Trane Thermo King V-520 RT SPECTRUM 50 Installation Manual page 6

At Thermo King, we recognize the need to preserve the environment and limit the potential harm to the ozone layer that
can result from allowing refrigerant to escape into the atmosphere.
We strictly adhere to a policy that promotes the recovery and limits the loss of refrigerant into the atmosphere.
In addition, service personnel must be aware of Federal regulations concerning the use of refrigerants and the certification
of technicians. For additional information on regulations and technician certification programs, contact your local
THERMO KING dealer.
WARNING: Use ONLY Polyol Ester based refrigeration compressor oil (TK P/N 203-515) in R-404A and R-134a units.
DO NOT use Polyol Ester based oil in standard Thermo King units.
DO NOT mix Polyol Ester and standard synthetic compressor oils.
Keep Polyol Ester compressor oil in tightly sealed containers. If Polyol Ester oil becomes contaminated with moisture
or standard oils, dispose of properly—DO NOT USE!
WARNING: When servicing Thermo King R-404A and R-134a units, use only those service tools certified for and
dedicated to R-404A or R-134a refrigerant and Polyol Ester compressor oils. Residual non-HFC refrigerants or oils will
contaminate R-404A and R-134a systems.
Thermo King condenser units and remote evaporators are shipped with a 35 kPa (5 psi) holding charge of Nitrogen.
This holding charge may be safely vented into the atmosphere.
CAUTION: SEVERE COMPRESSOR DAMAGE will result from operating the unit before completing the installation
which includes: installing the components, releasing the holding charge, connecting refrigeration lines, leak testing,
evacuation, clean-up and charging of the system with the proper amount and type of refrigerant.
