suction line trap

[nvr2old]

Hope this is correct forum. We're installing a split wine unit for wine room. The refrigerant piping instructions call for a trap in suction line half way up between condenser and evaporator. The evaporator is 20' above condenser. What is the purpose of this trap? I've seen traps in suction line when condenser is above evaporator.

Were is the compressor in relation to the evaporator?

If I recall correctly it is for proper oil return. With out the traps they oil settles in the wrong locations and will cause damage.

condenser/compressor is 20' below evap and 45' total refrigerant line length.

Just thought I would point this out as it seems to have been missed.
