PUMP INSTALLATION
INSTRUCTIONS
GenerAl inForMAtion
PowerJet pumps are designed to generate powerful water circulation
that is essential for the creation of fountains and waterfalls. Besides
being pleasant to see, water flow contributes to the oxygenation of
pond water, which is beneficial to pond fish and plants. The pump is
designed to circulate clear water only and is not a pond filter.
The pump motor sits inside a uniquely-shaped cage that is designed
to block out any solids that could potentially clog the pump and
fountain jets. This unique blocking feature ensures an extended
period of reliable operation. The pump must never be used without
its cage.
For improved operation, place the pump in the deepest part of the
pond. At minimum, it must be placed at a depth of approximately
8 inches or 20 cm. In order to prevent the pump from sucking dirt
directly from the pond bottom, we recommend that you install it on an
elevated surface that is flat and level. If necessary, you can secure the
pump to a fixed base by using the keyhole-shaped slots, located at
the bottom of the cage, which are shaped to allow the fast engaging/
disengaging of the pump from the base. (Fig. 5) Use the template (Fig.
5A) to determine the exact position of the screws on the fixed base.
Note that the base must be elevated, solid, and secure.
Check that the information on the rating label (which is located on
the pump) corresponds to the power supply. The electrical installation
and wiring must comply with the safety standards in your area. If
unsure, ask a qualified electrician to do the wiring. The electrical cord
must be protected against any objects that may potentially damage
it. The electrical receptacle/socket must be located in a dry, protected
and easily accessible place.
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.
IMPORTANT: To achieve the best pump operation, always use
the largest bore hose possible. Avoid sharp bends in the hosing;
gradual curves are preferred.

WARNING:
Do not plug in the pump before it is correctly and
fully installed.
1. Insert the Telescopic Riser Stem (9) into the relevant seat of
the diverter (8).
2. Insert the Fountain Jet (11 or 12) on the top of the Telescopic
Riser Stem (9).
3. Insert the Diverter (8) complete with the Telescopic Riser Stem (9)
and Fountain Jet (11 or 12) onto the pump output, ensuring that
the "Click-Fit" coupling clicks into place.
4. If installing an underwater filter (sold separately), see the section
Extending pump operation using a PowerFlo Underwater Filler.
If using the backwash feature to periodically rinse the pump cage,
see the section Pump Cage Backwash.
5. Place the pump in the pond ensuring that it is completely
immersed in water and securely installed on a solid, level and
elevated platform. If necessary, use the keyhole-shaped slots at
the bottom of the pump to fasten it to a secure level base (this will
ensure the telescopic riser stem remain upright and balanced). Use
extra care when engaging or disengaging the pump.
6. Adjust the height of the Fountain Jet (11 or 12) by moving the
Telescopic Riser Stem (9) up or down.
7. To further increase the height of the Fountain Jets, attach an
optional Extension Tube (sold separately, PT645). Not applicable to
Model 600/2200.
8. To use the additional outlet of the Diverter to transfer water to a
waterfall, a PowerClear UV Sterilizer or other equipment, connect a
flexible hose (not included) to the side outlet of the Diverter using a
Click-Fit coupling. If using a Universal Click-Fit coupling (15), cut it
off at the required size by using a small hack saw in order to allow
the hose to fit properly and to achieve the best pump performance.
9. Water flow to the Fountain Jet or Waterfall Outlet can be adjusted
separately using the two control valves located on the sides of
the Diverter (8).

To reduce the frequency of cleaning the pump and extending pump
operation, you can connect the main pump cage to a Laguna
Underwater Filter (PT505). In addition to prolonging pump operation,
installing a filter also improves the quality of your pond water.
1. Open the pump cage by unlocking the pivot pin fasteners (Fig. 6).
2. The Pump Cage is equipped with a pre-scored section (Fig. 7) that
must be cut out with a suitable cutting tool.
3. Insert a Remote Adapter (sold separately) (10) in the scored
opening at the back of the Pump Cage.
4. Close the cage, ensuring that the two halves are properly aligned
and coupled, and then lock them with the pivot pin fasteners
(Fig. 6) on the unit.
5. Connect the Pump Cage to the filter using flexible hosing (not
included) attached to the Click-Fit hose connector.
IMPORTANT:
During pump operation, the Underwater Filter must
always be completely immersed in water to prevent air from
being sucked into the pump and damaging it. Also ensure that
the Pump Cage is securely locked before lifting and operating
the pump.

The backwash system allows you to connect a garden hose to the
pump in order to partially clean off any dirt and debris resting on
the surface of the pump cage. This feature ensures the temporary
restoration of water flow through the pump and also brings new
water to the pond. Use the Remote Adapter (10) and Garden Hose
Adapter (13) to connect a garden hose to the pump cage. Connect
the other end of the hose to a tap/water faucet. Disconnect the pump
from the main power supply. Run the water through the pump cage
for at least 1 minute. Restore power to the pump. Repeat if necessary.
NOTE: Add a suitable amount of Laguna Water Prep
dechlorinator PT861/PT863/PT864 (sold separately,) when
adding tap water to the pond.

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. NEVER LIFT
THE PUMP BY THE CORD.
To avoid shortening the life of the pump, follow these simple
maintenance procedures:
• Once a week, verify that the pump performance is satisfactory. If
you detect a drop in pump performance (such as a decrease in
water flow from the pump or to the waterfall) first clean the Pump
Cage and the hosing. If the water flow is still not fully restored
to its original performance, clean the Impeller, Impeller Well and
Impeller Cover (See Cleaning).
• The Pump Cage must be cleaned at least once a month.
• When necessary, or at least once a year, clean the pump motor
completely (Impeller, Impeller Well, and Impeller Cover) and check
that no limestone deposits, which could jeopardize pump operation,
are present.
• To keep the pump in good working order, always replace any
worn parts.
• Check the line cord integrity after maintenance.
• 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
bigger solid particles (or solids) that could potentially clog the
pump motor. 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.
• 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 (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).

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.
