Final Test Procedures 12–3
Test Run
A test tank and panel (available from E/One) are recommended for run-testing the pump. The
test tank has a discharge assembly for D-Series pumps, or slide face the W-Series pumps. A
pressure gauge and ball valve should be added to operate the pump under pressure. A two-
tank setup with sump pump to pump water back to the test tank is ideal. Contact the E/One
eld service department for assistance. Testing the pump is crucial.
1. Set the pump in the test tank and ll with water to the alarm level. Connect the EQD.
2. Open the discharge valve.
3. Hook the Amp probe around the black power lead to the pump (see Amperage Draw
Test).
4. Turn on the alarm power circuit breaker and verify the alarm is functioning.
5. Turn on the pump power circuit breaker. The pump should turn on immediately.
At 0 psi, the alarm should turn off in one to two minutes; the pump within 30 to 45
seconds after the alarm.
6. Leave the circuit breakers on. Fill the tank until the pump turns on. Close the
ball valve until the pressure gauge reads 40 psi. The pump should shut off in
approximately 45 seconds (in a 24-inch diameter tank).
7. Fill the tank again until the pump turns on. Carefully close the ball valve until the
gauge reads 35 to 40 psi. The pump should shut off in approximately one minute.
The unit must be tested to pump against discharge pressure; note the amperage
draw at each pressure.
Note: The unit pumps approximately 15 gpm at 0 psi discharge pressure; 11 gpm at 40 psi; and
approximately 9 gpm 60 psi. Flow can be checked with a 5 gal pail and a stop watch (15
gpm = 20 seconds; 11 gpm = 28 seconds; 9 gpm = 34 seconds)
Amperage Draw Test
1. Set the clamp on amp meter to the desired scale.
2. Hook the probe around the black power lead in the control panel.
3. With the power on, ll the tank until the pump operates.
4. Read the current directly. Refer to the following table for troubleshooting information.
The gures shown are averages and meant to be used for approximation since motors,
voltages and amp meters vary. For a 120-volt pump, double the amperage shown in table.
The table displays a comparison of back pressure (psi), ow (gpm), current draw (amperes)
and head (feet of water pressure). By knowing the current draw, you may discover a restricted
or blocked discharge line, blown pump stator, high head operation, etc.
WARNING!
Do not “dead head” the pump by closing the valve
completely. Damage and personal injury could occur.
