NOTE: WHEN THERE ARE LIQUIDS PRESENT IN THE GAS, THE MOST EFFECTIVE
LUBRICATION OF CYLINDERS AND PACKING REQUIRES REMOVAL OF THE
LIQUIDS BEFORE THE GAS ENTERS THE COMPRESSOR.
THESE LUBRICATION RECOMMENDATIONS ARE GENERAL GUIDELINES. IF
THE RECOMMENDED LUBRICANTS OR FLOW RATES DO NOT APPEAR TO
WORK ADEQUATELY, FLOW RATES AND/OR LUBRICANT TYPES MAY NEED
TO BE CHANGED. PLEASE CONTACT THE LUBRICANT SUPPLIER FOR SPE-
CIFIC LUBRICANT RECOMMENDATIONS.
WARRANTY OF COMPONENT FAILURES WHICH OCCUR WHILE USING
LUBRICANTS WHICH DO NOT MEET THESE SPECIFICATIONS WILL BE SUB-
JECT TO REVIEW ON A CASE BY CASE BASIS.
