What was the oil mgmt system used with the Hussmann TD? I ask because there are several stores with a similar setup; 2 comps for LT, 2 for MT and 2 for HT...all on common piping and one receiver. ...

Incandescent bulbs are also resistive loads. They are heaters.

I've also bought THESE thanks to another link posted here years ago. Seems all they have left are part #'s RF3, RF16, RF67 and RF72.

I had nothing to add by the time I read this, but I am impressed by your follow through with this issue. Can see why John speaks highly of you.

Which is voted funniest movie of all time

Another tip. Use the recovery machine to pump into the suction header instead of tanks.

Yes, and sadly after the "PM" has been completed.

Yup, have several, 410a Munters units in the desert run over 600# discharge, but that PT scale is wrong,

If the thermostat is satisfying and shutting down, why not turn down the thermostat?? Also, you may have overcharged the unit, torch the receiver to find the level.

I phone up the guy on EVERY callback. Not an ass chewing, just a 'this is what I found' deal. If he has pride, things will change. If not, talk to the boss. I also tell every guy that I want a...

Take a glance at the TXV external equalizer, see if it is bypassing into the suction, it may be why the suction line is a lot colder than the other unit but the coil itself is warm. Or the coil is...

IR here...we get 100% match up to 6% deduction. Trane must have had it better because ours did not get axed.

An experienced manager is more understanding that the newly promoted hot shots. Finding those are satisfying, though.

It it's 134a, that HPC needs to be at least 100# lower and the CFM cut in lower

Thanks, ascj

That is not a bypass. It also does not equalize high and low side in the off cycle, as some believe. That senses pressure at the outlet of multicircuited coils to compensate for the bigger pressure...

Are you talking about the external equalizer???? Is this 'bypass' coming off the valve body or the piping before the valve??

Dern, was hoping this was some kind of new thing, or some plausible explanation.

Including the ambient fans up top and the fans under the roof panels?

#2 can happen if a mechanical subcooler is being used to increase capacity. If the rack is a little low then the liquid is no longer at 50*F but a lot warmer. All the fixture TXV's open up, trying...

Reefer guy here but saw this and it interested me. The first 2 pics are one unit and the second 2 pics are another unit. That PVC goes to a smoke detector inside the blower compartments and, as you...

Yes, I see it done. It then gets replaced with a commercial grade 20a device. The sparky showed me the code where it was acceptable. Mostly, it just gets wired in hot off of coil power.
Oh, the...

Not sure, brother. Looks like a call is in order.

Of all those, I think certified welder is highest, industrial next. Safford area I like as well, Morency is the big mine area there. Heavy Mormon there.
