This prep table has two TXV's and two LLSV's. The box TXV/LLSV appears to be controlled by a stat at the evap coil. But I can't find anything which controls to upper deck LLSV except a manual rocker switch.
Is that the way this box is controlled?
It seems to have sufficient SC to have the box TXV controlling properly . But even with the box temp at 45º F. the SSH was way high.
The compressor / condensing unit is said to be new. So I'm not sure if they match (the condensing unit and the case). But what I want to know is: where the hell is the extra amp coming from? I had to jump out the O/L to even get the above data.
Since these readings were taken I blasted out the condenser coil with a garden hose - because I ended up cleaning out several others in the place - so the numbers may have changed slightly.
Nonetheless: what do you all think?
