Attaching the Siphon & Vacuum Lines with Factory Installed Siphon Assemblies
Disconnect, lock out, and tag power at the panel before servicing the
pump.
When servicing equipment, use non-sparking tools and use caution when removing or installing
equipment to avoid generating a spark.
1.
Remove the 1/4 inch pipe plug from the siphon nozzle.
Care should be taken to insure that the internal portions of the siphon nozzle and parts in-
cluded in the siphon kit are clean and free of debris or contamination during assembly.
Before installing pipe threads apply an adequate amount of fresh, UL classified for pe-
troleum, non-setting thread sealant.
2.
Coat both of the male threads of the 1/4 X 2 inch long nipple with pipe sealant. Thread one end of the nipple
into the siphon nozzle and the other end into the 1/4 x 3/8 inch reduction bushing.
3.
Apply pipe sealant to the male threads of the reduction bushing and thread it into the 3/8 inch female elbow.
4.
Apply pipe sealant to the male threads of the siphon check valve and thread it into the 3/8 inch female elbow.
5.
Apply pipe sealant to the male pipe threads of the compression fitting elbow and thread it into the 1/4 inch
hole in the siphon check valve.
