Default Santa Fe Classic Dehumidifier

This looks like the perfect unit for my basement!
Buy Santa Fe Classic Basement & Whole House Dehumidifier (4029700) | Thermastor 4029700

Capacity @ AHAM: 110 Pints/Day
Capacity @ Saturation: 180 Pints/Day
Amp Draw: 6.4 Amps
CFM: 275 CFM
Operating Temp. Range: 56 - 95F

Wow! Listed at $1,671.00 Got it off craigslist for $100
See: http://ecorenovator.org/forum/sale-t...list-used.html

It seems to be working Okay. In ideal conditions, it pumped a cup of water in about 35 minutes.
After I install some filters, I'll give it a good test run.. It does use about 6.4 Amps at 120vac..

Gut shots? Or did it already get installed somewhere?

I think it's a 6 or 7 years old. Recently replaced. No explanation of why..
But, when I did a short test the day of delivery, it was idea weather for a test. Raining & 80F. in an open garage.
Looking at the amount of water that came out. I estimate 1/2 quart per hour. (or less).
Spec says under idea conditions, 2 quarts per hour.

On some of the reviews I've seen, there were owners saying that refrigerant slowly leaked out. (4 or 5 years)
I hope that's all that's wrong with this one.Hope it just needs a shot of R410A..
Planning to test some more when I get some air filters.

Noticed the compressor got really hot. Wondering what the normal operating temperature is.?.

The maintenance port is out on a thin tube..
I can see how it might get broke off when removing the cap..

Default Pressure test?

If I put a gauge on the low pressure port while the unit is running, I should see about 240 PSI?
Or, is that the Max pressure? On a mini-split, it seems like 130-140 PSI is common..

Default Kinda working..

I'm not so sure.. I found a user that's had a lot of problems with this model..
Sante Fe Classic Quality Issues

He's included five links to YouTube videos in his posts..

Mine seems to be working poorly. Only getting about a quart during a 1 hour run..
Temp 70F with RH between 60 & 70 percent.

I'm wondering if a Superheat test could tell me anything..
First, I'll have to find out what the 'standard' Superheat temperature is for this model. At 70F & 70%RH..

~~~~
After a 1/2 hour warm up, I did a little testing of the input air vs the output air.
Input air was 62%RH @ 73deg
Output was 38%RH @ 82deg
A change of 24%RH & 9 deg.

Maybe I'm lucky or something, but we bought a Thermastor Santa Fe Classic dehumidifier in 2003. We put it in the living room to use as a whole house dehumidifier in summer. It's been working perfectly ever since.

The house temperature is typically 75 to 80 deg F, humidity 45 to 50%. The house is well insulated, so we rarely use the AC. Also, the AC does not do a good job of removing moisture.

My wife likes it dry, sometimes the humidity gets down to 40%.

Wow! That sounds like money well spent.
Is it a R22 or R401a version? I'm also very interested in the temperature of the input air, vs the output air.
I think it might be a quick way to determine the correct refrigerant load.

If I can get this one working to spec, it would be fantastic for our musky basement..

The nameplate says R22. It's running right now. The room temperature is 76 deg F, 53% RH, outlet temperature is 100 deg F. The outlet temperature reading may be a little low, it's a cheap little thermometer laying on the floor.
