Servicing

The gray plastic mounting panel carrying the pump, valves and electrical control box can be removed for 
servicing. 

To remove the mounting panel:

1.

Remove the three bolts holding the 
pail.  Separate the interior frame.   

2.

Remove the three bolts holding the 
mounting panel.

3.

Lift the assembly straight up with the 
wires attached.  Lay the panel on top of 
the container.

The pump impeller can be serviced without removing the pump from the mounting panel.  Remove the four 
brass screws on the bottom of the pump to access the impeller.  A spare impeller and seal are supplied with 
each Sacksafoam II unit. 

If a solenoid valve does not operate properly, remove the blue coil by pulling off the securing clips (do not 
lose the wave washer installed under the coil).  

Undo the four bolts and gently remove the top of the valve from the diaphragm.  Clean the inside of the valve 
and the diaphragm using mild soap and water (do not lose the small spring that fits inside the metal stem 
attached to the diaphragm). 

Test the unit after any servicing.
