Hazardous voltage

can shock, burn or

cause death.

For the 33 through 9SV sizes using a cartridge seal, 

after coupling bolts have been properly torqued, 

there are four set screws on the collar of the car-

tridge seal that require tightening before removing 

the shim. The four hex head set screws require a 1/8" 

allen wrench and are to be tightened hand-tight ap-

proximately 5 lbs.-ft. (7 N

Remove the motor assembly shim and retain for 

future use.

lations in force.
In case of connection to the water system, the regu-

lations issued by the competent authorities (mu-

nicipal, public utility company) must be observed. 

Authorities often require the installation of a back-

flow prevention device, such as a disconnector, check 

valve or disconnection tank.

Install, ground and wire accord-

ing to local and  National Elec-

trical Code requirements.

Install an all leg disconnect 

switch near pump.

Disconnect and lockout electri-

cal power before installing or 

servicing pump.

Electrical supply MUST match pump’s name-

plate specifications. Incorrect voltage can cause 

fire, damage motor and voids warranty.

Motors equipped with automatic thermal pro-

tectors open the motor’s electrical circuit when 

an overload exists. This can cause the pump to 

start unexpectedly and without warning.

Use only stranded copper wire to motor and ground. 

Wire size MUST limit the maximum voltage drop to 

10% of the motor nameplate voltage, at the motor 

terminals. Excessive voltage drop will affect perfor-

mance and void motor warranty. The ground wire 

must be at least as large as the wires to the motor. 

Wires should be color coded for ease of mainte-

nance.
Three phase motors require all leg protection with 

properly sized magnetic starters and thermal over-

loads.

Connect the electrical leads to the motor, as follows:

Hazardous

Single Phase Motors – Connect the BLACK wire to 

the BLACK motor wire. Connect the WHITE wire 

to the WHITE motor wire. Connect the GREEN 

wire to the GREEN motor wire.
Three Phase Motors – See figure below.

NOTICE: UNIT ROTATION IS DETERMINED WHEN 

VIEWED FROM MOTOR END. SEE PAGE 16 

FOR MOTOR ROTATION DETAIL. INCOR-

RECT ROTATION MAY CAUSE DAMAGE TO 

THE PUMP AND VOIDS WARRANTY.

Check pump rotation by observing the motor fan or 

the coupling THROUGH the coupling guard. DO 

NOT confuse the flow arrows, stamped on the pump 

body, with the rotation arrows on the coupling and 

motor adapter. Three phase motors only – If rotation 

is incorrect, have a qualified electrician interchange 

any two of the three power cable leads.

For installations with the liquid level above the pump:

Close the discharge valve.
Remove the vent plug.
For models 1SV and SV only, it is necessary to 

fully unscrew the pin located in the drain plug. 

See figure below.

For sizes 33SV-9SV the vent plug is supplied 

with an internal needle valve, so it is not neces-

sary to remove the vent plug. Simply unscrew 

the needle valve half way to open the valve 

to allow air to escape. (For sizes 33SV-9SV, 

if the pump is supplied with a cartridge seal, 

remove the vent plug located on the gland plate 

beneath the coupling.)
Open the suction valve until liquid flows out of 

the vent plug opening.
