Both the 4-inch and dry break inlets seal automatically when
removed from the tank. To flush properly, the inlet must be
open. One way to keep these inlets open is to temporarily
install the tank bung or nipple onto the inlet. Simply remove
the bung or nipple from the tank, unscrew the suction pipe,
and screw or snap it onto the inlet. (Figure 8)
Another option for the 4-inch inlet is to carefully insert a small
wooden dowel into the 4-inch inlet to hold it open. (Figure 9)
1.
Disconnect from power. Remove the pump from the tank
and drain using the instructions above.
2.
As necessary, open the inlet based upon the information
above.
3.
Carefully make grounded connection to GFCI protected,
115-volt power.
4.
Place the pump inlet and nozzle through the holes in the
top of the flush tank. (Figure 10)
5.
Open the nozzle and turn the pump on. Circulate water
through the pump for 10 to 15 minutes. Open and close
the nozzle several times to flush the bypass poppet.
6.
Lift the pump from the water. Allow the pump to run brief-
ly until only air passes through the system. Turn the
pump off.

CAUTION: Do not run the pump any longer than necessary
without flow. “Dry running” can cause overheating and
pump damage.
7.
Drain the hose and nozzle. Wipe entire system with a
clean wet cloth.
Clean Pump
If chemicals dry inside pump, remove the residue before
further use.
1.
Disconnect from power, remove the pump from the tank,
and flush.
2.
Disassemble the pump as outlined in the Repair Section.
3.
Thoroughly clean dried chemical from the interior of the
pump. Take care not to scratch parts.
NOTE: Do not disassemble the manual bypass poppet
assembly or the inlet fitting.
4.
Wash the bypass poppet in warm soapy water. Rotate
the spring and plug on the manual bypass poppet to
make sure they move freely. (Figure 11)
5.
Assemble the pump.
End of Season
If the system will not be used for an extended time, flush and
clean, as necessary. Follow the steps below to prepare for
storage.
In the procedure below, a flush tank is required and the pump
inlet must be held open. Please reference the information on
these topics above in the Flush Pump instructions. This
procedure requires 100% antifreeze in the flush tank instead
of water.
1.
Disconnect from power. Remove the pump from the tank
and drain.
2.
As necessary, open the inlet based upon the information
in the Flush Pump procedures above.
3.
Connect a short length of petroleum compatible flushing
hose to the pump outlet.
To avoid chemical exposure, follow chemical
manufacturer’s instructions for the disposal of con-
taminated water.
