CONNECTING TO THE TANK/WATER SYSTEM

WARNING: Risk of hazardous pressure. Submersible pumps can develop very high pressure in some situations. To prevent tank blowup,
install a pressure relief valve able to pass full pump flow at 75 PSI (517kPa) when using an air over water pressure tank. Install a pressure
relief valve capable of passing entire pump flow at 100 PSI (690 kPa) when using a pre-charged pressure tank. Install this relief valve
between the pump and tank.
WARNING: Pipe joint compound can cause cracking in plastics. Use only Teflon tape on joints in plastic pipe.
NOTICE: Allowing the pump or piping system to freeze may severely damage the pump and will void the warranty. Protect the pump and entire
piping system (including pressure tank) from freezing.
PRE-CHARGED PRESSURE TANK HOOKUP
This diagram shows a typical submersible installation with a pre-charged tank installation:
NOTICE: Two-wire motors do not use a control box. Run the motor wire from the pressure switch directly to the motor. See the Wiring instructions in
this manual.
NOTICE: Check air pre-charge in the tank before starting the pump. Adjust the pre-charge to 2 PSI below the pump cut-in setting. (For example, a
pre-charge tank used with a 30-50 switch should be pre- charged with air to 28 PSI. Adjust the pre-charge by either adding or bleeding air through the
tire valve located on top of the tank. Check pre-charge annually and adjust as needed.
