Description; Installation/Setup - Cole-Parmer MICROPUMP 75211-10 Manual De Operación

DESCRIPTION

These electronic drives are self-contained compact units that include a drive motor and all operating controls (see
Figure 1). These drives are especially designed for magnetically coupled pumps.
The 75211-10, -15, -62 and -67 drives come without a pump head. They will accept all MICROPUMP Pump Heads with
standard mounting canisters. The Pump Heads can be easily mounted to the motor, which is accessible from the front
panel. High and low speed versions are available covering a wide range of flow rates. Contact your dealer for available
Pump Heads and performance information.
WARNING: Gear pumps should not be operated above 5000 rpm.
CAUTION: To prevent damage to pump, do not restrict pump inlet or run the pump dry.
The 75211-60 and -65 drives come with a 7-GPM Centrifugal Pump Head mounted on it. The Pump Head has 3/8 NPT(F)
inlet and 1/4 NPT(F) outlet ports.
The solid-state speed control circuitry offers excellent speed regulation even with line voltage and load variations. A
neon POWER indicator in the switch illuminates whenever the O/I switch is in the I (ON) position. Pump drive speed can
be manually controlled over a 100:1 range with the front panel mounted potentiometer. "Soft-start" and smooth gradual
acceleration to speed setting is provided when line power switching.

INSTALLATION/SETUP

Unpack the Pump Drive and retain all packing material until proper product operation has been verified.
The Pump Drive rests on four vibration isolator feet for placement on a bench, desk or table. It is supplied with a power
cord.
1. If applicable, attach the MICROPUMP Pump Head.
2. Check that the O/I Switch is in the O (OFF) position.
3. Connect the AC power cord on the rear panel to the AC power source.
4. Set the speed control to minimum.
5. Install the pump below the level of the supply liquid. The liquid must be under atmospheric conditions.
6. This completes the basic setup.
CAUTION: To prevent damage to pump, do not restrict pump inlet or run the pump dry.
