*When the compressor is removed from the unit, oil level should be noted or the oil removed from the compressor should be
measured so that the same amount of oil can be maintained in the replacement compressor.
**Do not use or add standard synthetic or mineral oils to the refrigeration system. If Ester based oil becomes contaminated
with moisture or with standard oils, dispose of properly — Do Not Use!

*Suction and discharge pressures vary too greatly during Modulation Cool to use for evaluating or diagnosing refrigeration
system performance. During the Modulation Cool mode, the suction pressure will vary between 100 and 450 kPa, 1.0 and
4.5 bar, 15 and 65 psig depending upon the percent (%) cooling capacity.
**Discharge pressure is determined by condenser fan cycling.
