• The outer screen is designed to pop off when it is gently
pulled from either side.
• 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 using a sponge or soft-bristled brush
that won’t scratch. Removing scale build-up will allow your
pump to run like new again.
• The pre-filter sponge is designed to protect the pump
from fine particles, such as sand or other pond debris, that
could clog or damage the interior of the pump. Clean the
filter sponge using a bucket of pond water or rinse off with
a garden hose.
Replacing the Impeller
• The impeller assembly is the only moving part on the
Ultra
™
Pump and will experience wear and tear. If
you’ve cleaned the pump, as described above, and still
experience poor pump performance, it is most likely time
to replace the impeller. Replacing the impeller is extremely
easy. Replacement Impeller Kits are available through your
local Aquascape
®
dealer.
1a. Note the orientation of parts in the photo below.
The replacement impeller kits include all parts shown.
Make sure to remove all of the original parts from
the inside of the pump before installing the replacement
impeller kit.

Internal Pump Cleaning –
If you have thoroughly
cleaned the filter screen and sponge on the pump and still
have diminished flow rates, you will need to remove the
water cover chamber by rotating it about ¼ turn counter
clockwise past the tabs and pulling it off. This will expose
the impeller assembly to allow for closer inspection.
Carefully remove the impeller from the pump, being 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.

there is a lot of debris and/or the debris is difficult 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 filter screen or sponge.
Be sure to replace both the screen and sponge and make
sure they are firmly attached to the pump body, before
lowering the pump back into the water.
