10.1. Installation frequency and height
The locations of the wall inlets should allow the entire area to be cleaned
using a standard length suction hose assembly (8 or 10 metres). Use a
thread or a piece of electric wire proportioned to the scale of the design
and the length of the suction hose for planning.
The thread will help you to view the reach of the suction hose, and enable
you to dene the locations of the wall inlets. Locate the wall inlets so
that the suction hose will reach all areas, and the area cleaned using
one wall inlet is maximised. Consider the reach of the suction hose in
spaces with furniture: the user may need to go around the furniture when
cleaning. Lengthening the suction hose assembly beyond 10 metres will
decrease the suction power and make it more difcult to manage the
hose, and may cause the turbine thermal protection to turn the central
unit off repeatedly.
Sometimes, for example in hotels, wall inlets may be located on both
sides of the corridor in order to avoid the hotel visitors needing to walk
over suction hoses drawn accross the corridors. Also avoid crossing
passage and transportation routes in public spaces and storages.
The recommended installation height for the wall inlet is level with the
light switch. This will remove the need for bending over when attaching
the suction hose to the wall inlet. Aesthetically the wall inlets should be
at the same height.
10.2. Installation locations of the wall inlets
The wall inlets can be installed in almost any wall material, as long as
the diameter of the dust pipe within the wall (44 mm, or 51 mm in sleeve
joints) is considered. Flush mounting to slab walls requires a minimum
beam strength of 67 mm. The most commonly used wall types are:
a) Lightweight partitions of wood, chipboard, or plaster board
b) Coated masoned brick walls
c) Clean-masoned brick walls
d) Walls cast on-site
e) Element walls.
Installation is more expensive in the latter wall structures. The installation
of the wall inlets or reservation for the wall inlets must be performed in
the manufacturing stage of the element.
The walls in restaurant dining rooms and auditoriums are often so far
from each other that the wall inlets must be installed on the oor or xed
furniture, such as the walls of buffet tables or the plinths of various xed
pieces of furniture. Avoid installing wall inlets on perimeter walls.
When installing the piping and the wall inlets in storage facilities, air-
raid shelters, industrial facilities or other spaces where the piping can
be visible, the pipes should be surface mounted using separate surface
mounting equipment.
10.3. Wall inlet models
For professional use, use the steel wall inlets (RST). The plastic wall
inlets are only intended for domestic use. The plastic wall inlet cover is
difcult to open in the Manta system if the system is being used. The
wall inlet may also be damaged.
For public spaces, we recommend using lockable wall inlets. Wall inlets
without locks may be used in other spaces. The RST wall inlets are also
available stoved white (RAL 9010, glossy) upon request.
