Someone elses machine




Close up of brace supporting tube. Same TXV as we are using with a solenoid valve.




Rebuilding Cohan. Using up a solenoid I had around. Simple tube brace.




TXV and solenoid installed to right of fan in DVX cabinet. Things could be neater, could use a better brace, could be more to front of cabinet. Otherwise it works. it is important to be able to look directly down the orifice bore and observe the diaphragm pin. The superheat is easy to get to with an allen key. The TXV bulb reaches outside the machine to the suction line




Detail of brace. A heavy copper plate would work better.




Installation so far. Note unit is bolted to unistrut on wall. No access to back of cabinet. This is a double cellar. Sensor wires are hanging out of return ducts. A hole is drilled in those elbows and the wire is brought outside the duct. The other feed duct is to the far left.
