Q: Does this include the cable connecting to the monitor?
A: Yes, that is correct. The cable is just not pictured, but it is build in to the cell just like your original.
Q: I have a SI series but don't know, manual doesn't say, if its a 30 or 45? I have a 18,000 gallon pool. is the -30 and -45 the same overall length? Connections to the controller the same? I don't want to replumb the system. Thanks.
A: Both cells are the same length and connections. The cell should have two silver stickers on it, each will reference the model and/or gallon capacity. If you are unsure, please contact tech support at 888-206-9938 ext:2 and we'll be happy to help.
Q: is the whole unit sold or just the cell, and how easy to install,?
A: This item is just the replacement cell if you already have an existing Si-30 salt chlorine generator. You can replace an old cell typically in just minutes. If you need a comple salt chlorinator unit, give us a call and we'll be glad to help: 888-206-9938 ext:1
