Not very dependable on higher efficiency equipment. They are great for troubleshooting purposes and the moisture indicator is a plus. Sight glasses became uncommon when we went from 8 seer to 10 seer.

You didn't put any outdoor temps in your message. So I'm assuming a lot. We install multiple brands of equipment. While the charge looks good and matches charging chart, you may have slightly too...
anybody have an idea on forcing fan to run on a Trane Tracer UC400-B? New install, trying to run fans for start up, no controls installed.
wire in stop/start and set your minimum freq to whatever freq you want. leave drive in auto or call ABB, you need model and serial, phone number should be on the drive. make sure safety circuit is...
if your checking the equipment, measurements need to be taken at equipment. the equipment doesn't care what the humidity is in the living room. it only knows what it "sees". any returns leaks, fresh...
the left one. back in the old days you could actually void manufacture's warranty by pulling return on only one side. but that was a long time ago. we seem to have forgotten a lot of stuff that use...
installed five package units on a job. we had a couple of techs working job. pulled old ones off in the morning had to have them running by close of business that day. duct connections were the same....
hot gas goes to condenser coil, if pressure in receiver falls below your "HP control" set point, it will open to maintain pressure to txv. hot gas actually bypasses condenser coil. the two fan...
sounds like there s a programming/set up problem. I have not dealt with Alpine boilers, but with other manufacture's similar products. you should be using CH or DHW mode not both. sensors need to be...
check out sporlan's web site. they have a lot of information. drier cores will release their contaminants when heated. it is why you should always cut them out. again check out sporlan's web site.
make sure your replacement has the heater or it will not work properly
two pumps is just another way of providing flow. probably small Grunfos pumps. two small pumps vs larger pumps. we do it several ways based on what is specified. do not disable either pump. you can...
why not use air? then you can leak test with a water hose. buy the proper nitrogen regulator and save your time and money
why worry about it, change it out next year when it becomes restricted. then when the compressor takes a crap, you can install a new cond unit and move it over so there is 24". when you change the...
most residential equipment is designed for total static of .50" wc. it should be written on model number sticker on equipment somewhere. I didn't see that you listed a brand. type of motor would make...
why? are you not satisfied with recommended gpm or are you trying to become an engineer so you can make up your own control and operation. modern chillers are digitally controlled and will try and...
so where does the oil come from?
why do put a VFD on anything? energy savings! ask how high their utility bills are, you can drastically reduce energy cost, wear and tear on every motor component you can think of, couplings, belts,...
looks like you walked into an existing repair. previous tech is in process of recovering refrigerant with his stealth recovery machine.
should have book and schematic with it, shouldn't be working on VFD's if you don't know
I would disagree timebuilder, I work with real electricians everyday. there is not enough room to post mistakes made by "real electricians". prime example; how do you wire a 3ph motor wrong with a...
low pressure switch? you can probably find the valves somewhere in the condenser.
fluke 1587 is an excellent meter. I have had one for a few years. used properly it will satisfy all your needs. price range around $750.
hahahahahahaha, we installed a multistack with ground loop also using condenser water for building heat. after multiple factory programming updates numerous changes to design programming and constant...
depending on what part of texas you live in, you can really throw your humidity out of whack by adding outside air. I'm in the dfw area, if I had a older house I would not try and add it. if your...
short the test pins on circuit board and it will flash a code. climatemaster makes carrier's wshp
to prevent catastrophic release of refrigerant. temperature and pressure are related. if its hot the pressure is high. so you melt the solder before rupturing components. remember Carlyle "P"...
sorry taking so long to follow up, missed your outside air temp on original post. I've been reading a lot of post, and answers are posted without enough info. I have been a service tech in dallas tx...
just put some fireplace screens in front of your low return grills to keep small children and pet from being sucked into them.
I would pull combustion fan and shop vac housing and also insure tube connection is clean. check pressure port with a magnehelic before and after cleaning. also check vent pipe for restrictions. I...
if you do that in north texas, you better have a drain pan under your furnace and a big o' box of sheet metal parts next to it.
I have the same unit in my house, within a few months of your serial number. I could not even begin to tell you what pressures should be without indoor and outdoor temps.
Yes you can, but without training and their gateway it will not do you any good. Try "mylinkdrive.com" you will find a bunch of info
mylinkdrive.com is tech support sight. Mitsubishi doesn't tell anybody about.
