the glass. DO NOT OVERFILL SUMP. The crankshaft will dip into the oil, churn
it, and make it difficult to pump and to control the proper level. (After the
machine is running, it may be necessary to add oil to bring up oil level to one-
half the height of the sight glass; but it must never exceed two-thirds height
while running.)

For compressors with separate oil sump, fill sump with lubricating oil as
required.
Priming - Main Lube Oil System
BE SURE THE OIL SYSTEM FROM THE LUBE OIL PUMP THROUGH THE COOLER
AND OIL FILTER IS FILLED WITH OIL.
Remove cover doors and operate the prelube pump to verify that oil is dripping from the
bearing and crosshead positions.
Compressor Prelube
See Section 4 “Compressor Prelube” for the prelube requirements for starting the compres-
sor.
Force Feed Lubricator Adjustment
Be sure that the force feed lubricator pumps are set at the break-in rate shown on the force
feed lubricator data plates. Reference Section 1 for data plate location and legend illustra-
tion. Indicators on the distributor blocks show the rate at which a block is cycling. To adjust,
loosen locknut and turn the feed regulator (plunger stroke adjustment screw) on the pump at
the lubricator box, until the indicator strokes at the proper rate, seconds per cycle. Refer-
ence Section 5 lubricator box chain sprocket illustration for component legend. Re-tighten
locknut. Run at this break-in setting for the first 200 hours of operation. The lubricator cycle
time may then be increased to the normal operating rate. Reference Section 4 for more
information on force feed lube rates.
Compressor Re-Application
IF ANY OF THE CONDITIONS LISTED BELOW CHANGE, CONSULT YOUR PACKAGER
AND/OR ARIEL FOR ANY HARDWARE AND/OR DOCUMENTATION CHANGES
THAT ARE REQUIRED. PERFORMANCE, OPERATING PRESSURES AND
LUBrication RATE MUST BE RECALCULATED. A TORSIONAL VIBRATION
ANALYSIS IS RECOMMENDED.
