To fill the appliance, proceed as follows:
1. Open the stop valve (11) in the hot water pipe and, if present, the stop valves
(4) for the circulation pump (6).
2. Close the drain valve (9).
3. Open the nearest hot water draw-off point (14).
4. Open the stop valve (4) on the cold water side (A) so that cold water flows
into the appliance.
5. Completely fill the appliance. When a full water jet flows from the nearest
draw-off point, the appliance is full.
6. Bleed the entire installation of air, for example by opening all draw-off points.
7. The appliance is now under water supply pressure. There should be no
water coming out of the expansion valve (15) or out of the T& valve (3). If
there is, the cause might be:
- The T&P valve is defective or incorrectly fitted.
- The water supply pressure is greater than the specified 8 bar.
Rectify this by fitting a pressure reducing valve (1).
- The expansion valve in the protected cold supply setup is defective or
incorrectly fitted.
