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 for warranty repairs
.
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 Figures 8.1 and 8.2).
- 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).
10.2 Planning the refrigerant Return
The refrigerant circuit contains a special oil to lubricate
the outdoor unit compressor. To assist the return of the
oil to the compressor the following is recommended:
- that wherever possible the indoor unit is located
higher than the outdoor unit and,
- that the suction pipe (the largest diameter one) is
assembled with a gentle slope towards the compressor.
If the outdoor unit is mounted higher than the indoor
unit, the suction pipe must be mounted in a vertical
position. At heights exceeding 7.5 m (where this is
permissible):
• Additional oil traps must be installed at each 7.5M
interval
10.3 Connection of the refrigerant Pipes
Note!
Installation is usually easier if the gas suction
pipe is connected up first. The suction pipe is the
larger diameter one.
• Mount the outdoor unit in the required position.
• Remove the flare nuts and bonnets from the shut off
in the outdoor unit. Discard the bonnets as they are no
longer required.
• Carefully bend the installed pipe towards the outdoor
unit using a bending tool or bending spring (not
supplied).
Warning
!
Danger of breakdowns or malfunction. Danger of
damage to the refrigerant pipes.
Bend the pipe carefully to prevent kinks or
breaks.
• Cut the pipes, leaving enough extra piping hanging
over to enable the unit to be connected at the outdoor
unit valve conections.
• Flare the refrigerant pipe after first placing the flare
nut on the pipe.
• Join the refrigerant pipes to the corresponding
outdoor unit connection.
• Insulate the coolant piping correctly and separately. To
do so, cover any joints in the insulation with masking
tape or insulate any bare coolant piping with the
corresponding insulation material suitable for air
conditioning.
