Flushing And Filling The Solar Thermal System - Resol SBS 1000 Guía De Conexión Y Operación

SBS 1000
3.2 Flushing and filling the solar thermal
system
• Disconnect the expansion vessel from the solar
thermal system.
• Connect the pressure hose of the SBS 1000 to the fill
valve (5) of the flushing and filling unit.
• Connect the flushing hose of the SBS 1000 to the drain
valve (3) of the flushing and filling unit.
• Close the ball valve (4) in the centre of the flushing and
filling unit
• Turn the ball valves in flow (1) and in return (2) with an
open-ended spanner to a 45° position. The non-return
valves in the ball valves are now open.
•
Open the fill and drain valves (3 and 5).
• Open the ball valves of the SBS 1000.
• Flush the solar thermal system using the flushing and
filling station for at least 15
transfer fluid is free of dirt particles and
• During flushing, bleed the solar thermal system several
times at the AirStopp (6) until the discharged heat
transfer fluid is free of air bubbles.
• Close the drain valve (3) of the flushing and filling unit
with the filling pump running and increase the system
pressure to approx. 5 bar. The system pressure can be
read from the manometer
• Close the fill valve (5) and switch off the pump of the
flushing and filling station.
• Check the manometer to see whether the system
pressure reduces and eliminate leaks where necessary.
• Reconnect the expansion vessel to the other compo-
nents of the solar thermal system.

Example: pump station RESOL FlowCon C
• Open the fill valve (5) and switch on the filling pump.
• Set the operating pressure of the solar thermal system
(approx. 0.5 bar higher than the inlet pressure of the
expansion vessel or the indications made by the manu-
facturer).
• Switch off the filling pump, close the fill valve (5) and
open the ball valve (4).
• Slowly discharge the heat transfer fluid by means of the
drain valve (3) until the operating pressure (see above)
is set.
• Close the ball valves of the SBS 1000.
• Remove the hoses from the SBS 1000 and screw the
caps onto the fill and drain valves
• Empty the contents of the hoses into the tank of
the SBS 1000 by opening the ball valves carefully.
Close the ball valves.
• Put the non-return valves in flow and return in opera-
ting position by opening the ball valves with an open-
ended spanner
• Manually put the solar thermal pump in operation at
the highest RPM level (see controller manual) and let
it circulate for at least 15 minutes.
• During flushing, bleed the solar thermal system several
times at the AirStopp, until the discharged heat transfer
fluid is free of air bubbles and increase, if required, the
system pressure to the operating pressure.
