Honeywell EkoFlush-K572 User's Operating Manual page 6

6.11 Check the oil level in the compressor sight-glass and refill if necessary. The level of the oil must
be between those two lines, indicated in the picture below.
WARNING! Any claim for malfunctioning caused by lack of oil won't be accepted!!
6.12 Connect the front panel of the EkoFlush K572 to the circuit to flush, as follows:
inlet into the flushed circuit to "IN"
-
outlet from the flushed device "OUT"
-
The ends of the hoses with the valves must be near the flushing unit.
IMPORTANT
Whenever possible, in order to ensure easier flushing, please connect the inlet to the circuit to
be flushed in higher position than the outlet: gravity helps the cleaning process.
