THE PIPE RUN
When installing the pipe run in your home during the building period, this should be done while the walls are still
open and all possible obstacles (water pipes, electrical runs etc.) are visible.
Note! Remember that branch pipes to inlet valve should never point downwards (fig. 8.2).
Where pipe runs are not visible (inside walls and floors) you will sometimes have to go through joists in the floor.
This must be done according to fig. 8.3 - 8.5 and 8.8.
Note! The low voltage wire must follow an uninterrupted route from inlet to inlet and all the way to the power unit.
Strap or tape the wire to pipe (fig. 8.6 and 8.7).
Pipe runs in existing homes should be installed in closets/cupboards, subordinate rooms, loft space or built-in in
corners. (If necessary, use pipe straps as shown in fig. 8.6).
When going through existing walls/floors, drill an inspection hole to verify that the wall/floor does not contain any
electrical conductors or water pipes. Use a piece of steel wire and a flash light to look for obstacles. See fig. 8.10
