Sump Cleaner

11

The tank’s maximum capacity is, at most, 10% 
above the rated capacity. A float switch in the 
tank and wired into the engine ignition circuit will 
shut down the engine if overfilling starts to occur. 
If this happens, place the IGNITION switch in 
the OFF position, and close the gas bottle valve.  
Follow instructions for the discharge operation in 
Paragraph 10. 

6.  To return filtered chip-free coolant to the sump, 

or wash down the machine, or discharge dirty 

coolant into your recycling or disposal system

, 

close the suction inlet ball valve V1, attach the  
1-1/2" hose to the discharge port. Move the 
4-way valve control lever to the vertical 
(DISCHARGE) position. Open the gas bottle valve 
and press the electric primer button for at least 
two seconds. Turn the IGNITION KEY SWITCH 
ON. Depress the discharge hose nozzle valve. 
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 V1 is fully  
 

closed before operating in the discharge mode. 

C. 

IMpORTANT!

 Be sure the suction inlet ball  

valve V1 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. 

D.  As soon as 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. 

The sump 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.

7.   To fill the clean side with clean fluid: 

Activate 

the float switch for the compartment selected 
by setting the TANK OVERFILL PROTECTION 
SELECTOR SWITCH to the appropriate position 
(FIGURE II-C). This float switch prevents over-
filling of the compartment and pump damage 
during the suction cycle by turning off the engine’s 
ignition circuit at a predetermined liquid level. 
A. Install the 1-1/2" hose onto the clean side  
 

inlet port, remove the discharge nozzle and  

install that end of the hose to a recycling  

system or a clean tank

B. Place the SUCTION/DISCHARGE lever in  
 

the horizontal (SUCTION) position. Open the  

LP Gas bottle valve. Open the suction inlet  

ball  valve. Place choke in “ON” position.  

Turn ignition key to the “START” position  

while moving choke to the “OFF” position.  

Release key when the engine starts and  

move choke to the “OFF” position.
