SETUP AND DRIVE
OPERATION
1. Unpack the drive: save packaging material until proper prod-
uct 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 clockwise
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 control.
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.
