CLEANING SAFETY AND TEST RUN
AMMETER TEST
Operate pump under process conditions and
check motor amp draw versus nameplate full
load rating. If amp draw exceeds motor rating,
a system change or pump change is required.
If process conditions and/or liquid changes,
(higher viscosity, higher specific gravity)
recheck motor amp draw.
Contact your authorized TOP LINE distributor
for assistance.
WARNING
TO AVOID ELECTROCUTION, ONLY
A QUALIFIED ELECTRICIAN SHOULD
INSTALL THE AMMETER.
OPERATION
• Any system throttling valves, or similar
devices used to control flow rate must
be installed in the discharge line, not the
supply line. Restriction in the supply line
may cause cavitation and pump damage.
• “Water hammer” in the system can
damage the pump and other system
components. Water hammer often occurs
when valves in the system are suddenly
closed causing lines to move violently and
with a loud noise. When this condition is
present, find and eliminate the source of
the water hammer. One way to eliminate
water hammer is to slow down the
actuation speed of the valve.
• Do not expose the pump to freezing
temperatures with liquid in the casing.
Frozen liquid in the casing will damage
the pump. Drain casing before exposing
to freezing temperatures.

OPERATION
CLEANING SAFETY PROCEDURES
Manual Cleaning:
1. Do not use toxic and/or flammable solvents.
2. Lock out electrical power and shut off all air
prior to cleaning equipment.
3. Keep electrical panel covers closed and
power off when washing equipment.
WARNING
To prevent an accidental start-up
the power source should be locked
out using your lock and key.
4. Clean up spills as soon as possible.
5. Never attempt to clean the equipment while
it is operating.
6. Wear proper protective apparel.
Cleaning-In-Place
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 the cleaning cycle is controlled from
a remote or automated cleaning center,
follow all established safety procedures for
servicing the system.
PRELIMINARY TEST RUN
See OPERATION on page 10 to set pump up
for a test run.
CHECK FOR POSSIBLE MOTOR
OVERLOAD CONDITION
Certain combinations will overload the motor
when operated with open, unrestricted
discharge, which results in a high flow rate.
Additional discharge restriction may be required
to lower the flow rate and lower the horsepower
requirements. DO NOT add restrictions to the
supply line. If the pump was incorrectly sized, a
smaller impeller or a higher horsepower motor
may be required.
If uncertain about pump selection and
application, temporarily install an ammeter in
the electrical service to check the amp draw.
It is not necessary to disassemble the pump for
cleaning if used in a CIP Installation (Clean-In-Place).
However, periodically take pump apart, thoroughly
inspect, clean and reassemble.
