Caution
If the total circulating volume in the climate
system (excluding the heat pump volume) falls
below 40 litres, extra system volume is connec-
ted, for example volume vessel UKV (CP1) ac-
cording to the outline diagram above.
NOTE
If several climate systems (ECS 40/ECS 41) are
present, SAM 40 must be connected in parallel
with climate system 1. A circulation pump must
be used to ensure the flow over SAM 40.
