CAUTION:
All pumps must be primed by
filling the pump cavity with water before they
are first operated. This may take several gallons
of water, as the entire inlet line will be filled in
addition to the pump cavity. The longer the inlet
line, the more water is required for priming.
1. Disconnect the 1-1/2 in. outlet union and
separate the pipe.
2. Remove the air relief plug on top of pump and
the 1-1/4 in. priming plug with pressure gauge
or plug. Refer to Pump Preparation Step 5
.
3. Slowly
fill pump cavity until water comes out
of air relief hole on top of the pump.
4. Replace air relief plug and continue adding
water to pump cavity until water comes out of
the open outlet pipe at the open union.
5. Wait 10 minutes to see if water level drops
below the pipe tee. If level drops, check foot
valve. If level stays constant, replace the
priming plug.
6. Reconnect 1-1/2 in. union on outlet pipe.
Open the ball valve (turn handle to line up
with pipe), and then turn on breaker to start
pump.
IMPORTANT:
If the pump fails to prime
within five minutes:
7.
Turn the power off at the break box. Check
all pipe connections for leaks, making sure
all connections are water and air tight.
Check the inlet pipe for any sagging, making
sure the inlet pipe is in a straight line to the
pump. Watch for leaks or a milky color in
the discharged water, which indicated an air
leak. Re-prime if necessary, following steps
1 through 6 above. Reset breaker at the
breaker box.
IMPORTANT:
If the pump hums instead of
pumping or turns off repeatedly, shut pump off
immediately. Check voltage. Pump is wired to
run on 230 volts. If the pump cuts out or stops,
you may be attempting to connect to 115 volts.
See PUMP ELECTRICAL INSTRUCTIONS to
see how to correctly change the motor voltage to
115 volts.
