## Questions & Answers

**Q: install instructions for pump water  pressure switch**
A: Asuming you are replacing an existing pressure switch, it's a piece of cake. But first I must ask it you are sure the problem is with the switch. I would suggest yo spend a little time doing a few checks. Turn off the power to the switch/pump at the breaker. Remove the plastic cover and look for the contacts. Check the contacts for marks of arcing and carbon build up. Push the overcenter arm to open the contacts and clean the contacts with an emory board/nail file type. When you see clean metal on the contact mating surfaces trip the OC bar back to close the contacts. Energize the circuit and see if the pump runs. If it does not find a volt meter somewhere and measure the voltage across L1 and L2 contacts (from the service panel) then repeat on Load1 and Load 2 (the wires going to the pump). Basicly you are checking the voltage from the service panel and then to the pump. If there is no power on the line side of the switch, there is a problem between the panel and the switch. If there is voltage on the wires heading to the pump the pressure switch is doing its job and the pump wiring or pump are at fault.. If theres voltage in but not out of the switch then replace the switch. Again shut off the power at the service panel. Drain the water system to releive any pressure in the system. Take a picture of the wiring to be sure the new unit is installed identically. Label and remove the wires from their respective terminals. Remove the the cable connector from the sides of the unit to be reused  in the new unit. Unscrew the unit from the water system being sure not to stress the connection point on the system. Use a back-up wrench. Pipe dope the new unit's threads an screw it in. Do not over tighten it. Install the cable connects, connect the wires and install the cover. Restore power to the system and see if it works.

**Q: Wire connections -- Line Vs. Load. Working with 240v. My unit does not cut off at all and builds excessive pressure causing leeks. Wires are black & w**
A: Turn the circuit breaker off then double check your wiring. You should have 4 wires, a white & a black which is line in, and another set of white and black wires which is line out or load. If it looks  okay check your settings., the cut-in  should be set at about 30 lbs and the cut out should be about 60 lbs.   If all that is okay you may have a defective control. Make sure you turn the circuit breaker on after you finish checking the above.  If you can't tell which is line-in you may need a voltage meter to check it.  Good luck.

**Q: Does this switch has a low pressure cutoff?**
A: I'm not sure what you mean by "low pressure cutoff". However this switch is designed to maintain pressure from your well pump between 30 and 50 psi. If the pressure in the system drops below 30 psi, it kicks the pump on, once it hits 50 psi it kicks the pump off.

**Q: my pumptrol square D model number is 9013fsg  2   30/50 psi    is it the same as a  fsg2j221cp 30/50 can i use it?**
A: Honest answer:  I don't know.   Having admitted that, I will add for your own decision making:  (1) Did Square D just change their model number as a product update?  i.e., (2) Are the liquid plumbing fittings the same?  (3) Do both models have the same number of hot, neutral, and ground electrical connections?  (4) Are the electrical breaker/contact points the same size?  (5) Do you have an on/off switch upstream of the Square D to control your system?  (6) Is the system fuse-protected upstream from your switch?  If the answers to #2-6 are all "yes", it may be worth a try.  But if in doubt, do not endanger yourself or anyone else!  And feel free to get a second opinion.
