LA 1118CP
6.2 General requirements for heat
pump installed outdoors
The heat pump device must be installed on a suitably stable
foundation or on a permanently level, smooth and horizontal
surface. The heat pump can be installed raised by 200 mm (see
Chap. 6.3 on page 10) or level with the ground (see Chap. 6.4
on page 12).
Furthermore, the heat pump should be installed so that the air
outlet direction of the fan is perpendicular to the main wind di-
rection to allow proper defrosting of the evaporator in the event
of high wind exposure.
The cover panels on the baseplate in the machine room must
remain sealed with connection to the rear (standard configura-
tion) to guarantee optimum sound insulation and to protect the
interior of the device from small animals.
To enable this to be ensured with vertical connection of the
heat pump (optional accessories), it is essential to ensure that
all panels are fitted on the installation shaft when assembly
work is complete.
For installations on a foundation with direct contact to the

building, vibration insulation must be ensured to avoid
transmission of solid-borne noise to the building.
It must be assessed whether lightning protection is re-

quired and, if necessary, implemented.
 During the installation, the circumstances at the installa-
tion location, such as building regulations, static load of the
building, wind exposure and lightning protection, must be
taken into account.
If the installation is close to walls, it must be noted that

there may be more contamination in the intake and air out-
let area due to the air flow. For installation close to walls,
the heat pump must be able to blow out air freely for en-
ergy reasons.
 When installing multiple heat pumps, the safety zone
must be established around the entire group of heat
pumps.
To carry out maintenance work, a service area

clearances shown must be kept freely accessible. When in-
stalling multiple heat pumps, observe the service clear-

ances between the individual heat pumps.
Installation on the roof is permitted. The safety clearances

indicated must be adhered to.
When using heat pumps close to the sea, the high salt con-

tent in the air may lead to increased corrosion. The use of
heat pumps is safe from a distance of 12 km from the sea
with a maximum salt content of 3.5%.
For shorter distances, refer to the more detailed distance
calculation in the project planning manual
The device must not be exposed to corrosive or perma-

nently dusty air. (e.g. close to stables). The air containing
dust and / or ammonia can cause permanent damage to
the device.

DANGER!
Risk of death due to fire and explosion.
If there is a leakage of the propane refrigerant due to a fault,
an ignitable atmosphere can form.
 Install the heat pump in such a way that in the event of a
leakage no refrigerant can get into the building.
 Empty conduits, openings etc. that lead into the building,
shafts etc. must be fitted with an air tight seal.
Empty conduits, openings etc. that lead into the building, shafts
etc. must be fitted with an air tight seal.
If other equipment is installed inside the safety zone
components located in the safety zone must not represent an
ignition source or fire load.
NOTE
Do not restrict the air intake and air outlet area of the fan.
CAUTION!
If the heat pump takes in cooled air close to the ground, this
can cause damage or reduced efficiency.
Do not install the device in depressions or courtyards.

DANGER!
Risk of death due to fire and explosion.
Damage to the refrigeration circuit during construction work
can result in leakage of the propane refrigerant. This can
cause an ignitable atmosphere.
 Protect the heat pump from damage during installation
and other construction work.
NOTE
Structural influences must be observed for installation close
to walls. No windows or doors should be present in the area

surrounding the air outlet of the fan.
NOTE
In cases of installation close to walls, there may be more

with the
sediment in the intake and air outlet area due to the air flow.
The colder outside air outlet should discharge in such a way as
to not increase the heat losses in heated neighbouring rooms.
