1General Information

Carefully read these instructions before installation and commissioning.

Save these instructions in the vicinity of the installation for future reference.

1.1 About these instructions

These instructions describe the installation, commissioning, function and operation of the

1.2 About this product

The station is a premounted group of fittings checked for tightness and used to transfer

the heat from the primary or solar circuit to the secondary or storage tank circuit.

The station contains important valves, fittings and safety devices for the operation

of the installation:

Ball valves with integrated thermometers in the solar circuit (flow and return)

Ball valves in the storage tank circuit (flow and return)

Check valves to avoid undesired gravity circulation in the flow and

return of the primary circuit and in the flow of the secondary circuit

Pressure relief valves to prevent inadmissible overpressures

Pressure gauge to display the system pressure in the solar circuit

Vent valves for an easy venting of the solar circuit

Fill and drain valves with caps to flush, fill and drain the solar circuit

Two flow meters on the primary and secondary side for the balancing of the flow rates

The expansion tank required for operation must be adapted to the size and the requirements

of the installation and must be ordered separately.

The separately available cap valve and the tank connector allow an easy mounting

and separation of the expansion tank from the solar installation.

The wrapping materials are made of recyclable materials and can be disposed of

with recyclable materials.

1.3 Designated use

The station may only be used as a separation system between the solar and the heating circuit

in solar thermal systems taking into consideration the technical limit values indicated in these

instructions. Due to its design, the station must only be mounted and operated as described

in these instructions!

Only use original accessories with the separation system.

Improper usage excludes any liability claims.

Under the influence of solar radiation, the collectors can get very hot.

The solar fluid in the solar circuit can heat up to more than 100 °C.

Only flush and fill the solar circuit if the collector temperatures are

below 70 °C.

2Safety instructions

The installation and commissioning as well as the connection of electrical components require

technical knowledge commensurate with a recognised vocational qualification as a fitter for

plumbing, heating and air conditioning technology, or a profession requiring a comparable

level of knowledge [specialist].

The following must be observed during installation and commissioning:

relevant local and national regulations

accident prevention regulations of the professional association

instructions and safety instructions of this manual

WARNING

Danger of scalding due to vapour escape!

With pressure relief valves, there is a risk of scalding due to vapour escape.

During installation, check if the local conditions require the connection of a

discharge line to the safety group.

For this purpose, please observe the instructions regarding the

pressure relief valve.

The pressures calculated by the installation planner for the expansion

tank and the operating pressure of the installation must be set.

CAUTION

Risk of burns!

The valves, fittings and the pump may heat up to more than 100 °C

during operation.

The insulating shell must remain closed during operation.

CAUTION

Personal injury and damage to property due to overpressure!

By closing the two ball valves in the primary circuit, the safety group is separated

from the heat exchanger. A rise in temperature in the storage tank will cause

high pressures which can result in personal injury or damage to property!

Only close the ball valves for service and maintenance.

NOTICE

Material damage due to mineral oils!

Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant

properties get lost. We do not assume liability nor provide warranty for damage to property

resulting from sealants damaged in this way.

It is imperative to avoid that EPDM gets in contact with substances containing

mineral oils.

Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as

Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.

3Assembly and installation [specialist]

The location of installation must be dry, load-carrying, frost-proof and protected against

ultraviolet radiation. Furthermore, the access to the control and safety equipment must

be guaranteed at all time during operation!

The discharge lines of the pressure relief valves must be conducted into heat-resistant

collecting containers of corresponding size. An uncontrolled discharging into the environment

is thus avoided and the refilling of the circuits is facilitated.

NOTICE

Material damage due to high temperatures!

As the solar fluid can be very hot near the collector, the group of fittings must be installed

at a sufficient distance from the collector field.

It may be necessary to install an intermediate tank to protect the expansion tank.

1. Remove the station from the packaging.

2. Copy the measure for the mounting holes to the

mounting surface. You will find a corresponding

drilling template on the paper board under the station.

3. Drill the holes and insert appropriate wall plugs into

the holes.

4. Screw in the screws and let them stick about 3 cm

out of the wall.

5. Remove the insulating front shell. Hang the

station onto the screws and tighten the screws.

6. Connect the station to the installation

by using the piping:

① Solar flow from the collector

② Solar return to the collector

③ Flow to the buffer tank

④ Return from the buffer tank

All thread connections have ¾" internal threads.

7. Mount the safety group, consisting of the pressure

relief valve [c], the fill valve [d] and the pressure

gauge [e] to the connection of the return ball valve [b].

8. Connect the pipe for the expansion tank below

the pressure gauge [e] and fix the bracket for

the expansion tank.

For service work on the expansion tank, we

recommend the installation of a cap valve

or a tank connector on the expansion tank.

NOTICE

Note regarding the expansion tank

During the flushing and filling of the station, the expansion tank must not be connected in order

to avoid that dirt particles are washed in.

9. Adapt the initial pressure of the expansion tank to

the installation and connect the expansion tank.

Please observe the separate instructions regarding

the expansion tank!

10. Check all thread connections and tighten them

if necessary.

3.1 Controller connection

WARNING

Risk to life and limb due to electric shock!

Prior to commencing electrical work on the controller, pull the mains plug!

Only after completing all installation work as well as the flushing and filling,

the mains plug of the controller can be plugged into a socket.

An unintentional start of the motors is thus avoided.

NOTICE

Damage at the pump!

An improper electrical connection of the pump to the mains and to the controller leads

to irreparable damages of the pump!

Observe the electrical connections between the pump and the corresponding

voltage source.

1. Connect the pump to the controller

(not included in the scope of delivery):

1 = Controller connection (PWM signal)

2 = Connection mains plug

Please observe the separate

instructions regarding the controller!

2. Tighten all union nuts and thread connections.

The assembly of the station is now completed

and the station can be put into operation.
