Recover Refrigerant
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 in
R-404A. See Thermo King Parts Manual for part number.
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.
When servicing Thermo King R-404A unit, use only those service tools certified
for and dedicated to R-404A refrigerant and Polyol Ester compressor oils.
Residual non-HFC refrigerants or oils will contaminate R-404A systems.
