7.3.4 Considerations
• The dimensions considered in the figures include the space
necessary for typical installation, and maintenance work for
operation in refrigeration mode at an outdoor temperature of
35 °C.
If the outdoor temperature is higher and if there is a
possibility of a short circuit between the inlet and outlet air,
locate the most suitable dimensions by calculating the air
flow current in comparison with the dimensions given.

• For installation in several groups, a maximum of six units (A)
one metre apart can be grouped.
• If the unit is surrounded by walls on all four sides, keep one
of the walls partially open.
• Keep the upper side open to prevent mutual interference of
inlet and outlet air for each outdoor unit.
7.3.5 Foundations
?
N O T E
All measurements are in mm.
A
Mortar housing ø100x150
B Drainage 100x20
C Anti-vibration insulation material
D Refrigerant pipes
The foundations for the installation of the outdoor unit must be
more than 150 mm above ground level.
The foundations require perimeter drainage to help drain
condensation.
When a system of condensation drainage pipes is required for
the outdoor unit, the genuine accessory DBS-TP10A should
be used. Do not fit drainage pipes or collection trays in cold
climates, as they could freeze and break.
!
D A N G E R
Drainage must not take place in areas frequented by pedestrians. In
low temperatures, the drainage water could freeze and lead to falls.
The foundations must be able to bear the weight of the whole of
the base of the unit and should be laid as shown in the diagram.

Check the front-rear line and the sides of the unit are level: there
should not be more than 10 mm difference between each side.
The foundation must be sufficiently strong to ensure that the
outdoor unit:
• Is not tilted.
• Does not produce strange noises.
• Remains secure in the event of strong winds or earthquakes.
