If a flange-type valve is to be used to return the oil and the flange is drilled and 
tapped to a ¼ in. female NPT fitting, then the drilled hole should be offset to the 
top  of  the  internal  valve  diameter  to  prevent  an  air  pocket  from  being  trapped 
behind the flange (see Figure 8—11). 

 

Figure 8—11: Flange example 

Figure 8—12 depicts the Return Assembly kit. 

 

Figure 8—12: Return Assembly kit 

 

All pipe fittings should be tight and all threaded pipe fittings tightly wrapped with 
PTFE tape with a light coating of PTFE paste or other quality pipe thread sealant 
applied  over  the  taped  male  threads  to  prevent  leaks.  Both  of  these  items  are 
included in the  product installation  kit. 

Note: GE recommends two wraps of PTFE tape or 

three wraps for large pipe fittings.
