INSTALLING THE THERMOSTATIC EXPANSION VALVE

The larger fitting on the thermostatic expansion valve connects with a Swagelok to one of the plate tubes. In a multiple plate series system ½” copper jumper lines will connect the plates to each other. The last plate has a ½” return line to the compressor. The feeler bulb from the valve must be strapped to this return line inside the refrigerated space. Plan the tube run to allow for the length of the capillary (about 50 “). On a vertical run the capillary tube connection should be up above the bulb. It is critical that the feeler bulb be in excellent contact with the copper tube. Be sure to locate the feeler on a strait section of tube. Strap the bulb to the line with the two copper straps, bolts, and nuts. Coil and secure the excess capillary tube between the valve and bulb with nylon cable ties. Do not let the capillary tube contact other tubes or the plate surfaces.

The valve is supplied by a ¼” copper tube from the compressor. This is a Swagelok connection.
