

®
13, L/S
®
14 and L/S
®
16 in all formulations. For
L/S
®
17 and L/S
®
25 size tubing, use silicone or C-FLEX
