Adding a Model AIF10 Kenmore Iron Filter inline with Softener

[Rockyhammock]

I have had a Kenmore Water Softener, model 625.383560 for a couple years now. Constant problems have forced me to add a Kenmore Iron Filter, model AIF10.

 My question is this and it is probably a dumb one. Being the IF will come just after the pump and before the WS during the Iron Filter setup, I am to purge the water line to house and flush pipes, expel air from filter and test installation for leaks. The bypass valve must be in the "bypass" position on the IF. I then open some faucets in the house. Eventually once faucets appear free from air, the bypass valve is returned to the "service" position.

 My question is "what about the Water softener during this time?" Is it also in Bypass Mode?  Seems like it would have to be. Am I correct?

Yes, otherwise you would put air into the WS.
