All fuses must be switched on in order to switch the META Tower on.
Main switch
20.1
must then be pressed into the „I“ position. When the
mains power supply is present, the switch illuminates green and the LED
(Abfluss/Drain) flashes for a short time.
To switch the compressor on, turn pressure switch
20.3
into the
„I“ position.
The compressor now starts up and is controlled by the pressure switch
that stops it when the pressure in the tank reaches the switch-off pres-
sure (7 bar); the compressor starts again when the switch-on pressure
(5 bar) is reached.
If the compressed air tank is pressurised, the operating pressure can
be adjusted using pressure controller
20.4
: Turn the adjustment screw
clockwise to increase the pressure and anticlockwise to lower the pres-
sure. The current pressure can be read from pressure gauge
20.2
. Once
the required air pressure is reached, press the adjustment screw down-
wards to lock it.
While the pressure is being built up, open condensation drain valve
20.5
on the tank and catch the condensation (if present) in a collection
tank. Then close it again.
The safety valve is set to 10 bar. The safety valve must be
inspected when operating the compressor for the first time.
The safety valve is not permitted to be used to drain the
pressure tank, as this may impair its functions.
Suction machine
In order to start the suction machine, a suction hose must be picked up
from the hose support on the dental unit or the rinsing basin rinsing
system (in a wet suction system) must be actuated.
Check that all hose connections and suction line connections are leak-
tight.
The suction machine is stopped again by hanging the hose back into the
hose support and after a run-on time of approximately 60 seconds.
