BA ROTEX GSU - 09/2007
GSU with installed Solaris system:
• Connect hose to the KFE cock of the control and pump unit (RPS).
• Top up the storage tank with water until the condensate overflows.
GSU without installed Solaris system:
• Either fix hose to the supplied hose nozzle and the hose nozzle to the upper side tank connection (see Fig 2-1, item. 12a) or
plug hose in the Solaris inflow connection (Fig 2-1, item 7).
• Top up the storage tank with water until the condensate overflows.
3. Topping up heating system and storage tank charging circuit
• Locate the hand lever on the 3-way valve (Fig 2-1, item 25) in the centre position (only possible if the system is not
electrically connected or in the as-delivered state).
• Connect the filling hose with return flow inhibitor (
½
") to the filling and draining fittings (KFE cock, Fig 2-1, item 35) and
secure from coming off using a hose clamp.
• Open water cock on the supply line.
• Open the KFE cock and observe the pressure gauge (Fig 2-1, item 31).
• Fill the system with water until the mark for the system overpressure is roughly in the centre of the green range in the
pressure gauge display.
• Shut off the KFE cock.
• Vent the entire heating network (open the system control valves).
• Check the water pressure on the pressure gauge again and top up with water if necessary.
• Close the KFE cock, remove the filling hose and return flow inhibitor from the filling and draining fittings.
Function check after start-up
The functioning of the heating must be checked after concluding the start-up activities (see section 4.4.2).
• Set the target temperature manually (see section 4.2.1).
Î
The boiler temperature and the storage tank temperature should increase slowly.
The gas condensation boiler charges the storage tank until the maximum adjustable storage tank temperature is reached.
There fter it switches over to heating mode.
• Check all heating lines for leakage in the hot condition.
• Set the desired mode (see section 4.1.1 or section 4.1.3).
WARNING!
Contamination of the drinking water is detrimental to health.
• Prevent the boiler water from flowing back into the drinking water line when topping up the heating
system.
The centre position is stable only if the valve is not electrically connected. The valve unlocks automatically,
if voltage is present on the drive motor for the valve setting AB-A (storage tank charging).
In order to ensure complete venting, the 3 way switch valve should be unlocked by pushing it in one hour after
system start-up at the earliest.
If you notice irregularities during the function check after start-up or during the initial days of operation, please
contact your heating supplier.
