How split systems work
3. How split systems work
An air/water heat pump extracts thermal energy from the
ambient air (low temperature) and transmits it together with
electrical drive energy in the form of useful heat (higher
temperature) to a heating and/or DHW circuit.
The heat pump consists of separated circuits linked togeth-
er via heat exchangers:
►Heat source circuit (extracting heat)
►Refrigerant circuit
►Heat sink circuit (supply of heat for room heating and/
or DHW)
Outdoor air is a heat source that is available everywhere
in unlimited amounts and can be utilised without approval.
It is especially suitable for retrotting.
A split system consists of an indoor unit and a separately
installed outdoor unit. The outdoor air is routed through the
outdoor unit by means of a fan. The indoor and outdoor
units are connected through refrigerant lines.
Due to the defrosting mode integrated into OCHSNER air/
water heat pumps, the system also operates awlessly at
temperatures below -15°C.
For air/water heat pumps, the most e󰀩cient and therefore
most common operating mode is bivalent parallel opera-
tion.
Due to the integral defrosting mode, the monovalent op-
erating mode is also possible. As the heating output of an
air/water heat pump at an outdoor temperature of +15°C
is approx. triple the heating output at -15°C, such systems
are vastly oversized for operation in spring and autumn
and therefore not recommended.

17 Air vent valve
The bu󰀨er tank and the DHW tank with heat exchanger
are arranged on top of each other and can be separated
for handling.
The appliance is tted with a plastic foam outer casing and
a removable front panel.
All hydraulic connections are at the top.
Condenser:
The condenser takes the form of a plate heat exchanger.
The plate heat exchanger is built of stainless steel and
insulated on all sides against condensation and heat loss.
DHW tank
The steel tank is tted internally with a special direct enam-
el and a sacricial anode. The anti-corrosion anode with
wear indicator protects the inside of the tank against cor-
rosion.
The heating water heated by the heat pump is pumped
through an internal indirect coil into the DHW tank. The in-
ternal indirect coil transfers the absorbed heat to the DHW.
Bu󰀨er tank
The steel tank serves to hydraulically separate the ow
rates of the heat pump and the heating circuit. The heating
water heated by the heat pump is transported to the bu󰀨er
tank by the bu󰀨er charging pump. When there is a demand,
the heating water is supplied to the heating circuit by the
integral heating circulation pump.
Multifunctional assembly (MFA)
The multifunctional assembly switches between heating
circuit and DHW circuit. It includes the following compo-
nents:
- High limit safety cut-out
- Air vent valve
- Flow meter
- System pressure sensor
- Electric auxiliary heater
Note
At low outdoor temperatures, the appliance oper-
ates in bivalent-parallel mode.
4.3.2 Outdoor unit
The outdoor unit is intended to be installed outside. The
outdoor unit is designed as a split evaporator. The indoor
unit is connected to the outdoor unit with refrigerant lines,
along with electrical control and power supply cables.
Evaporator:
The evaporator is part of the outdoor unit and consists of
copper pipes in a set of aluminium ns.

12 www.ochsner.com | 00_200_202_08_02_002-EN
Device description
Note
With an air/water heat pump, frost may form on
the evaporator ns of the outdoor unit, depending
on the air temperature (below approx. +7°C), air
humidity and the operating point. The evaporator
ns are automatically de-iced again in cyclical de-
frosting mode of the heat pump.
Fan:
The outdoor air is drawn through the evaporator by a quiet
fan.
Compressor:
The fully hermetically sealed compressor is designed for
high e󰀩ciency heat pump applications.
4.3.3 Heat pump control unit
The OTS heat pump controller includes software capable
of automatically controlling heat pump heating systems
with a cooling function as well as DHW heating.
All the settings required in the system can be made using
the controller on the heat pump or via the app.
The OTS controller can control the following system circuits
and heat generators:
►1x direct circuit (heating and/or cooling)

ENGINEERING OF A
SPLIT SYSTEM
Note
The machine-specic information on engineering
and preparation can be found in this document‘s
machine-specic engineering and preparation sec-
tion.
Note
Plan the installation sites for the outdoor and indoor
units so that the refrigerant lines are as short as
possible and the pipes are routed as straight and
simply as possible.
Note
If the pipe liner is laid empty, inserting the refriger-
ant lines afterwards will be di󰀩cult if not impossible,
depending on the position layout of the connection
line.
»
When laying refrigerant lines in the ground,
schedule the work so that the pipe liner can
be laid together with the pre-inserted refrig-
erant lines in the trench between the outdoor
and indoor units.
Note
Observe national and regional regulations regard-
ing the requirement for and design of lightning
protection.
Note
Observe the machine-specic limits of use.
5. Outdoor unit
5.1 Installation location
The outdoor unit is intended to be installed only out of
doors. Please note the following with regard to the instal-
lation location of the outdoor unit:
►Select the outdoor unit installation location so that the
appliance can be safely accessed from all sides all
year round.
►Installation in a hollow or ditch is not permissible (cold
air pocket).
►High wind loads on the outdoor unit can cause
problems with defrosting in defrosting mode. Avoid
installation in an open and exposed location with high
expected wind loads (e.g. at roof of a house in a
raised location).
►Select an installation location where the appliance is
on the side of the building facing away from the wind
(“leeward side”).
Material damage
The air ow through the evaporator must not be
obstructed by surrounding buildings. A reduced air
ow rate can lead to loss of e󰀩ciency in the system.
»
Observe the machine-specic requirements
regarding the installation location.
Material damage
The intake air must not be contaminated with corro-
sive substances (ammonia, sulphur, chlorine, etc.).
This can destroy machine components.
5.2 Minimum clearances
Observing the specied minimum clearances for the out-
door unit ensures:
►Correct installation of the appliance
►That it operates fault-free
►Ability to carry out maintenance on the appliance
»
Observe the machine-specic minimum clearances.
5.3 Foundations for the outdoor unit
A permanent foundation is required beneath the outdoor
unit. The foundation must meet the structural requirements
of the outdoor unit.
»
Provide frost-free drainage (e.g. a gravel bed con-
nected to a drain) for condensate that forms on the
outdoor unit.
»
Where refrigerant lines are to be laid in the ground,
ensure correct positioning of the pipe liner when lay-
ing the foundations.
»
Use rigid underground sewer pipes (with a smooth
inner surface) for the pipe liner. We recommend using
sound-insulated underground sewer pipes.
»
Ensure that the outdoor unit is adequately secured,
with regard to the wind load occurring at the installa-
tion location.
»
When constructing the foundations, observe the ma-
chine-specic guidelines.

00_400_200_202_02_split_Planung_Errichtung-EN | www.ochsner.com 15
Outdoor unit
CAUTION: Risk of slipping
If drainage for condensation is inadequate, ice can
build up in winter in the area around the outdoor
unit.
»
Ensure drainage for condensation is su󰀩cient
even at low temperatures.
»
Ensure that no ice is formed, especially on
paths and entrances around the outdoor unit.
Note
Insulation used beneath the soil must be of a
closed-cell material construction. Otherwise, the
thermal insulation value of the material will be im-
paired.
5.4 Sound
Please note the following with regard to sound emissions
from the outdoor unit:
►Avoid installing on reverberant ooring.
►Avoid installing between two building walls or in cor-
ners. Walls can increase the noise level.
►Avoid placing the unit directly below or next to rooms
that are sensitive to sound (e.g. bedrooms).
Note
Plants and cultivated areas around the outdoor
unit, subject to minimum clearances, can reduce
its noise level.
Note
The maximum permitted sound levels are partly
subject to legal limitations.
»
Observe all applicable national and regional
regulations and provisions.

Refrigerant lines
6. Refrigerant lines
6.1 Preparing the refrigerant lines
Note
Only OCHSNER customer service or authorised
OCHSNER customer service partners may con-
nect the refrigerant lines to the indoor and outdoor
units.
Note
If the appliance, the refrigerant lines, the pipe
xings and the wall conduits are not installed cor-
rectly, structure-borne sounds can be transmitted
to the building.
»
Ensure that the refrigerant lines are in-
stalled in a way that ensures insulation from
structure-borne noise. The system installer
carrying out the work is responsible for this.
»
Never lay the refrigerant lines in a bricked-in
sleeve tube. Noise transmission to the living
space is unavoidable when bricked-in sleeve
tubes are used, due to the resonating body
e󰀨ect.
»
Use insulating refrigerant pipe clamps for ver-
tical installation of the refrigerant lines. The
distance between the refrigerant pipe clamps
must not exceed 1.25 m.
Material damage
Thin-walled pipes are at risk of bursting.
»
Only use copper pipes suitable for refrigerant
(EN 12735-2).
Material damage
Dirt and contamination in the refrigerant lines can
result in a clogged expansion valve or compressor
damage.
Incorrect or premature opening of the refrigerant
connections can allow dirt and moisture to enter
the refrigerant circuit.
»
Only use copper pipes suitable for refrigerant
(EN 12735-1).
»
Do not open the connections on the indoor
and outdoor units.
»
Ensure that no dirt enters the refrigerant
pipes.
Note
Systems with incorrectly sized refrigerant pipes
cannot be commissioned.
»
Observe the machine-specic dimensions for
the refrigerant pipes.
The refrigerant connections (suction gas and liquid lines)
on the indoor and outdoor units are supplied soldered
closed.
Note
Appropriate copper pipes for refrigerant lines are
supplied sealed at both ends and lled with nitro-
gen.
Please note the following with regard to routing of the re-
frigerant pipes:
»
Keep the distance between the indoor and outdoor
units to a minimum to prevent heat loss from the re-
frigerant pipes.
»
Select the installation sites for the indoor and outdoor
units so that the maximum permissible line lengths
and height di󰀨erentials are observed.
»
Avoid routing the lines in the vicinity of rooms that are
sensitive to sound (e.g. bedrooms). The refrigerant in
the lines can generate noise under certain operation-
al conditions.
»
Use the largest possible bending radii to avoid high
pressure losses.
6.1.1 Line lengths
»
Observe the maximum permissible line lengths for
the refrigerant lines.
»
Observe the maximum permissible height di󰀨erential

Refrigerant lines
6.1.2 Refrigerant pipes passing through open air
1 Appropriately sealed wall conduit (particularly where
there is a risk of ooding)
2 Appropriate sealing of the refrigerant lines as they
pass through the wall conduit
3 Refrigerant lines in open air (enclosed in thermal in-
sulation with UV protection)
4 Reinforced strip foundation
5 Drainage pipe (frostproof)
6 Foundation
Note
All solder joints on the refrigerant copper pipework
must be accessible all year round for mainte-
nance purposes (according to Regulation (EU) No
517/2014).
»
Run the refrigerant pipes between the indoor and out-
door units.
»
Allow some surplus length in the refrigerant pipes
between the connections at the indoor and outdoor
units.
»
Use suitable sound-insulating pipe xings to secure
the refrigerant pipes.
»
Do not install the pipe xings in the vicinity of bending
radii.
»
Insulate the refrigerant lines with suitable insulating
material where they pass through open air between
the indoor and outdoor units, to prevent the formation
of condensation and corrosion. When passing above
ground outside, the insulating material must also have
UV protection.
Note
Where the refrigerant pipes run horizontally through
open air, use suitable supports. Take steps to pre-
vent above-ground refrigerant pipes from being
walked or driven on.

Note
All solder joints on the refrigerant copper pipework
must be accessible all year round for mainte-
nance purposes (according to Regulation (EU) No
517/2014).
Note
If the pipe liner is laid empty, inserting the re-
frigerant lines afterwards will be di󰀩cult, if not
impossible, depending on the conguration of the
connection lines.
»
When laying refrigerant lines in the ground,
schedule the work so that the pipe liner can
be laid together with the pre-inserted refrig-
erant lines in the trench between the outdoor
and indoor units.

Refrigerant lines
1 Where the pipe liner has two 90° bends, it must be
laid together with the refrigerant lines.
2 If the pipe liner is laid empty, it will not be possible to
insert the refrigerant pipes afterwards.
»
For the underground pipe liner, use rigid underground
sewer pipes. We recommend using sound-insulated
underground sewer pipes.
»
Use a pipe liner of a suitable diameter for the sys-
tem-specic refrigerant pipes and the planned pipe
bends.
»
For 90° bends in the pipes, use either 3x30° or 6x15°
bending radii (depending on the diameter of the pipe
liner and the installation depth).
»
At the point where the refrigerant pipes are connect-
ed to the outdoor unit, create a suitable trench.
»
Dig a straight trench between the wall conduit and the
trench at the outdoor unit.
»
Lay the pipe liner, with the refrigerant pipes already
inserted, in the trench between the outdoor and in-
door units.
»
Lay the electrical control and power supply cables in
a suitable electrical conduit.
»
Allow some surplus length in the refrigerant pipes
between the connections at the indoor and outdoor
units.
»
Ensure that the open end of the pipe liner at the
outdoor unit is properly sealed. For sealing the re-
frigerant pipes in the pipe liner, use for example an
appropriate ring seal or a UV-resistant, permanently
exible sealing compound.
»
Any exposed refrigerant lines outside the pipe liner
must also be protected from a build-up of conden-
sation and corrosion using appropriate insulating
material. Outside, the insulating material must also
have UV protection.
Note
Insulation used beneath the soil must be of a
closed-cell material construction. Otherwise, the
thermal insulation value of the material will be im-
paired.
Material damage
PU foam is not suitable as a sealant for the pipe
liner.
6.2 Wall conduit
Whether the refrigerant pipes between the indoor and
outdoor units are to be routed above or below ground,
appropriate and system-specic wall conduits need to be
created through the outer wall of the building.
»
Ensure that the wall conduit is installed in an appro-
priate, plant-specic position layout.
»
Take the construction of the wall (tiles, concrete) into
account.
»
Take the prevailing groundwater situation into
account.
Material damage
Inadequate wall conduits can cause signicant
damage to property, due to water penetrating the
building or stonework (seepage, condensation,
ood water). With wall conduits created below
ground level, the breach must be appropriate to
local conditions at the site (e.g. non-accumulating
or accumulating seepage water, groundwater un-
der pressure).
»
Use a suitable pipe liner or wall sleeve for the
wall conduit.
»
Integrate the external end of the wall conduit
into the external waterproof seal of the build-
ing.
»
Ensure that the pipe liner is arranged with a
slight fall (at least 2%) to the outside.
»
Use appropriate ring seals to seal the space
between the wall sleeve and the refrigerant
pipes and electrical cables passing through,
on both the outer and inner edge of the wall.

Indoor unit
Material damage
PU foam is not suitable as a sealant for the pipe
liner.
7. Indoor unit
7.1 Installation location
Material damage
The indoor unit is intended to be installed inside the
building only. It must not be installed in rooms with
high levels of humidity (permanently above 70%).
The installation room for the indoor unit must meet the
following requirements:
►A dry and frost-free room
►Sound optimised environment
►A horizontal oor with adequate load bearing capacity
for the weight of the indoor unit
►Not directly below or next to rooms that are sensitive
to sound (e.g. bedrooms)
►Max. room temperature 30°C
►Installation room must not be subject to a risk of ex-
plosion arising from dust, gas or vapour
7. 2 Keep minimum clearances
Observing the specied minimum clearances for the indoor
unit ensures:
►Correct installation of the appliance
►That it operates fault-free
►Ability to carry out maintenance on the appliance
»
Observe the machine-specic minimum clearances.

8.1 Outdoor unit
8.1.1 Installation location
►The outdoor unit must not be surrounded by walls/
objects on all four sides.
►The outdoor unit must not be positioned immediately
adjacent to walls/objects on one, two or three sides.
Material damage
The outdoor unit must be positioned so that the
air ow is not blocked by accumulation of snow
in winter.
»
Take into account the expected depth of snow
at the installation site and position the outdoor
unit at a su󰀩cient height above the ground.
»
If necessary, construct a canopy above the
outdoor unit to protect it from any large accu-
mulation of snow.
»
Make sure that snow falling at the sides does
not damage the outdoor unit. If necessary
install a deection plate to divert the snow.
When doing so, observe the machine-specic
minimum clearances.
►When installing the outdoor unit, the expected wind
direction must be taken into account.
1 Wind direction
►The outdoor unit should be positioned with the air
outlet side facing a wall, ensuring that minimum clear-
ances are observed; this protects the air outlet side
from direct exposure to winds.
