Issue:
Can I convert the RTAF from R134a to R513A?
Resolution:
Replacing R134a with R513A is a relatively easy process.
-
What parts need to be changed out?
- Just refrigerant
-
Different lubricant / oil?
- Same oil
-
Does the refrigerant system need to be cleaned/flushed before putting new oil and R513A refrigerant?
- No, R513A is compatible with R134a
-
Do we have a UC800 “flash” for R513A, or does the Trane technician have to manually change the settings/safeties?
- Yes, the controls configuration will need to be updated to show R513A – slightly different properties and control algorithms.
