ÎDetermine the mounting site of the station.
ÎMark the drill holes by means of the template enclosed, then drill and insert
wall plugs (see gure to the right).
ÎTake the station out of the packaging.
ÎRemove the front half of the insulation. Leave the pump station attached to the
back half of the insulation!
ÎFasten the pump station to the wall with the enclosed screws. For this pur-
pose, use a crosshead screw driver.
ÎConnect the pipework between pump station and store and collector re-
spectively.
Note
All connections are already tightened such that they usually do not have
to be tightened again. However, during commissioning of the system all
connections have to be checked for leaks (pressure test).
3 Flushingandllingthesolarsystem
WARNING! Scald danger!
Pressure surge damage!
If the medium enters strongly heated, empty collectors, pressure
surges caused by evaporation can occur.
ÎIn order to prevent the solar uid from vaporising
inside the collectors, do not ll or ush the system
during times of strong irradiation!

Beforeushingthesystem
ÎDisconnect the expansion vessel from the solar thermal system.
2.
ÎConnect the pressure hose of the lling and ushing station to the ll valve
(5) of the pump station.

en
5
ÎConnect the ushing hose of the lling and ushing station to the drain valve
(3) of the pump station.
ÎClose the ball valve of the pump station (4).
ÎOpen the ll valve (5) and the drain valve (3).
ÎSwitch on the lling pump of the lling and ushing station.
ÎFlush the solar thermal system for at least 15 minutes by means of the lling
and ushing station until the discharged solar uid is free of gas bubbles and
dirt particles.
ÎDuring ushing, bleed the solar thermal system several times until the dis-
charged solar uid (e. g. Tyfocor®, see chap. 10) is free of air bubbles.
ÎOpen the ball valve (4) of the pump station.
Afterushingthesystem
ÎConnect the expansion vessel to the solar thermal system
ÎClose the drain valve (3) of the pump station while the lling pump is running.
BAR
ÎIncrease system pressure (approx. 3.5-4 bar). The system pressure can be read
from the pressure gauge.
ÎClose the ll valve (5).
ÎSwitch off the lling pump.
ÎCheck the pressure gauge to see whether the system pressure reduces and
eliminate leaks where necessary.
ÎSlowly discharge the heat transfer uid by means of the drain valve (3) until
the operating pressure is set.
ÎRemove the hoses of the lling and ushing station and screw the caps onto
the ll and drain valves.Manually start the solar thermal pump at maximum
speed (see controller manual) and let the uid circulate for at least 15 minutes.
ÎBleed the solar thermal system several times.
ÎCheck the system pressure at the pressure gauge.
11.
%
ÎCheck the antifreeze ratio (not required if a ready -mix is used).
4 Ball valve positions
Ball valve closed, no uid ow
Ball valve open, uid ow in both directions possible
Ball valve in operating position, uid ow in ow direction only
5 Draining the system
ÎOpen the ball valve (4).
ÎOpen the air vent at the highest point of the system (above the collectors).
ÎOpen the drain valve.
6 Non-return valve
ÎThe non-return valve of the pump station is integrated into the ball valve
above the circulating pump. It has an opening pressure of 20 mbar.
ÎIn order to completely drain the system, the non-return valve has to be
opened. For this purpose, turn the handle of the ball valve by 45°.
ÎFor normal system operation, open the ball valve completely.
ÎIn order to avoid in-pipe-circulation, the ow line has to be equipped with a
thermosiphon or an additional non-return valve.

en
6
7 Flowmeter
The owmeter measures and indicates the ow rate with a range of 1-13 l/min.
For the device to function faultlessly, the system must be ushed and free of grit.
Read the ow rate from the upper edge of the oat.
8 Maintenance
In the case of maintenance (such as a replacement of the pump) proceed as follows:
ÎClose the ball valve (4).
ÎTurn the slot of the owmeter spindle by 90° anti-clockwise (see gure below).
The heat transfer uid can now be drained from the pump.
ÎOpen the drain valve (3).
If necessary, open the union nut at the pressure side.
ÎNow dismount the pump.
9 Safety devices
The pump station is equipped with a diaphragm safety valve which corresponds to
the relevant directives and regulations. For installation and operation, please pay
attention to the following advice:
• The safety valve has to be easily accessible. The efciency of the valve must not
be inuenced or disabled by barriers!
• The strainer or other restriction devices must not be mounted between collec-
tor (-eld) and safety valve!
• The diameter of the discharge pipe must correspond to the diameter of the
valve outlet; the maximum length must not exceed 2 m; more than 2 bends are
inadmissible. When these values are exceeded, you have to install a discharge
pipe with larger dimensions. Do not use more than 3 bends and pipes longer
than 4 m!
• If the discharge pipe leads into a drain pipe with a funnel, the diameter of the
drain pipe has to be at least twice as large as the valve inlet. The opening of
the discharge pipe must be inclined downwards. It must be routed such that
the opening can be seen but does not present any risk to a person standing or
passing by.
• We recommend placing a container below the discharge pipe. If the safety valve
opens, the uid will be collected and can be relled into the system when the
pressure is too low.
