Operation

Before operating this equipment for the first time, 
and periodically thereafter, review the SAFETY 
INFORMATION beginning on page three of  
this manual.

Standard Safety Features

Your Sump Cleaner comes equipped with redundant 
safety features to assure that it operates in the safe 
optimal pressure range. The standard regulator is 
factory set at 7 PSI. This assures that air entering 
your unit to create the pressure needed for  
discharge does not exceed safe levels.

In the event of a failure of the regulator, as a backup, 
the Sump Cleaner also features a standard “safety 
release valve” which is designed to release pressure 
in excess of 8 PSI.  

As part of your regular maintenance program, you 
should examine both the regulator and safety release 
valve to make sure that neither has been damaged 
during use and that both are free from dirt or materials 
which might plug openings or interfere with their 
operation. The regulator should be periodically 
checked to make sure that it is set and operating at  
7 PSI. If either component becomes damaged or is 
not operating as intended, the unit should be taken 
out of service immediately until the parts are repaired 
or replaced.

DO NOT

 eliminate the safety release valve or replace 

it with a release valve rated higher than 15 PSI.

DO NOT

 reset the regulator to a pressure setting 

above 7 PSI.

1.

  Before operating this equipment for the first time, 

and periodically thereafter, review the SAFETY 
INFORMATION included in this manual.

2.  Suction Operation:

A.  Connect the shop’s compressed air supply line  
 

to the sump cleaner’s vacuum generator inlet. 

B.  Open suction inlet valve and vacuum valve. 
C.  Turn on the compressed air to the sump  
 

cleaner. Vacuum coolant, chips and sludge  

from the machine sump. 

D.  When you are done vacuuming coolant, turn  
 

off the compressed air to the sump cleaner. 

E.  The tank’s maximum capacity is, at most,  
 

10% above the rated capacity. A mechanical  

float located in the tank near the vacuum  

valve will rise with the rising liquid level in  

the tank and shut off the vacuum when the  

tank is full. When this occurs, the sump  

cleaner will stop vacuuming. Turn off the  

compressed air to the sump cleaner and  

prepare to discharge the coolant.
