NOTE: Place a loose rag over the open vent port to pre-
vent large amounts of liquid from being sprayed
on the pump and adjacent equipment.
Care should be exercised if you
CAUTION
are pumping hot water or chemi-
cals to avoid personal injury.
Install and torque the vent plug to the values
provided in the "ENGINEERING DATA" sec-
tion of this manual. Close the drain plug pin
(1SV and SV only) and open the discharge
valve.
For installations with the liquid level below the
pump:
Install foot valve at suction end.
For models 1SV and SV only, it is necessary to
fully unscrew the pin located in the drain plug.
See figure on previous page.
With the provided plastic funnel, completely fill
the casing with liquid.
Install and torque the vent plug, close the drain
plug pin (1SV and SV only) and open the suc-
tion valve.

Start the pump, keeping the on-off valve down-
stream from the pump closed. Open the on-off
valve gradually. The pump must run smoothly and
noiselessly. If necessary, reprime the pump. Check
the current absorbed by the motor and, if neces-
sary, adjust the setting of the thermal relay. Any air
pockets trapped inside the pump may be released by
loosening the fill plug, for the 1SV-4SV pumps, or by
turning the air screw for the 33SV-9SV pumps .
If a pump installed in a location

where freezing may occur remains
inactive, you must drain it through the drain plugs.
This operation is not necessary if a suitable anti-
freeze has been added to the water.

Make sure that the drained liquid does not
cause damage or injuries.
After stabilizing the system at normal operating
conditions, check piping for correct alignments. If
necessary, adjust pipe supports.

DO NOT intermix grease bases (lithium, sodium,
etc.). Completely purge old grease if changing grease
base.
Over greasing can cause excessive bearing tempera-
