Assembly Of The Outdoor Unit; Installation Variant For The Outdoor Unit - iDM iPump A 3-11 Technical Documentation Installation Instructions

6 .2. Assembly of t h e ou t d oor un it
The outdoor unit consists of the ventilator, the expan-
sion valve and the evaporator.
The refrigerant lines between the internal and the
outdoor unit must be build on site. the refrigerant
lines are available as an accessory. The hot gas- and
the liquid line must be insulated separately.
Installation site preparations
Take the following points into account when installing
the outdoor device:
- The maximum pipe length between the external-
and the indoor unit may not be more than 20 meter
(in one direction)
- For difference height between indoor- and outdoor
unit see page 16
- The installation site must be selected such that no
noise interference can occur (do not install close
to bedrooms, keep distance from neighbours),
hedges and bushes can absorb noise
- A frost-proof connection of the condensation run-off
is required
- Unhindered air fl ow must be possible (install at
least 20 cm above the expected snow depth)
- The minimum distances, mentioned on the fol-
lowing pages, must be observed
- The inlet air must be free of impurities such as sand
and caustic materials such as ammonia, sulphur,
chlorine, etc.
- The outdoor unit must be installed on a rigid, solid
construction
- When installing at windy locations (e.g. on a roof),
the alignment of the machine must be selected
such that the prevailing wind direction is normally
facing the air inlet direction of the external device

If the alignment is not possible at very windy loca-
tions, additional wind protection can be installed, e.g.
a hedge.

run-off
In this variant, the outdoor unit of the iPump A 3-11 is
mounted on two bases. The refrigerant lines and the
condenser run-off are routed between the two bases
and must be connected to the outdoor unit. The load
capacity of the base must be given.
