Iron Build-up Cleaning Procedure
After the casing has been removed from the AutoPump please follow the procedure
below:
Note:
The procedure described below can be seen in the Maintenance Video
Tape. This will aid the technicians understanding and ease of properly
disassembling the AutoPump, effectively cleaning components and then
re-assembling the AutoPump.
STEP 1 -
The bottom intake check valve assembly should be removed from the
casing.
(See page 47, and Figure 20 on page 48)
STEP 2 -
Visually inspect both the 1 inch stainless steel fluid discharge pipe for iron
build-up or debris. Also, do the same with the float that rides up and down
on the SS discharge pipe.
STEP 3 -
Should there be iron deposits on either or both the discharge pipe or float,
then remove the float from the SS fluid discharge pipe as follows:
- Remove the control rod guide.
(See Figure 22 and Figure 23)
- Remove the small SS pin from the bottom spring cup “Stop”. The
Stop is the small white part located just below the Spring identified
on
Figure 22 and Figure 23
. The pin and Stop removal will allow
you to remove the spring and float from the SS discharge pipe.
STEP 4 -
The 1/2 inch stainless steel fluid discharge pipe can now be cleaned
using either a Scotch Brite pad, a wire brush or finally a wire wheel on
either a drill or a grinding machine. After removing the iron debris, it is
recommended the pipe be water rinsed.
STEP 5 -
Both the internal and external surfaces of the float will generally require
cleaning. The material choices include a Scotch Brite pad, and a light
grade 150 sandpaper.
The float has a metal plate on each end. If these plates are removed to
ease cleaning, they should be replaced on the same float end from which
they came. That is, the plates should maintain their original top and
bottom positions.
