Operation And Maintenance - AquaScape Ultra 400 Instructions

Operation and Maintenance

• Filter Screen Cleaning – We recommend inspecting
your pump on a regular basis to make sure it is functioning
properly. Always disconnect the power before performing
maintenance on the pump. If you notice the water fl ow
rate is diminished, it may be due to the fi lter screen or
sponge becoming clogged with debris. In many cases
the fi lter screen can be cleaned by reaching into the water
and manually removing any debris from the fi lter screen
by hand. If there is a lot of debris and/or the debris is
diffi cult to clean, you may need to remove the pump from
the pond or basin for a more thorough cleaning. A garden
hose can be used to spray off any debris stuck on the fi lter
screen. Be sure to re-attach the fi lter screen and pre-fi lter
sponge, before lowering the pump back into the water.

• Connect the pump to an
outlet that is protected
by a ground fault circuit
interrupter (GFCI). Once
the pump is running and
water is circulating, check
for leaks where the external
connections are made.
• Filter Screens – The
outer screen is designed
to pop off when it is gently
pulled from either side. Do
not remove while operating
the pump. Operating the
pump without the front
cover or pre-fi lter sponge
can allow large debris to
enter the pump, causing
the pump to fail, thus
voiding the warranty.

• The pre-fi lter sponge is designed to protect the pump from
fi ne particles, such as sand or other pond debris that could
clog or damage the interior of the pump. Clean the fi lter
sponge using a bucket of pond water or rinse clean using
a garden hose.
• Internal Pump Cleaning – If you have thoroughly
cleaned the fi lter screen and still have diminished fl ow
rates, you may need to clean the interior of the pump.
Remove the water chamber cover by rotating it counter-
clockwise a 1/4 turn and pulling outward. This will expose
the impeller assembly for closer inspection. Carefully
remove the impeller from the pump, pulling outward until
the impeller releases from the body of the pump. Be
careful not to lose the two plastic bearing washers on
either end of the impeller or the centering bushings that
center the ceramic impeller shaft on both ends.
• If your rotor assembly impeller and internal pump body
have excessive scale build-up, clean with a mild acid,
such as white vinegar or non-abrasive calcium, lime and
rust remover product. Use a sponge or soft-bristled brush
that won't scratch or damage the impeller or pump body.
Removing scale build-up will allow your pump to run like
new again.
