FIGURE 1
Used as a Submersible Pump
•Submerse the pump completely in your pond to make the pump body
fill with water.
•A minimum water level of approx. 6 in. is required for submersible use
in order to prevent the pump from taking in air. (see fig.1)
•Place the fountain pump above the mud in the pond to prevent the
filter becoming prematurely clogged.
•The pump is designed to accommodate internal threads as well as
external threads through the socket (fountain jets, nozzles, water
height regulators, standpipes, etc.).
•Running in conjunction with fountain jets, the pump should be
stationed firmly and horizontally.
•The pump can be switched on by simply plugging it in and switched
off by un-plugging it.
•The water temperature should not exceed 95°F (35°C) and do not let
the pump freeze in the wintertime.
•This pump is not intended for use by persons, (including children) with
reduced physical sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or
instruction concerning use of the pump by a person responsible for
their safety.
•Children should be supervised to ensure that they do not play with the
pump.
FIGURES 2 & 3
Proper Care and Maintenance
•Always follow the safety instructions. Make sure that the pump is
unplugged.
•If the pump is housed in a skimmer make sure the screens and
filters in the skimmer are kept clean and free of debris. This will
allow water to flow unrestricted into the pump chamber. Every
water feature is different; learn how frequently your skimmer
needs to be cleaned to allow unrestricted water flow. Pumps run
dry and damaged due to restricted water flow in a clogged
skimmer are not covered under the terms of the warranty.
•If the pump is operated directly in the water feature make sure the
pump intake screen is kept clean and free of debris. Pumps that
run dry and damaged due to restricted water flow are not covered
under the terms of the warranty.

•In hard water conditions, it is recommended that you periodically
remove the pump from the water feature and operate it for up to
36 hours in a solution of CLR (Calcium Lime Rust Remover) and
water. Rinse thoroughly before re-installing the pump in the water
feature.
Disassembling the Pump
•Follow these step by step instructions if the pump requires more
intensive cleaning.
•Press the intake cover (1) together laterally and take it from the
pump housing.
•Loosen the 4 outer screws (9).
•Rotate the pump housing (6) ¼ turn counter-clockwise. Unclip it
from the motor housing (4).
•Remove the rotor (8) from the motor housing (4).
•Clean all parts using water and a soft sponge. In hard water
conditions a mixture of CLR and water bath is recommended.
Assembling the Pump
•Place the rotor (8) in motor housing (4) with caution.
•Make sure the rotor is assembled correctly and will turn freely and
check the position of the sealing ring (7) on the pump housing (6).
•Put the pump housing (6) on and turn clockwise ¼ turn. Tighten
the 4 screws (9) uniformly.

CAUTION
These pumps are not for use in swimming pools! Swimming in water being
circulated or oxygenated by these pumps poses a severe, imminent and
potentially fatal risk to human health.
These pumps should be installed per your local electrical code. Please contact
an electrician. For all technical data, please refer to the content stated on the
rating label of the pump.
Do not operate these pumps without water. If the pump runs, for any length of
time, in a dry condition without water it will damage the pump and void the
warranty.
Safety Instructions
•Read and observe all the instructions supplied with the pump and on
the pump.
•Make sure that your outlet voltage corresponds to those stated on the
rating label of the pump(s).
•Make sure the pump is securely installed before operating it.
•The electrical connection should be in a water-proof area and should
be at least 6 feet away from the edge of the pond. (see fig. 1)
•Keep the electrical connections dry! Droop the electrical cord below
the electrical outlet to form a “Drip Loop”. This will prevent water from
running down the cord into the electrical outlet
•Always unplug the pump when not in use, before putting on or taking
off parts, before cleaning the pump and before doing any work for the
fountain or pond.
•The pump must not be used when people are working in water. Please
disconnect the pump first.
•Do not operate any appliance with a damaged cord or plug, or in
abnormal state. The supply cord of the pump cannot be replaced.
•If the cord is damaged the pump should be scrapped.
•Do not cut the plug end off the cord for any reason. Cutting the
cord voids the warranty and may create an electrical hazard.
•For safety reasons, any repair work should be done only by the
manufacturer of the products or the authorized service facility or
discard it
•Never hang or transport the pump by means of pulling the power cord!
•Close supervision is necessary when the pump is used by or near
children.
•If you want to disconnect the pump, you can pull out the plug and the
plug must be placed where you can access it.
•Never use any accessories which are not recommended by the pump
manufacturer. It may result in fire, electric shock, personal injury
and/or voided warranty.
•The pump is to be supplied through a Ground Fault Circuit Interrupter
(GFCI) with a rated residual operating current not exceeding 30mA.
•To protect against the risk of electrical shock, do not immerse the plug-
in water or other liquid.
