• To keep the pump in good working order, always replace any worn parts
• The pump motor has no user serviceable parts. If the motor or the electrical cord is
damaged, discard the pump
• If you have any doubts, consult your Laguna retailer or call the appropriate
customer service department listed at the back of this manual
Cleaning the Pump Cage
The main purpose of the Pump Cage is to keep the pump free of solid particles (or
solids) that could potentially clog the pump and fountain jet. It is therefore normal that
these solids progressively accumulate on the external surface of the cage and, with the
passing of time, can diminish the performance of the pump. To clean the cage and
restore the pump performance to its original level, proceed with one of the following:
• Without removing the pump from the pond, brush off the debris from the external
surface of the cage using a broom or similar tool. For best results, brush the cage
along the ribs
• If you have set up the backwash system (see Pump Cage Backwash), turn the pump off
and introduce tap water into the pump for at least 1 minute, without removing the
pump from the pond
• Remove the pump cage from the pond, unlock the pivot pin fasteners (Fig. 7) and
remove the upper half of the cage. Clean all components with streaming water
from a garden hose. Reassemble all components with care
Ensure that the pump cage is securely locked and the electrical cord is seated
properly in position before lifting or operating the pump (see Fig. 10 section).
Cleaning the pump motor impeller, impeller
well, and impeller cover
CAUTION: The pump motor includes a high quality ceramic shaft that pro-
vides 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.
Take the pump out of the pond, unlock the pivot pin fasteners (Fig. 7) and remove the
upper half of the cage. Free the pump from the lower half of the cage.
Proceed with the following cleaning instructions as per pump model:
PowerJet 400/1500 and 600/2200 (Fig 1)
1) Remove the motor cover, then remove the impeller cover (4) by twisting and
pulling it off.
2) Remove the impeller assembly (3)
3) If necessary, remove the impeller shaft (3A) using the tool provided (A-17015)
(Fig. 2)
4) 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.
5) Reassemble all components with care (see Fig. 10 section).
PowerJet 900/3500 and 1300/4500 (Fig. 3)
1) Using a Phillips (cross-headed) screwdriver, unscrew the four screws on the
impeller cover (4) and remove it
2) Remove 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 (see Fig. 10 section).
PowerJet 1500/6000 (Fig. 4)
1) Using a Phillips (cross-headed) screwdriver, unscrew the three screws on the
impeller cover (4) and remove it
2) Remove the impeller assembly (3) by grasping the flange. This operation will
cause the Seal Ring (2) to come out of its seat
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 (see Fig. 10 section), by first placing the
impeller assembly and then the Seal Ring on their proper seats. Ensure that the

impeller bearing, bushing and O-Ring are correctly placed at the bottom of the
impeller well.
PowerJet 2000/7500, 2400/9000 and 2900/11000 (Fig. 4)
1) Using a Phillips (cross-headed) screwdriver, unscrew the four screws on the
impeller cover (4) and remove it
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 (see Fig. 10 section), ensuring that the
impeller bearing, bushing and O-Ring are correctly placed at the bottom of the

Replacing the Bushing and O-Ring (Replacement pack not included.
Part # PT-466).
For PowerJet 1500/6000, 2000/7500, 2400/9000 and 2900/11000 only
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 (see Fig. 10 section).
Put the pump back in its original position by laying it in the bottom half of the cage
(Fig 10). Fasten the electrical cord to the bottom half of the cage, ensuring that the
electrical cord is seated properly in position. Close the pump cage by first engag-
ing the upper half of the cage to the lower half in the pre-arranged
seats opposite the cage handle. Then close the two halves together, ensuring
that they are correctly aligned and there are no openings. Finally, lock the two halves
together using the pivot pin fasteners.
Ensure that the pump cage is securely locked and the electrical cord is seated
properly in position before lifting or operating the pump.
