Coolant Filter Question. and DCA

I'm thinking of installing a coolant filter on a 1989 7.3. It has 108000 Mi. on it and needs coolant service.

No instructions so I don't know how it is installed?

Ford Superduty Powerstroke 2003-2007 6.0L Coolant Filter Kit
http://www.dfuser.com/Install%20Guid...filter_kit.pdf

The instructions say to T into heater supply line and the degas bottle line.
It looks like the powerstroke has a different system then the IDI?
Will installing these filters defeat the radiator pressure cap?
Has anyone with one installed ever pressure tested their system?

Is it safe to run DCA4 in these motors?
