PREPARING TO START THE PUMP
NEVER RUN PUMP DRY. Running pump without
water may cause pump to overheat, damaging seal and possibly
causing burns to persons handling pump. Fill pump with water
before starting.
NEVER RUN PUMP AGAINST CLOSED DISCHARGE.
To do so can boil water inside pump, causing hazardous
pressure in unit, risk of explosion and possibly scalding persons
handling pump.
NOTE: Open water system faucets before priming pump for the
first time.
1.
Remove pressure gauge.
a. Close regulator valve (turn clockwise - see Figure 13).
b. Fill pump and suction pipe with water (Figure 13).
c. Replace pressure gauge, using PTFE pipe thread
sealant tape on thread; tighten gauge.
IMPORTANT: If a priming tee and plug have been provided for a
long horizontal run, be sure to fill suction pipe through this tee
and replace plug. (Do not forget to PTFE pipe thread sealant
tape the plug.)
2.
Start pump: Pressure should build rapidly so 50 pounds per
square inch or more as ejector and pump prime.
IF NO PRESSURE OR NO WATER, REPEAT Step No.1 (above) two
or three times to remove entrapped air from the suction pipes.
3.
If, after priming pump several times, no water is pumped,
check the following:
a. Suction pipe in the water and has no leaks.
NOTE: Air can leak in even where water won't leak out.
Make sure all joints are tight.
b. Control valve, check valve, or foot valve installed
and opertating correctly.
c. Pump trying to lift water more than 25 feet (shallow
well) or more than rated lift for deep well ejector used
(including compensation for horizontal offset).
d. Be sure pump is not air locked. In offset installations,
pump suction port should be highest point in suction
pipe; there should be no sags in suction pipe (run it
straight and at a slight angle upward from well
head to pump).
NOTE: For deep well installation, go to Step 4 (Page 12). Shallow
well installations go to Step 6 (page 12).
