INTRODUCTION

We suggest you take a few minutes to read the instructions con-

tained in this manual before installing and using your pump. This will help you obtain the full benefits of the quality and convenience

built into this equipment. It will also help you avoid any needless

service expense resulting from causes beyond our control which

naturally cannot be covered in our warranty.

MAJOR COMPONENTS / PIPING

MAJOR COMPONENTS AND WHAT THEY DO

NOTICE: Use Teflon tape supplied with the pump for making all

threaded connections to the pump.

Impeller and Jet

Impeller turns with motor shaft, causing water to fly out from its

rim by centrifugal force. Impeller rotation creates a vacuum which

pulls in more water. Part of the water is diverted back to the jet

where it passes	through		the nozzle and		venturi.		This	creates more
vacuum to draw in more water.
In shallow wells	(less	than	20 feet	deep),	the	vacuum		created		at	the
pump is enough	to	pull	water to	the pump.		Therefore,			the	jet	as-
sembly is built into the pump.
Air Volume	Control
The air volume	control		(AVC)	maintains		the	cushion		of	air	in
Standard tanks.
