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 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
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.

When lubricants are operated at elevated tempera- tures, the lubrication frequency should be increased.
NOTICE: PUMP MUST BE COMPLETELY PRIMED BEFORE OPERATION.
DO NOT intermix grease bases (lithium, sodium, etc.). Completely purge old grease if changing grease base.
WARNING
Extreme heat can cause personal injury or property damage.
DO NOT OPERATE PUMP AT OR
NEAR ZERO FLOW. TO DO SO 0 CAN CAUSE EXTREME HEAT, DAMAGE TO THE PUMP, INJURY OR PROPERTY DAMAGE.
Over greasing can cause excessive bearing tempera- tures, lubricant and bearing failure.
