4.
Be sure to inspect the clips that hold the (3) EZ Fittings together, look for wear or stretching of the
clips.
To Clean an Ultra/High Temperature Pump
Note:
1.
The Ultra 4.0 and 4.5 uses non-stick finishes on the float and discharge tube. To protect these finishes,
never use any type of abrasive pad, wire brush, steel wool or sandpaper to clean these two
components.
2.
The Ultra 4.0 and 4.5 uses non-stick finishes on the float and discharge tube. To protect these finishes
never used any high acidic cleaning agent (i.e. vinegar)
3.
To aid in cleaning a pressure washer may be used at a max pressure of 40 psi (2.76 bar)
Caution:
•
Wear chemically resistant rubber gloves, boots, and coveralls when handling the AutoPump and fluid discharge hose
to avoid skin contact with the fluid being removed.
•
Wear safety goggles when working with the AutoPump System to protect eyes from any splashing or pressure
release.
Removing the Pump's Casing
Disconnect the air supply, air exhaust, and fluid discharge lines from the pump.
1.
Remove the bolt at the bottom of the pump which holds the inlet screen in place (bottom loading pumps only).
2.
Remove the three bolts at the bottom of the pump which hold the inlet in place.
3.
Remove the inlet from the pump's casing by pulling it out.
4.
Twist and slide the casing down off the pump's frame.
5.
Cleaning the Pump Interior
•
The inner workings of the pump should now be exposed for inspection and cleaning.
Gently brush off built-up solids from the float, discharge tube, pump casing and control rod.
1.
The bottom "spider" casting should be removed by unthreading it from the discharge tube.
2.
Visually inspect the discharge tube for scale build-up or debris. Also, do the same with the float that slides up
3.
and down on the discharge tube.
Should there be scale deposits on either the discharge tube or float, remove the float from the discharge tube
4.
as Follows: Remove the small steel hairpin from the bottom spring cup. Removing the hairpin
and spring cup will allow you to remove the spring, sliding stop and float from the discharge tube.
The discharge tube and head can now be cleaned using a damp cloth. To aid in cleaning, use a gentle soap
5.
solution (i.e. Dish Soap) through the pump to remove free product particles.
Both the internal and external surfaces of the float can be cleaned using a damp cloth. To aid in cleaning, use a
6.
gentle soap solution (i.e. Dish Soap) through the pump to remove free product particles. The float end plates
can be removed to ease cleaning.
The white plastic control rod is the next component to be cleaned. The control rod is the item that fits
7.
through the smaller hole in the float plate and is adjacent to the discharge tube in the assembled pump.
To clean the control rod, use an abrasive pad or a razor or utility knife (not sandpaper).
The final component to be cleaned is the outer casing. The fastest and most effective way to clean out
8.
the inside surface of the pump casing is to use a three-stone honing tool. The technique is to move the hone
in and out a half dozen times or so, through each end of the casing. The time for the casing cleaning should
take
no longer than 5 minutes with this method.
