1. Installation
1 - Mounting holes
2 - Manometer
3 - Ball valve with non-return
valve and dial thermometer
4 - Ball valve and flowmeter
5 - Full empty valve
6 - Full empty valve
7 - Air separator with manual
discharge (only FlowCon BL)
1.1 Mounting the pump group
• The front insulation jacket shall be pulled forward firmly so that the thermometer
sensors release from the sheaths.
Please fix the pump station with the rear insulation jacket in place!
• Determine the mounting place of the pump group, align it to the wall and mark the
hole center distance for holder (hole center distance 150 mm). Drill the holes, insert
dowels and fix the pump group to the wall with the enclosed fastening screws (plate
screws 6 x 60 mm).
• The manometer (2) must be inserted into the valve without using hemp or other
sealants. The manometer
• must be screwed as far as it will go and then slackened so that the display is
correctly aligned.
• Determine the mounting place for the expansion tank and install its connection set.
All fittings are factory pre-assembled. Please check all fittings are correctly tightened when
commissioning the pump group.

1.2 Integration of the Controller DeltaSol
®
BS
front insulation jacket rear insulation jacket
front view rear view
• Take off the front insulation jacket, starting from the top (hold the thermometers).
• Pull the part with controller recess downwards.
• Insert the Controller into the provided recess of the insulation and fix it by the
fastening screws (3 x 30) and large washers.
• Electrical connections (to plug, sensor and relay) must be made at the controller
according to the enclosed manual.
• The cables, especially that of the pump, must be of sufficient length so that the front
jacket can be removed without damaging the controller. Please ensure that the
cables do not touch hot pipes!
More detailed information for installation of the Controller can be found
in the DeltaSol BS Manual.
2. Filling and flushing the system
1. The ball valve (4) below the pump must be closed.
2. Open the full empty valve (5) and fill the system using a filling pump and allow the
medium to flow through the system until it discharges through the full empty valve (6).
Continue until clear medium appears. For further steps see Point 4 in Commissioning.
The complete solar system must not be flushed with water. As a total emptying of
the system is mostly not possible, there is a danger of frost damage.

3. Draining the system
1. Open both non-return valves in the ball valves (3) by using a wrench 14 for opening
halfway the ball valve (see non-return valves).
2. Fit a drain cock at the lowest point of the system.
3. Open all air vents at the collector in order to let air into the system and the collectors to
drain.
3.1 Emptying the system by using a filling pump
1. Open both the non-return valves in the ball valves (3) by using a wrench 14 by opening
halfway the ball valve (see non-return valves).
2. Connect the filling pump to the drain valve (6) below the circulation pump.
3. Open the drain cock to de-pressurise the system.
4. Start up the filling pump and immediately open the full empty valve (5) above the
circulation pump (manometer) so that air can be sucked in.
4. Commissioning / Working mode
1. Close the full empty valve and increase the system pressure to 5 bar by means of an
external filling pump via a full empty valve (5).
2. Close the full empty valve (5); open all ball valves of the system. Carry out a pressure
test of all system joints.
3. Let the system circulate for a moment and carry out the pressure test again (set the
controller to manual operation).
4. Open the vent valves at air separator (repeated venting!).
5. Adjust the system pressure to the working pressure value.
6. The solar system must be vented again after some operating hours. After venting the
system, please check the pressure of the system and if necessary, refill heat transfer
medium.
5. Non-return valves
The non-return valves are integrated in the ball valves and each have an opening pressure
of 200 mm water column each.
1. Both non-return valves must be opened for filling, draining and flushing the system.
They can be opened by opening halfway each ball valve using a wrench 14. Then the ball
of the ball valve presses on the non-return valve.
2. The ball valves must be completely opened for
operation of the system.

6. Expansion tank connection set
The expansion tank connection set consists of a stainless-steel corrugated pipe 0.5m long
with cap nuts on both ends, flat gaskets and connection screw joints for solar expansion
tank, and a mount strut for connecting an expansion tank.

TIGHTNESS TEST CERTIFICATE
The system shall be filled with water, air-bled properly, pressurized to the test
pressure of 5.5 bar and the whole system (all the connections, solar collectors,
valves…) examined. No visible leaks may be observed. The system remains under
pressure for at least 2 hours, after that it is re-examined.
The test result is considered successful when no leaks and/or no pressure depression
are observed.
