PRECAUTIONS FOR OPERATION
Each Electronic Metering Pump has been tested to meet prescribed specifications and safety standards. Proper care
in handling, installation and operation will help in ensuring a trouble free installation.
Please read all these cautionary notes prior to installation and start-up of your metering pump.
1. Important: Pump must be installed and used with supplied back pressure/injection valve. Failure to do
so could result in excessive pump output flow.
2. Handle the pump with care. Dropping or heavy impact causes not only external damage to the pump, but also to
electrical parts inside.
3. Install the pump in a place where the ambient temperature does not exceed 40°C (104°F). The pump is water
resistant and dust proof by construction and can be used outdoors, however do not operate the pump
submerged. To avoid high internal pump temperatures, do not operate in direct sunlight.
4. Install the pump in a place convenient for its future maintenance and inspection, then fix it to prevent vibration.
5. Protective caps must be removed prior to installing tubing onto valve assemblies. Use tubing of specified size.
Connect the tubing to the suction side securely to prevent the entrance of outside air. Make sure that there is no
liquid leakage on the discharge side.
6. Be careful to check that the voltage of the installation matches the voltage indicated on the pump nameplate.
Each pump is equipped with a three prong plug. Always be sure the pump is grounded. To disconnect, do not
pull wire but grip the plug with fingers and pull out. Do not use the receptacle in common with heavy electrical
equipment which generates surge voltage. It can cause the failure of the electronic circuit inside the pump.
7. Tampering with electrical devices can be potentially hazardous. Always place chemicals and pump installation
well out of the reach of children.
8. Never repair or move the metering pump while operating. Always disconnect electrical power. For safety,
always wear protective clothing (protective gloves and safety glasses) when working on or near chemical
metering pumps.
9. An air bleed valve is available for most models with tubing connections. Air purges should be performed when
the pump chamber contains no fluid at the time of start-up. As a safety measure, connect the return tubing to the
air bleed valve and bypass fluid back to storage tank or a suitable drain.
10. Chemicals used may be dangerous and should be used carefully and according to warnings on the label. Follow
the directions given with each type of chemical. Do not assume chemicals are the same because they look alike.
Always store chemicals in a safe location away from children and others. We cannot be responsible for the
misuse of chemicals being fed by the pump. Always have the material safety data sheet (MSDS) available for
any fluid being pumped.
11. All pumps are pretested with water before shipment. Remove head and dry thoroughly if you are pumping a
material that will react with water, (i.e. sulfuric acid, polymers). Valve seats, ball checks, gaskets, and diaphragm
should also be dried. Before placing pump into service, extreme care should be taken to follow this procedure.
12. Valve cartridges are stamped to indicate fluid flow direction. Always install so that markings read from top to
bottom, with the arrow pointing in the direction of flow.
13. When metering hazardous material DO NOT use plastic tubing, strictly use proper rigid pipe. Consult supplier for
special adapters or valve assemblies.
14. Pump is NOT to be used to handle or meter flammable liquids or materials.
15. Standard white discharge tubing is not recommended for installations exposed to direct sunlight. Consult
supplier for special black tubing.
16. Factory will not be held responsible for improper installation of pump, or plumbing. All cautions are to be read
thoroughly prior to hook-up and plumbing. For all installations a professional plumber should be consulted.
Always adhere to local plumbing codes and requirements.
