IMPORTANT INSTRUCTIONS BEFORE INSTALLATION Failure to follow these instructions may cause serious bodily injury and/or property damage. Warranty void if product modified, drilled, painted, or altered in any way; if used to WARNING pump hot water, or to pump liquids other than water (such as but not limited to chemicals, fertilizers, flammable liquids, herbicides, mud, tar, cement, wood chips); or otherwise abused. 1. Before installing or servicing your pump, BE CERTAIN pump power source is disconnected. 2.
FINDING THE DEPTH OF YOUR WELL IMPORTANT SELECT CORRECT VOLTAGE The jet tank system installs differently depending on the depth of your well. Tie a small but heavy weight to the end of a piece of string (be sure there is enough string; some wells are very deep). Lower the weight into the well until it reaches the bottom. Take up the slack and mark the string at ground level. Pull the weight out of the well and measure from the bottom of the weight to the ground level mark. This is the depth of your well.
PIPING DRAINING FOR SERVICING OR FOR WINTER Plastic PVC pipe is shown in the illustrations, but galvanized steel pipe may be used if desired. All piping must be clean and free of all foreign matter to prevent clogging. ALL JOINTS AND CONNECTIONS IN THE WELL ASSEMBLY MUST BE AIRTIGHT. Even a pinhole leak will prevent the proper operation of the pump (this is the most common problem). Use thread compound on all threaded joints unless specified otherwise.
STEP Remove pipe clamp and 4 slide Well Seal #RWS4-12 over PVC pipe and onto well casing. Position assembly so twelve inches of PVC pipe protrude from well seal. Alternately turn bolts on well seal counterclockwise until rubber gaskets are tight against well casing and PVC pipe. STEP Cement 1-1/4" PVC elbow 5 onto PVC pipe protruding from well seal. If desired, some length may be cut off of PVC pipe before cementing elbow. Smooth inside of any cut PVC pipe with file or knife.

STEP Cut 1" pipe 2" shorter than 7 1-1/4" PVC ELBOW the 1-1/4" pipe. Smooth rough edges. Cement 1" and 1-1/4" PVC elbows to pipes protruding from the well seal. 1" PVC ELBOW 1" PIPE 2" SHORTER THAN 1-1/4" PIPE STEP Thread 1-1/4" male PVC 8 1 1/4" MALE PVC ADAPTER adapter into top hole in front of tank-mounted pump.
