from the overload
relay.
d. Locate the motor
name plate on the
pump motor housing
(figure 3.2D). The full
load amp rating for
the motor is listed on
the name plate.
e. Engage the
electrical power
supply and start the
unit.
f. The amp meter will display the motor amps.
Compare the actual motor amps as displayed on
the amp meter to the full load amp rating as listed
on the motor name plate.
g. If the amp draw is excessive (higher than the listed
name plate amp rating), a throttling valve must
be installed in the “from process” water line. The
throttling valve can be a gate valve or a ball valve.
h. With the throttling valve installed, fully close the
valve and then engage the pump motor. Slowly
open the throttling valve and monitor the motor
amps as displayed on the amp meter until the
actual motor amps equal the listed full load amp
rating of the motor. The process flow is now
correctly adjusted. The valve should remain in this
position during operation.
6. LOW PROCESS FLOW: The minimum recommended
process flow rate is 10 GPM. Process restrictions may limit
the flow to less than 10 GPM. We recommend the addition
of bypass lines to raise the flow rate to 10 GPM. The best
place to add bypass lines are on the extra ports on the
molding machine manifold. If extra ports are not available,
add a tee in the To Process and From Process lines, install
