equipment. The pump chamber of Laguna's Skimmer Filter is sufficiently large
enough to hold two pumps if desired. Simply run the tubing through the
other side opening of the Skimmer Filter and the electrical cord through the
channel located at the back of the unit.
TIP: Ensure that the length of tubing that you will connect to the pump
output is long enough to perform the desired task, whether to circulate
water to a connecting Filter Falls unit, or back into the pond, or to another
piece of pond equipment.
Note: Use Laguna Silicone Lubricant to make hosing connections
easier and hose clamps to secure all hose output connections.
Pump Maintenance
WARNING: Always unplug or disconnect all appliances in the
pond from the electrical supply before installing, repairing,
maintaining or handling the equipment in the water.
Impeller Maintenance
NOTE: The pump motor includes a high quality ceramic shaft that
provides long-lasting, reliable performance when properly
maintained. However, extreme care should be taken when
handling the shaft during maintenance. Avoid dropping or
pressing too hard on it to avoid breakage or hairline fractures,
which may cause the shaft to snap while in operation.

1) Using a Phillips (cross-headed) screwdriver, unscrew the four screws on
the impeller cover (4) and remove the cover.
2) Using a flathead screwdriver, carefully lift out the impeller assembly (3).
3) Clean all components in clean water only, using a small, non-abrasive
brush, if necessary. DO NOT USE DETERGENTS OR OTHER CHEMICAL
CLEANERS which could damage the pump and pollute the pond.
4) Reassemble all components with care, ensuring that the impeller
bearing, bushing and O-Ring are correctly placed at the bottom of the
impeller well.
Replacing the Bushing and O-Ring
(Replacement pack not included. Part # PT-466).
Though the bushing is made of very resistant material, it is prone to wearing
in certain conditions. For this reason, it is recommended that you replace it
whenever the impeller unit is replaced. Follow the instructions provided
with the replacement parts package. Once you have replaced the Bushing
and O-Ring, reassemble all parts with care.
TROUBLESHOOTING
LOW FLOW FROM PUMP
• Check that strainer is clean
• Check tubing for blockages
• Check that the pump is free of dirt and debris
NO FLOW FROM PUMP
• Check that the power supply is on
• Check that the plug is correctly connected to the electrical
receptacle/socket
• Check tubing for blockages
• Disconnect pump, remove impeller assembly & clean, then reconnect the
pump.
THERMALLY PROTECTED PUMP
To prevent the motor from overheating if the pump accidentally "runs dry"
or if the rotor becomes blocked, the thermal protector will shut the pump
off. To re-set the thermal protector, remove the power source, allow pump to
cool, inspect pump and usage conditions, then re-establish power.

WINTERIZING THE PUMP
1. Unplug and remove the pump from the pond.
2. Gently scrub off any dirt and debris with a soft nylon brush.
3. Thoroughly clean the pump as per instructions in this manual.
4. In addition, soak the impeller shaft and impeller well in white vinegar
for 24 hours, then rinse off with water. This procedure will remove calci-
um and other mineral deposits from the impeller shaft. If these deposits
are not removed they may cause the shaft to bind and break when the
pump is started again.
5. Lubricate all seals with Laguna Silicone Lube (sold separately/PT-595)
6. Store indoors for best results. Do not store the pump in below-freezing
temperatures.
7. When re-opening your pond or water feature in the spring, submerge
the pump in the pond for 1 hour prior to starting the pump.
