INSTALLATION
A check valve in the discharge line is normally rec
ommended, but it is not necessary in low dis
charge head applications.
With high discharge heads, it is recommended that
a throttling valve and a system check valve be in
stalled in the discharge line to protect the pump
from excessive shock pressure and reverse rota
tion when it is stopped.
If the application involves a high discharge
head, gradually close the discharge
throttling valve before stopping the pump.
Bypass Lines
If it is necessary to permit the escape of air to atmo
sphere on initial priming or during the repriming
cycle, install an air bypass line ‐ sized so that it will
not affect the pump discharge capacity ‐ between
the pump and the discharge check valve. Since
this pump does not use a suction check valve, the
discharge end of the bypass line must be sub
merged in the liquid being pumped in order to
maintain suction.
NOTE
The bypass line may clog frequently if the liquid
contains solids and the valve remains closed. If this
condition occurs, either use a larger bypass line or
leave the shut‐off valve open during pumping.
ELECTRICAL CONNECTIONS
This pump is driven by an electric motor. Check
that the electrical service available matches the
motor requirements stamped on the motor name
plate before connecting the motor to the incoming
power.
The electrical power used to operate the
pump is high enough to cause injury or
death. Obtain the services of a qualified
electrician to make all electrical con
nections.
Do not install and operate a non‐explo
sion proof motor in an explosive atmo
sphere. Install, connect, and operate
the motor in accordance with The Na
tional Electric Code and all local codes.
If there is a conflict between the instruc
tions in the manual accompanying the
unit and The National Electric Code or
the applicable local code, The National
or local code shall take precedence.
Refer to the following motor data before making
electrical connections.

GROUNDING
Because this pump is used to handle volatile or
flammable liquids, the unit must be grounded by
attaching a ground wire assembly to a ground rod
in order to eliminate electrostatic build‐up by the
liquid being pumped. Install the ground rod in ac
cordance with the National Electrical Codes and all
local codes. Be sure the fastening device makes a
tight electrical connection with the rod and the
pump.
Inspect and test the ground wire assembly
for conductivity. Replace a broken or
frayed wire before resuming operation.
