• internal Pump Cleaning - if you have thoroughly cleaned
the filter cage screens and still have diminished flow rates,
then you will need to remove the pump from the circular
base to inspect and clean the impeller rotor assembly.
• Pull the cage release
tabs outward to
unlock the upper
pump cage.
• While holding the
pump securely,
rotate the water
chamber cover
counter-clockwise so
it can be removed
from the pump.
• With the impeller assembly now exposed, it can be
removed from the pump by pulling outward on the impeller
blades. IMPORTANT: Take care not to lose the outer impeller
shaft centering bushing. This bushing seats inside the water
chamber cover and sometimes it remains in the cover when
the cover is removed. If, however, this bushing stays on the
impeller shaft, simply slide it off the shaft and set it aside
or replace it in the water chamber cover so the impeller
assembly can be removed from the shaft.
• With the cage tabs
released the filter
cage can be lifted
to expose the pump
• The procedure to remove the pump from its mount varies
depending on the pump model. the 600 and 1300 are
easily removed by depressing the tab on the mounting
bracket and sliding the pump forward towards the water
chamber cover.
• For the Model
2000, remove
the two screws
securing the pump
holding brackets
to allow the pump
to be lifted from
the circular base.
please make a note
of the pump bracket
orientation prior to removing the screws so the brackets can
be replaced onto the pump in the same orientation. the
power cord can be left in the strain relief, if desired, in order
to simplify reassembly.

• If your rotor assembly impeller and internal pump body have
excessive scale build-up, clean with a mild acid, such as
white vinegar or any calcium/lime remover and a kitchen
sponge or soft bristled brush that won’t scratch the stainless
steel. this will remove the scale build up and allow the
pump impeller to spin like new again.
