6EC - 10EC Series

Operation

1. Pump must be installed in a suitable gas tight basin which is at least 18" in diameter and 24"

deep, and vented in accordance with local plumbing codes.

2. Pump features a 1-1/2" female NPT discharge.

3. Pump must be placed on a hard level surface. Never place pump directly on clay, earth or

gravel surfaces.

4. A check valve must be used in the discharge line to prevent back flow of liquid into the basin.

The check valve should be a free flow valve that will easily pass solids.

CAUTION: For best performance of check valves, when handling solids install in a horizontal

position or at an angle of no more than 45°. Do not install check valve in a vertical position, as

solids may settle in valve and prevent opening on start-up.

5. Do not attempt to restrict the intake side of these pumps. Restricting the intake may cause

damage to the seal and may starve the pump. If you require reduced flow rates, then place

a valve on the discharge side of the pump or if flexible vinyl tubing is used, a clamp can be

used on the tubing to restrict the flow.

6. Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid. You

may damage the seal and the motor may fail if the pump is allowed to run dry.

7. If the unit is going to be idle for a period of time, follow the cleaning instructions outlined

in the next section. Do not let the unit freeze in the wintertime. This may cause cracking or

distortion that may destroy the unit.

Testing Pump Operation

CIA Series Effluent Pumps

1. These pumps are equipped with a float operated mechanical switch.

2. When these pumps are installed in a basin with a sealed cover, switch operation cannot be

observed. The sump cover usually will have an additional opening that is plugged with a

rubber plug. This plug can be removed and switch operation can be observed.

3. Plug power cord into a grounded receptacle with voltage consistent with pump voltage as

indicated on pump nameplate.

4. Run water into pump until pump starts.

5. Be sure gate valve in discharge line is open.

6. Allow pump to operate through several on off cycles.

CIM Series Effluent Pumps

1. The pump cord for these pumps can be plugged directly into a properly grounded receptacle

with voltage consistent with pump nameplate for continuous pump operation.

CAUTION: This type of operation should be used only for emergency use or when a large volume

of water is to be pumped. Pump must not be allowed to run dry. If pump is run dry, it may damage

pump and void the warranty.
