Figure 29: Bump Assembly 

 

Head Removal 

 

This procedure is to be followed when any kind of maintenance or repair is required inside the 
filter tank which cannot be accessed from the various open connections or manways. 

All Defender filters are equipped with a davit head removal system,

 

except for older domed-

headed filters and the SP-18 and SP-29 Assero Defender filters. The tank-mounted bottle jack 
drives a shaft attached to the head of the tank. Due to the infrequent use of the davit, a 
lubricating penetrating oil for the davit must be applied before each operation. 

The head gasket is required to be replaced whenever the head is removed. Be sure to have a 
new head gasket on hand before performing this procedure.  

1.  Bump and perform a drain and rinse to remove debris from the tank.
