MULTI-BLOC VDG20… SKP75/15
- Impulse lines are mounted from factory
- Should any of the impulse lines be changed should it be made of steel.
Inner diameter > ø 8 mm (steel tube ø 10/8)
- Impulse lines must be mounted so that condensate cannot enter into
the multi-bloc. This especially applies to pC.
- Impulse lines must be mounted so that they are protected against rupture
and damage.
- Impulse lines shall be as short as possible.
