Page 4: Installation
Installation Before you install your pump Dirt and Scale Plug Pump and Pipes! NOTICE: Well must not be more than 20’ depth to water. 1. Long runs and many fittings increase friction and reduce flow. Locate pump as close to well as possible: use as few elbows and fittings as possible. 2. Be sure well is clear of sand. Sand will plug the pump and void the warranty. 3. Protect pump and all piping from freezing. Freezing will split pipe, Use New Pipe for Best Results. - Page 5 Installation Cased Well Installation Priming plug 1.

Page 8: Operation
Operation Priming The Pump NOTICE: The term ‘priming’ refers to the process of pumping all the air out of the system, filling the pump and suction piping with water, and beginning to move water through the pump and out into the system. A ‘self- priming’ pump generally will repeat this process without attention once the pump and system are full of water. If the water drains out of the pump (back into the well, for example), then the whole priming process must be repeated before operating the pump again. -
