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
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 2SV 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 2SV 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 2SV only) and open the suc-
tion valve.
4. OPERATION
DO NOT OPERATE UNIT WITH-
OUT SAFETY GUARD IN PLACE.
TO DO SO CAN CAUSE SEVERE
PERSONAL INJURY.
NOTICE: PUMP MUST BE COMPLETELY PRIMED
BEFORE OPERATION.
DO NOT OPERATE PUMP AT OR
NEAR ZERO FLOW. TO DO SO
CAN CAUSE EXTREME HEAT,
DAMAGE TO THE PUMP, INJURY
OR PROPERTY DAMAGE.
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-92SV 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.
CAUTION
Hazardous machinery
can cause personal
injury or death.
WARNING
Extreme heat can
cause personal injury
or property damage.
WARNING
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.
HAZARDOUS MACHINERY.

TORS CAN RESTART MOTOR
UNEXPECTEDLY AND WITH-
OUT WARNING, CAUSING
SEVERE PERSONAL INJURY.
See the “ENGINEERING DATA” section in this
manual for the recommended maximum pump starts
per hour.
DISCONNECT AND LOCKOUT

CAN CAUSE SHOCK, BURNS OR
DEATH.
MOTOR LUBRICATION
Recommended Motor Bearing Lubrication Intervals
Interval Service Environment
1 – 2 Years Light Duty in Clean Atmosphere
1 Year 8 – 16 hours/day – Clean, Dry Atmosphere
6 Months 12 – 24 hours/day – Moisture Present
3 Months 12 – 24 hours/day – Dirty, High Moisture
When lubricants are operated at elevated tempera-
tures, the lubrication frequency should be increased.
DO NOT intermix grease bases (lithium, sodium,
etc.). Completely purge old grease if changing grease
base.
Over greasing can cause excessive bearing tempera-
tures, lubricant and bearing failure.
1. Close all necessary suction and discharge valves.
2. Drain the liquid from the pump by removing the
lower drain plug and the upper vent plug.
3. Remove the coupling guards, the 4 coupling hex
cap screws, the coupling and coupling drive pin.
4. Remove the 4 motor hex cap screws. On units
with motor frames 213TC and larger, remove the
4 motor adapter flange hex cap screws. With an
