SERVICING
PVE oils maintain a consistent viscosity over a large temperature range which aids in the oil return to the compressor; however,
there will be some installations which require oil return traps. These installations should be avoided whenever possible, as
adding oil traps to the refrigerant lines also increases the opportunity for debris and moisture to be introduced into the system.
Avoid long running traps in horizontal suction line.
NOTE: If line set is installed on the exterior of an outside wall, similar installation practices are to be used.
