CleAninG the PuMP CAGe
The main purpose of the Pump Cage is to keep the pump free of big-
ger solid particles (or solids) that could potentially clog the pump mo-
tor. 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, as evidenced by less water
flow to the filter or waterfall. 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.
• Remove the pump cage from the pond (never lift or hold the pump
by its power cord), unlock the pivot pin fasteners (Fig. 6) 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 Closing the Pump Cage).

(Fig. 7)
CAUTION: 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.
Take the pump out of the pond, unlock the pivot pin (Fig. 6) fasteners
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:
Max-Flo 600/2200 (Fig. 1 + 1A)
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. 1A).
4. Clean all components in clean water only, using a small,
nonabrasive 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 Closing the
Pump Cage).
Max-FLo 960/4000 (Fig. 2)
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,
nonabrasive 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 Closing the
Pump Cage).
Max-Flo 1350/5000 (Fig. 3)
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 housing.
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 Closing the Pump Cage),
by first placing the impeller assembly and then the Seal Ring in
their proper housing.Ensure that the impeller bearing, bushing and
O-Ring are correctly placed at the bottom of the impeller well.
Max-Flo 2000/7600, 2400/9000, 2900/11000, and 4280//16500
(Fig. 3)
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. Clean all components in clean water only, using a small,
nonabrasive 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 Closing the Pump
Cage), ensuring that the impeller bearing, bushing and O-Ring are
correctly placed at the bottom of the impeller well.

For Max-Flo 1350/5000, 2000/7600, 2400/9000, 2900/11000, and
4280/16500 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. 3 & Closing the Pump Cage).

(Fig. 8)
Place the pump inside the bottom half of the cage. Ensure that the
pump is placed in the same direction as indicated on the pictogram
on the inside bottom of the pump cage (A). Ensure that the electrical
cord is properly seated inside the recess located on the bottom half
of the cage.
Close the cage completely, ensuring that both halves are fully aligned.
Lock the pivot pin fasteners as explained in section Opening and
Closing the Pump Cage (D).
Ensure that the pump cage is securely locked and the electrical cord
is seated properly in position before lifting or operating the pump (G).

1. Unplug and remove the pump from the pond.
2. Gently scrub off any dirt and debris with a soft nylon brush.
3. Open the cage by unlocking the pivot pin fasteners and remove the
pump.
4. Thoroughly clean the pump and cage as per instructions in
this manual.
5. In addition, soak the impeller shaft and impeller well in white
vinegar for 24 hours, then rinse off with water. This procedure
will remove calcium 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.
6. Lubricate all seals with Laguna Silicone Lube
(sold separately/ PT595).
7. Store indoors for best results. Do not store the pump in below
freezing temperatures.
8. 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.
