3. Installation

1. Connect the pump group, including the insulation, to the existing pipe installation.
2. Tighten the fixations by hand.
3. Mark the bottom and the middle of the case. Subsequently remove the compact distributor again, according to ISO.
4. Drill holes into the wall according to the markings and insert wall plugs.
5. Mount the bottom case by using the screws and washers supplied.
