3.7 — Oil Viscosity and Pour Points
The viscosity of oils used in Carlyle reciprocating compres-
sors is ISO 68 (centistoke) for all POE oils and 150 Saybolt
Seconds Universal (150 SSU or 150 SUS) or ISO 32 for
mineral and alkylbenzene oils. Using oil with a different vis-
cosity without approval from the Carlyle Engineering
Department will void the warranty.
The oils listed in Sections 3.6 and 3.7 and the viscosity
listed above can be used down to -40°F (-40°C). If your sys-
WARNING
A number of blends are not approved. Some may create a haz-
ardous situation. Carlyle requires all refrigerants used in our
compressors to be A1/A1 (low flammability/low toxicity). The rat-
ing is based on ASHRAE 34 safety standard. Not all A1/A1 refrig-
erants are approved for use in Carlyle compressors. Some of the
refrigerants or blends available are either flammable (A1/A2 or
A1/A3) and/or toxic (A1/B1 or A1/B3). Some A1/A1 refrigerants
can change ratings if contaminated. Any replacement refrigerant
must operate with the same pressure levels and temperature ranges
as the refrigerant being replaced. Do not use any refrigerant not
specifically approved in this guide unless you have obtained
approval from the Carlyle Compressor engineering depart-
ment.
