2.2.1 Mounting the Piping
The piping must be mounted to a firm base (wall etc.) using special brackets. Recommended
pitch between brackets is 1 to 2m to prevent vibrations of the piping during operation. The
piping must not be in contact with the base. The holes through walls and bases must be
insulated and filled with PU foam so that the piping is not in contact with the wall, concrete etc.
Holes under the ground must be waterproofed to prevent the humidity and water from
penetrating the building.
2.2.2 Horizontal Parts of the Vapour line
The horizontal parts of the
vapour piping
must be descended by 1:100 toward the coolant flow
in the heating mode (always in direction from the outer toward the inner unit).
2.2.3 Vertical Parts of the Vapour line
In the case the piping is vertical and the coolant ascends (typical for cases where the outer unit
is lower than the inner one), the piping must be equipped with oil traps. For typical installation
see picture below.
