Assembly / Installation / Operation / Maintenance

PUMP ASSEMBLY

Models 390.121800 and 390.122600 are pre-assem-
bled. For all other models, refer to Figures 1 thru 3 for
pump assembly as required by your model. Connections
are either slip fit or threaded, no epoxy or thread com-
pound is required.

INSTALLATION

1. Install pump on a hard level surface. Keep pump
elevated from pond bottom to reduce maintenance.
Position pump so that fountain jet is just above sur-
face of water.
2. Protect pump power cord from damage. Uncovered
cords should be routinely inspected for damage or
deterioration. DO NOT operate pump if cord is dam-
aged.
3. Adjust diverter valve to control fountain spray height,
DO NOT restrict pump suction to accomplish this.
Refer to performance chart (Page 4) for maximum
fountain spray height for each individual model.
(When used as a fountain only).
4. Pumps connected to pond filters must be adjusted at
the diverter valve to provide adequate flow to the fil-
ter. Refer to filter instruction manual to determine
flow requirement of individual filter units.
5. Use hose clamps to secure tubing connected to
diverter valve fitting, pond filter or ornamental
statuary.
OPERATION/MAINTENANCE
1. Pump is a submersible type and must be under water
at all times for proper operation and cooling.
Never run pump dry!
2. Clean inlet filter regularly. A clogged inlet filter will
reduce flow which can damage the pump.
NOTICE: Most pumps are equipped with a thermal pro-
tector that will shut pump off if operating temperature
becomes too high, possibly due to restricted flow, or a
clogged impeller. Pump will restart when the motor has
cooled sufficiently.
Periodically check to see that impeller rotation is not
being hampered by any debris and to clean internal
components.
Disassembly/Cleaning
Refer to exploded views, Pages 5 and 6, to match disas-
sembly procedure with the pump you have purchased.
Hazardous voltage. Disconnect power
before working on pump.
Models 390.121800 and 390.122600
