PUMP INSTALLATION INSTRUCTIONS
General Information
Because of their ability to process water moderately loaded with
suspended solid particles (or solids), the Waterfall and Filter Pumps
are ideal for use with filtration systems and for creating waterfalls
and watercourses. The pumps are designed to transport suspended
solids to suitable external filter systems (including pressurized fil-
ters) which then trap any debris that could potentially pollute pond
water, effectively filtering the pond. The pumps are not suitable for
supplying water to fountainheads, because the fountainhead jets
could easily become clogged by solids processed by the pumps.
The pump motor sits inside a uniquely-shaped cage that is
designed to allow the passage of solids up to a determined size
only (from 6 mm to 8 mm depending on the model), as bigger
solids may clog and damage the pump. 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 8 inches or 20
cm. 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)
Check that the information on the
nameplate (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.
Installation:
WARNING: Do not plug in the pump before it is correctly and
fully installed.
1) Connect a flexible hose (not included) to the "Click-Fit" coupling
provided. If using a Universal "Click-Fit" coupling (PT-640), cut
the coupling at the required size by using a small hack saw in
order to allow the hose to fit properly and to achieve the best
water flow
2) Insert the coupling, complete with hose attached, onto the outlet
of the pump
3) Place the pump in the pond ensuring that 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 base.
4) Connect the other end of the hose to a filter or waterfall (not
included) according to your requirements
Opening and Closing the Pump Cage
The upper and lower halves of the
pump cage are fastened together by
pivot pin fasteners. Using a standard
flat screwdriver (5 mm to 8 mm), do
the following:
To open the pump cage: Gently turn
the fastener counterclockwise by 1/4
to release the pin.
To close the pump cage: Gently
press on the fastener and turn clock-
wise by 1/4 to lock the pin.
Pump Operation
Once the pump is fully installed, it can be started by inserting the
plug in the electrical receptacle/socket.
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.
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 maintenance procedure below)
• 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 opera-
tion, are present
• 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 big-
ger solid particles (or solids) that could potentially clog the pump
motor. It is therefore normal that these solids progressively accumu-
late 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, 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).
Cleaning the pump motor impeller, impeller
well, and impeller cover
CAUTION: The pump motor includes a high quality ceramic
shaft that provides long-lasting, reliable performance when
(see Fig. 6)
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 frac-
tures, which may cause the shaft to snap while in operation.
Take the pump out of the pond, unlock the pivot pin 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:
