WARNING
– Return to filter to close filter manual air relief valve when a steady stream of water
(not air or air and water) is discharged from valve. Failure to do so could result in severe personal
injury.
ATTENTION
–
NEVER OPERATE THE PUMP WITHOUT WATER
. Water acts as a
coolant and lubricant for the mechanical shaft seal. NEVER run pump dry. Running pump dry may
damage seals, causing leakage, flooding, and voids warranty. Fill strainer housing with water before
starting motor.
ATTENTION
– Do NOT add chemicals to the system directly in front of pump suction. Adding
undiluted chemicals may damage pump and voids warranty.
ATTENTION
– Before removing strainer cover:
1.
STOP PUMP before proceeding.
2.
CLOSE VALVES in suction and outlet pipes.
3.
RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See
filter owner’s manual for more details.
4.
If water source is higher than the pump, pump will prime itself when suction and outlet valves are
opened. If water source is lower than the pump, unscrew and remove strainer cover; fill strainer
housing with water.
5.
Clean and lubricate strainer cover O-ring with Krytox GPL203 grease if necessary.
6.
Replace strainer cover on strainer housing; turn clockwise to tighten cover.
NOTE - Tighten strainer cover lock ring by hand only (no wrenches).
Turn on power and wait for pump to prime, which can take up to fifteen (15) minutes. Priming time will
depend on vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime
within 15 minutes, stop motor and determine cause. Be sure all suction and discharge valves are open
when pump is running. See Troubleshooting Guide.
