5 Start-up and decommissioning
5.1 Start-up
All the following work must be carried out in the specified se-
quence.
1. Filling the storage cylinder:
Ɣ
Filling the heat exchanger for domestic water.
Ɣ
Fill the buffer storage volume via the filling and draining
hose (
KFE BA, 16 52 15
) on the regulation and pump
unit RPS4 until water comes out of the safety overflow.
Ɣ
Close the filling and drain valve (
KFE BA, 16 52 15
).
2. Switch on the Solaris R4 regulator.
Î
The initialisation phase begins.
3. When the initialisation phase is finished (temperature
display), fill and vent the solar system by simultaneously
pressing both arrow keys (starting manual mode).
Î
The solar operating pump P
S
now runs at full power and
the solar system is exposed to the maximum possible
operating pressure. The solar system fills, the air escapes
through the flow line into the air compartment of the stor-
age tank.
4. Check the entire system for leaky joints (in the building and
on the roof). Seal any leaks that occur in a professional
manner.
5. Switch off the Solaris R4 regulator.
6. Check the filling level in the hot water storage tank.
7. Adjusting the filling time:
Ɣ
Switch the Solaris R4 regulator on again (initialisation
phase starts).
Ɣ
When the initialising phase is finished (temperature
display), you can start the manual operating mode by
simultaneously pressing both arrow keys.
Ɣ
Measure the time it takes to fill the solar system
completely. The system is fully filled when you can no
longer hear any air noises and a steady value for the flow
rate is displayed (activate the measuring point [Flow rate]
using the arrow keys).
Ɣ
Set the measured time plus 20 seconds in the
parameter [time P2] (see section 6.3.6).
8. Switch the Solaris R4 regulator to the automatic mode by
pressing the two arrow keys simultaneously or by switching
off and on again.
Î
The solar system is now ready for operation.
9. Only when connecting a RPS4 regulating and pump unit to
several solar storage tanks:
– The entire flow rate, measured with the FlowSensor in the
solar flow line must be distributed evenly to all the con-
nected solar storage tanks. We recommend using a
FlowGuard (FLG) at each storage tank for regulation pur-
poses.
10. Instruct the user, fill out the acceptance report, and send it to
the address indicated on the rear cover of this manual.
WARNING!
The solar system cannot be started until all
hydraulic and electrical connections have been
completed.
Incorrect commissioning will impair the system's
function, and can lead to damage to the entire
installation. Installation and start-up must
therefore must conducted by ROTEX-au-
thorised and trained heating experts.
The protective conductor resistance and correct
wiring must be checked before start-up.
CAUTION!
Commissioning in frosty conditions can result in
damage to the entire heating system.
Ɣ
Commissioning with outside temperatures
below 0°C should only be undertaken if a
water temperature of at least 5°C in the solar
circuit can be guaranteed (e.g. by previous
heating of the DHW cylinder).
ROTEX recommends that you avoid operating
the system in extremely frosty conditions.
UK only!
CAUTION!
If filling or topping up the storage tank is done by
means of the boiler filling and drain valve, a
temporary filling loop must be used with the
appropriate backflow prevention device in
accordance with clause G24.2, Guidance to the
Water Supply (Water Fittings) Regulations
1999.
The domestic water quality must comply with the
EU Guideline 98/83 EC and the regionaly-applica-
ble regulations.
Within a few minutes after switching off and emptying of
the solar system, the fill level indicator in the hot water
storage tank once again reach almost to the fill level.
– The reason for a slightly lower fill level is the remaining of a
small volume of water in the lower collection pipes in the pan-
els. If the solar panels are correctly aligned, this volume of
water is not dangerous for the panel, even under the effects
of frost, since there is adequate space for expansion.
– If the fill level remains considerably below the fill level, this
can be an indication of undiscovered leaks or faulty line rout-
ing (water pockets). In this case the installation must be
checked very closely once more.
The correct flow rate in the solar circuit is set automati-
cally by regulating the speed of the solar operation
pump P
S
.
