Sump Cleaner

9

A.  THE SUCTION/DISCHARGE lever must  
 

be turned its full quarter turn to the vertical  

(DISCHARGE) position in order to close a  

limit switch beneath the lever (FIGURE 5).  

This limit switch bypasses the float switch  

needed to prevent overfilling during the  

suction operation, but is not required for  

discharge operation. The engine won’t start  

in the discharge mode if sump cleaner tank  

is full and the limit switch is not closed.

B.  Be sure the suction inlet ball valve is fully  
 

closed before operating in the discharge mode. 

C. 

IMpORTANT!

 Be sure the suction inlet ball  

valve is fully closed or fully open, depending  

on the desired operation (closed-discharge,  

open-suction). Failure to do so will allow  

particulate to enter the valve seat and  

seize the valve.

8.  When fluid stops passing through the hose,  

release pressure by shifting the SUCTION/
DISCHARGE lever to the horizontal (SUCTION) 
position. This must be done before opening the 
inlet ball valve or removing tank lid, cleanout door 
or drain plug. The engine will momentarily “SPEED 
UP” and then “SLOW DOWN” and begin to 
“labor”. Once the engine has begun to labor, the 
engine may be switched OFF. Open the ball valve 
and turn OFF the gas bottle valve.

9.  The cleaner will discharge all but about an inch  

of fluid in the bottom of the compartment. This is 
unimportant if the compartment is used for one 
type of coolant only. If different coolants are 
involved, remove the compartment’s drain plug  
to empty it completely. Replace drain plug after 
emptying.

10. To empty the filter basket

:

A.  Remove tower lid.

B.  Attach lifting device to basket rings.  

CAuTION:  

All components used to lift basket  

(steel cable, hooks, crane, etc.) must have a  

minimum capacity of 1000 pounds.

C.  To avoid the basket binding in the tower  

during removal, position the lifting power  

source (e.g. crane) directly over the center  

of the basket.

D.  Hoist the basket. Keep hands and fingers  

clear. If the basket is binding and unable to lift  

freely, return (lower) the basket to the sump  

cleaner tower. Reposition the lifting device so  

that the basket exits the center of the tower.

 E. 

DO NOT TOuCH BASKET DuRING  

  REMOVAl.

F.  Position the basket over the waste receptacle.

G.  Standing clear, open the basket trapdoor by  

pulling the locking pin cable.

H.  Once the basket is empty, carefully close the  

trapdoor and slide the locking pin into place.

I.  Check the filter sleeve. If it is badly soiled  

or clogged, turn it inside out and wash it  

in a suitable cleaner. Replace filter when  

necessary. (Refer to the MAINTENANCE  

section of this manual.)

J.  Inspect the basket hoisting rings for signs  

of rust. Replace the basket with a new one  

if the rings are heavily corroded.

K.  Keeping hands and fingers from under the  

basket lip, reseat the basket in the tank and  

clamp down the tank lid.
