FIELD WORK INSTRUCTIONS
Johnson Controls’ air conditioners are designed and manufactured based on using specied
refrigerants. The applicable refrigerants are specied for each unit’s models.
Using any refrigerants besides the specied refrigerants may cause mechanical problems,
malfunction, and failure, and in the worst case, it endangers safety seriously and may cause a
re or an explosion.
Therefore, Do not charge non-specied refrigerants or any of the following in the refrigerant
system of a unit.
* Hydrocarbon Refrigerants such as Propane
* Oxygen, or Flammable Gases such as Acetylene
* Poisonous Gases
The types of refrigerants are indicated in the Installation and Maintenance Manuals, Engineering
Manuals, Service Manuals, and the specication label for each unit. Be aware that Johnson
Controls does not take any responsibility for unit failure, malfunction, or any accidents
caused by charging non-specied refrigerants or others as noted above.
