Priming the Pump
The pump housing must be filled with water before starting the pump. This must be done after the
pump is installed and all pipes connected, or may be necessary if the pump has not been run for a
long time.
1. Unscrew the priming plug on top of pump
housing next to inlet.
2. Fill the pump housing with clean water.
3. Replace the plugand tighten it.
Note:
A foot valve on the inlet connection is critical to
help prevent the pump from losing prime.
Installation
The Pump uses 1" NPT piping (sold separately). Purchase the necessary length of pipe, including any
needed fittings and bends. Mount the Pump as close to the source of water as possible and within the
range of the rated Suction Lift. The connections must be airtight. Wrap all threaded connections with
PTFE tape (sold separately).
1.
Connect a bucket full of at least 3 gallons of water to one side of the Y-fitting using a hose, as
shown above. (If available, a continuous water supply,such as a spigot, may be used instead.)
The bucket must be positioned higher than
the pump’s outlet.
2.
Close the valve on the outlet side of the Y-fitting, and open the valve on the priming side of the Y-
fitting.
3.
Remove the Priming Plug and wait until
Water starts coming out of the Priming Plug.
Replace the Priming Plug and tighten
securely.
4.
To start the pump:
a)
Open the valve on the outlet
side of the Y-fitting.
b)
Make sure your hands are dry.
c)
Plug in the pump.
d)
Close the valve on the priming
