1.2 About solar pump station

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

from collector to storage. It contains important fittings and safety devices for the operation of

a solar thermal system:

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

circulation.

Airstopp for manual or automatic bleeding of the solar thermal system

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

SR882 operation manual

~ 5 ~

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

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 from safety valves. Therefore a discharge pipe must be

connected to the safety assembly, please observe the enclosed instructions regarding the

safety valve when doing this.

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 pump 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, mount the store and collector

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

Tighten all union nuts and screw connections. And mount 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 the 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

SR882 operation manual

~ 8 ~

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 1-20L/M, in order to

guarantee the flawless function of the measuring device the system must be flushed and

free from foreign substances.

3.3 Airstopp

After pump station is filled and commissioning, airstopp will automatically release air for

system, and it is possible to release air manually.

Factory default status of Airstopp is releasing air automatically.

In the case that airstopp is in automatic status,

anti-clockwise turn the knob180oto switch the

status to manual air releasing. (See picture 1)

In the case that airstopp is in manual status,

clockwise turn the knob180oto switch the

status to automatic air releasing. (See picture 2)

Airstopp is used for releasing the air from system. The air

released from solar liquid will assemble at the top part of airstopp

(see picture 3), and released from airstopp. In order to take the

air from pipe to airstopp, minimum flow speed of 0.3m/s should

be ensured.

After air releasing, please check the system pressure, if need,

please increase the system pressure to the desired operation

pressure by filling and flush station.

Warning: high temperature scald!

During air releasing, temperature of released air and liquid maybe over 100oC.

3.4 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. Pump, pipe

sensor and digital counter are already pre-connected with controller at factory. But

for connecting other wires, it needs to open the controller, 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 remove it by pulling it

downwards.

Connect the wires to controller, and doing reverse

steps to remount the front cover of controller and

insulation.

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

controller (2.3 Terminal layout and system description).
