6.5.4 Opening adjustment of suction modulation valve:

In case of emergency, there are two ways to open the suction modulating valve manually.
It is important to follow these steps in this sequence. Use step 1 first. If this is not working, then use
step 2.
Step 1. Fully open the valve by using the dip switch on the adopter PCB.
In case of controller malfunction while the suction modulating valve and adopter PCB are
normal, turn the No. 1 dip switch ON to open the valve automatically. At the same time the dip
switch is switched, a clicking sound can be heard that the valve fully opens. If nothing will be
heard, continue to step 2.

Step 2. Fully open the valve by using an emergency magnet.
If the method of step 1 was not working, use this step to open the valve.
In case of the suction modulating valve or adopter PCB malfunction, the valve can be opened
by using an emergency magnet.
