4.5 Mounting of silicone tubes
PD12 is equipped with tube bridges and tube locks. The tube locks ensure that the mounted tubes do
not slide through the dispenser head when running.
The tube bridge retains the tube and performs the necessary pressure on the tubes.
Open the dispenser head by tipping each of the two locking pins up and lift the tube bridge

Mount the correct tube lock (1) on its dowel pin and place the tubes.
It is important that the tubes are situated in the two notches (2+3).
The Y-connector must be situated at the opposite side of the tube lock.
Now mount the tube bridge in its tracks and engage the two locking pins.

NB! Never leave the dispenser mounted with tubes overnight.
At least tip the locking pins up in order not to retain the tube in pressure.
