Adjustment required. The TXV will need to be closed to raise the superheat post
retrofit. Also, it is recommended to change to R-22 or equivelent power element.
Change driers. This is a routine system maintenance practice.
Review guidelines from compressor manufacturer. For low temp refrigeration, someform of discharge temperature management (head fan/liquid injection) might berecommended.
Adjust set points. Many refrigeration control systems and methodologies rely onpressure-temperature relationship of specific refrigerant for proper operation.

R-22 to XP40 (R-449A)

Lubricant needs to be changed to POE. Most compressor manufacturers recommend
flushing to a maximum of 5 wt% residual mineral oil in the system for effectiveperformance. If system performance is not compromised, residual mineral oil in therange of 5 to 10% is acceptable.
Change critical elastomeric seals. R-22 and, to a lesser extent, R-22-containing
refrigerant blends, interact relatively strongly with many elastomers, causing
significant swelling and often, over time, a measurable increase in hardness.
Opteon™ XP40, like other HFO or HFC refrigerants, does not have as strong of aneffect on elastomers commonly used as seals in refrigeration systems. Without
replacement, the seals can deform which will result in leaks.
Properly sized R-22 valve bodies and power elements are compatible with R-449A.
Post retrofit, minor adjustments to the spring pressure of the valve will likely beneeded to reach target evaporator superheat.
Change driers. This is a routine system maintenance practice.
