11 Transport, Installation,

Assembly

The following applies to all work to be done:

NOTE

Always comply with the applicable local ac-

cident prevention regulations, statutory regu-

lations, ordinances, guidelines and directives.

WARNING

The storage tank may only be installed and

assembled by qualified technicians!

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

11.1 Transport to installation location

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.

CAUTION

Wear safety gloves.

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 pre-

vent 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.

Subject to change without notice | 83017400dUK | ait-deutschland GmbH

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.

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!

11.2 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!

Wear protective gloves!

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.

8Subject to change without notice | 83017400dUK | ait-deutschland GmbH

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 re-

lieve the strain!

5. Replace the tank cover and push the grommets

over the corresponding pipe connections.

11.3 Circulation kit installation

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

correct position (connection part facing down-

wards).

3. Seal the thread of the flexible corrugated pipe and

screw into the tee.

Subject to change without notice | 83017400dUK | ait-deutschland GmbH

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.

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!

11.4 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).

11.5 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 multi-functional storage tank in the

heating system and domestic hot water circuit as

shown in the hydraulic diagram.

Hydraulic connection

10 Subject to change without notice | 83017400dUK | ait-deutschland GmbH

Do not exceed the operating pressures specified on

the rating plate and in the technical data. Install a

pressure reducer, if necessary.

IMPORTANT

The electrical conductivity of the domestic

hot water must be > 100 µS/cm and lie within

the required drinking water quality. The sul-

phate and chlorine content must not exceed

300 mg/l in total!

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!

11.6 Sensor installation

Always use the sensor springs included in the scope

of delivery when installing the sensors (domestic hot

water sensor and return temperature sensor).

1. Position the sensor on the outside of the sensor

spring.

1 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!

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 changeover

valve!

Sensor connection as shown in the “terminal dia-

gram of the respective heat pump type”.
