7. Return the system to operating conditions and reconnect the power to the pump.

The pump is now ready for priming and operation. Always use caution and check for leaks at newly assembled

connections.

Air Bleed Operation:

1. While pump is running, turn the bleed valve knob counter clockwise.

2. Run with valve open until a solid stream of fluid comes out of the bypass tubing (.38inch tubing supplied with valve)

3. Close air bleed valve by turning the bleed valve knob clockwise.

 HAND TIGHTEN FITTINGS:

When connecting tubing to suction and discharge fittings, the coupling nuts should be tightened hand tight only. Excessive

tightening can cause cracks in pump head.

 POINT OF INJECTION:

Pipe corrosion can result if dillution at the injection point does not occur rapidly. This problem is easily prevented by

observing this simple rule: install injection fitting so that the end is in the flow stream of the line being treated. NOTE:

Extended injection assemblies are available for large water lines. Consult your dealer.

 COMMON ERRORS IN THE INJECTION OF CHEMICALS:

Do not insert the injection fitting into a pipe stub in the tee. A full strength solution will often cause corrosion or scale in the

pipe stub when it is not in the flowing stream (Figure J). The maximum lift of the chemical feeder is five feet. Be sure not

to exceed this height. It is very important that the arrow on the fittings and the pump head point vertically upward

in order to prevent backflow. Arrows indicate the proper flow of the chemical.

POWER

The standard chemical feeder is available in115 volt 60 cycle single phase. 230 volt 60 cycle and 230 volt 50 cycle single

phase can also be made available upon request.

Be sure the voltage of the feeder matches the power supply. (Figure M)

When working on or around metering pump installation, protective gloves and safety glasses should be worn at

all times.
