IMPORTANT:
- T he insertion of each additional 90°
bend with a diameter of 60/100 reduces
the available section by 1.5 meters.
- T he insertion of each additional 90°
bend with a diameter of 80/125 reduces
the available section by 2 meters.
- E ach additional 45° curve installed
reduces the available length by 1.0
metres.
- During assembly it is important to make
sure that the kit with axial pipes. (1) is
positioned horizontally.
NOTE
Before connecting accessories, it is
always advisable to lubricate the internal
part of the gaskets with silicon products.
Avoid using oils and greases.
