1 General information
1.1 Information on documentation
The following information is a guideline for the
complete documentation.
Please read your heat pump's operating manual
carefully from beginning to end. This will help you
to operate your heat pump better. This manual is
to be kept readily accessible near the heat pump.
The precautionary information provided below is
used in this document.
WARNING
Failure to observe this information
poses a risk of injury or death and may
lead to material damage. This
information must be observed without
fail.
CAUTION
Failure to observe this information
may lead to an appliance fault or
material damage. This information
should be observed.
NOTE
CAUTION
Information for work on electrical
systems. This information must be
observed without fail.
Caution - risk to life
1.2 Safety regulations
Read this manual through carefully before
commissioning the heat pump or making settings!
The appliance must not be converted or
modified in any way. Work on the
appliance (repairs, modifications)
may only be carried out by authorised
bodies.
Turn off all mains fuses of the system
before carrying out any work on plug-
in strips or electrical connections
(wires).
Commissioning and servicing of the
appliances may only be carried out by
personnel authorised by OCHSNER.
Installation of the appliances and
their wiring may only be carried out
by a specialist in accordance with local
regulations.
The controller can be used to enable
functions to protect the heat pump.
However, since the controller is not
certified as a safety device, safety
measures in case of failure of or
damage to the heat pump (e.g.
additional external switching of the
safety devices in use) must comply
with local regulations.
CAUTION
Note that there is a risk of injury when
touching the outdoor unit. This applies
in particular to AIR BASIC 618 without
a cover grille.
WARNING
Do not use the appliance as a step or
platform. Do not climb on the
appliance or place any loads on it.
In the event of upgrades/updates to the controller
software, all function parameters of the heat
pump should be checked.
1.3 CE designation
The product you have purchased conforms to the
technical regulations valid at the time and is
compliant with CE standards.

3.3 Outdoor unit installation
The outdoor unit can be wall mounted or
installed on the floor.
WARNING: Slipping hazard
If drainage for condensation is
inadequate, ice can build up in winter
in the area around the outdoor unit.
- Ensure drainage for
condensation is sufficient even
at low temperatures.
- Ensure that no ice is formed,
especially around walking
surfaces and entrances around
the outdoor unit.
NOTE
Avoid installation with the broad side of
the outdoor unit facing the prevailing
wind direction. Also avoid installing the
outdoor unit in an open and exposed
location, e.g. on a flat roof. Wind can
cause problems with de-icing on the
outdoor unit in defrosting mode due to
increased heat dissipation. We
recommend installing the outdoor unit
with the rear facing a wall.

When installing the AIR BASIC 211 outdoor unit,
acoustic reflections from the wall can be avoided
by maintaining clearance c between the
connection side and the wall. See illustration
below.

982017-AIR-BASIC-Multitower-T201-EN01.docx Page 9 of 60
WARNING
Risk of injury due to the evaporator
fins on the rear of AIR BASIC 618
outdoor units. Always install the outdoor unit with
the rear parallel to a wall with clearance b (see
Figure 4).
Figure 7: Inadmissible installation AIR BASIC 618

3.4 Foundation for floorstanding
installation
NOTE
Observe the minimum clearances in
section 3.3.1.
CAUTION
A load bearing base is required for the
outdoor unit.
We recommend erecting foundation strips on site.
These must be horizontal and extend at right
angles to the front view (= side of the appliance
with access to refrigerant pipe connections and
electrical connection) of the outdoor unit to be
installed.
The thicknesses of cover are average values and
should be matched to local conditions. This must
be done in accordance with the applicable
engineering standards!
Installation on a foundation according to
the description is mandatory as ice may
form underneath the outdoor unit after
defrosting if meltwater cannot drain into the
gravel bed.
The outdoor unit must be firmly bolted
to the foundation to ensure that it
cannot tip over due to wind (see Fehler!
Verweisquelle konnte nicht gefunden werden., 0
and 3.4.1).
Ensure that the mounting feet of the
outdoor unit are at least 300 mm clear
of the surrounding terrain. Take the
expected snow depth at the installation site into
consideration.

982017-AIR-BASIC-Multitower-T201-EN01.docx Page 10 of 60

The floor brackets must be anchored on site using
long screws in the fully cured foundation strips
(tipping protection).
Recommendation:
Drill 2 holes in each of the floor brackets at the
appropriate locations (hole diameter 14 mm) and
anchor in the foundation using 4 V2A hexagon
screws (12 x 180), V2A washers A 13 and S 12
plugs.

3.5 Wall bracket for wall mounting
NOTE
Observe the minimum clearances in
section 3.3.1.
Ensure that the mounting feet of the
outdoor unit are at least 300 mm clear
of the surrounding terrain. Take the
expected snow depth at the installation site into
consideration.
The outdoor units can be wall mounted using a
wall bracket.
The wall bracket consists of:
- 2 x wall bracket 600
- 4 x M10 threaded plate
- 4 x M10 washers
- 4 x M10 nuts
- 4 x rubber/metal buffers (A 40/30 M10) for
sound insulation

3.5.2 Installing the wall bracket
CAUTION
The wall bracket must only be used for
installing the outdoor unit.
CAUTION
Before securing the wall bracket, ensure
that the wall has been tested according
to the specified loads for the respective
outdoor unit. The applicable engineering
standards must be observed.
NOTE
Ensure that the heat pump outdoor unit
is accessible for service and
maintenance work throughout the year.

982017-AIR-BASIC-Multitower-T201-EN01.docx Page 14 of 60
Installation procedure:
- Observe the distances between mounting
feet specific to the outdoor unit (see 3.2
Dimensions). The distances for the holes
required in the wall are derived from
these.
- Drill the holes in the wall.
- Install the wall brackets.
- Install the 4 rubber/metal buffers for
sound insulation to the wall brackets.
Observe the distances between holes for
the outdoor unit mounting feet.
- Place the outdoor unit mounting feet on
the rubber/metal buffers.
- Screw the outdoor unit to the
rubber/metal buffers.

4.1.1.1 DHW tank
The steel tank is fitted internally with a special
direct enamel and a sacrificial anode. The anode
with wear indicator protects the inside of the tank
against corrosion.
The heating water heated by the heat pump is
pumped through an internal indirect coil in the
DHW tank. The internal indirect coil transfers the
absorbed heat to the DHW. The integral heat
pump manager controls DHW heating to the
required temperature.
4.1.1.2 Buffer tank
The steel tank serves to hydraulically separate the
flow rates of the heat pump and the heating
circuit. The heating water heated by the heat
pump is transported to the buffer tank by the tank
charging pump. When there is a demand, the
heating water is supplied to the heating circuit by
the integral heating circuit circulation pump.
4.1.1.3 Heat pump manager (OTE)

982017-AIR-BASIC-Multitower-T201-EN01.docx Page 16 of 60
The system is controlled via the integral OTE3 heat
pump manager. For adjustment options, see the
controller operating manual.
4.1.1.4 Multifunctional assembly (MFA)
The multifunctional assembly switches between
heating circuit and DHW heating. It also includes
the safety valve, an air vent valve the flow sensor
and the electric emergency heater.
4.1.1.5 Accessories pack
The following components are packed inside the
MULTI TOWER, next to the two pumps:
-Outside temperature sensor
-Adjustable feet
-Drain hose
-Operating manual
-1 expansion vessel (incl. fastening
material)
-1 installation kit (pressure reducing valve,
check valves, expansion, relief valve,
tundish)
Gaskets for the hydraulic connection (heating
circuit flow, heating circuit return, cold water,
DHW) are attached directly at the connections.

4.1.3 Installation
4.1.3.1 Installation location
CAUTION
Do not install the appliance in damp
rooms!
Install the appliance in a frost free and dry room
near the draw-off point. In order to reduce line
losses, keep the distance between appliance and
heat pump small.
Ensure that the floor has adequate load bearing
capacity and is sufficiently level (for weight, see
section "Specification / Data table"). The room
must not be endangered by explosive dust, gases
or vapours.
If installing the appliance in a boiler room with
other heating appliances, ensure that their
operation is not affected.
