Commissioning; Control, Maintenance; And Cleaning; Draining - OEG 516008055 Notice De Montage Et D'emploi

Commissioning the storage tank is done in the following steps:
• flushing storage tank and all pipes
• filling storage tank until operating pressure is reached
• heating up the storage tank after filling is completed
IMPORTANT: All pre-assembled connections (e.g magnesium protective anodes and service
hatch) have to be checked for tightness before commissioning. After the first heating up,
all connections must be checked for correct seat or have to be retightened if necessary.
We assume no liability for damages caused by water.
IMPORTANT: With fresh-water and combined storage tanks, fill the drinking water side first.
IMPORTANT: Open vent valve on the heating water side.
IMPORTANT: The pressure on the drinking water side must not be higher than the pressure
on the heating water side.
IMPORTANT: For an optimal insulating effect, there must not be any condensing humidity
within the insulation. A damp insulation can be dried by lifting the top storage tank cover
temporarily during active operation.
IMPORTANT: Draining of fresh-water and combined storage tanks is performed in reverse
order to commisssioning. When maintaining the drinking water side, the heating water side
is to be made pressureless first.
The draining of the drinking water is performed after closing the shut-off valve in the cold
water supply line via the drain valve of the safety valve combination while simultaneously
opening all hot water valves of the connected functioning fittings.
When commissioning – and at least once a year – you have to test the correct function of
the safety valve. If the safety valve constantly drops, this is probably caused by contamina-
tion, the pressure in the water pipe exceeds the permitted value or the safety valve is defect.
If the pressure in the water pipe exceeds the permitted value, a pressure reducer has to be
installed.
IMPORTANT: During the heating, expansion water visibly leaks from the safety valve.
Do not close!
