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.
17. When using pump with pressurized systems, make sure the pressure of the system does not exceed
the maximum pressure rating on the pump nameplate. Be sure to de-pressurize system prior to hook
up or disconnecting the metering pump.
18. Electronic power modules are equipped with automatic reset thermal overload devices and may reset
unexpectedly.
19. The pump is designed to operate using a backpressure/injection valve. If the discharge point is below
the liquid level of the source or if the discharge pressure is less than the suction pressure, siphoning
may occur. To correct this condition, install an anti-siphon valve or other anti-siphon device. Check
local regulations which may apply. (Ref. Figure G1).
20. If the power cord is unplugged or in the event of electrical power interruption while the pump is operating,
the pump will remember its last operating state for years and will resume operation as before, whenever
power is restored.
