Caution!
In order to ensure an adequate load-bearing capacity of the sleeve bearings
and to ensure the service life of the roller bearings, a minimum viscosity of
7cSt upstream of the compressor is required. A suitable oil must be care-
fully selected in consideration of the operating conditions.
► The selection criteria and selection tables are summarised in the techni-
cal information "GEO Grasso VHP". This technical information forms part of
the product documentation.
► GEA Refrigeration Germany GmbH can provide assistance in the selec-
tion of a suitable refrigerator oil on request.
