DATA BOOK
RECOMMENDED REFRIGERANT LINES
Values are referred to “EQUIVALENT LENGTH” of the piping.
You are kindly requested to always refer to the
“INSTALLATION DIAGRAM”
for the allowable height difference and to properly select all necessary
components. Verify the need to use pressure limiting devices (pressure relief valves) where not already provided for by Directive 2014/68 / EU.
In some cases, the diameter of the refrigerant lines may not correspond with the diameter of the cooling taps.
This is completely normal. It is enough to provide a reduction fitting to adjust the diameter.
