17. Determine the correct amount of water to be added to or closed circuit fluid 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.
20 mm 0.6 litres 80 mm 2.4 litres 140 mm 4.2 litres
40 mm 1.2 litres 100 mm 3.0 litres 160 mm 4.8 litres
60 mm 1.8 litres 120 mm 3.6 litres 180 mm 5.4 litres
• Mark the required closed circuit fluid level to be obtained on the side of the solar
storage tank with a non permanent marker beside the clear hose, in relation to the
static level marked on the side of the solar storage tank during step 8.
e.g.: If the dynamic level is 30 mm below the text marking, then place a 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.
e.g.: 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.
