Operation
TO PREVENT ELECTRIC
SHOCK AND DEATH:
Make sure that the Connection Box Cover
(42) is properly closed and sealed before
priming or operation.
Note: A foot valve on the inlet connection is critical to help
prevent the pump from losing prime.
Note: Check that the water source and piping are clear of
sand, dirt and debris.
1.
Pump
Bucket
full of
clean
water
Priming Hose
Outlet Pipe
Inlet Pipe
Foot
Valve
Y-tting
(with one valve
for each outlet)
Connect a bucket full of at least 3 gallons of water
to one side of the Y-tting 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-tting,
and open the valve on the priming side of the
Y-tting.
3. Remove the Priming Plug (23) 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 outlet side of the Y-tting.
b. Make sure your hands are dry.
c. Plug in the pump.
d. Close the valve on the priming side of the Y-tting.
CAUTION: Do not run the Pump Dry! Turn off the
Pump IMMEDIATELY if water stops coming out
the Outlet.
5. If you operate the Pump and no water comes out,
shut the Pump off IMMEDIATELY. Check the pipes
for air-tightness. Check also that the bottom of the
Inlet pipe is underneath the surface of the water
and a foot valve is properly installed.
6. After the pump is running properly, the priming
hose and bucket can be disconnected.
Storage
1. If you will not be using the Pump for an extended
period of time, drain the Pump Body (22). First
disconnect both the suction and outlet lines, then
tip the pump so that all the water is drained from
the pump cavity.
2. If the Pump sits idle for a period of 5 days or
more, it should be unplugged and rotated with
a screwdriver through the middle hole of the fan
cover through several revolutions to prevent it from
taking a permanent set.
3. If you use the Pump only occasionally, when you
are done pumping, replace the Inlet and Outlet
covers to protect the unit.
