5. Unit’s operation
5.1. Starting and stopping the unit
•
The unit can be started by pressing the start button located inside the control panel box.
•
Press the stop button to stop the unit.
5.2. Monitoring devices
The unit is equipped with a pressure gauge to monitor the clogging of the main filter (stage 3). Maintenance of
the prefilter (stage 1) is normally required less often and as a consequence is not monitorized by the pressure
gauge. Verify conditions of the prefilter when doing maintenance on the main filter.
From the gauge shown in Figure 13 you can have the following information:
a) Figure 13a the gauge needle near to zero indicates that there is no passage of air and this may be due to two
different causes:
-
the oil mist collector is not in operation
-
the pre-filter is clogged
-
b) the position b (with needle normally between .1 and .2) is with clean filters and oil mist collector in function
c) the position c (with a needle on the orange or red) indicates that the final cartridge is clogged
13 a) collector OFF or prefilter
clogged
13 b) with clean filter at first start
13 c) final cartridge clogged
Note
In some extreme cases the prefilter can require shorter maintenance intervals than the main filter.
One example is an application with presence of large amounts of metallic dust. In these cases make
sure that verify conditions of the prefilter more often than indicated on the maintenance section table
Upon request the mist collector can be equipped with additional monitoring devices. Please contact LNS Italia
sales department for additional information.
