– Loosen all screws from the flowmeter module GM0392 and pull out the module.
– Mark the hoses at the flowmeters and remove them.
– Place the cable of the ring sensor through the housing to the upper end of the backplane and put the hoses on the extension
module DK46 SCS 104 the same way they were removed.
– Mount the extension module in the front.
