First time I have heard of anyone installing a filter dryer inside near the coil. Never seem one before, istalled that way. Curious, is there any benefit in that method or reason for doing so. Where I school it was never mentioned. We were shown and instructed to install outside near the condensing unit.
The only advantage to installing it indoors is keeping it out of the weather.
Most get the paint burnt during brazing, and start to rust immediately.
Either place is fine, but be sure you look both places when servicing, or doing a changeout.
Never install a drier without removing the old one.
It is considered good practice to install a filter drier in a new install.
You risk plugging the metering device, if you leave it out, Especially if you don't use nitrogen while brazing.
