I am faced with two Barker display cases that have the labels worn off. I need to determine/find or best estimate the btu per linear foot. I checked with google search and found a series of case...
or in thinking that I am trying to protect the system from surges /quick on /offs ... supplying from the surge outlet only would solve this as well
oh so simple solution but at he same time so frustrating, I will let you know if it works
so a small night light or some other small load plugged into the outlet would correct the problem
Sorry BN450M-CA
APC by Schneider Electric
BM-450M-CA
Looking at the specs it gives no minimum load
I have had a issue with quick on /off power failures that have resulted in a partial loss of the hvac programming that required a restore defaults and reprogramming of the zone control. I have also...
Thanks I will check Kele
good point thanks , I just need to make this go away
I posted this in Pros forum as well
I am wanting to install a circuit protection for a York Communicating zone control system.
I have a system the has been subject on two occasions to quick...
Trane has stepped up and is providing compressors and proper txvs on their dime ( out of warranty). Bill of material sheet for that unit from factory shows what parts are to be in in listed and it is...
Got word today that Trane is providing new compressors and the correct TXV's. Well done for Trane in stepping up to make this right
would like to get my hands on a drawing of the refrigerant piping arrangement for the original cooling only unit and get a Trane heat pump one as well to compare that is on site.
I do not know any of the trane guys on the island. only spoke with a couple of fellas on the phone from their commercial department
where is the commissioning/start up sheet
customer is well aware of what is going on..thanks
yesterday I was provided a bill of materials for this conversion and 5 ton txv's not listed. List identified 12.5 ton and 8.5 ton
The other thing that is giving me pause for thought and concern, is the bottom 10 inches of one of the circuits has been removed(ends welded) why? Were the condenser fan motors changed and or fan...
From what I am told they did not have a heat pump large enough to meet the customers needs at the time so a cooling only was converted. whether or not that is the truth ?????this is what is I was...
Well someone is going to have to own this one because it was special order with a tag from factory identifying as a heat pump I have picture of the label
Taken over an account that has TDC301 that was a cooling only and converted into heat pump, 2 stage unit 13.5 ton and 7.5 ton capacity compressors. just over 5 years old. first stage compressor is...

Re- Nu additive worked in all four of the York heat pumps I used it on. One was a real snot, but with time it worked.
thanks for the info
Nothing was said about changing the reversing valve when the compressor was changed and considering the problem did not go away the problem source looks to be heading in that direction. No issues in...
HP reading taken on hot gas line and the noise is a prolonged as many people have commented on it when visiting.
aux heater is 15 kw and when I saw the 96 degree SA temp I went and checked to see if aux heat was energized and it was not( Honeywell focus pro 8000 touch screen). Thinking I am going to have to...
]The numbers are bothering me. You've only got about a 4* TD at the outdoor unit, and an indoor SCT of about 84* at 250 psi. You have a delta-t of 26* with a 69* return, giving you about a 95*...
Are you working on a HPXA16, or an XP16? Is it a CB31MV, or a CBX32MV? HPXA16 with CBX32MV
Head pressure only 250 on a 45 degree day - was it pretty cool in the house? Return air at 69
You heard...
I attend to a new customer yesterday for a general heat pump maintenance check. They explained to me there on going problem with the system they had installed in 2008.
The complaint is a high...
was thinking overnight....maybe water fill valve is not fully closing. keep water temp higher not allowing cold water for proper ice formation
Ok thanks for the update. Pin count is set for 12 on G1 less 85 ambient and less the 68 water temp.
any one have any trouble shooting experience with unit.
very poor ice production meaning poor cube formation before defrost
new water curtain installed and distribution pipe as previous was...
original post indicates .1SP on RA plenum before filter....no way of getting true SP after coil and filter
Good to know and confirms to me at least that dropping the air speed proved my theory
according to installation instruction this is a multi position coil and this did not start on day one of installation so it work for a while
traped and primed
Since dropping the fan speed, water issues have ceased. To me that proves my suspicion about the filter.
no furnace.. typical heat pump air handler. "A" coil above blower and heater, filter above coil then the ra plenum box
I have inherited a problem that has been on going for about 4years
Lennox CB29M-46-1P
Matched with a 4ton 10seer Armstrong concept ac
condensate is soaking the blower and heater compartments...
good point on the brazing...I can only assume they are doing it correctly...but then again. I will pass on about the service bulletin info. Can you provide bulletin??
Indeed they are danfoss valves. I wonder if they are aware of this issue?
These would be in Frigidaire heat pumps
I was in the local supplier today and I was asked if I had ever seen failures such as ruptured power heads and sensing bulbs that have blown off. He has a collection of returned txv's. I am not a...
