Oil filter
You must replace or clean the oil filter every time the lubricating oil is changed.
•
The fineness of the filter is 7 µm and its resistance, when clean, is around 0.2 bar.
•
The maximum resistance must
•
NOT exceed 2.0 bar.
At an oil pressure of around 1.8 bar, the compressor shuts down.
•
With frequency converter operation, shutdown occurs at approx. 0.5 bar (o) and
•
another switch is required.
A strap spanner or similar should be used for removal purposes.
•
To install the new oil filter, the sealing ring should be lubricated sparingly and the
•
filter screwed in until it is hand-tight.
CAUTION!
•
Oil may escape when the oil filter is removed.
Do
•
NOT
change the oil filter while the oil is hot! Danger of scalding!
•
Example: Oil filter
Example:
Oil cooler
Oil temperature controller
Oil cooler
The oil cooler cools the lubricating oil during operation and works in conjunction
•
with a temperature controller to ensure a constant oil temperature.
The standard oil temperature is approx. 55°C.
•
The flow of cooling air is caused by a directly driven fan impeller for the compres
-
•
sor.
The cooler fan impeller is a component that rotates at a high speed and must
therefore be adequately protected against contact occurring with it at all times.
CAUTION!
Risk of injury!
The oil temperature may reach 95°C. This mainly depends on the ambient condi-
•
tions, operating data and how soiled the cooler blades are. Please observe the
maintenance schedule.
Depending on how soiled the blades are, the cleaning intervals may deviate from
those stated on the maintenance schedule.
The cooler blades must be cleaned after every 4000 op. hrs/6 months.
