Yeah them damn things are a guaranteed leak at some point...

no salt in Canada ....driers never rust out.....

never had one rust out..... have had a couple of expansion valves rust out .... no salt in the air here it freezes....lol

30 years and you haven't had a drier rust out and leak? I had several of them this summer.

Catch-All Filter-Driers are most effective in the liquid line. Place the
filter-drier immediately ahead of other liquid line controls, such as the
thermostatic expansion valve, solenoid valve, and See•All Moisture &
Liquid Indicator. When applied in this way, the Catch-All provides
maximum protection for the expansion valve and solenoid valve from
dirt that may be in the system. If the system contains appreciable
moisture, then this location gives the best results in protecting the
expansion valve from freeze-up. If possible, place the filter-drier in a
cold location. The acid removal ability of the Catch-All Filter-Drier is
the same whether it is installed in the liquid line or suction line. End:

Note they say to place the drier in a cold location, do you know why? This is a better environment for the drier to retain the moisture it has collected. By heating up the drier it can cause it to release the moisture it has collected. Having the drier outside in the sun is not a good location.

Best practice:
Place Heat Pump filter driers horizontal.
Place all liquid line filter driers indoors just before the TXV in a cool indoor environment. "If possible, place the filter-drier in a
cold location."

my 30 years in the trade says I do not agree.... i have never had a problem..... and I actually installed a drier inside the other day just to say I had done it .... guess what ...it worked like the thousands of other installs I have done...

Real neat.. I have always put the drier near the evap as well.. nice job!

nice install. real neat..I like it..

oh man...here we go...... does it really matter...i do not think so....

They actually (manufactures) prefer them to be horizontally installed.

I didn't say they "had" to be......they are supposed to be.

dries do not have to be installed vertically..... where is this info from...... and yes great work well done...

not only that, but alot of times it's easier to get to inside if you have to change it in the future. and driers are supposed to be installed vertically, so they don't trap oil in the canister.....makes that easier too.

nice install!

No, I don't use mastic unless it is in a crawl or attic. Furnace and both supply and return duct are in the same conditioned space. Doesn't matter.

Hmmm...

Looks nice

closer to the evap. Thats where it belongs

Very nice install.

+1 on the forming of the lineset. Very clean looking.

As for the condensate float, the inspector flagged my 1st floor unit (downdraft) for not having a coil pan float... Upstairs unit is in the attic and has a secondary float switch. Inspectors vary in what they deem code. Otherwise, AWESOME install.
