6.3. Switching on
1. The unit is switched on by means of ON-OFF switch.
•
position „0“ - the unit is off
•
position „I“ - the unit is on (the switch illuminates)
2. Suction circuit - option and switching on
You can choose left or right suction circuit. It is possible to use both suction circuits at the same time.
3. Select the respective required value by regulator valve.
Vacuum is increasing by turning round of a regulating vent with the sun. Value of vacuum is displayed only if filtering
perimeter is closed, e.g. by cranking the end of the filtering hose.
Vacuum-meter scale is into bars.
-1bar = -100 kPa = -100% vacuum
6.4. Functional examination of suction unit
6.4.1. Inner suction circuit
•
turn the suction unit on
•
cover the connector (1) on the suction unit by your finger
•
turn the vacuum regulating vent with the sun till it stop
•
maximum vacuum value must be displayed on the vacuum-meter (see point “Technical data”)
Status of components and leakage inside of suction unit is controlled by the test.
6.4.2. Outer suction circuit
•
turn the suction unit on
•
crank or cover free end of the suction hose (11) by your finger
•
turn the vacuum regulating vent with the sun till it stop
•
vacuum-meter must display maximum value of vacuum (see point “Technical data”) after
some time (it depends of the secret vessel volume)
Status of components and leakage inside of suction unit outside its own body is controlled by the test.
