    Well, I finally got time to get back over there and finish the job. I strapped the sensor from an A419 controller to the suction line about two inches from where it exits the box, immediately before...

    Just noticed this post. The bypass and injection solenoids are energized with the compressor contactor. The bypass valve is controlled by suction pressure and the desuperheater is controlled by...

    These aren't the best pics, just what I had on my phone. The hot gas ties into the suction in the bottom left of the picture then the liquid is injected just before the accumulator. This condenser is...

    I'm using semi hermetic compressors with discharge bypass for capacity control and liquid injection as a desuperheater. On the compressors that I have running, I have around 35 degrees superheat at...

    Something else I didn't mention is that all the other evaps are being controlled by electronic controllers, either A419 or existing factory controls that open a solenoid. The compressors are ran off...

    The suction line is a 3/8 line that doesn't tie into the 5/8 common header until about 30 feet from the evaporator. If I strapped a sensor to the line immediately after the coil do you think I would...

    Only 2 out of 16 had Cap tubes, and yes, I did replace them with txv's. There was originally a variety of refrigerants and I have switched them all to 404a with txv's and new condensers. This...

    Yes, sorry I should have been more clear on that. I do plan on using a liquid line solenoid, I'm just not sure how to go about controlling the solenoid. I can't see a way to properly sense box temp....

    How to control temp on medium temp box?

    I'll start by saying I have a lot of hvac experience, but haven't done much refrigeration. I'm in the process of retrofitting a hotel kitchen from self contained condensers to remote condensers. I...

    Agreed. Experience has taught me to always get replacement motors directly from Liebert. Aftermarket motors, even with ball bearings, just don't cut it.

    I've seen the same thing on a Trane. New 410A install by our company that was only slightly overcharged and rapidly cycling on high pressure switch. Keep is informed.

    Look closer at the pic. L1 and T1 are twisted together, bypassing the disconnect. That's what is so dangerous.
