Scroll Compressor Replacement
The compressor manifold system was purposely designed to provide proper oil return to each
compressors. The refrigerant manifold system must not be modified in any way.
Note:
Altering the compressor manifold piping may cause oil return problems and compressor
failure.
Should a compressor replacement become necessary and a suction line filter drier is to be
installed, install it a minimum of 16 or 25 inches upstream of the oil separator tee. See
Note:
Do Not release refrigerant to the atmosphere! If adding or removing refrigerant is required,
the service technician must comply with all Federal, State and local laws. Refer to general
service bulletin MSCU-SB-1 (latest edition).
Refrigeration System
Refrigerant Evacuation and Charging
The unit is fully charged with R-410A refrigerant from the factory. However if it becomes necessary
to remove or recharge the system with refrigerant, it is important that the following actions are
taken. Failure to do so may cause permanent damage to the compressor.
Charge Storage
Due to the reduced capacity of the microchannel condenser coil compared to the round tube plate
fin evaporator coil, pumping refrigerant into the condenser coil to service the refrigerant system
is no longer an option.
WARNING
R-410A Refrigerant under Higher Pressure than R-22!
The units described in this manual use R-410A refrigerant which operates at higher pressures
than R-22 refrigerant. Use ONLY R-410A rated service equipment or components with these
units. For specific handling concerns with R-410A, please contact your local Trane
representative.
Failure to use R-410A rated service equipment or components could result in equipment
exploding under R-410A high pressures which could result in death, serious injury, or
equipment damage.
WARNING
Refrigerant under High Pressure!
System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure
before opening the system. See unit nameplate for refrigerant type. Do not use non-approved
refrigerants, refrigerant substitutes, or refrigerant additives. Failure to recover refrigerant to
relieve pressure or the use of non-approved refrigerants, refrigerant substitutes, or refrigerant
additives could result in an explosion which could result in death or serious injury or
equipment damage.
