Installation

NOTICE

Failure to use thermal paste could result in erratic temperature sensing resulting in equipment damage.

Freezestat

A Bulb-well (located inside the remote panel) must be installed in the leaving water piping as close to the chiller barrel 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. Refer to Figure 22 for the recommended location. Figure 24 illustrates the Bulb- well dimensions.
