Oil filling

Only charge with fresh, unused oil.
The vacuum present in the product before pressure compensation may be uti-
lised for charging the package with oil. A separate oil charging pump is required
after the pressure compensation and for refilling with oil.
The stop valve oil drain connection or oil filling (90) must be connected with the
oil charging tank.
Before filling with oil, switch the valves to the operating position.
Open the stop valve (90) until the oil level has reached the top third of the sight
glass assembly in the compressor crankcase.
When charging with oil for the first time, oil must also be charged via the oil prelu-
brification valve on the reciprocating compressor.
The installation and maintenance instruction for the reciprocating compressor
which is part of the product documentation is to be observed for this.

GmbH.
Notice
Due to the use of selected components, the refrigerator oils tend to absorb
more moisture.
► Therefore, when charging a product, the oil should be allowed to come
into contact with air for a short time only. The contents of an opened drum
have to be used up within one working day, provided the drum is properly
closed between charging.
