7.1.4 Impeller
In cases where the performance of the pump decreases, the
condition of the impeller should be checked for wear and tear.
Before placing the Aqualift F Pumpstation in service or if the
Aqualift has not been in service for an extended period of
time, the impeller should be turned by hand to make sure
that it rotates smoothly.
7.2 Control unit
• The batteries in the control unit should be inspected at least
once per year and replaced if necessary. Replacement bat-
teries should be identical to the originals. Dispose of old bat-
teries properly
• The motor protection switch is considered a wear and tear
part and should be checked every year and replaced if ne-
cessary. Please replace with the identical switch (see Chap-
ter 9) and dispose of the old switch properly
• Please make sure the see-thru cover of the control unit is
properly closed and tightened.
• Repairs of the control unit should be undertaken by the ma-
nufacturer only.
7.3 Pump Disassembly
Disassembly of an Aqualift pump may be undertaken only by
a qualified licensed KESSEL customer service partner.
7.4 Non-Return flap information
In the case that the Aqualift F system needs to be serviced,
the non-return flaps can be manually opened to allow any wa-
stewater in the outlet system to drain back into the Aqualift F
storage tank before a pump or the entire tank is removed. If
this is required use a Size 8 wrench to move the red lever
from to the right (from the horizontal to the vertical position).
This will manually open the flap and drain any wastewater
back into the storage tank (see Illustration 2). Be sure to
move the red lever back to the original (vertical) position
when complete (see Illustration 3).
The bolts on the upper and lower portion of the non-return
Notice:
flap assembly can be removed in order to access the non-
return flaps. Prior to doing this be sure to drain all waste-
water from the outlet pressure piping.
