Now the the system was prepared and checked for good functioning. A frequency controller was added to make a low noise speed control for the fan.
Some other refinements will be done when the system is on the 1th floor, eg sw adjustments to control the fan speed via RS485, compressor speed if allowed and more… But now the 70kg system was shifted via strong planks close to the window, of which the pane was removed. then moved outwards in direction of the ladder. When on the ladder, we positioned the system under the hole to the 1th floor, connected and pulled it up until it was there
