Water Connection; Wiring And Grounding - ITT G&L Serie Directives D'installation, D'utilisation Et D'entretien

For the 33 through 92SV 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.
Install the 2 coupling guard halves.

1. WATER CONNECTION

The water connections must be made by qualifi ed
installation technicians in compliance with the regu-
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-
fl ow prevention device, such as a disconnector, check
valve or disconnection tank .

servicing pump.
Electrical supply MUST match pump's name-
plate specifi cations. Incorrect voltage can cause
fi re, 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.

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 fl ow 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 qualifi ed electrician interchange
any two of the three power cable leads.
3. PRIMING/VENTING
For installations with the liquid level above the pump:
Close the discharge valve.
Remove the vent plug.
For models 1SV and 2SV only, it is necessary to
fully unscrew the pin located in the drain plug.
See fi gure below.
DRAIN PLUG
WITH PIN CLOSED
For sizes 33SV-92SV 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-92SV ,
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 fl ows out of
the vent plug opening.
