Mounting instruction - impulse lines P
L
, P
F
och P
Br
• Impulse lines should preferably be made of steel.
Inside diametre >ø 4 mm (steel tube ø 6/4)
• For P
L
other material can be used.
• Impulse lines P
L
and P
Br
are ready from factory
• Impulse lines shall be mounted in such a way that
no conden sate can low back into the multibloc.
This is especially important when P
F
is concerned.
• Impulse lines shall be mounted in such a way that
they are protected against rupture and damage.
• Impulse lines shall be as short as possible
