Thousands of one room country school houses had a wood burning stove inside.
The lady teacher had to arrive an hour early to start the fire.
I am on a Museum board, we have a 1 room schoolhouse...
I believe they work both ways.
You could hear air venting when it comes out of defrost.
I did the electrical work on a fair sized combo WIC/WIF.
Had the electrical diagrams for all components, however the page for the relief valve heater was missing.
There was no obvious wiring...
Perhaps leaky door gaskets and lack of exercise on air valve with little use.
More visits would move the ice on the parts and break it free.
About 30 years ago I worked with the state on the clean up of ground water at 2 small gas stations. This took about 15 years to get progress.
The main geologist from the state was telling me that...
Being 2 stage, wouldn't there be 2 pressure switches to check?
Isn't there any 120 volt circuit in the building?
Usually with 480 there is a step down transformer for a 240/120 volt panel.
Any standard outlets in the building....they would be 120 volt.
Tstat may have a heat anticipator that is adjusted wrong.
Did you say that the clean clothes from the dry cleaner were returned to this building?
Is there residual chemical left on the clothes from the dry cleaning process?
If enough clothing stored...
You should listen to the worker bees in the building.
Had a call for water on the floor in a nursing home, coming out from under the wall.
RTU was above so you assumed plugged cond drain.
Look...
Before cutting copper tubing to add a fitting or FD, I sand the copper. Easier to do a stationary piece than loose ends flopping around and it keeps the grit out of the open pipe.
Sand the end...
Wild leg needs to be ID with orange if a neutral (white or gray) is in the same box.
I always mark with orange in any event.
Not all orange wires are Wild Leg---but all Wild Legs are orange (if...
Could it be that the high limit has power on it only in the heat mode?
I have had the problem that slctech described.
Years ago I used the wild leg (AKA B phase--208 or so to ground) and a 120 to ground leg for several mini's. I was trying to balance the transformer bank as there was little 3 phase load in the...
Our small movie theater had a similar unit but may have been made by Chrysler-Airtemp?
It was mounted with the bottom half in the 1/2 basement. It would have been put in there in the 50's....when...
You obviously have enough common sense to use the log lighter.
You have to remember how many others do not.
This was a probably discontinued feature as liability issues strung up.
Many might...
I found it is easy to overlook the pilot flame gas pressure setting.
Too high and the flame lifts away from the flame sensor....bigger is not better.
I have visions of bent parts from trying to shift and somewhat compress non compressible liquid.
What cold pressure is on the system and then what is the hot pressure?
How often does this happen?
Is 410A worth stealing? I can't see getting that much of the charge without a recovery machine.
So just to stir the pot:
What is 3.1416 (Pi) doing in an electrical equation.
How does the geometry constant fit in this electrical measuring?
A constant we can visibly see with the circle...
If you post this picture on HeatingHelp.com, there are a lot of wetheads there more fluent in this type of device.
If there are actually 4 ports on it then it looks like some adjustable 4 way mixing valve.
Which has constant flow on both loops.
How many pumps are involved?
I have "Infloor" manifolds which...
The only thing I save is job site pictures, They are scattered all over my computer.
Can never find what I am looking for so my granddaughter's boyfriend said he would help.
He recommended the...
I keep one large screwdriver dedicated to being the "beater".
Lock Nut tightening, wood/concrete chiseling and more.
Grind the end as needed. Once upon a time would trade back in at Sears for...
Have anyone checked the gas pressure drop when the furnace fires?
Gas company pressure might drop in heating seasons with load.
Your gas co regulator could be slow to respond and the pilot...
Looks like rigid galv pipe that is PVC coated with shrink tube on the threaded couplings.
We are assuming that this is an air handler only, with coil in the bottom.
Not a gas furnace?
That photo made the front cover of a electrical trade magazine in that year.
We have a community collage here with a 1 1/2 year long lineman course.
When my son attended there, were 2 boys...
I have had good luck testing relief valves annually.
I always let them flow for a couple of seconds and snap them shut, might do this twice.
The inspectors just lift it to flow minimum water...
Hot water heating (only) boilers have only a pressure relief valve. Typically 30 PSI, some systems may be rated for 50 PSI.
They do have temp limit controls of at least 2 (today) and with the...
Pictures of the relays and transformer would be good.
When checking controls, fuses etc I check phase to phase and not immediately check to ground, that is fairly misleading in troubleshooting. ...
I had a similar issue with a 3 ton resi HP.
Charge looked good but wouldn't cool house very well or quick.
HO said that 2nd floor vent directly above the AH seemed to be always warm.
Amp...
Where did you place your meter leads to get this reading?
Sounds like you measured the L1 to ground, not the actual coil.
The old school method was to gauge up on the system and close the liquid line valve.
Pump the system down to almost 0 PSI on the suction side, that would also show on the liquid side. The...
I would also check for tstat control wiring to the AC from the AH.
There could be a call for defrost heaters if someone jacked up the wiring connections.
I would call it a 110 volt. Could almost be considered a 20 amp design.
It almost looks polarized, is one slot larger than the other?
Grounding would be available thru the conduit if desired.
...
IIRC, there were organizations that would pay for the LD call within the states from donations.
AT&T had 3 LD rates, daytime was the highest maybe .30 or more per minute.
Evening was more...
This would best show you where to place the Placebo tstats.
But I do believe it is dryer than air.
Yes, it can blow some nasties out of the piping.
I have found it stable enough on pressure/temp in that it will hold 500 PSI overnight with very little...
I meant my first AC install was done in 1982 by me.
As I age I try to avoid the use of... I...Me...and My.
It requires some extra thinking and does not always come out right.
The first install of split AC units were in 1982.
This was for my duplex rental.
The units were "Tappan" back when it was a good solid company before the merger into Norteck.
The 1 1/4 Ton...
Nitrogen is susposally "dry" and would remove some moisture.
Also it is fairly consistent in pressure regardless of temperature, so is used as leak test as you watch for decay of test pressure.
...
Well, it is not good. Obliviously no 3rd grounding wire.
Sometimes switched neutral for lights, leaving a hot at the light fixture when "off".
Might share neutrals with other circuits,...
I have replaced a lot of Knob and Tube wiring.
Never did see "bare" copper wires on the knobs ("eggs")it was just individual conductors.
Good system if all joints were soldered and the wires...
I missed out on the era of subluminal advertising for drive-in's.
The film travels at 24 frames per second, that is how you get the "movies".
Rapid showing of still pictures.
So perhaps 2-4...
Mustang years 64.5, 65, and 66 had the same basic body design with only minor subtle changes. 4 or 5 lug nuts. Dashboard design. Gas cap. Grill design etc.
Also, Bazooka Joe they were not 2 way...
I usually swage the end, no need to ream.
Or I use pipe cleaners. The standard size get 2 lengths connected with the "Western Union" wire splice.....old time splicing method for telegraph wires....
Is the rotation correct?
Is the blade upside down?
Is the blade adjusted at the correct height to get the air flow up and away, not to low so the air hits the bottom of the fan shroud.
