If your system can develop more than 100

of tank blow-up.
NOTICE: DO NOT use any type of lubricant other than
water on Hose to Plastic fittings.
If rigid piping is installed to elbow on inlet flange, BE SURE

of the typical installations on Page 4 and 5. Use Teflon tape
on all threaded connections to tank.
BASIC TOOLS AND MATERIALS NEEDED
INSTALLATION
Please read our instructions before you install and use your
tank. This will help you obtain full benefits from this tank.
It will also help you avoid needless service expense that
result from causes we cannot control and cannot cover in
our Warranty.
MATERIALS
Plastic Pipe and Fittings (as required to complete job).
Teflon Tape (DO NOT use pipe joint compound on
plastic fittings) or Plasto-Joint Stik*
MATERIALS
Galvanized Pipe and Fittings (as required to complete job).
Pipe Joint Compound or Teflon tape
Standard pipe fittings, such as nipples, tees and elbows
must be purchased locally. If you are using a horizontal jet
pump mounted on top of tank, Figures 3, 4 and 5, Kit No.
2788 is required. See Page 10 for contents of kit.
If your present system has an air volume control (AVC), re-
move it and plug AVC port on pump.
Complete pump, tank, and piping system MUST be pro-
tected against below freezing temperature. Failure to do
so could cause severe damage and voids the warranty.
