• 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.

• 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.
