NOTE
Compressor oil
: The compressors are supplied with CARRIER POLYOLESTER (POE) oil. The pres-
ence of a sticker indicates that the oil change has been correctly carried out in out Carrier Transicold
plant. Oils of PAG type are strictly incompatible with the operation of our units. Never use an oil other
than that approved by Carrier.
On request, Carrier can analyze your compressor oil. To do this, a small drum is sent with a label
attached. On the label, indicate: the type of compressor, the lapse time or mileage since the last oil
change, the type of Carrier equipment, and the date of initial operation.
