ount of water to be added to or closed circuit fluid 17. Determine the correct am
to be drained from the heat exchanger if the dynamic level is either below
the text marking “MINIMUM FLUID LEVEL WITH PUMP OPERATING” or
more than 150 mm above this mark.
Each 100 mm of fluid level height is equivalent to three (3) litres of closed
circuit fluid.

mark 30 mm above the static level marked on the side of the solar
storage tank in step 8. It would be necessary to add one litre of water
to the heat exchanger.
Eg: If the dynamic level is 180 mm above the text marking, then place
a mark at least 30 mm, but no more than 180 mm, below the static
level marked on the side of the solar storage tank. It would be
necessary to drain between one litre and five litres of closed circuit
fluid from the heat exchanger.
