## Questions & Answers

**Q: My dc 24v supply current is 1.2a. it's going to work? my pump is currently putting a 80 psi in the the system with the faucet opened. this wiil fit?**
A: This TSO shutoff is for the Aquatec pumps. I use it with the 8800 pump & the included 24v AC transformer (output). The switch turns on at 19 psi and turns off at 40 psi using the Watts RO and tank. It works perfectly with 24v AC output but don't know if it will work with DC output.

**Q: How does this connect to the transformer?  Will it work with other brands other than aqua tech?  I am considering a ronaqua one.**
A: This is for use with the aquatec pump on an RO system only. The fittings are specific to connect to the pump and transformer. Not sure if any others would work with it

**Q: Where exactly is the marking of direction of flow? Is the "in" is on the red terminal lugs side?**
A: There is no direction as it is a simple pressure switch.  Flow stops with a float switch.  Pressure builds and initiates the off position on the switch.  When pressure drops the switch engages the power.  My outlet is connected to the side with the lugs.

**Q: does it shutoff pump if no water supply and tank is below 40 psi?**
A: It shuts off when a set water pressure is reached. Back  on when pressure is bellow setting . Nothing more.
