5.2.2 Setting up Split System
The split system consists of an outdoor unit and a hydro-module or combination hydro-module.
Depending on the power and model, the outdoor unit has one or two fans and thus their in-
stalled size differs (→ 1 Model range, p.
In general, the following points should be remembered regarding the distance between outdoor
unit and hydro-module or combination hydro-module when using the split system:
● If the length of the coolant pipelines is greater than the pre-filled connection dis-
tance of the device (depending on the model 10, 15 or 30 m;
(split systems), p. 16), the quantity of additional coolant stated in the technical
data should be added.
● The maximum length of the coolant pipelines between hydro-module and outdoor
unit is 15 or 30 m, depending on the model
p. 16). The value should not fall below this.
● The minimum length of the coolant pipelines between hydro-module and outdoor
unit is 3 m and not less than that.
● The maximum difference in height between hydro-module and outdoor unit is 20
or 30 m (→ 4.6.3.3 Technical data (compact systems), p.
model. The value should not fall below this.
● The wall thickness of the copper tubes for the coolant pipelines must be more than
0.8 mm.

5.2.2.1 Assembly conditions for outdoor units

The assembly conditions for the outdoor unit are as follows:
● The outdoor unit has only been developed for outdoor installation and must not be
installed indoors.
● For condensation water drainage in defrosting mode, drainage is recommended via
a drain pipe to the frost-free ground with gravel fill
unit, p. 92).
● Maintain the minimum distances
p. 91).
● The heat emission of the outdoor unit must not be impeded by additional protection
devices such as awnings or such.
● No objects should be put up that can cause short- circuiting of the exhaust air.
Even when using multiple outdoor units (e.g. in case of heat pump cascades),
avoid any air flow short-circuiting on the facing air
unit, p. 92).
● The operating sound of the outdoor unit must not cause any stress to the user or
to neighbours. Air-to-water heat pumps may in certain countries or regions, require
permission. All provisions regarding noise valid at the location must be taken into
account (→ 5.2.1 Acoustics, p.
● In addition, use vibration-damping rubber buffers for isolation.
● If installing outdoor units near to the sea, in regions with a high content of sulphur
or at sites where large quantities of oil (e.g. machine oil, etc.) are present, its oper-
ating life may be shortened.
● The outdoor unit is to be installed on a concrete foundation or a stable ground
frame e.g. on the outer wall of a building, aligned horizontally and bolted down
(ø 10 mm).
● In the case of installation locations experiencing strong winds e.g. on building roof-
tops or between buildings, the outdoor unit must be additionally secured to the side
of the building to prevent tipping over (e.g. by bracing).
