Assembling the hose nozzle with union nut
(PC 510/610 NT):
➨
Take the hose nozzle with attached compression fer-
rule and union nut out of the catchpot and put onto
inlet connection.
➨
Tighten the union nut by hand until you can feel the
stop. Then tighten an additional 1/4 rotation with an
open-ended wrench (size 17mm) for final installation.
Connection of components at the controller
At the rear side of the pumping unit and at the
rear side of the second controller (only PC
520/620 NT) are VACUU•BUS jacks for con-
nection of accessory components: in-line valve
/ coolant valve / external pressure transducer
/ external venting valve / level sensor / emis-
sion condenser Peltronic etc.
+
Plug the VACUU•BUS lines of accessory
components into the VACUU•BUS jacks. Do
not apply off-axis forces when assembling
or removing plug connections! Observe cor-
rect orientation of the plugs.
Depending on technical version the connec-
tions of the VACUU•BUS cables are equipped
with a nib.
➨
When connecting the VACUU•BUS connec-
tions to the rear side of the controller position
the nib (1) of the VACUU•BUS connection in
the notch (2) of the controller connections.
