• For pipework exiting from the right hand side and
bottom of the unit extend the pipework through the
relevant knock out before hanging unit (see section
9.3.6).
• For pipework exiting from the left of the unit, make
the connections at the rear of the unit first before
hanging the unit (see section 9.3.6).
Note!
The flare connections should be, where possible,
accessible to allow leak test and future access.
9.3.6 Installation of the Indoor Unit Body
• Check that the installation has been carried out
correctly and that there are no leaks (see section 12.1).
• Securely hang the indoor unit body onto the upper
notches of the mounting plate. Briefly move the body
from side to side to verify that it is secure.
• Lift the body up slightly from underneath, press it
onto the mounting plate and then lower it vertically.
The body will fit into the lower supports on the
mounting plate.
• Check that the indoor unit is properly secured.
• In the event that the body does not slot into the
supports properly, repeat this process.
• Do not use excessive force as this may damage the
fixing lugs, ensure that the pipework is not trapped
behind the unit.
10 Installation of the Outdoor Unit
10.1 Selecting the Assembly Location
Warning
!
Outdoor units must be placed in accessible areas
for subsequent maintenance and repair
operations. Vaillant will not be responsible for
any costs derived from incorrect positioning that
prevents easy access.
Danger of personal injury and material damage
from explosion!
Install the unit away from inflammable gasses
or liquids or easily combustible substances and
free from thick dust formation.
Danger of personal injury and material damage
from collapse!
Ensure that the ground is smooth and level
and can withstand the weight of the outdoor
unit.
Warning
!
Danger of corrosion.
Do not install the unit near to corrosive
materials.
- The outdoor unit can only be mounted outdoors, never
inside a building.
- Do not install the unit in such a way that the air
discharge affects the air inlets of premises nearby.
- If possible avoid direct sunlight.
- Ensure that the ground has sufficient rigidity to avoid
vibrations.
- Ensure that there is sufficient space to observe the
minimum distances (see Figure 8.1).
- Ensure that neighbours are not disturbed by draughts
or noise.
- If the premises are rented obtain the owner's consent.
- Comply with local regulations: there are considerable
differences dependant on the area.
- Leave enough space to fit the condensed water
drainage pipe (see section 10.4).
