Inserting Tubing
Section 3
Operation
WARNINGS: Tubing breakage may result in fluid being
sprayed from pump. Use appropriate measures to protect
operator and equipment.
Turn Pump System off before removing or installing tubing. Fingers or
loose clothing could be caught in the pump mechanism.
CAUTION: To avoid electrical shock, the power cord protec-
tive grounding conductor must be connected to ground. Not
for operation in wet locations as defined by EN61010-1.
If the product is not used in a manner specified in the
instructions, the protection provided by the equipment
may be impaired.
Tubing should be inspected periodically for tears, cracks, cut marks,
abrasions, inability to hold pressure, bubbles in the flow stream and
reduction or loss of flow.
Tubing life may be extended by periodically moving the worn tubing inside the
occlusion bed of the pump to the outside of the occlusion bed to the suction
side of the pump. This will avoid excessive tubing wear at any specific point.
Always move the worn tubing to the suction side of the pump.
CAUTION: When changing flow direction, allow the pump
to come to a complete stop before starting again. Failure to
do so could cause permanent damage to the motor.
1. Make sure the speed is set to the minimum setting.
2. Turn the power switch ON. Increase the speed to start the pump
action. The higher the rpm setting, the faster the speed of the pump.
3. The I/P Precision Variable-Speed Modular Drives are self-priming. To begin
pumping, select a flow direction with the flow direction button, insert the
intake and output tubing into a reservoir, and turn the unit ON. Prime the
tubing for at least 5 minutes. If accurate flow control is important, allow the
pump to prime for approximately 20 minutes for more stable flow
conditions.
NOTE:
When in INTernal mode, pump will start automatically after
brownout, powerout or if drive was turned off using the power switch
while pump was running.
