2.4 Nameplate information
All important information for identification of the compressor is printed on the nameplate located
below the compressor oil pump.
The type of refrigerant used should be stamped on the nameplate by the installer.
The year and month of production are shown as a part of the serial number (Jan. = A, Feb. = B,
… Dec. = L).

2.5 Application range
2.5.1 Qualified refrigerants and oils
WARNING
Use of R450A and R513A refrigerants! Risk of compressor damage!
Refrigerant migration of R450A or R513A 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;
pumpdown is recommended;
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 Application Engineering for any further information.
IMPORTANT
It is essential that the glide of refrigerant blends (primarily R407C) is carefully
considered when adjusting pressure and superheat controls.

Table 2: Qualified refrigerants and oils for recharging and topping up
To recharge:
When the compressor is completely empty of oil, the amount of oil to be "recharged" is
typically 0.12 litre less than the original oil charge (oil will already be present in the system).
To top up:
During commissioning, planned maintenance or servicing, add oil so that the compressor oil
level is correct.
