total insulation against water damage and electrical shock. The
motor is extremely compact, energy efficient and maintenance-free,
while at the same time producing a powerful continuous output flow.
Choosing the right output for the application
Laguna Utility pumps can be used in a wide variety of applications,
and their wide range of output flows at various heights will accom-
modate almost every circumstance. What is most important is to
define the needs of the application and ensure the pump will be ade-
quate to the job. The factors that influence pump capacity include
Head Height, hose and fitting resistance:
Head height: Vertical distance between water surface and water dis-
charge.
Hose Resistance: For every ten feet (3 m) of hose, add one foot (30
cm) to the head height.
Fitting Resistance: For every elbow connector, add one foot (30 cm)
to the head height.
Determine the head height first, the vertical distance from water sur-
face to water outlet. To this, add the amount of hose needed to trans-
port the water from pump exhaust to the water outlet. When pipe
fittings are used to go around corners, the resistance to water flow
o
created by a 90 elbow is equivalent to adding one foot (30 cm) per
unit.
If the installation requires a 90 cm (3 ft) lift from surface to output,
requires 3 m (10 ft) of hose and one elbow, then the actual head is
150 cm (5 ft).
INSTALLATION
Caution: Disconnect the plug of this and any other submerged
appliance before placing hands in water.
Important: Always use the largest bore hose possible.
Avoid sharp bends in the hose, gentle curves present less resistance
and water flow loss.

ATTACH INPUT/OUTPUT HOSES:
The Laguna Utility Pump 1: accepts a hose on the output only.
The Laguna Utility Pumps 2 and 3: smooth hose adapters on both
input and output sides receive the hose directly. If required, a hose
clamp (optional) can be used to clamp the hose on the adapter in a
more permanent fashion. For ornamental accessories, use the
Stepdown Output Hose Adapter (1/2", 13 mm)
Laguna Utility Pumps 4, 5, 6 and 7: each employs the exclusive
Click~Fit coupling for both input and output. The fitting is barbed to
ensure a tight fit and superb connection between hose and connec-
tor. If a hose clamp is desired, the barbed configuration ensures
there will be no loosening during the pump's operation. Once
installed there is no need to remove the hose from the fitting. The
Click~Fit coupling snaps on and off with the press of a thumb to
make maintenance simple and quick. For permanent connections
directly to the pump, there are input and output stems built into the
Motor Cover that will accept a hose clamp.
Flow Control
The only unit with an adjustable flow control is the Laguna Utility
Pump 1. Adjust the slide bar on the Motor Cover to increase or decrease
flow.
Location
The pump should be placed on a flat, level surface.
Laguna Utility Pump 1: Because of its size Laguna 1 is not equipped
with a base to attach the unit to its surroundings. There are three
suction cups to secure it to the bottom. Ensure the area is clear of
debris that might be sucked into the input and clog the impeller.
Laguna Utility Pumps 2 and 3: These models are equipped with a
removable base. It can be used with suction cups (included) to
secure to the bottom. Alternately, four holes in the base unit allow
screws to position the pump in the correct place. Once the base is
positioned with either suction cups or screws, place the pump over
the base, output facing in the same direction as the arrow engraved
on the base. Press down and forward to lock the pump to the base.
