1.2 About this manual

This solar pump station is a preinstalled and leak-tested group of fitting for transferring heat

from the collector to the store. It contains important fittings and safety devices for the

operation of the solar thermal system:

Ball valves in flow and return in combination with check valves to prevent gravity

circulation.

Flow rate check for displaying the flow rate

Manometer for displaying the system pressure

Safety valve to prevent inadmissible overpressure

Flushing and filling unit (optional) for flushing, filling and emptying the solar thermal

system.

1.3 Safety instructions

The installation and commissioning of the solar station as well as the connection of

electrical components requires technical knowledge commensurate with a recognized

vocational qualification as a fitter for plumbing, heating and air conditioning technology, or

a profession requiring a comparable level of knowledge. The following must be observed

Solar working station operation manual SR881

- 5 -

during installation and commissioning:

The relevant regional and national regulations.

The technical and safety instructions of these instructions.

Warning: risk of scalding

There is danger of steam emission with safety valves. Therefore a discharge pipe must be

connected to the safety assembly.

Attention: damage of solar pump station

The group of fittings must be installed with sufficient spacing to the collectors because

temperatures in the vicinity of the collectors can be very high. An intermediate vessel

may be necessary for installation in the attic.

It is imperative that you make sure the PTFE sealing elements of the solar pump station

do not come into contact with substances containing mineral oil. Mineral oil products

cause lasting damage to the material, whereby its sealant properties are lost.

If necessary, ask the manufacturer whether the solar fluid, fats or installation aids

contain mineral oils.

We don’t assume liability nor provide warranty for damage to solar station resulting

from sealants damaged in this way.

2. Mounting station

Determine the mounting site of the station.

Take the station out of packing; Remove the

front half of the insulation.

Hold the enclosed wall mounting bracket

against the wall and mark the fastening holes,

drill holes and insert dowels.

Fasten the wall mounting bracket to the wall

with the screws.

Push the station against the wall mounting

bracket, the station catches and is then

attached to the wall.

Connect the station to the solar thermal system.

Check the inlet pressure of the expansion vessel and if necessary, adjust it to the local

conditions, Pinlet(bar) = 1bar+∆ Th(m)*1/10 （∆Th=height difference between collector

and station）.

Connect the electrical components of the solar station, Attach the store and collector

sensor and connect there to the controller, plug the controller into the socket.

Tighten all union nuts and screw connections.

Attach the front half of the insulation to the station.

3. Commissioning of station

Attention: Risk of scalding!

In order to prevent the boiling of solar fluid in the collectors, the system should not be

flushed or filled during periods of strong sunshine.

Attention: Risk of frost!

Solar thermal system cannot be completely emptied after flushing. There is a danger of frost

damage if water is used for flushing. Only use solar fluid to flush and fill the solar thermal

system. Use water –propylene glycol mixture as solar fluid (Maximum 50% propylene

glycol).

3.1 Flushing and filling the solar system

Flushing and filling unit is optional component, it can be installed horizontally at the lowest

point of the solar circuit (see figure). A filter must be installed between the store and solar

pump in order to prevent the flushed-out scale from store re-entering the solar circuit.

Flushing and filling steps:

Disconnect the expansion vessel from the solar thermal system.

Connect the pressure hose of a flushing and filling station to the fill ball valve (1) of

flushing and filling unit.

Connect the flushing hose of a

flushing and filling station to the

drain ball valve (3) of flushing

and filling unit.

Close the ball valve (2) in the

centre of the flushing and filling

unit.

Open the filling ball valve (1) and

drain ball valve (3).

Flush the solar thermal system

using the flushing and filling station for at least 15minutes to remove all air from the

system.

During the flushing, bleed the solar thermal system several times at the airstopp until

the discharged solar fluid is free of air bubbles.

Close the drain ball valve(3) of flushing and filling unit, and continues run the pump and

increase the system pressure to approx.5 bar, system pressure can be read from the

manometer.

Close the filling ball valve (1) of the flushing and filling unit, and then close the filling

pump.

Check the manometer to see whether the system pressure reduces and eliminate leaks

where necessary.

Reconnect the expansion vessel to the solar thermal system.

3.2 Flow check

The flow counter is used for measurement and display of flow rate, in order to guarantee the

flawless function of the measuring device the system must be flushed and free from foreign

substances.

Digital flow meter（1-20L/min）Mechanical flow meter（2-8L/min）

3.3 Electrical connection

Warning: disconnect the controller from power supply before opening the housing!

The controller is already integrated in the station

and ready to plug in, display and digital counter

are already preinstalled at factory. For

maintenance or service work, it needs to take

out the controller from station, doing follows

below steps:

Switch off the system, disconnect plug from

the mains.

Remove the front half of the insulation.

Unscrew the cross-recessed screw 1 of the front cover of controller and left moving out

the cover 2.

Disconnect the wires from controller, take out the controller.

Doing reverse steps to remount the controller.

For further information on electrical connection of the controller, please see manual of

controller (terminal layout).
