Cleaning Safety
Procedures
Manual Cleaning
Address the following considerations when manually cleaning
your pump:
1. Do not use toxic and/or flammable solvents.
2. Lock out electrical power and shut off all air prior to cleaning
the equipment.
WARNING: To prevent an acci-
dental start-up, lock out the power
source with lock and key. 3. Keep electrical panel covers closed and power off when
washing the equipment.
4. Clean up spills as soon as possible.
5. Never attempt to clean the equipment while it is operating.
6. Wear proper protective clothing.
Cleaning-In-Place (CIP)
When performing CIP do the following:
1. Make certain that all connections in the cleaning circuit are
properly applied and tight to avoid contact with hot water or
cleaning solutions.
2. When cleaning cycle is controlled from a remote or auto-
mated cleaning center, establish safe procedures to avoid
automatic start-up while servicing equipment in the circuit.
Preliminary Test Run
Test the system using a preliminary run with the materials that will
be pumped.
DO NOT run the pump at this time to produce final
product.
See “Starting the Pump” on page 27.
Check For Possible Motor Overload Conditions
Certain combinations will overload the motor when operated with
open unrestricted discharge, resulting in an unacceptably high
flow rate. Additional discharge restriction may be required to
lower the flow rate and lower the horsepower requirement.
DO
NOT add a restriction to the supply line. If the pump was incor-
rectly selected, a smaller impeller or a higher motor horsepower
may be required.
If you are uncertain about pump selection and application, tempo-
rarily install an ammeter in the electrical service.
Ammeter Test
DANGER: To avoid electrocution and equipment damage,
only a qualified electrician should install the ammeter.
Operate the pump under process conditions and check the motor
amp draw versus the nameplate full load rating. If the amp draw
exceeds the motor rating, a system change or pump change is
required.
If the process conditions and/or the liquid changes (higher viscos-
ity, higher specific gravity) recheck the motor amp draw.
