2. Application Note: On low cutout applications, control without a cross ambient bulb must have the control case and connecting capillary located in a higher tem-
perature than the bulb.
3. On low cutout manual reset models, the temperature must increase the amount of the differential before pneumatic switch can be closed.
4. Temperature must drop 10°F (-12.2°C) before pneumatic switch can be re-closed on high cutout models.
5. Includes closed tank connector FTG13A-600R.
The performance specifications are nominal and conform to acceptable industry standards. For applications at conditions beyond these specifications, consult the local Johnson Controls office.
