Store unit protected against:
Moisture/damp
Frost
Dust and dirt
10.2 Transport to installation location
NOTE
It must be installed in a frost-free room with
short pipe lengths to the load. Please also
ensure that it is installed on a dry, firm sur-
face able to safely support its weight.
“Technical data, weight” overview
To avoid damage during transport, you should
transport the storage tank (secured on the wooden
pallet) to its final installation location using a lifting
truck.
If it is not possible to transport the unit to the final
installation location using a lifting truck, you can also
transport the unit using a hand truck.
WARNING
Several people are required to transport
the unit. Do not underestimate the weight
of the tank.
“Technical data, weight” overview.

Subject to change without notice | 83017400eUK | ait-deutschland GmbH
WARNING
The unit can tip over when being removed
from the wooden pallet and during
transport with a hand truck or lift truck.
This can result in personal injuries and
damage.
Take suitable precautions, which prevent
the tipping hazard.
Proceed as follows if transport with a lifting truck is not
possible:
Remove packaging and insulating material. Remove
storage tank from the wooden pallet and bring it to the
installation location.
Dispose of the transport and packaging materials
properly and under ecological aspects.
Fastening on the wooden pallet
NOTE
The multi-functional domestic hot water stor-
age tank is delivered with full insulation. If
necessary, the insulation (Sky jacket and the
4 insulation shells) can be removed to trans-
port the tank into the basement.
IMPORTANT
All parts of the insulation must be carefully removed
and put aside so that they are not damaged.
1. Remove the protective transport sheeting.
2. Remove the grommets from the connections.
3. Lift off the tank cover.
4. Undo the Sky jacket zip and remove the jacket.
5. Remove both insulation shells and put them in a
safe place.

8Subject to change without notice | 83017400eUK | ait-deutschland GmbH
NOTE
Please note that all components must be re-
assembled in the reverse order.
WARNING
Make sure you secure the tank against
slipping during transport. Always secure
the tank on the hand truck with a ratchet
strap.
10.3 Installation
NOTE
Ensure that the foam insulation is still in the
bottom of the storage tank.
WARNING
The storage tank must always be tilted by
at least 2 people to prevent the risk of it
tipping over. Do not tilt the storage tank by
more than 20° during this step. Hands and
fingers can be crushed when the tank is
righted.
Do not grip the bottom of the tank.
1. Before you re-attach the insulation half-shells,
check whether a) the grommets are placed over
the pipe sockets and b) the soft foam sleeve is po-
sitioned over the top connection.
a) Grommets
b) Sleeve
2. Re-attach the insulation half-shells to the storage
tank.
3. Use adhesive tape to fix the insulation half-shells
at the top, bottom and in the middle part of the
tank.
4. Place the Sky jacket around the storage tank so
that the punched out holes fit over the sockets.
Then close the zip.
IMPORTANT
The zip must be closed by two people to relieve the
strain.

5. Replace the tank cover and push the grommets
over the corresponding pipe connections.
11 Installing the hydraulic
connections
11.1 Circulation connection kit
NOTE
The connection between the top and bot-
tom heat exchanger must always be installed,
even if there is no circulation pipe.
1. Seal the two threads (1 and 2).
2. Screw the tee onto thread 1 and move into the cor-
rect position (connection part facing downwards).
3. Seal the thread of the flexible corrugated pipe and
screw into the tee.
4. Screw the 90° elbow onto thread 2 and move in-
to the correct position (elbow must face upwards).
5. Stretch the flexible corrugated pipe and insert the
seal between the elbow and the flexible corrugated
pipe.

10 Subject to change without notice | 83017400eUK | ait-deutschland GmbH
6. Use the union nut to screw together the flexible
corrugated pipe and the elbow.
IMPORTANT
Tighten the union nut carefully to prevent damage to
the seal.
11.2 Insulate the circulation connection
NOTE
The circulation connection is installed outside
the shell insulation over the Sky jacket and is
then insulated.
1. Push the 110 mm long insulation hose (with pipe cut-
out) over the thread of the circulation connection.
2. Insulate the remaining piping of the circulation
connection with 220 mm long insulation hose (1).
Then fix the insulation hoses in 4 places using the
cable ties (2).
11.3 Hydraulic connections
Note and follow all relevant regulations, standards,
guidelines and directives when integrating the multi-
functional storage tank in the drinking water and heating
network.
Note and follow the relevant DVGW regulations and
recommendations and the regulations of the water
supply company when connecting to the drinking
water.
Integrate the storage tank in the heating system
and domestic hot water circuit as shown in the hy-
draulic diagram.
Hydraulic connection
IMPORTANT
Damage to the copper pipes due to unacceptable
loading.
Secure all connections against twisting.
Do not exceed the operating pressures specified on
the name plate and in the technical data.
Install a pressure reducer, if necessary.
Ensure that the drinking water is of drinking water
quality.
IMPORTANT
The drinking water must meet the following condi-
tions:
Chloride content < 200 mg/l
Sulphate content < 250 mg/l
pH value 6.5 – 8.5
Electrical conductivity 130 – 1500 µS/cm
We recommend installing a suitable expansion vessel
(not included in delivery) in the hot water circuit. This
equalises pressure fluctuations or water shocks in the
cold water network and prevents unnecessary loss of
water.
Use a safely valve according to the respective relevant
standards, guidelines and directives and according
to the maximum allowable operating pressures of the
storage tank and components.
The safety drain of the safety valve must lead into
the drain via a funnel siphon in accordance with the
applicable standards and regulations.

water sensor and return temperature sensor).
1. Position the sensor on the outside of the sensor
spring.

2 Sensor
3 Sensor pocket (is already installed in the tank)
2. Push the sensor and sensor spring together into
the respective sensor pocket.
3. Push in the sensor up to the end of the sensor
pocket.
For position of the sensor pocket, see dimen-
sioned drawing
NOTE
Always install the sensor springs, to ensure
optimum temperature transfer. Take care not
to damage the insulation of the sensor cable.
4. Connect the sensors to the heating and heat pump
controller according to the specifications in the ter-
minal diagram.
Terminal diagram of the respective unit type.
NOTE
Refer to the instruction manual for the heat-
ing and heat pump regulator for the regula-
tor settings required for parallel tank. Refer to
the terminal diagram of the respective heat
pump type for details of the circulating pump
connections and, if installed, the switching
valve for domestic hot water.

Important notice !
These hydraulic diagrams are schematic representations and are for assistance only. They do not relieve of the obligation to carry out appropriate planning! They do not include all necessary shut-off valves, ventilator fittings or safety devices. These must be incorporated in accordance with the standards and regulations applicable to the respe
ctive installation. All country-specific standards, laws and regulations must be observed! The
tubes have to be dimensioned according to the nominal volume flow of the heat pump resp. the free pressing of the integrated ci
rculating pump. For detailed information and advice please contact our local sales partner!
