Pulsafeeder Chemical Feed Pump wiring

[Wellmate]

I am installing a pulsafeeder chemical solution pump (220v) in my well water supply line just infront of the pressure tank. I would like to install it so it operates when the well pump is running and filling the pressure tank. My question is......do i wire the pulsafeeder pump to the pump switch itself...or to the control box or???. I would like to know, where i need to cut the wires and splice it in...or if i just wire it to existing terminals. Thanks in advance

so it operates when the well pump is running

Wire it in parallel with the well pump motor, assuming the chem. pump motor is also 220v. Depending on the current draw of the chem. pump you might need to resize wire or breakers or make other adjustments.

You can wire it to the "load" side of the pressure switch, or tie it in with L1 and L2 in the control box.
