Operating and Safety Precautions

3.1 | SAFETY SYMBOL IDENTIFICATION

3.2 | EXPLANATION OF SAFETY SIGNAL WORDS

DANGER! Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING! Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION! Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or property damage.
NOTICE! Indicates information or a company policy that relates directly or indirectly to the safety of personnel or protection of property.
For safety purposes, this equipment should only be used by appropriately- trained personnel after they have read and understood this manual, and accounted for any and all potential hazards. If the pump is used in a manner not recommended by LMI Pump, the warranty may be voided and risk to equipment and personnel could occur.
The following precautions should be taken when working with LMI Pumps. Please read this section carefully prior to installation.
Protective Clothing: ALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or near your metering pump. Additional precautions should be taken depending on the solution being pumped. Refer to Safety Data Sheets (SDS) precautions from your solution supplier.
Liquid Compatibility: Determine if the materials of construction included in the liquid handling portion of your pump are adequate for the solution (chemical) to be pumped. Always refer to the solution supplier and the LMI Pump Chemical Resistance Chart for compatibility of your specific pump. Contact your local LMI Pump distributor for further information.
Electrical Connections:
WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into a properly grounded grounding-type receptacle with ratings conforming to the data on the pump control panel. The pump must be connected to a good ground. Do not use adapters! All wiring must conform to local electrical codes. If the supply cord is damaged, it must be replaced by the manufacturer, stocking distributor, or authorized repair center in order to avoid a hazard.
Flooding:
WARNING: Install this pump in a location where flooding cannot occur.
Ground Fault Circuit Interrupter:
WARNING: To reduce the risk of electric shock, install only on a circuit protected by a Ground Fault Circuit Interrupter (GFCI).
Line Depressurization: To reduce the risk of chemical splash during disassembly or maintenance, all installations should be equipped with line depressurization capability.
Over Pressure Protection: To ensure safe operation of the pump it is recommended that some type of safety / pressure relief valve be installed to protect the piping and other system components from failing due to excessive pressure.
Flow Display: The accuracy of the flow value as shown on the pump display is highly dependent on the specific application. Calibration is necessary in order to display an accurate measure of the flow.
Chemicals: Safety procedures for hazardous fluids must be put in place to protect against injury to personnel. Operation of the pump after failure of the peristaltic tube can cause buildup of chemical in the pumphead. Some pumphead parts may not be compatible with certain aggressive chemicals. This can cause damage to the pumphead components, and pump internals if chemical spills are not promptly addressed.
CAUTION: Spills of Dangerous chemicals should be cleaned up immediately.
Lifting, transportation, installation, starting-up, maintenance and repair should be performed by qualified personnel only. The unit should be electrically isolated while work is being carried out.
There is a replaceable fuse on the I/O Board.

Installation

4.1 | POWER REQUIREMENTS
Electric shock is a real possibility with any electrical device. Grounding conductors and grounding-type attachment plugs are included with pumps. To reduce risk of electric shock, ensure that it is connected to a properly grounded receptacle.
Use correct supply voltage. Using incorrect voltage will damage pump and may result in injury.
Ensure that all electrical cable glands are placed and sealed appropriately. Never connect power and control cables together.
Equipment may start automatically. This pump has a user-selectable automatic restart capability that can either put the pump back in operation after a power outage or restart it completely.
If in doubt, contact a certified electrician.
4.2 | CONTROL WIRING

Remove the pump terminal box for access to the control terminals.
Conduit holes are 3/8” and ½”. Use appropriate cable glands to ensure proper sealing is achieved.
For safety, do not apply 110-230VAC to control terminals. Signals applied to terminals must be within appropriate limits. Damage from misapplied signals can destroy the pump and is not covered under warranty.

4.3 | BEST PRACTICES
Peristaltic pumps are self-priming and do not allow backflow up to rated pressure. No valves are required in inlet or discharge line, however may be useful in some circumstances:

• In case of a pumphead or tube failure, users can install a check valve between the pump and the discharge pipework to prevent pressurised fluid from backflowing.
• Any valves in the process flow must be open before starting the pump. Include a pressure relief device in the discharge line prior to any valves to protect against damage caused by accidental operation against a closed valve.

Tube selection: Refer to the LMI Pump website for a chemical compatibility guide. For help with compatibility issues, contact a distributor or LMI Pump customer care.
In normal operation, the pump rotates in a counter-clockwise direction and the ports are left-facing. In this configuration, the bottom port is used for suction, and the top port is used for discharge. However, pump has no impact on performance if the pump is configured to run in either direction.
Install the pump on a stable and level horizontal surface. Pump is equipped with rubber feet, however if desired, the pump includes threaded holes on the bottom that could be used to bolt the pump in place.
In order to allow the pump to dissipate heat, ventilation is crucial. Keep dirt and dust out of the pump enclosure.
Ambient temperature (surrounding temperature) should be within the recommended limits.
Do not stack pumps.
Keep the pipes for suction and discharge as short and straight as possible.
Use bends with a big radius, at least four times the tube diameter.
Use of suction pipe or tube with a bore smaller than the pump tube bore should be avoided.
Connect the pump to the hard pipe using a flexible tubing portion to reduce any pulsation and make it easier to access the pumphead.
The pump can lift 10 feet or more of suction depending on which tube is installed. For maximum performance and longest tube life, a slightly flooded suction is recommended.
After changing a tube or any application or process, calibrate the pump. To keep accuracy, calibrate on a regular basis.
When pumping viscous fluids:

• Use tubes or pipes several times larger than the pump tube for suction and discharge.
• Run the pump slowly.
• Maximize NPSHa

Troubleshooting

8.1 | TROUBLESHOOTING GUIDE

Viscosity too high.

| Run pump slower to allow more time for tube to restitute.
Select larger tube and run slower.
Improve suction pressure.
Poor suction conditions.| Run pump slower to allow more time for tube to restitute.
Ensure fittings and connections are tight so that no air may enter suction line.
Clean suction strainer (if used).
Increase tank level and/or tank height.
Apply best hydraulic practices – use large pipework, minimize pipe length, reduce obstructions, and use a suction accumu- lator.
Check suction line for obstructions.
Tube dimensions do not match the specifications of the rotor assembly.| Install matched roller assembly and tube.
Discharge pressure too high, causing excessive backflow.| Reduce discharge pressure.
Decrease friction losses in discharge pipework.
Using third-party tubing.| Use only LMI tube assemblies.
Tube obstruction.| Check tube for obstructions.
Pump not properly calibrated.| Perform calibration under application conditions per O&M.

**** Tube Fails Prematurely.

| Tube not installed correctly.| Check installation of tube.
---|---|---
Fluid temperature too high.| Reduce fluid temperature.
Mechanical damage to tube from solids.| Use suction strainer to prevent solids from entering pump.
Possible chemical attack.| Check compatibility of tube material with product being pumped.
Operating pressure too high.| Reduce discharge pressure.
Tube dimensions do not match the specifications of the rotor assembly.| Install matched roller assembly and tube.
Excessive Noise and/or Vibration.| Tube dimensions do not match the specifications of the rotor assembly.| Install matched roller assembly and tube.
Loose fittings and/or pipework.| Ensure fittings are tight and pipework is properly secured and supported.
Pulsation – wide swing in discharge pressure during operation.| Apply best hydraulic practices – use large pipework, minimize pipe length, reduce obstructions, and use a pulsation damp- ener.
Tube Leak Not Detected.| Optical sensor is dirty.| Clean contamination from the surface of the optical sensor.
High Pump Temperature| Rotor assembly is worn.| Check that all rollers are free to spin and that there is no inter- ference or binding of the rotor assembly within the pumphead or front cover.
Fluid temperature too high.| Reduce fluid temperature.
High discharge pressure or poor suction conditions.| Reduce discharge pressure and/or improve suction conditions.
**** Ambient temperature too high.| Operate within recommended limits.
Locate pump out of direct sunlight.
Locate pump away from other equipment which may be hot.
