The following precautions should be taken when working with all metering 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. Addition
al precautions should be taken depending on the solution being pumped. Refer
to Material Safety Data Sheets for the solution being pumped.
Hearing Protection
!
It is recommended that hearing protection be used if the pump is in an environment where the time-
weighted average sound level (TWA) of 85 decibels is exceeded. (as measured on the A scale -- slow
response)
Electrical Safety
!
• Remove power and ensure that it remains off while maintaining pump.
• DO NOT FORGET TO
CONNECT THE PUMP TO EART
H
• Electric protection of the motor (Thermal protection or by means of fuse
s) is to correspond to
the rated current indicated on the motor data plate.
Liquid Compatibility
!
Verify if the materials of construction of the wetted components
of your pump are recommended for the
solution (chemical) to be pumped.
Pumps Water “Primed”
!
All pumps are tested with water at the factory. If your process solu
tion is not compatible with water, flush
the Pump Head Assembly with an appropriate solution before introducing the process solution
Plumbing and Electrical Connections
!
Always adhere to your local plumbing and electrical codes.
Line Depressurization
!
To reduce the risk of chemical contact during disassembly or maintenance, the suction and discharge
lines should be depressurized before se
rvicing.
Over Pressure Protection
!
To ensure safe operation of the system it is recommended that some type of safety/pressure-relief valve
be installed to protect the piping and other system components from damage due to over-pressure.
Lifting
!
This manual should be used as a guide only - Follow your company’s recommended lifting procedures. It
is not intended to replace or take precedence over recommendations, policies and procedures judged as
