chiller as possible. It should be located upstream of the
temperature sensor location. The freezestat, located
within the remote panel, is equipped with a remote
sensing bulb and 20 feet of capillary tube. The remote
sensing bulb must be installed by the installing
personnel. Thermal paste is also provided inside the
remote panel and must be used when installing the
bulb into the bulb-well. Figure above illustrates the
bulbwell dimensions.
