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.
