WARNING
Use of R450A and R513A refrigerants! Risk of compressor damage!
Migration of R450A or R513A refrigerant into the compressor crankcase could
cause low oil viscosity, which could lead to compressor damage. When using
R450A or R513A it is critical to meet the following requirements:
 maintain adequate superheat settings with a minimum superheat of 8-10K;
 no liquid refrigerant migration into the compressor at any time, especially
during standstill, during or after defrost, or after reverse mode for example
in heat pumps;
 pump-down is recommended (not for Digital units);
 the use of a crankcase heater is mandatory;
 retrofit to R450A and R513A is only allowed for compressors which are
approved for these refrigerants.
Contact your local Application Engineering representative for any further
information.
NOTE: OM(T)E & OL(T)E units are equipped with an oil separator. This separator is pre-
charged with 3.8 liter of oil.
